Alert: Accumulation Coming to an End

By Dan Stillman

A basketball left on a playground in Northern Virginia from our last spell of warm weather is covered by 4 inches of snow. By Capital Weather Gang photographer Kevin Ambrose.

Within the metro area, most areas have seen snow mix with or change to sleet during the early afternoon. The changeover to sleet and possibly rain will likely contiue to progress from southeast to northwest. To the north and west, places like northwestern Mongtomery County and Loudoun County may hang onto a higher proportion of snow a while longer. But temperatures at or above freezing -- even Dulles was up to 34 degrees as of 2 p.m. -- should minimize any additional accumulation in the immediate metro area. Nevertheless, continuing precipitation and slick spots may cause travel troubles into the evening. Precipitation should end from southwest to northeast after about 7 p.m.

Please report accumulation measurements using the comments link below. Some unofficial storm reports can found here. And check out Capital Weather Gang photographer Ian Livingston's DC snow pictures taken earlier today.

We're still watching another potential snow-producing storm for late Saturday, but it remains uncertain whether it will track close enough to the coast to be significant. More details on that this evening or early tomorrow. Stay tuned for more updates on today's weather later this afternoon or evening as warranted.

First! Mostly rain here in Ballston. Little snow mixed in. Bunch of slush overall.

After a brief period of sleet here in Germantown, it has gone back to snow for now.

BTW, the Sterling afternoon forecast discussion says this about Saturday:

Absolutely gorgeous in Mclean, to the point where I found it hard to concentrate in school. Currently 32 degrees outside, with 2.25 inches of snow and a quarter inch of sleet covering the grass, roads and everything in between. Precip seems to have eased off around here for the time being.

Huge beautiful burst of fat flaked snow again at the Government Center in fairfax. In the span of 2 minutes, everything has been covered again.

Interesting... if I'm reading this correctly, the NAM keeps us below freezing up 'til midnight.

Am I looking at this wrong? It also seems to show rather extensive precip in the 6 p.m. to 12 a.m. time span.

So what are my chances of a late start or school cancellation in Arlington tomorrow? I really wouldn't mind a 4-day weekend!

For Saturday's potential storm, I'm not quite sure what Sterling is basing their "changeover to rain" mentality on, unless they are talking about the Eastern Shore or Hampton Roads. The rain/snow line looks like it may stay pretty far S&E.

Posted by: jtf | January 17, 2008 2:59 PM | Report abuse

Expat teacher: Temperatures might not drop below freezing tonight for some areas, so I would expect school.

Has been sleet here near Union Station for the past hour, but has now gone back to snow with a little bit of sleet mixed in.

Is it possible the storm is pulling in cold air again at the upper levels?

Big flakes coming down again in Rosslyn. Perhaps the development to the southwest will continue as snow in the metro area??

On radar there appears to be another band of sleet moving north of Fredericksburg. This could cut off the snow in an hour, as another batch of sleet moves through.

Back to huge flakes at McPhereson Square - moderate to heavy snowfall.

Earlier sleet accumulated a bit on roads/driveways, new snow is sticking to the sleet better than wet ground.. turning a bit white on pavement.

Snowing again in east Silver Spring (Sligo Ave area). Good size flakes falling steady, and this just after a set of three county snow plows made three passess on Sligo between Georgia and Piney Branch.

Posted by: TDowdy13 | January 17, 2008 3:12 PM | Report abuse

Tysons had 2.75 inches at 12:55. It was sleeting for a little while then, but we've had snow off and on since then. Until about five minutes ago, it was big flakes, but is now much smaller. I can't tell if it is snow or rain -- not making enough noise for sleet.

Posted by: WFY | January 17, 2008 3:16 PM | Report abuse

We'll continue to go back and forth between snow and sleet especially north and west, along with some rain especially south and east. Most appreciable accumulation should be wrapping up now, but I'd estimate parts of Montgomery, Fairfax and Loudoun counties could see about a half-inch more on top of current totals.

Posted by: marlee | January 17, 2008 3:20 PM | Report abuse

It was sleeting at a nice clip when school let out around 2 this afternoon. Then it changed to snow briefly, then back to sleet. I was just outside taking pictures when the BIGGEST, HEAVIEST snowflakes I've ever seen started falling. Lasted about 5-7 minutes. Raised our accumulation by about 1/4". In Lake Ridge, Virginia we now have about 3.5-3.75" of snow. The roads are a MESS though! Schools didn't let out early "to give the road crews a chance to clear the roads." Looks like they used that extra time to go to 7-11 for coffee and donuts (LOL). There is about 2" of slush on the main roads, and about 3" of snow/slush on the side streets.

