Predicting where the Gulf oil will go

Mother Nature is no longer helping matters in the Gulf of Mexico, where the Deepwater Horizon oil rig exploded and collapsed on April 20. For a time, winds mainly from the north and west had kept the sheen of expanding oil in the Gulf of Mexico away from the Gulf Coast. But that changed starting Wednesday night, when winds shifted and began to blow from a more southerly direction. The onshore flow is expected to persist at least through the weekend, raising the prospects for devastating effects on the environment, wildlife and economy.

Forecast: Warm, warmer, then hot & muggy!

Our warm-up gains momentum today, then shifts to a higher gear over the weekend. Say goodbye to those crisp mornings, and hello to increasing heat and humidity, too. The weekend will feature all the hallmarks of summer, including a chance for afternoon and evening thunderstorms. There's good news for those not ready for a permanent shift to summer -- both temperatures and humidity look to moderate as we get into next week.

PM Update: Preparing for a taste of summer

Here we go... back to pleasant springtime weather! Of course, it may only last one or two days, depending on your definition of "pleasant" and "spring." Highs rising to around 70 and into the low 70s feel pretty mild compared to yesterday, even with some gusty breezes. Temperatures only go up in the coming few days, and at least one (if not more) of the 'H' words is likely to be uttered a few times before Sunday is over. But not yet. This evening looks like a great one for any outdoor activities.

Hypothermia in summer: The storms of 8/3/2002

More people die from hypothermia in summer than in winter. Subfreezing temperatures are not a requirement for hypothermia to occur. All that is needed is for weather conditions or water temperatures to lower one's core body temperature below 95°F. This can happen in the summer, when people are less prepared for cold conditions. If I would've read the paragraph above before Aug. 3, 2002, I probably would'nt have paid too much attention. Well, on Aug. 3, 2002, I learned first-hand that even during summer, hypothermia can be as dangerous a threat as heat.

Forecast: Better days ahead (warmer and sunnier)

Are you ready for the big warm-up? Like a continental-sized see-saw, a crashing jet stream out West and cooling will result in a northward surge in the jet stream here on the East Coast and warming. How high will we go? Well, it looks like we could reach up to around 90 in places this weekend and 80s are a real safe bet starting tomorrow. A cold front arrives Monday to send our end of the see-saw back down.

Eight years ago: Tornado devastates La Plata, Md.

On this day in 2002, the strongest tornado on record to hit Maryland flattened portions of Charles and Calvert counties, with the town of La Plata ground zero. The tornado was classified as an F4 (on the old Fujita scale) when it ripped through that town, indicating it possessed winds of 207-260 mph.

Forecast: Warm-up waits one more day

This is a tough time of year for wardrobe consistency. In typical spring fashion, the wardrobe should get a good workout as we shift from cool and breezy today, to warmer and sunny Thursday and Friday, to very warm (some might say hot) and even a little humid over the weekend. So, we go from jackets and long pants today, to shorts and sandals Saturday and Sunday. Overall, it's a pretty good forecast if you have outdoor plans, though we'll have to see if any thunderstorms pop up this weekend.

Saturday's tornadoes: Success amid devastation

As of last week, the nation's tornado activity for 2010 stood at record lows -- at least when adjusted for the "inflation" produced by ever more spotters, chasers and video cameras. But the relatively placid spring turned violent on Saturday across the Deep South as a swarm of tornadoes ripped from Louisiana to Tennessee. The NOAA Storm Prediction Center (SPC) tallied 69 preliminary tornado reports -- among the largest 24-hour totals logged in recent years -- from 7 a.m. CDT Saturday to 7 a.m. Sunday.

Forecast: Cool today, then a steady warm up

Up, up and away! That's the direction temperatures are heading as the week progresses. Temperatures 10 degrees below average today will transition to 10 degrees above average by the weekend. Now that's a warming trend. While temperatures experience a steady rise, the dense cloud cover abruptly dissipates -- departing this afternoon, with abundant sunshine for the next several days thereafter.

PM Update: Showers, some thunder, into tonight

A few showers this morning gave way to a midday break in the action, but more showers and thundershowers have formed this afternoon. Showers and a few rumbles of thunder are possible for the remainder of the afternoon and into the evening. Otherwise, clouds and the pesky marine air that pushed back south across the area last evening have been slow to budge today, capping highs in the low-to-mid 60s.

Forecast: Showers, cooling, and then warming

It's a bit of a topsy-turvy week in the weather department. Today it's seasonably mild but with the threat of rain before we cool down tomorrow and Wednesday. Thursday and Friday we'll enjoy some beautiful days, warming back up into the 70s. Warm conditions probably stretch into the weekend, but the proximity of a front may bring back the chance of scattered late day thunderstorm activity.

