FORECAST IN DETAIL

A powerful low pressure system stuck in the North Atlantic will continue to feed cold air downward into our region through the next several days. Unfortunately, it still wants to generate some breezes that will provide a wind chill effect. However, these levels are not nearly as painful as what were experienced over the weekend. In fact, temperatures will ease upward ever so slightly in the coming days (but remain colder than normal).

Today (Tuesday): A mix of clouds and sun, and you might see some flurries again, especially the farther north and west of the city you go. Highs should be in the low-to-mid 30s with breezes around 10-15 mph from the northwest and some higher gusts. Confidence: Medium-High

Tonight: Variable sky conditions with lows ranging through the low-to-mid 20s (suburbs to city). Winds will be generally light. Confidence: Medium-High

Keep reading for the forecast through the weekend....

Tomorrow (Wednesday): The pattern should repeat with clouds and sun and slightly warmer highs -- middle 30s in most areas. Winds persist from the northwest and probably increase a bit, up to around 15-20 mph with occasional higher gusts. Confidence: Medium-High

Tomorrow Night: Partly cloudy skies with temperatures in the low-to-mid 20s again. Confidence: Medium-High

A LOOK AHEAD

Thursday looks to highlight morning sunshine and afternoon cloudy skies as a weather system approaches the area. Temperatures will push warmer with mid-to-upper 30s favored for highs. Confidence: Medium

Thursday Night could feature a burst of light snow over the area that may offer some slight accumulations (a dusting to an inch the best bet at this point). This is currently not expected to be a major event and it appears to end by or before the Friday morning rush. The chance of light snow is about 40% for now. Confidence: Low-Medium

Friday and the weekend look to maintain our cold pattern with windy conditions setting in late Friday and Saturday (enhancing that wind chill again). Highs should be in the 30s (maybe upper 20s on Saturday) with lows in the teens and 20s. Cloudy skies are expected on Friday, variably cloudy Saturday, and maybe mostly sunny by Sunday with less wind. Confidence: Low-Medium

A band of flurries is moving through the Northwest suburbs and should make their way into the District in the next 30-60 minutes.

I have a question for you guys about the snow on Thursday/Friday. I'm leaving to go back to Mobile on Friday, and we're thinking about going through the mountains. We're going to leave fairly early Friday morning (not sure what time, but probably between 3-5 AM) for northern Alabama, where we're going to stop for the night. We're going Rte 29 to Charlottesville VA, to I-81 and we're going to take that down to Chattanooga, then we're going to take I-59 to Fort Payne, AL and stop for the night. Are you guys able to give me an exact weather forecast, mile by mile the whole trip down? Nah... :P Is that dusting-1" of snow just here, or will it be heavier/lighter the farther south in the mountains we go? Thanks!

I saw some flurries this morning.

Also, I put together a wildlife and weather 2009 Year In Review post.

@weatherdudeVA

While it may be snowing here when you leave, the snow should be ending or over in places to the southwest as you continue along your drive. Max snow you might encounter would be on the order of 1-3", but it will be light and powdery and already fallen for the most part. Not a big deal.

Thanks CWG! Glad it doesn't sound like it'll be too big of a problem (not only for us, but for anybody).

I am about to ask the oldest question that all kids in the DC region always ask: When is the next chance for a major snowstorm? I know you can't just give a definite answer, but during what time frame is there a chance for the next significant snowfall? Unfortunately, I was in Boston during that big blizzard a few weeks ago and came here during the aftermath.

weatherdude (and all)... traffic cams can be helpful before heading out to check on road conditions. For example, here's the Afton Mtn cam on I-64.

Just curious- I noticed the 'At a Glance' has %20 chance for snow Friday, but the NWS has %60 showing for Thursday and Friday. I have noticed the 'At a Glance' being a bit different than NWS' information on their page before, but thought the forecasts are from the same source. Is it just a matter of it not having been changed yet, on the 'At a Glance' box? Or does CWG make decisions that affect things such as the percentages posted in that section as well?

@snowlover2

The 20% it's showing is during the day Friday. The best chance of snow is Thursday night, but At a Glance doesn't give night percentages. This info is all direct from NWS.

@mmt

No indications for a major snowstorm in the next week or so-- and that's about as far out as we can assess this.

The preliminary extended forecast predicts dry weather for most of the eastern two-thirds of the U.S. for the next week or so.

It's getting quite a bit like last winter, with the difference being that we're in an El Nino rather than a La Nina.

The snow could be back here next month. Normally our biggest snowstorms happen as the Sun's path across the sky moves northward during mid-February. If the cold air hangs on, we could see another huge snow event around Valentine's Day or Presidents' Day. Wonder if the folks at AccuWeather are onto anything, long-range of this nature yet.

BTW, the Hagerstown Almanac is batting .500 right now with windy, colder & flurries predicted through the 7th, a HIT. They missed on a heavy snow event [a MISS] from the 1st to 3rd, but are predicting fair and very cold weather for the 8th and 9th. Looks like another HIT.

The National Weather Service seems somewhat bullish on the snow this Thursday night and Friday. When the scenario is just right - these Alberta Clipper type storms can dump a load on the region. I believe we have a 4-5 inch storm in 2004 that was an Alberta Clipper that did the same. Here is what the NWS Update said:

NEXT MAJOR WX MAKER WL BE AN ALBERTA CLIPPER THU EVE/FRI MRNG.
ATMOSPHERE CERTAINLY LOOK COLD...SO P-TYPE NOT A QUSTN...SHOULD BE
SNOW. SVRL INCHES WL BE PSBL...ALTHO IT IS TOO ERLY TO BE
DISCUSSING AMTS.

I think NWS is implying several inches possible in the mtns. Clippers tend to hit those hard, but not all of the precip makes it over those mtns.

Metro area may see an inch or 2 at the most.

Where's the Wednesday forecast? It's nearly noon and all I get is this "P.M. Update" from yesterday.

This has been one of the longest sustained spells of cold northwesterly wind I can remember.
