Alert: Advisory Upgraded to Ice Storm Warning
Warning in effect area-wide until 7am Wednesday morning
From the National Weather Service:
"AN ICE STORM WARNING MEANS SEVERE WINTER WEATHER CONDITIONS ARE EXPECTED OR OCCURRING. SIGNIFICANT AMOUNTS OF ICE ACCUMULATIONS WILL MAKE TRAVEL EXTREMELY DANGEROUS. TRAVEL IS STRONGLY DISCOURAGED. IF YOU MUST TRAVEL...KEEP AN EXTRA FLASHLIGHT ... FOOD ... AND WATER IN YOUR VEHICLE IN CASE OF AN EMERGENCY. ICE ACCUMULATIONS MAY LEAD TO SNAPPED POWER LINES AND FALLING TREE BRANCHES THAT ADD TO THE DANGER."
Light freezing rain continues to fall throughout the metro area. Temperatures remain in the upper 20s to near 30 degrees. Due to a stubborn and persistent north wind, temperatures may remain subfreezing through the early morning hours, especially in the north and west suburbs. A similar situation occurred last year on the eve of Valentine's Day. By mid-morning tomorrow, just about everyone should be above freezing and plain old rain will be falling. Tomorrow evening though, a coastal storm may develop, causing the rain to change over to snow. More details on that scenario later this evening.
There have been widespread reports of treacherous sidewalks and road surface conditions. Please be very careful walking, and driving especially on ramps, overpasses, bridges and untreated roads.
Next update, including Schoolcast, at approximately 11 p.m.

This is AWESOME news for us students. YAY. I will bet you all the money in the world and a camper that everyone in that warning will be closed tomorrow provided the temps don't creep above freezing.
I just hope the power doesn't go out. It has blipped a few times. I know that everything is covered in a sheet of ice in Lake Ridge and the sirens haven't stopped running since the freezing rain started 4 hours ago...

Yeah, its slick out there. I just slipped on my deck in Spotsy.
Be careful folks.
Posted by: CfromVA | February 12, 2008 7:15 PM
The sidewalk is solid ice, the foot bridges are solid ice, cars are encased as well as trees and polls. The grass is frozen solid except for the tippy tops of the blades, one of the strangest things I've ever seen. Parking lot is just wet that I could tell, even next to the curbs it was just wet. Strange.
Posted by: weatherdudeVA | February 12, 2008 7:26 PM
Just drove through NW DC and Bethesda. Roads mostly just wet in the District. Main roads not too bad in Bethesda, but side roads a bit icy, and parking areas and sidewalks very icy.

Everyone "think snow", lets hope 00z models are our friends for tomorrow night.
Costal Storms often are interesting and difficult to forecast. Occasionaly, they bring us suprises both good and bad.
Over the past 3-4 days. GFS continues to hold a coastal development tomorrow. 18z run is now showing higher confidence in a snow event tomorrow night.
Posted by: CfromVA | February 12, 2008 7:30 PM
wow...stay off the roads. Multiple accidents/roads closed here around Manassas.

Sorry.
Posted by: Peter | February 12, 2008 7:44 PM
Just drove home (downtown DC) from Rockville. Traffic is in general very very bad. Saw four spinouts on the GW parkway between the beltway and Key Bridge. Nearly spun out myself on the Whitehurst Freeway. It's not slippery all over, but there are patches that can come up on you without warning. Also saw several pedestrians fall while I was looking for a place to park. Be careful!

Posted by: d | February 12, 2008 7:50 PM
ccwx...Maybe their underdoing it.....:)
Guys tonight might be the "calm" of tomorow night.
Funny, I am actually getting my hopes up for tomorrow. Especially when I heard some Cap members talking about possible accumulation. I have a feeling they are remaining conservative at this point because its a complicated event just now developing. I am sure there may be a couple scenerios begining to develop on possible tracks and devlopment of the low. I bet one of them brings us a big snow storm.
Posted by: CfromVA | February 12, 2008 7:50 PM
If MoCo doesn't delay/close, I swear to you... it's gonna be hell on my bus tomorrow.
Posted by: Peter | February 12, 2008 7:52 PM
I'm still thinking that there will be school tomorrow at least in areas near D.C. You never know!
Well, I hope that I know that we won't have school, but I might jinx it if I say that we won't so we will. =pp
What are the possibilities of a major (1/4) amount of ice actually accumulating?
Posted by: Period | February 12, 2008 7:52 PM
ARGH. I am supposed to leave for the Daytona 500 tomorrow moning, and am driving down. (easier to transport the, er, beverages that way :).
Any idea what time it might be safe to consider heading out? I had planned on leaving at 7...but it looks like there might still be ice at that point.
Posted by: Kim in Manassas | February 12, 2008 7:55 PM
Some weather-geekery: Classic cold-air damming has taken shape across the region:
http://www.rap.ucar.edu/weather/surface/sfc_bwi.gif
Note the northerly flow that has developed over the last few hours across the area. That will help reinforce the subfreezing air during the next few hours, but >32F air is making inroads near the Bay and on the eastern shore. A lot easier to analyze than forecast!
Posted by: Ryan | February 12, 2008 7:56 PM
Just walked...slid..out onto the deck. Trees are covered. The car that had been thawed off the roof of the Vienna metro is frozen again. What can we expect in the AM?
Posted by: Sara in Oakton | February 12, 2008 8:10 PM
The infamous look of ice on bare branches is beginning to appear in Bethesda. Slid on my sidewalk while walking my dog for the final time today. My side street was still just wet though.
Posted by: Peter | February 12, 2008 8:17 PM
I can't see any ice, but it is slick as anything out there.
Posted by: Period | February 12, 2008 8:25 PM
temperatures slowly but surely rising here in NWDC, up from 26 to 28. hoping that this trend will not continue, but know it will.

