Capital Weather Gang: November 28, 2010 - December 4, 2010

Forecast: Cold holds. Flurries tonight?

We're not staring down any major weather makers locally, but this weekend won't be terribly pleasant. Though not highly likely, a few flakes could fall from D.C. and south overnight, with any accumulation even further south. Cold is here to stay for a while. Winds are coming back.

PM Update: Cold weather is here to stay

The cold reality of winter settled in today across the area, with highs only in the low 40s to near 40 for the second straight day, and the cold here to stay well into next week at least. Tomorrow night's snow threat should stay well to our south. But winds are a different story - they're poised to create quite the chill Sunday and into the new work week.

Your Call: How much snow in D.C. this winter?

Forecast: January-like temps to continue

It's cold again today and it's going to stay that way for some time it seems. Our weekend snow threat has dwindled further, but we could still see some flakes in the sky into next week. The other story? Wind, especially Sunday and into early week.

PM Update: Cloudy, chilly and wintry

For the first time since last February, the air has a distinctively "wintry" feel. The clouds coupled with a breezy chill have capped temperatures in the low 40s after morning lows at or below freezing. Indeed, this is the coldest day since February 26. Cold, cloudy conditions continue tonight into tomorrow.

December 5 snow threat decreasing

The threat that the Washington area will receive its first touch of snow on Sunday keeps waxing and waning from one computer run to another. This potential snow producer is nothing like the monster snowstorms we experienced last year. Instead, the area will be flirting with a clipper type system, one that comes from the west-northwest and then passes to our south as opposed to last year's big storms that came up from the Gulf States with copious amounts of moisture. And this clipper may track too far south to give us any snow at all.

The December 5th coincidence

Last year, on December 5, the Washington area experienced it's first snowstorm of the season. That was the fifth time in eight years that Washington had a snowstorm on December 5.

Forecast: Wintry temps to dominate

The temperatures that we are stuck with for the next week are more typical of the heart of winter than early December. Snow chances are low despite the cooperative temps. A developing storm flies by to our south Saturday night offering just a chance of flurries. Its main impact is going to be wind chills that are ugly on Sunday and Monday.

PM Update: Cold settles in, here to stay

Warm morning temperatures and severe weather are just a memory now, and cold air looks to stick around a while. Happily, we'll see some sun tomorrow even if temperatures stay considerably below average.

Big snows in UK: Snowmageddon London-style

While winter is finally beginning to assert itself in the Eastern U.S., bitter cold, wind, and snow have been plaguing the United Kingdom (UK) and western Europe for weeks. Snow in the last 24 hours has closed London's Gatwick airport through at least tomorrow morning. Roads and trains have also been disrupted.

Welcome winter! Temps tank behind storm

On the first day of meteorological winter, a stunning cold frontal passage has abruptly ended autumn. In the course of minutes, temperatures have dropped 10-20 degrees behind the gusty showers and storms that doused the morning commute.

Forecast: Stormy a.m. before cold air blows in

Heavy showers and possibly thunderstorms - with the potential for damaging winds, an isolated tornado and flooding of low-lying areas - make getting around difficult through much of the morning. A breezy blast of cold air follows this afternoon, leaving us chilly and probably precipitation-free tomorrow through the weekend.

Tornado watch extended east (then canceled)

The tornado watch in effect through 10 a.m. has been extended in the eastern suburbs until noon. In the District and points west, the watch has been allowed to expire. Though some gusty showers continue north and east of Fauquier and Prince William counties, the worst of the storms is over. So a lot of us can exhale, if the gusty winds and plummeting temperatures don't take our breath away. Reports indicate 20 degree temperature drops behind the storms.

PM Update: Heavy rain & wind late, then cold

The passage of a warm front has pushed temperatures into the balmy low 60s this afternoon as we now await a cold front that will tear through the region early tomorrow. Don't expect major weather problems for this evening's commute, but tomorrow morning's is likely another story.

Flooding, thunderstorm risk for Wed. a.m. rush

The timing of the big, bad cold front to huff and puff and blow through the region tomorrow could not be worse. At the moment, the frontal passage looks to occur between 5-10 a.m. from west to east across the metro region.

Forecast: Mild with rain arriving, heavy tonight

Winter is speeding toward us with sharp temperature swings and a chance of some late weekend wintry weather. In the transition, we'll contend with heavier showers and maybe thunderstorms tonight into about midday tomorrow.

A look into early December: cold likely

The pattern early in December definitely is trending towards a colder than normal pattern. The picture is a murkier in terms of our chances of seeing an early December snow but the odds of getting snow appear to be increasing.

Forecast: Wild week - Sun, storms & winter's return

The weather word of the week is volatility as a midweek front brings big, abrupt changes. Today marks the calm before the storm and even tomorrow is relatively tranquil before the front unleashes its fury Tuesday night into Wednesday with heavy rain, gusty winds and possible thunder. Behind the front, it turns much colder for the second half of the week.

Forecast: Bright but chilly, without the wind

The bright side to today's continued chilly weather, beyond the sunny skies? Yesterday's whipping winds are a thing of the past. Temperatures do edge higher to start the work week before a potentially soaking rain for the area late Tuesday into Wednesday.
