PM Update: Snow to wind down but cold

By Jason Samenow

The snow got off to fast and furious start but is now dying a slow death. Much more spotty and less intense than earlier, the snow will continue to dissipate into the evening although a more intense band or two could still pass through until 6 or 7 p.m.. Temperatures are well below freezing so snow that melted during the day may re-freeze as daylight ceases. Please exercise caution commuting. Much quieter weather arrives tomorrow.

Through Tonight: Patchy light snow and flurries continue intermittently through early evening with some areas seeing little additional snow. By 7 p.m., the snow should be over pretty much everywhere. Skies then slowly clear with lows ranging from the high teens in the colder suburbs to the low-to-mid 20s downtown.

Tomorrow (Friday): The return of at least partial sunshine means it's not as cold as today, but our light snow cover will hold temperatures down a bit. On the other hand, the sun will pretty easily melt away snow cover in areas facing south. Highs range from 30-35. With winds blowing from the northwest at 10 mph, there will be no mistaking the season.

Snow totals: Generally, 1-2" of snow fell across the region. Also, the National Weather Service has a website summarizing totals, but it tends to be a few hours behind. Please comment with your totals...

Weekend snow threat: The latest computer model guidance suggests the odds of snow Saturday night into Sunday have increased. Capital Weather Gang's winter weather expert, Wes Junker, will share his insights on this situation in a post probably around 7 p.m. or so.

HPC still a bit cautious but starting to "honk" a little for the weekend. QPF map not bad...

Model watchers - Is the Sunday snow threat dizzying or what? After a couple days of mixed signals from the models, yesterday evening's and the overnight GFS had precip way out to sea. This morning's GFS and Euro showed accumulating snow all the way back west to the metro area. 18z NAM is further out to sea than 12z NAM. Next up is 18z GFS. Which way and how far will the storm wobble next? Gotta love winter. -Dan, CWG

What are the odds that schools will be closed tomorrow?

Safe drive home everyone!

Yeah that NAM model is awful for snow lovers. Why such fluctuation?

With only an inch or so in the general area, it would be a travesty to keep kids home tomorrow. If only because we should be able to clean up and have safe roads/sidewalks/parking lots 12 hours after one inch.

But as for the storm on Sunday, when you say we will get hit - what do you mean by hit? Three inches? Six inches? Feet?

My personal opinion, there may be delayed openings because of concerns for buses driving on frozen/refrozen roads. It has nothing to do with how much snow there is.

Snow picked up again south of Hamilton VA. About 1 3/4 in. Country dirt roads are slick and a mess.

Bastardi's latest post...well a portion of it. As someone looking for a good snowstorm, I sure hope he's right!

Assuming, of course, your feast is one that has snow.

Again, from DC to NYC, heaviest amounts will be southeast of you. However, I do believe this will have increasing amounts northeast, but in the I-95 lingo, it's Boston and Providence that have the best chance of getting a storm that has news crews on the loose.

However, if a shift in my ideas is going to occur, and those that follow me know I don't like running with every model, it would be to push snow farther west. The coastal areas would still likely get the most, but the storm could be a major one, even back to DC, and of course that would include PHL, BWI and NYC. Worst case would not only close the Massachusetts and Connecticut turnpikes, but the Jersey, too. That is on the table.

very interesting

CWG any thoughts on Tuesday "storm"?
ABC 7 has a 80% chance of light snow with 2-3 inches possible

Folks-- we're going to have a full post on the weekend threat this evening. Hang tight...

1.75 inches in New Baltimore. Bet on a delay, if not cancellation for school in Fauquier.

I convinced my parents to let me take the Prius out for winter driving practice. (I'd never really driven on snow before.) I practiced different braking and turning strategies, and found (naturally) that the best braking strategy on anti-lock brakes is to go slowly and smoothly, rather than slamming on them (which doesn't slow the car much at all). Good to know for that day when I actually have to leave our street in snowy conditions.

booo 18z GFS & NAM have gone away from their earlier snowier solutions for this weekend. Which brings up a good question for CWS? Are the 18Z runs of the GFS and NAM not as accurate as the 00Z & 12Z runs because they don’t take into account weather balloon data? (For those of you that don’t know, weather balloons go up twice a day 12z (7am) & 00Z (7pm est.) to collect data which is then incorporated into the models at those times.)

KBurchfiel, I applaud you for being smart enough to go out and practice so you know how to drive in the snow.

go to a shopping center parking lot when empty.

Posted by: walter-in-fallschurch | December 16, 2010 8:57 PM | Report abuse

Second going to an empty shopping center lot. While you're there, try out the stuff you shouldn't do - i.e., use some speed and slam on the brakes. Experience a spin out and get familiar with how to react.

Being a part of "Hypersonic Weight Loss" has put me back in touch with the fun-loving, exotic woman within.

Posted by: felixlium | December 17, 2010 2:11 AM | Report abuse

"Hypersonic Weight Loss" taught me how to creatively express that which only a woman can do and feel. I did this for me. My goal was to get shaped, toned and lose weight.