Forecast: Chance of storms to close out weekend

There's some risk of an active afternoon and evening today as the storm system that brought strong tornadoes to the South moves into our area. We don't expect anything of that magnitude around here but we could see some stronger storms late this afternoon and this evening. Shower and thunderstorm chances stay with us into Tuesday but by midweek we begin to clear and start a slow warm-up towards the weekend.

Severe storm, tornado season cranks up

After a quiet start to the spring severe weather season, more than 30 tornadoes ripped across the Plains on Thursday with more than 100 severe reports altogether. The Storm Prediction Center (SPC) expects the severe threat to continue today into tonight, shifting several hundred miles to the east.

First the great news: Today's sunny and 70 will be pretty amazing! However, clouds increase tonight, and the likelihood of showers and thunderstorms isn't too far behind. On the bright side, there is hope that neither Saturday nor Sunday will be total washouts, and temperatures remain mild through the weekend. But we'll have a hard time shaking the shower chances even as we get into next week.

Forecast: Two pretty nice days ahead

At first glance this forecast looked like a loser, but on closer examination I think it's going to be better than some expect. Today will be more sunny than cloudy despite the chance of an isolated late-afternoon shower or two. Moreover, Friday will definitely be a winner with sun and mild temperatures. Though the weekend won't be sunny and beautiful, showers may be more miss than hit at times -- with the best chance of rain Saturday night into early Sunday -- and highs in the mid-60s to near 70 won't be far from normal.

Earth Day turns 40: Celebrate with local events

Forty years ago, the inaugural Earth Day took the country by storm. On April 22, 2010, over 20 million American citizens, including teachers, students and community leaders in more than 1,000 cities and towns across the country, raised awareness of environmental degradation in their communities and demanded government protection for the natural environment.

Forecast: Briefly cooler today with showers

If Mother Nature had a suggestions box, it would probably be pretty empty right now, other than a "quit it, already" leftover from after the February snowstorms. Customer satisfaction has to be quite high considering the lopsided count of spectacular days vs. stinkers this spring. While today may not be a total stinker, it will most certainly draw complaints with showers and cooler temperatures. Nicer weather is back for most of tomorrow and Friday before showers threaten again this weekend.

Showers should diminish as the evening progresses, though some mist or drizzle may remain. My hunch is they'll get this game in, although there may be a rain delay if the steadier showers expected for the afternoon last into early evening.

Weather sayings: Do they have any value?

In earlier times, before weather satellites, radar, and even the U.S. Weather Bureau (founded around 1870), farmers, sailors, etc. needed an easy way of associating the precursors of weather changes with the actual weather that followed.

Forecast: Sunny and warmer today

The combination of dominant sunshine and warmer temperatures may make today a contender for best day of the week. While still cool, this morning should start out a bit warmer than yesterday, allowing the area to make a solid run at 70 degrees. After a cooler day tomorrow with possible showers, some sun and slight warming returns for the end of the week. Weekend rain chances are still looming. So get out there and enjoy today if you can!

Iceland volcano unlikely to cause global cooling

The eruption of Mt. Eyjafjallajokull in Iceland has had a chilling effect on air travel, but unless the eruption starts lofting far greater amounts of volcanic material higher into the atmosphere than it has to date, or continues unabated for months, the volcano with the tongue-twisting name probably will not join the ranks of famous climate-altering volcanoes, such as Mt. Tambora in Indonesia and Mt. Pinatubo in the Philippines.

Forecast: Slow and steady warming

For the first several days of the week, we'll edge closer and closer to 70 degree territory. By mid-to-late week, we'll reach it. Warmer weather fans we'll be glad to know that in a week, 70 will, in fact, be average. Having said that, we've been no stranger to 70-degree weather this month despite our coolish weekend: the average high has been in the low 70s. While temperatures have been warmer than average, it's been drier than average. And we'll be dry for a lot of this week, although showers may threaten this weekend.

Forecast: A chilly Sunday, but turning milder

When the last several cold fronts have passed through the region, temperatures have quickly rebounded into the 70s and 80s. This time the warm-up won't be so fast, but I don't think we'll have much to complain about. While today holds a bit of a chill, we'll soon be rewarded with seasonable temperatures warming into the mid-to-upper 60s and plenty of sunshine.

Cooler than average days have been tough to come by since early March, but we'll experience a pair of them this weekend.

Breezes from the west really warm us up today ahead of a cold front approaching from our northwest. The best chance of showers and storms associated with the front conveniently waits until later this evening into the overnight, and the rain threat should quickly diminish as we get into the weekend. While both Saturday and Sunday will be dramatically cooler than today, with sometimes gusty winds to boot, times of sun may still make the outdoors somewhat inviting.

Why is climate change more popular online?

