FORECAST IN DETAIL


Radar: Latest regional radar shows movement of precipitation over past three hours. Powered by HAMweather. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.

A classic East Coast storm will move up the coast today, wrapping in moisture and cold air, and producing a wintry mess of precipitation. Rain or a rain/snow mix this morning is likely to gradually transition to wet snow this afternoon that could be moderate to heavy at times. One to several inches are possible, with most accumulation on grassy areas. However, as snowfall rates pick up and darkness settles, slick roads will become a possibility. The snow ends before midnight. Sunshine returns Sunday, but it will be on the brisk side.

ACCUMULATION MAP AND TIMELINE

IMPACT FORECASTS

STORM FAQ

How confident are you in your forecast? We're confident that we'll have a sloppy mix of precipitation and that it will change to snow. The big questions are will it snow hard enough and will temperatures fall quickly for snow to accumulate.

Keep reading for more storm FAQs. Just found us? We're here 24/7/365 -- rain, snow or shine. Visit us at washingtonpost.com/capitalweathergang.

How much snow will I get at my house? Check out our accumulation map. Generally, we're expecting 2-4" in the north and west suburbs, with 1-3" in the District and south and east where temperatures will be marginal for snow accumulation.

Could the storm bring more snow than expected? Yes. In order for this happen, we will need heavy precipitation to develop. That will serve to cool the air and high snowfall rates might overcome the effect of the warm ground. There's a 1 in 3 chance of 4"+ in a few spots.

Could it fizzle out and leave us wet? Yes. A significant impediment for snow accumulation is the relatively warm air that will be in place when the precipitation first arrives (in the 40s in some spots). It will take some time for the precipitation to cool the air and for precipitation to change from a rain (or a rain/snow mix) to snow. In the past, some of our biggest underperforming snow events have occurred when the changeover to snow took longer than expected. And, the warm ground could limit accumulations.

Will we see any of the dreaded wintry mix? There may be a period of a rain/snow mix and even some sleet as precipitation transitions to snow, but no ice will accumulate given warm ground temperatures.

When will this storm start? Early Saturday morning between 3 and 7 a.m. in most spots.

When will the heaviest snow fall? Most likely from mid-afternoon to early evening.

Will the snow stick? Probably, but it will take a while. Colder locations to the north and west will first see the snow sticking -- possibly mid-afternoon. In the milder locations in town and south and east, sticking may not happen until after dark.

What will conditions be like after the storm? It will drop below freezing Saturday night, so watch out for icy patches Sunday morning. Sunday and Monday will both be sunny, with highs 40-45. Any snow that falls should pretty quickly melt.

What are other outlets forecast?

*National Weather Service: 1-3", except 2-4" N&W
*NBC4: "Several inches of wet snow possible"
*ABC7: 1-3"
*WUSA-TV9: 1-3" in metro area
*Fox5: 1-3"
*AccuWeather: 1-3"

light rain, 35.8 in gaithersburg currently

Even with the 2-4 inches, are the roads expecting to be still be okay for driving? i.e Most of it won't stick since they will be so warm so it won't feel like a true 2-4 inches. Any chance it doesn't get cold enough and we get a rain-snow mix for most of the day, cutting down on snow amounts?

Posted by: derrickd | December 5, 2009 7:07 AM | Report abuse

Good morning CWG and community. I have to echo SkywalkerSS from last night's discussion. Even though the forecast is for a period of rain (for most of the area) prior to any flakes, "bust" posts will probably start flowing in around noon.

Q: Is the cooling supposed to start once the heavier snow starts falling, or will heavier rains facilitate this "drag down" of colder air? My guess is it requires snow, but just curious.

Observation: I just let the dog out and noticed a few flakes among the drizzle (Northern Montgomery Co.- Laytonsville area) .... probably won't last all day, but WHAHOO... the kid in me just perked up!

Thanks for the fantastic write-up of today's forecast. It's very concise and easy to read.

@dprats

Rain falling will help gradually cool the air

@derrickd

Roads show be fine for most of the day. Late this afternoon and after dark, as temperatures fall and snow picks up, some roads could turn slick, especially N&W of town.

i live in resiterstown MD and the precip changed to all snow about 30 minutes ago. only a small amount is sticking. i think that the reason for the early change over was because the storm is stronger then forecasted, and it pulled the cold air in faster then expected

The timeline was right on for the beginning of this storm, but we had a about 30 seconds of sleet before the flakes started swirling down. Almost an inch already in Fauquier.

We finally have a storm that seems like it will get the change over in the "earlier" portion of our expected timeline. Maybe that will help to reduce some of the calls for "Bust" as this day goes on.

Am jealous of Leesburg and all the snow they seem to have on the ground already.

Am looking forward to seeing the flakes myself.

Yellow, it's snowing while temps are mostly still in the mid-30s due to the fact that the layer of the atmosphere that's above the freezing point is very shallow right now. Simply, the snowflakes dont have time to melt before they reach ground level.
