Capital Weather Gang: June 6, 2010 - June 12, 2010

Forecast: Sticky & steamy with chance of storms

The low humidity we were treated to over four of the last five days is outta here. Now the stickiness ramps up - peaking tomorrow into Monday. The associated deep tropical moisture will fuel any thunderstorms that form, impacting some areas with very heavy downpours - especially in the evening hours. We won't lose the humidity until Tuesday.

PM Update: Summerlike through the weekend

If you throw out Wednesday, this was a pretty great week of June weather. Today is no exception as highs rise into the mid-80s under partly-to-mostly sunny skies and continued low humidity. Soak up this last bit of this less-sweat weather, because tomorrow should feel a good bit different outside as we get another solid taste of summertime conditions to come.

What makes hail clear, not cloudy?

On May 15, we posted a story on hail that included a photo and video of hailstones that fell from a severe thunderstorm the previous day, on May 14. The photo featured in our post showed a hailstone that was fairly clear and irregularly shaped compared to the other spherical hailstones. I also heard a report of a clear and flat-shaped hailstone that fell from the same storm a few miles south of Manassas. I decided to research how these clear and irregularly shaped hailstones might have formed.

Forecast: Muggy weekend, with Sunday showers?

Today is easily the nicest of the next several days and a great way to end the week. But humidity builds through the weekend with our classic summer showers and storms threatening, mainly late Saturday and Sunday -- so the weather should be mostly fine for tomorrow's World Cup watching in Dupont Circle. Hopefully our heat and humidity take a bit of a break come Tuesday, but it's hard to say for sure.

PM Update: Low-humidity warmth presses on

The sun returned today and brought summerlike conditions with it. Warm west and northwest winds coming off the mountains have gusted to around 20 or 30 mph, but on a day like this it's no real issue, except perhaps if trying to keep your hair from being messy. Highs have climbed into the upper 80s most spots, with a few places threatening to touch 90 before peak heating winds down. Humidity is thankfully bearable though, for now at least.

Why is oil spill hard to predict? Look to the clouds.

The BP Gulf oil spill has become the most recent example of a "Black Swan" -- i.e., an improbable, unpredicted event having tremendous impacts. Retrospective analysis might demonstrate the Deepwater Horizon explosion and resulting massive flow of oil into the Gulf was a relatively likely "accident" waiting to happen. Without benefit of hindsight, though, it's been an event totally unanticipated with far-reaching consequences and one due to human failings, not an unavoidable natural disaster (e.g., earthquake, hurricane). Avoidable or not, we are in the position now of having to manage to the extent possible what heretofore was an unimaginable crisis. The ability to manage the crisis is dependent upon at least three fundamental questions: Exactly how much oil has spilled? Where is the oil located? And where will it go? Unfortunately, there appears to be considerable uncertainty on answers to the first two questions, while the third is probably unanswerable beyond a few days in advance. A reasonable analogy is predicting the development and motion of a cloud where imperfect measurements of its dimensions, location and background wind field are magnified over time by imperfect forecast models. To extend this analogy consider the following...

Forecast: Sun, low humidity deliver two great days

The clouds are long gone, and so is the sogginess. Even with warmer than average afternoon readings anticipated today and tomorrow, this is delightful summer weather. All good things come to an end much too soon with humidity levels already climbing Friday night as a warm front moves through. The passage of this front sets the stage for a 3-H weekend (you know: hazy, hot and humid)! With lots of instability in the air, thunderstorms could pop late in the day and into the evening both weekend days.

PM Update: Clouds and showers plan their exit

It's a damp and dreary day out there, but not terribly rainy overall. Showers, and perhaps a rumble of thunder, continue to push through the area this afternoon and the risk should persist into the evening hours. If you're already sick of the clouds, they are not hanging around for long, so just wait for tomorrow.

Unmasking disinformation, from tobacco to climate

It's no secret that many climate skeptics have ties to the fossil fuel industry, or are ideologically opposed to the policy implications of mainstream climate science, which holds that emissions of greenhouse gases are causing global temperatures to increase. This has been explored in numerous books, most notably in Ross Gelbspan's "The Heat is On" and "Boiling Point," as well as the more recent work by James Hoggan, "Climate Cover-Up: The Crusade to Deny Global Warming."

Forecast: Showery today; sunny end to work week

As we glow in the aftermath of Stephen Strasburg's stunning start, it's going to take a lot more than rain to dampen our spirits. Furthermore, today's wet weather is just a blip in an otherwise flawless work week weather-wise. After today's showers, enjoyable sunshine comes back Thursday and Friday. We can save all of our weather complaints for the weekend, when the humidity hits us hard.

Doug Kammerer new chief meteorologist at NBC-4

When the "dean of D.C. weather" Bob Ryan left NBC-4 (WRC) to join veteran forecaster Doug Hill at ABC-7, it left a massive hole for NBC to fill. Yesterday, the station announced it was pinning its hopes on Philadelphia forecaster Doug Kammerer who will become its chief meteorologist in August (as reported by the Post's Lisa de Moraes yesterday). Kammerer, who grew up in Herndon, Va. joins veterans Tom Kierein, Veronica Johnson, and Chuck Bell on NBC-4's weather team.

Forecast: Terrific today; wet Wednesday

Canadian high pressure can be such a gift when we are in the summer months. Yesterday's high of 78 at National Airport was four degrees cooler than normal, while Dulles was a full six degrees cooler than climatology. The cool air mass is with us again today and will not come at the expense of sunshine either. Things change quickly tomorrow though as low pressure arrives to bring showers, storms, and clouds.

PM Update: Enjoying a break in the heat

Sometimes gusty northwest winds, plus passing clouds and even a shower or two northwest of the city, have helped keep temperatures in the mid-and-upper 70s this afternoon. The forecast for tomorrow could also be termed "pretty sweet" before rain chances return and threaten to sully the midweek.

Did Sunday's storms have more bark than bite?

Tornado watches were hoisted Sunday across most of the northeast United States, including here in the D.C. metro area. But the results, outside a few reports of wind damage, did not seem to match the outlook from some forecasters.

Forecast: Feeling fresher and finer

The last five days we sweated through high temperatures ranging from 89-92 coupled with sauna-like humidity. I think we'll all now appreciate high temps from 79-82 for the next five days with humidity only really a factor on Wednesday, which could be on the wet side. Unfortunately, heat and humidity may build back into the region next weekend.

Alert: Tornado Watch for entire area until 8 p.m.

NOAA's Storm Prediction Center has issued a tornado watch for the entire region and much of the mid-Atlantic and Northeast as a strong cold front interacts with very humid, unstable air over the region. The watch is in effect through 8 p.m. tonight.

Forecast: Storms to spell end of heat wave

We're almost through this early summer stint of heat, humidity, and storm chances but we'll have to endure one more day to get our reward. After a cold front finally passes through today relief will filter in. To start off our new week, we'll have almost perfect conditions with sun, drier air and temperatures around 80 degrees before a new system threatens with more rain by mid-week.