Hopefully the road crews will stay at 7-11 to give PWC Schools enough time to cancel school tomorrow, then they can clean the streets all they want. :)

...and back to the gigantic snowflakes!

What is making these flakes SO BIG?

Is it the fact that they have a high water content and they're sticking together, or is it something else?

Just went outside - about 4 inches in Potomac, still snowing, although more lightly.

Thanks for all the weather reports. For those stuck in the offices without windows, it's great to get a feel for what's happening outside.

I also hope we are getting some new visitors as well. Pull up a chair and stay for a while. Over the next few says we will of course recap today's weather, and look ahead to what may be in store for Saturday (and beyond!). You now know where to find us.

Its snowing snowballs at the Government Center in central Fairfax. When they hit the ground, they make a 3" pancake of coverage. My assumption is that its a rare mix of high precip, wet sticky snow, and no wind to blow them apart. Whatever their reason for existance, its a treat to experience.

So, like an idiot, I rode the Vespa in from Adams Morgan to Chinatown. I figured if the roads were too bad, I'd just lock it up, and take Metro home. I decided to ride home and there is a NOTICABLE difference on the roads in Adams Morgan vs. downtown. I little slush dowtown, with enough wet pavement to make it safely, but once I got up by Dupont, and continued up the hill on Connecticut avenue, it became fully covered in slush. Amazing how this storm had such a different impact on different places only a few miles apart. I'm home now, safe and sound...

PWCounty didn't let out early...and the roads were still a mess on the way home. The extra time for the roads to get treated certainly wasn't particularly helpful. I almost slid into a big intersection even in 4wheel drive. A big trash truck had straddled the median just in front of me. Be really careful and slow down even if it appears to be just "slush".

Posted by: missy | January 17, 2008 4:27 PM | Report abuse

Walter: Steve's normal afternoon shift is coming up, but for most of the area, once you go to rain, you are going to stay. However, for some western and northern areas, you may tetter between rain and snow for a while like your neighbors to the south and east did before going totally over to rain.

Posted by: Jamie Jones, Capital Weather Gang | January 17, 2008 4:34 PM | Report abuse

Hey all you 4-wheel drive folks out there...there is no such thing as 4-wheel STOP!! Please slow down and don't assume that big truck of yours can stop any faster than my front-wheel drive sedan, 'cause it can't. 4-wheel drive is only useful while you're actually moving, not when you're trying to stop.

Just gorgeous down here. We never really changed over down here. Sure, there was a little freezing drizzle towards the end, but the major precip with this event was almost entirely snow. Looks like Blacksburg ended up with 5-6", more like 4-5" here at my office in Christiansburg. Roads were treacherous in the morning, but are basically cleared now - our road people work fast.

Here are some nice pics from the Roanoke Times:

I'm hoping a good bit of the snow survives tomorrow's 40s, so I can have some weekend fun with the snowpack ;-). Oh, and maybe it'll be refreshed a bit on Saturday! :)

Merging onto the Toll Road now. Much more snow here in the Tysons area than in Foggy B. Its not too bad in terms of traffic. GPS has me at 51 mph...(I'm on a bus!). It does look much slower heading toward the Beltway and 66. Much slower.

Trends on models for the weekend event are seemingly bad ones this afternoon if you're looking for a lot more snow.. still time to change that though.

All rain here in Merrifield now - it's a light rain, except that the drops are BIG, just like the flakes earlier.

Even main roads were a bit slushy on the drive home, & side roads were covered in smush. Any freeze overnight, and tomorrow's a.m. commute is gonna be a bear.

All wintry precip has stopped in Lake Ridge VA. We picked up about 3.75" of snow before that stupid RAIN knocked it down to 2". It's pouring regular ole' boring rain right now.

Now if only it would FREEZE so they could call school off tonight rather than 530 AM so I wouldn't have to set my alarms. HA!

Actually, after seeing the roads over here on the East side of PWC, I couldn't begin to imagine what the west side looks like. Whenever the weather poops out over here, we always look at the Western half of PWC (Haymarket, Nokesville, etc) as our shining beacon of light for any hope of a snow day. LOL! Hopefully they did a lot better than we did!

Posted by: weatherdudeVA | January 17, 2008 5:20 PM | Report abuse

I just don't see much of a chance for a freeze overnight. The NAM has consistently predicted an overnight warm-up, meaning temps probably won't get much cooler than they are now.

Shame that a 3-inch storm wouldn't cause any delays or cancellations for Fairfax County Public Schools--even by our standards.

3.75" on my back deck in Fairfax City at about 3:30, before the rain started in earnest. We had a decent accumulation on the ground when I started shoveling the top of the driveway, but by the time I got past the first car, wet sticky snow had transformed into thick white concrete mix! Oy, I'm gonna feel this tomorrow...
