Hallelujah! The wind is gone for at least a couple of days. And, after a cloudy, coolish day today - what a New Year's Eve and start to the weekend! I would not be surprised at all to see us make a run at 60 on New Year's Day. But a cold front comes to spoil the fun late Saturday into Sunday promising some light rain showers. I hope it's enough to wash away all those horrific salt drifts!

Snow Potential Index: 0 (→) - Sunday brings a good chance of rain but only an errant flake of snow is possible Sunday night.

Today (Thursday): Clouds are abundant as a rain system in the Ohio River Valley is breathing its last gasp. There is a 10% chance for a few raindrops around midday but not the umbrella toting variety. And, are you ready for this forecast term? Calm winds! Despite the clouds, highs should still reach the mid-to-upper 40s. Confidence: Medium-High

Tonight: This is a relatively pleasant night to be out and about with readings holding in the lower 40s downtown and upper 30s burbs. Winds still calm are a plus under mostly cloudy skies. Early morning lows fall to the upper 20s to lower 30s. Confidence: High

Keep reading for the forecast through Monday....

New Year's Eve (Friday): The peaceful weather gets even better. Winds are but a whisper from the south and skies have plenty of breaks for the sun to shine down. Highs push steadily upward with well above normal low-to-mid 50s. Resist the urge to go sunbathing! Confidence: Medium-High

Tomorrow Night: The mild conditions linger throughout the evening with readings well into the 40s and only light winds from the south. Clouds should slowly increase overnight. Lows only bottom out in the mid-30s to lower 40s. Confidence: Medium-High


New Year's Day (Saturday) has all the makings of an outdoor kind of day if the cold front to the west holds off like I think. Mostly cloudy skies do little to impede the warm-up. Winds begin to finally pick up from the south reaching 10-15 mph by afternoon. While a light shower is possible by late day, the best chance is overnight when the probability goes up to 40%. Not a bad idea to have an umbrella at the ready. Highs should reach the mid-to-upper 50s. Overnight, winds shift to come from the west at 5-15 mph with lows in the mid-to-upper 40s. Confidence: Low-Medium

Sunday is the tricky day weather-wise. Clouds in abundance are the best bet. Showers are a pretty good hunch at 60% odds though more likely late in the day rather than early. Temperatures don't move much given the breeze from the northwest and peak midday in the upper 40s to lower 50s. The interesting thing is that the latest models show enough development along the front to keep moisture in the area until the real cold air arrives in the evening. This raises the possibility of a few wet flakes of snow but accumulation would be highly unlikely. Overnight lows slip to the upper 20s to lower 30s. Confidence: Low

Monday is back to sunny, seasonable conditions. Winds from the west are 5 to 15 mph but could gust to 25 mph. Highs should be near average in the low-to-mid 40s. Confidence: Medium

I want snow.

I'm wondering if it's worth trying to scare up some crew for a mid-day Potomac River sail on the 1st. I've done that in years past, and it's great fun if you keep it short. Those winters were warmer overall, though, with no ice on Hunting Creek or the river itself. I'm worried that the water will be so cold that even steady sunshine & temps near 60 won't keep us warm enough.

Thank goodness we didn't get any snow! I for one do not need any more than a dusting nor do I want New York's problems-again. Bring on the 50's!

Gang, thinking about taking the kids tubing at Ski Liberty tomorrow - will it be as nice up there as it is here? Thanks....

@dannythe357 There is nothing of significance on the models right now showing any notable snow threats. There is a good piece of energy around the 8th/9th that will need to be watched though.

@rcky-mtn-roots It should get up near 50 F tomorrow so have fun!

I've heard rumors about that active southerly storm track possibly cranking up again in the next few weeks. If the cold air is in place, we could get hammered!

However, you did ask if it would be anytime soon, and the answer to that may be no. I say that because usually the folks over at start talking about *possible* storms almost two weeks out, and I haven't seen anything about an east coast snow on their website, but I'm sure that the good old CWG will keep you posted!

I reccomend that you don't worry about this, because, chances are that after last winter, we might get nada in terms of snow this winter. Just look forward to Spring, which starts in a mere 3 months.

P.S. The National Weather Service is predicting below average precip. for the next two weeks.

Hey guys... Is it too early to ask: What do you think the weather will be like for the 4:15 Redskins game Sunday?

Posted by: smill30 | December 30, 2010 10:45 AM | Report abuse

Looks like a stretch of generally boring weather to start 2011...though there could be the outside chance of a thunderstorm.

Any idea how Saturday and Sunday are shaping up in Shenandoah, specifically the Thornton Gap area? I am thinking of going out there for the weekend, but am worried about rain on those days. Thanks!

There's a chance of showers Saturday afternoon, better chance Saturday night, and slight chance Sunday.

I know CWG doesnt discuss storms more than 7 days out but the rest of the internet is ablaze about the Jan 8 thru 15 timeframe. Apparrntly there are 2 possible snow storms in that time for the east.

I know to take it with a grain of salt BUT this past weekends blizzard for PA on up north was being talked about 2 weeks out as well and it did happen. I love you guys here at CWG but yours is the only wx blog that wont discuss potential storms a week+ out :(

And please dont say because of the low uncertainty because other wx blogs have been seeing and calling these storms out 2 weeks or more in advance. Not asking for a prediction, just some discussion on possibilities and likelyhood!?!