Here's a question I've been pondering lately: Why is climate science a wildly popular topic on the Web every day, yet it barely registers on the radar screen of the traditional press, unless of course there is an outbreak of extreme weather or a scientific brouhaha like the so-called 'climategate' affair (which was originally pushed by bloggers)? A closely related question is why skeptics of the well-supported conclusion that recent climate change is predominately manmade dominate the conversation online, but not in the traditional press?

Today will be a picture perfect one; the kind you want to save for those dog days of summer. However, we will then embark on a roller coaster ride of weather starting with a summery day on Friday capped by some late-evening thundershowers. Then we dive down to a weekend of much cooler temperatures. Isolated pockets of frost are even possible Sunday morning in the colder suburbs. Finally, we pull into the station with a seasonable day to start the work week on Monday.

Bluebells and Redbuds at Battlefield Park

The bluebells and redbuds were blooming at the same time this past weekend at the Manassas Battlefield Park, about a week-and-a-half ahead of schedule due to our recent warm weather. It was a beautiful scene along Bull Run near the Stone Bridge, with bluebells providing a carpet of blue along the forest floor and red buds providing splashes of lavender along the stream's bank.

Forecast: Staying in the springtime groove

If there's one thing we Washingtonians feel entitled to (OK, there's probably more than one thing), it's a sufficient spring. Not a couple perfect spring days sandwiched between winter cold and summer heat, but rather a several-week stretch of moderate warmth. To a large degree, with exceptions such as last week's mini heat wave and yesterday's cool and damp one, spring 2010 has delivered. That trend continues over the next several days, though not without a chance of showers toward the weekend.

Atmosphere's revenge? Monarchs in short supply

Normally this time of year, millions of real-life monarch butterflies are migrating from their winter haunts in Mexico toward the northern U.S. and Canada. This year, however, it seems the atmosphere has taken revenge by devastating the butterflies' winter sanctuary in the mountains of Mexico.

Forecast: Cool & damp then warming back up

Temperatures take a 10-15 degree tumble today (compared to yesterday), so if you've been heading to work jacket-free of late, re-think that this morning. You also should bring along an umbrella, as damp flow from the east and a weak disturbance passing by combine to increase showers chances as the day goes on. While today's highs will be cooler than average, we should see above-normal levels again by Thursday and Friday with warm 70s. Over the weekend, we may dip back into the 60s with showers possible again Saturday.

Is April snow in D.C. becoming more rare?

Despite the early-April warmth (and maybe to spite people who consider it a four letter word) some snow lovers can't ever get enough. So before we put to bed discussion of snow chances 'til 2010-11, let's take a look at what April typically has to offer metro region snow hounds. By the books, April provides close to nothing in the snow department. Nonetheless, snow does occasionally stick in April and an analysis of the stats tells an interesting story about its characteristics and long-term trends. Possibly the most important conclusion of my snow analysis is that snow of any consequence (of say, at least an 1") has always been fairly rare in the D.C. area during April. Interestingly, April snow might be a dying breed, at least in the city itself.

Forecast: Sunny start to week, a little cooler

Since March began, more than 85% of our days have been warmer than average. The first week of April was the warmest on record. But temperatures this week will be pretty average, mainly holding in the 60s for highs. We'll also see a couple rain chances: Tuesday into Wednesday and once again late Friday into Saturday. Not the nicest of the weeks, but could be worse.

Forecast: Continued stretch of sun for now

We'll warm up enough today to significantly improve on yesterday's pleasant, but slightly brisk conditions and to close out the weekend in style. Above-average temperatures briefly return before a dry cold front moves through to push us back to our climatalogical norms.

Forecast: Sunshine and a modest warm-up

The chilly air that brought the abrupt end to our midweek heat wave won't have much staying power. High temperatures bottomed out yesterday, when they were held to the upper 50s. Today, we start to warm back up with temperatures climbing into the 60s. And on Sunday, we're back into the 70s. Sunshine all weekend long will delight outdoor enthusiasts and it looks to hang on into early next week though temperatures will cool back down a bit.

Normally, our weather is not so normal

A few weeks ago, some of you may remember my article, "Believe it or not, D.C.'s is a Climate to Relish," in which I argued that, despite our winter of record-setting snow, the D.C. area's climate -- the highs, the lows, the extremes and the normals -- is relatively tame compared to other parts of the country. As a postscript to that article, and in the wake of yet another period of notable weather (this time a stretch of summer heat in early April), I will now focus on the latter of those climate components -- the "normals."

Forecast: Welcome back, spring!

Today's winds and considerably cooler air are courtesy last night's stormy cold front. Hope you didn't sustain any storm damage? While temperatures closer to average over the next several days will feel cool compared to the recent heat, we'll still be able to revel in plenty of splendid sun.

The pollen, my friend, is blowin' in the wind

The single biggest complaint I've heard about this week's weather is neither the above-normal heat, nor the crowds of tourists ... It's allergies. The sudden burst of warmth and sun combined with the lack of rainfall over the past several days have sent trees that were snow-bound just weeks ago into a reproduction frenzy. Tree pollen has been the main culprit.

