Alert: Snow Continues at Steady Clip

By Dan Stillman

Slightly higher accumulations; sleet and rain to mix in

An unofficial measurement of accumulated snow inside the Capital Beltway. Refresh page to update, or click here to enlarge.

Moderate to sometimes heavy snow has been falling across much of the DC metro area since late morning, and precipitation should continue for the next several hours. Some sleet has been mixing in with the snow to the south. Sleet and/or rain may begin mixing with snow in the metro area by mid to late afternoon, but uncertainty about the timing of the changeover is high.

The storm is unfolding mostly as forecast, though storm totals will likely be about 1-2" higher than in our accumulation map from this morning's post, which means more like 2-3" along I-95 (ligher amounts in DC itself), 3-5" in the NW suburbs (Fairfax/Montgomery counties), and 4-7" possible in parts of Loudoun and Frederick counties. That post also contains the storm timeline, school closing forecast, and frequently asked questions about the storm.

Thick fat flakes falling in Germantown. A solid 2" on ground

Posted by: Rob | January 17, 2008 12:52 PM | Report abuse

Snow very light and tapering off; freezing rain or sleet in Falls Church.

I'm supposed to drive to Capitol hill tongiht around rush hour. Any idea how bad the roads will be then?

Posted by: skwatcher | January 17, 2008 12:57 PM | Report abuse

Huge flakes suddenly giving way to snowdrizzle downtown. Is this the start of the changeover?

Posted by: jmbethesda | January 17, 2008 12:59 PM | Report abuse


It may very well be the start of the changeover. Over the next couple of hours -- at least, downtown -- snow is likely to mix with and then change to rain, perhaps with some sleet mixed in as well.

Whew! Snow wimp here reporting my safe arrival home in Germantown. My normal 15 minute commute took closer to 45 today on Clopper Road. Saw a couple of accidents and a Ride-On bus stuck and being pushed by the side of the road. Pretty slick conditions - streets not plowed at the moment, and poor visibility.

Snow changing over to sleet and rain in Reston. Very dangerous on the Dulles Toll Road. Reston Parkway slush covered.

Anyone have any insight on Saturday's storm?

Posted by: Snowlover | January 17, 2008 1:06 PM | Report abuse

Snowlover- on the way home on WTOP radio, they mentioned "light" snow on Sat.

Posted by: mark | January 17, 2008 1:08 PM | Report abuse

Thanks for the update on Dulles Toll road, Greg. Of course, snowlover that I am, there's none of it for a month. But when I have to travel tonight (to Las Vegas no less!) the heavens open up. My last plane trip out was in early December (the day we got the firat snowfall).

Hearing the sleety pings of discontent in Potomac.

Sleet here in Davidsonville. It was nice while it lasted.

Sleet mixed with snow, back to mostly sleet downtown.

Sidewalks becoming a slushy, icy mess. Commute home is going to be a blast.

Sleet now in Rosslyn

Posted by: Bikerjohn | January 17, 2008 1:31 PM | Report abuse

Snow changing to sleet/rain or letting up. Occasionally seems to go back to snow.

Jamie Y, sorry to hear about your snow absences, but given your track record this winter, I encourage you to plan a few more trips in the coming weeks!

Posted by: Parker | January 17, 2008 1:33 PM | Report abuse

Walked over to Chinatown for lunch... walk over was HEAVY snow, with slushy, slippery sidewalks.

Walk back was sleet mixed with a few big fat flakes of snow. Now back in the building and it's all sleet outside... pelting the windows.

This has been a fun day!

Light sleet and rain in Scott Circle.

Posted by: Nader | January 17, 2008 1:40 PM | Report abuse

Once it changes to rain/sleet is there any chance of it changing back to snow??

Posted by: marlee | January 17, 2008 1:42 PM | Report abuse

CapWx Team: Let us know when you put up a new post in the other post's comments, since people are still carrying on in the old post.

On to the weather... I've been watching WeatherBug, and temps have actually been falling at the sites around Bowie. Now around 29-31. Maybe no changeover to rain...?

Posted by: jtf | January 17, 2008 1:42 PM | Report abuse

It's sleet/ice/something not snow in Falls Church. On my way back from lunch, the main roods (7 and 29) were ok, but the side streets were really becoming a mess.

I'm hoping for rain soon, so the drive home isn't absolutely horrendous.

Posted by: doug | January 17, 2008 1:42 PM | Report abuse

Sleet- Bethesda

Posted by: Peter | January 17, 2008 1:43 PM | Report abuse

Guess I won't take the toll road home, but I wonder how the side streets are as an alternative to get there.

