Ready or not, winter’s returning! Let’s chat. Two potential periods of wintry precipitation coming through the region tomorrow night through perhaps Wednesday. Parts of the forecast have come into better focus—including higher probability of snowfall accumulation north & west of the city—while significant questions still remain:

Ahead of the the first wave of precipitation tomorrow night, our PM Update has cooler but tolerable weather for Monday:

Sunday evening update: Natonal Weather Service map shows I-81 corridor most likely to see significant (4"+) snow between Monday night and Wed. While some wet snow a good bet closer to I-95, big totals are more iffy but situation merits watching. More info:

HRRR simulated radar for Feb 17, 2018
We're trying to find sunshine but it's just so very cloudy for now...

PM Update: Cold tonight with clouds on the increase by daybreak. Rain moves in late on Monday

Tranquil weather continues through tonight before we enter into an extended stormy pattern starting tomorrow night.

Key time windows for possible snow this week are during the day on Tuesday, and then early Wednesday morning. Another brutally tough forecast...

Parts of the forecast have come into better focus, while significant questions still remain.

D.C.-area forecast: Sunny and milder today; rain and snow likely Monday night into Tuesday

Some accumulation possible by Tuesday morning, but how much would stick to the roads versus grass is still in question.

Snow potential index: 4/10 (↑) An inch or more Monday night-Tuesday is doable but not definite, and how much would stick to the roads vs grass is still in question, as we struggle with another tough forecast.

Sunday Digit: 8/10 - Maybe I'm just tired of the teasing snowstorms, but I'm ready for spring, and a sunny day well into the 50s is just what the Dr. ordered. Brian, CWG

UPDATE: We're releasing our first estimate (likely to be refined on Sunday and possibly Monday) of snowfall potential Monday night & Tuesday in the DMV. More info:

P.M. Update: Showers will end early in the evening. Spectacular weather ahead for Sunday.

Showers dissipate this evening, setting the stage for some truly ideal weather on Sunday

A winter storm is coming together for Monday night into Tuesday. There are still a lot of details to work out, but snow odds are growing for parts of the region. A moderate snowfall is possible in spots.


D.C.-area forecast: Some wintry mix possible today, a superb Sunday, and watching a winter storm risk

Today's weather is mostly inconsequential. Whatever is coming Tuesday and Wednesday remains complicated.

Saturday's digit: 4/10 - I’m ready for warmth. Instead, it’s more clouds and some chilly raindrops — perhaps a little mixed precip as well.

Snow potential index 3/10 (→) Tue/Wed details aren’t really any clearer than they have been. Still very much wait and watch.

PM Update: Light rain may mix with sleet and snow Saturday, then it’s pretty pleasant for Sunday

It's a cold one tonight. We get a little bit of everything this weekend.

On Saturday, don't be shocked to see a bit of light wintry mix (snow, sleet, and/or rain) in the D.C. area between mid-morning & early afternoon. Temps will be above 32, so minimal impact. In any event, this is not an all-day thing and precip will be spotty.

In our colder areas along & W of Interstate 81, where it comes in early Sat AM, it could be a little slick b/c temps will be near 32. Winter weather advisory is in effect for these western areas Saturday morning and afternoon.

Strong signal for Mid-Atlantic storminess next Tuesday and Wednesday, but how big a deal this will be depends so much on the specifics, which are fuzzy right now.

If you live in the northern and western parts of the region, you have the best chance to see significant snowfall, but rain could prevail if the storm takes more of a northern track.

We will keep providing detailed updates on this each day as long as it poses a threat.

Washington's far northern and western suburbs have the best chance of significant snow but, even there, the forecast is uncertain.

What a shot! This is our #cwgpicoftheweek

It's the time of year that thunderstorms can start popping in the Pacific Northwest.

Programming note (Friday morning): We'll have an update on next week winter storm possibility midday or early afternoon. Lots of data to sift through!