Forecast: Season's first severe t'storm threat

Our premature taste of summer may end with a bang today with the threat of strong thunderstorms late this afternoon. More typical spring conditions will follow the storms. Tomorrow will feel almost cold, but surprise, the readings will actually be very close to normal for this time of year. It may even be chilly enough for pockets of frost in coldest areas tomorrow night. The weekend will be very pleasant with light winds and moderating temperatures.

Thunderstorms may add to stadium fireworks

Thunderstorms are likely to sweep through the area sometime during the game. The good news is they are likely to be fairly fast moving but the first rain delay of the season is a distinct possibility.

Forecast: April heat wave still in high gear

My goodness, was yesterday a warm one or what?... The unusual warmth hangs around through tomorrow, before a cold front passing through tomorrow night ushers in much cooler, but overall still pleasant, weather for Friday and the weekend. The only chance of disruptive weather over the next several days comes later tomorrow into tomorrow night.

Easter Sunrise in Washington

It was 6:10am on Easter Sunday morning and I was crawling toward the Tidal Basin in a blossom-related traffic jam. I was hoping to do a sunrise photo shoot, but I also had to be back for an Easter service at 8:00am to watch my kid sing in the choir. With sunrise at 6:48 a.m., there was not much time to photograph.

March recap: The month of melting snow piles

As high as the snow piles from February's epic snows reached into the sky, most were no match for March's mild temperatures. Melting occurred uninterrupted in the warmer parts of the region. As I mentioned last week, the temperature did not dip to freezing the entire month at Reagan National Airport (DCA), for the first time on record. In fact, the average low temperature at DCA was warmer than it has ever been since records have been kept.

Forecast: Spring sunburst offers summer sizzle

A large ridge of high pressure will be anchored over the area for most of the next three days. The result will be impressive early season heat for the entire East Coast. Now, these 80s will not equate with the typically more humid summer versions, but we could notice a slight increase in humidity in the coming days. Tomorrow has the best chance to see some areas touch 90 degrees for the first time this year.

TV weathermen should re-think climate coverage

It's no secret that weather forecasters and climate scientists don't see eye-to-eye about global climate change. Weather geeks, including TV meteorologists ('TV mets,' in media lingo), tend to be far more skeptical that human activities are changing Earth's climate than climate scientists, the vast majority of whom view the human influence as a near certainty.

Forecast: A midweek spell of summer-like heat

What a spring we've had so far. Only two days in the past 30 have been cooler than average and we've had 11 days with highs at least 68. Today will be another spring-like day but tomorrow and Wednesday we skip a season with conditions more typical of summer. Temperatures will climb at least into the mid-80s with some spots making a serious run at 90, especially Wednesday. It will cool down briefly Friday, but temps gradually rebound over the weekend.

Forecast: A whole lot of "nice"

I'm running out of ways to say "nice" for this recent stretch of weather we're enjoying. There's not much change looming either, and what little chance for showers we do have, Monday night/Tuesday morning, will likely occur while we're all asleep, clearing out in time for some 80s by mid-week! Any meaningful cool down waits until at least Thursday.

Forecast: Weekend weather to wow us

It's a simple, straight forward, and sublime forecast: sunny 70s today, tomorrow, and right on into Monday. This is the kind of weather that's more common in San Diego, Ca., giving it the reputation as having the near-ideal climate. How long will this southern California-style weather last here? I can say at least through mid-week, but don't count on it forever. This month is known for its mood swings around here. As I wrote two years ago, April weather can be both amazing and appalling.

A cherry blossom bird's-eye view

I had a unique opportunity to view Washington's world-famous cherry blossoms from above on Thursday afternoon. As I looked down from my flight approaching Reagan National Airport, I saw the beauty of the blossoms on a larger scale than most get to witness.

Forecast: Gorgeous string of near-perfect days

It really doesn't get much better than this in the nation's capital. I mean, not only is it sunny and warm, but the marvelous weather coincides with the Easter holiday, bursting cherry blossoms, and the first home games for the Nats and D.C. United. The low-humidity warmth should be perfect for just about anything, be it a bbq, patio party, frisbee game or walk on the Mall. Get out and enjoy. With some sunscreen on hand too, please.

Forecast: Beautiful, warm sunshine into Monday

What a great spring weekend this will be! Start it early if you can. The only people that might lodge a complaint are the kite flyers for the lack of wind and allergy-sufferers. Otherwise, it is prime blossom-viewing and picnic in the park time. Please don't forget the sunscreen. We're looking to cross the 80 degree mark for the first time since October 9 and only fall a few degrees short of record highs (87-89) this weekend. If we manage to find clouds in the sky it probably won't be until Easter Sunday and those will be just enough to make for nicer pictures.