The past half hour's sleet in Ballston has given way to very light rain mixed with a very few small flakes.

roads a mess in Rosslyn, no clean up whatsoever so far. snow and sleet mixed, both heavy, still falling. Anyone have a report on Alexandria (Old Town and west out Duke) roads?

definite rain mixing downtown, also noticing temp rise at dca

Posted by: grant | January 17, 2008 1:48 PM | Report abuse

Wow, cold Kegger beer in the parking lot sure tastes good with golf ball sized flakes....

Looks like we had a a temporary changover to sleet but flakes are coming back down...

Can't wait for Saturday.

Ashburn, VA

Just shoveled the driveway -- about three inches. Sleet picked up some when I was out there. Gotta love working from home. Parker, my next trip out is the 29th through the 31st, so plan accordingly :)

Sleet and 31F here in Arnold...

Just started sleeting in Germantown

Posted by: mark | January 17, 2008 1:51 PM | Report abuse

Yup. Sleet now in Germantown. Why does rader loop still show snow/mix line well south and east of DC? Is that based on ground truth or estimates based on temperature?

Posted by: Rob | January 17, 2008 1:52 PM | Report abuse

It actually just shifted to the south and east. Was previously right over top of DC.

Still snowing in Darnestown; temp is about 32.5. Haven't measured the snow, but it was slick enough to prevent a truck from making it up our driveway.

Posted by: Welmoed | January 17, 2008 1:53 PM | Report abuse

All snow in Hburg, 5.5-6 inches on the ground. Definitely more than expected.

Posted by: Russ | January 17, 2008 1:54 PM | Report abuse

Sleet and light snow hanging on here at Fort Belvoir. Think we got about 2-3 inches since mid-morning, with the current temp coming in around 32 degrees. I didn't expect the frozen stuff to hang on even THIS long, but everyting on post is snow-covered and looks great...

Posted by: VAStateOfMind | January 17, 2008 1:55 PM | Report abuse

Four and a half inches, 29 degrees and still some light sleet and snow falling.

The GFS has finally climbed on the bandwagon for Sat. It now gives us 1-3" Sat. pm while the NAM gives us 4-8" Sat. pm!

Posted by: Augusta Jim | January 17, 2008 1:56 PM | Report abuse

sleeted/rained for a bit about an hour ago, but it changed back to big ole flakes and now, smaller flakes but it's coming straight down. Four plus inches in New Baltimore

Posted by: weathergrrl | January 17, 2008 1:56 PM | Report abuse

Storms like this make it hard to determine where the snow/ice/rain lines are. As we saw today, the temp can be above 32 on our thermostats and we can get plenty of snow. The radar is showing where the concentrated sleet and ice are falling but it doesnt mean there isnt sleet falling elsewhere.

Posted by: CMc62480 | January 17, 2008 2:02 PM | Report abuse

The changover from snow to rain will happen because the temperature higher up in the atmosphere is warming. When it changes to rain and your temps on the ground are still below freezing you will get freezing rain.

Granny and my Dog Rickett are going to have to stay tented in the parking lot until Sunday!

I might have to buy another keg for rickett and I.

Yes, I know that, but I was talking about a changeover to plain rain.

In fact, I think it may be raining freezily here at the moment. Temps still below freezing... yuck.

Still snowing in southern LoCo per Mrs. ARC...4 inches on the deck and Dog ARC (whom some of you may remember from some pictures last winter when we still could post them...GUYS!!! Lets get that back up!) is loving every minute...of course Baby ARC just naps the day at 21st and E it seems to be light sleet and rain. Id much rather stand at a bus stop in the snow than in the snizzle...

It rained for a half-hour or so here in Fairfax (66/Nutley), but it's now snowing again, pretty hard. PM rush hour could be unattractive . . . .

Any backfilling on the west side of this storm (Central Loudoun) possible? Looks like west side drying with a push of cold dry air...but front end strengthening on coast...

I really hope the roads are safe for the school children heading home this afternoon. I haven't been on the roads, but looking out my window at work, the pavement doesn't look so good. How are the side roads in Arlington and Alexandria at this time?

up to 3 inches here. Snowflakes have gone from big and fat to itty bitty....had to double check that it wasn't sleet. (Not yet anyway)

Looking at the radar, a large pocket of light rain has pushed its way up into the downtown area, could be it for the snow here. Except that, just as I typed that, it changed back to tiny flakes. Guess we're still on the border.
