Forecast: A taste of winter in late November

Even though our average temperatures have been getting cooler for some time now, and we're just days off the start of meteorological winter, this is our first powerful Arctic air mass of the season. Thankfully, our normal (at least of late) pattern featuring dry weekends continues today and tomorrow. After we get through today, winds lessen and we see at least a brief warming trend into early next week. Oh, there's some rain on the horizon too.

PM Update: Windy, becoming cold

Southerly breezes overnight pushed temperatures all the way to near 60 this morning, but showers and an Arctic front have knocked temperatures down into the low 50s this afternoon. By tonight, the combination of gusty winds from the northwest and falling temps will make it fell downright wintry.

Thanksgiving ice coats western Maryland

As a warm front pushed over a shallow wedge of cold air yesterday morning, a wintry mix of precipitation fell in central and western Maryland as well as northwest Virginia where temperatures hovered near freezing.

Forecast: Showers start Black Friday, then brisk

I know shopping in the rain sounds like a pain, but showers should be out by midday and they won't be terribly heavy to begin with. Then we deal with afternoon breezes and falling temperatures, which I know aren't fun either. So dress in layers if shopping all day and be prepared for changing weather. After this Arctic cold front passes through, it stays windy through at least Saturday night. On the plus side, we remain clear this weekend. Though, temperatures remain in the below average 40s. Hope you can try to get out and about to work off that turkey!

Forecast: Moist Turkey day, gray Friday

The trip over the hills and through the woods could be a little slick but I am betting that the afternoon clouds part, allowing you touch footballers to get out there! The real cold front crashes the party on Friday morning. Winds crank up and it cools down Friday night. That's a fair trade for sunny and dry weather through Monday.

PM Update: Showers late, chance of sleet N & W

Despite lots of sunshine, daytime highs in the 40s to near 50 along with a brisk wind from the northwest have made it feel fairly winter like out there today. Actual highs for the day happened around midnight most spots, and temperatures this afternoon have only moved stubbornly slowly upward off overnight lows. We're looking at mostly worry-free weather the rest of today for last-minute travelers, but once we get toward midnight the risk for showers and perhaps some sleet moves into the picture.

Weather forecast for royal wedding now, seriously?

The international community is buzzing about the upcoming nuptials of Prince William and Kate Middleton slated for April 29, 2011 in London. But will all the pomp and circumstance be dulled by dreary clouds and dampness or radiate under brilliant sunshine and warmth?

Howard Bernstein & Topper Shutt winter outlook

The start of meteorological winter (December 1) is just one week away and it appears the last of the region's winter outlooks has been released. Like the ones that came before it, the outlook of Howard Bernstein and Topper Shutt of WUSA-TV9 follows the tired format of recapping last winter with all sorts of dramatic snow B-roll, talking about what La Nina is, and concluding by predicting less snow.

Arctic dust storms: really?

When one thinks of dust storms, I suspect the mental images that appear include the Dust Bowl of the 1930s in the U.S., West African dust blowing over the Atlantic, and the desert environments of the Middle East, Australia, and China. But I doubt Alaskan glaciers come to mind. Consider also the occurrence of glacial related dust storms in Iceland and a possible connection to global warming, and head-scratching might be the principle reaction.

Forecast: A colder, quiet day before Thanksgiving

For all the extreme weather affecting the West and into the Central U.S., conditions in the D.C. area will be about as quiet as can be for the big travel day before Thanksgiving. Some showers may threaten for Thanksgiving Day itself here in the D.C. area and on Black Friday too, but neither look to be a washout.

Doug Hill & Doug Kammerer winter outlooks

We published our winter outlook several weeks ago, predicting modestly above average temperatures and around average snowfall. Since then, a number of television forecasters have released their outlooks. The latest two, issued yesterday, come courtesy chief meteorologists Doug Hill at ABC7 and Doug Kammerer at NBC4. The one thing all of these outlooks have in common is that none of them are predicting above average snow in the mid-Atlantic region. Want a winter prediction for above average snow in this region?

PM Update: Showers to end, becoming clear & cool

Showers associated with a cold front moving through the region this afternoon have interrupted an unseasonably mild day. On winds from the south, temperatures had ascended all the way into the upper 60s (69 at DCA). The showers should cutoff by dark as cooler air gradually trickles into the region.

Crazy, extreme weather leads up to Thanksgiving

The combination of a massive Arctic outbreak out West, a warm surge in the East and powerful storm in the transition zone is wreaking weather havoc as the Thanksgiving holiday approaches. Even Alaska is contending with unusual weather, as unseasonably mild air bumps up to the Arctic circle, bringing widespread rain and ice rather than the customary snow.

Forecasting "turkeys": predictions gone awry

Recently, I noticed that a Florida senior center was planning a presentation entitled "Tremendous 'Turkeys' of History." Included were: Fulton's steam engine, initially deemed a folly; Disney's Snow White, considered a certain flop when (and if) it reached the theaters; and, of course, Ford's Edsel, anticipated as the "car of the future," but which turned out to be the greatest design disaster in automotive history, although some considered it a car ahead of its time. What about U.S. weather forecasting "turkeys?" We can all think of some, but what were some of the most conspicuous since the founding of the Weather Bureau, now the National Weather Service (NWS), in 1870? I did some research (1) and, because it's now almost winter, am limiting the cases to blown, or almost blown, snow forecasts, which usually leave an indelible mark on our collective memories.

Forecast: Warmer today, chance of PM showers

Changeable November weather continues to complicate our holiday weather picture. If you have travel plans west of here, you may run into weather-related delays tomorrow as a storm system affects the Midwest. That storm reaches our region by Thanksgiving in the form of a warm front (rain) and then on Black Friday in the form of a cold front (more rain).

Climate Central update on La Nina, October temps

Take a look at this very well-produced update on La Nina and October temperatures from Climate Central, a nonprofit, collaborative group of scientists and communicators whose mission is "to create a bridge between the scientific community and the public, providing clear, honest, nonpartisan, and up-to-date information to help people make sound decisions about climate and energy."

PM Update: Staying mild through tomorrow

After some dense fog and a dew-filled start to the day, clouds broke for a pretty glorious one for this time of year. Highs have reached near 60 and into the low 60s across the area as a south wind pumps in warmer and more "humid" air. Enjoy the warmth the rest of today and tomorrow, because cooler air is scheduled to invade as we get to Thanksgiving and beyond.

Cold blast over interior West to fizzle East

The early season cold snap diving into the Rockies and western Great Plains is stunning. By Wednesday, large portions of that region will experience lows below zero and highs in the single digits.

A year after climategate, applying lessons learned

A year ago at this time, while policymakers and journalists (including myself) were gearing up for the Copenhagen Climate Summit, a story began percolating in the blogosphere about a voluminous trove of stolen emails sent between prominent climate scientists. The emails purportedly contained evidence that climate scientists had fudged temperature data and interfered in reviews of studies that did not adhere to mainstream views of manmade climate change. As numerous investigations have found, the scientists involved in the emails did not commit scientific fraud, and the emails' scientific significance was negligible.

Forecast: Mild Monday, late week cooling

Two cold fronts push through the region this week, knocking temperatures down in two steps. The first front comes in tomorrow afternoon, dropping temperatures from above average Monday and Tuesday to average by Wednesday. The second front arrives Thanksgiving, dropping temperatures to below average levels Black Friday though the weekend. With each front, we'll run the risk of showers.

Forecast: Seasonable chill makes brief return

We cool off today a good 10 degrees from yesterday's fabulous mid-60s, though few should be surprised by highs in the 50s as we move into the last part of November. The seasonable chill combined with partly sunny skies make for nearly perfect leaf-raking conditions, if you're fortunate (unfortunate?) enough to have a lawn anyway. We luck out with a brief early-week warm spell, before a duo of cold fronts bring rain chances and then much cooler weather in time for the holiday.