Commute home from DC to Herndon - 2.5 hours
Treacherous conditions.

Icicles forming. Grass caked over in ice.
Posted by: Peter | February 12, 2008 8:38 PM
How can you people be rooting for an ice storm? This is dangerous stuff. I'm glad you want peoples lives in danger so you can get out of school.
Is this coastal that may develop tomorrow likely to be significant? I have to be in court at 9:00 AM on Thursday, and worried about getting there.

Posted by: Peter | February 12, 2008 9:01 PM
Southside FFX: C'mon, I think you can make your point without painting anyone with the darkest possible brush. No one wants people's lives in danger - you can remind kids that this is serious stuff without lowering yourself to levels that bother you in others. Play nice? :-D
Posted by: ~sg | February 12, 2008 9:03 PM
Another classic example of underforecast cold-air damming. This lack of accuracy in the computer models, with cold air trapped in the lower boundary layer east of the mountains, and the inability of warm air aloft to dislodge it, is notorious here in the D.C. area. This time, though, it could have serious consequences......this is potentially a very dangerous situation setting up tonight. I hope nobody loses their power......or worse.
Posted by: Mike | February 12, 2008 9:07 PM
Attempted to walk to back entrance of NIH in Bethesda at 8pm and had to give up because all the sidewalks were completely iced over. Instead opted to walk on the main path to metro that was treated. I thought I could overcome the icy sidewalks and walk on the grass - which is very difficult to do because you have to cross sidewalks to reach more grass.
Met some non-icy sidewalks at WoodleyPark metro, much to my glee. Duke Ellington bridge was getting icy on sidewalks, but definitely still walkable when dragging feet.
Once I turned off Calvert/18th Street, things got progressively worse and at one point I was hanging on to a drain pipe looking for a way off the sidewalk.
I finally had to give up and walk on the road.
Be careful out there!! I completely underestimated how bad it was - and now I'm just happy to a home before it gets any worse!
Posted by: tjd | February 12, 2008 9:09 PM
According to Pepco, outages are currently confined to 2 zip codes in Northern MoCo and 2 zip codes in southern PG county.
Posted by: Peter | February 12, 2008 9:09 PM
shirley: I'm thinking at the very least a 2 hour delay for everyone getting ice in the ice warning right now, if the temperatures stay down there could be quite a few closings. But, I'm not the expert/decision maker, so that's just a biased opinion ;)
Southside FFX: I'm looking at this from a purely "snow day" point of view, I'm not rooting for accidents and injuries and stuff! Just a snow day!
Posted by: weatherdudeVA | February 12, 2008 9:10 PM
I have 2 candles burning and the down duvet here on the couch just in case as I watch the Westminister Dog Show. LOL.
Mike...any guesses on if this will be an all night ice event, or will it warm and turn to just rain at some point?
Posted by: Kim in Manassas | February 12, 2008 9:11 PM
Southside - Agree with you. It's treacherous out there and incredibly unsafe. I wouldn't wish an ice storm on anyone.
Posted by: Ivan | February 12, 2008 9:12 PM
Southside FFX: I know you know that we don't want anybody to get hurt.
Posted by: Period | February 12, 2008 9:13 PM
tjd- Glad to hear you're safe. Hope everyone else is to!
Posted by: Peter | February 12, 2008 9:14 PM
It's just nice to have a free day once in a while ya know? You just can't control the weather so what happens happens.
And Ivan,
Who specifically did we wish an "ice storm" on?
Posted by: Period | February 12, 2008 9:14 PM
Looks like we need not worry anyway because those temps are on their way up, regardless of any cold air damming. The cold just isn't strong enough to hang on.
Posted by: Period | February 12, 2008 9:16 PM
Period: There's always tomorrow night ;)
Posted by: weatherdudeVA | February 12, 2008 9:18 PM
All, I think ssFFX was probably referring to this comment:
temperatures slowly but surely rising here in NWDC, up from 26 to 28. hoping that this trend will not continue, but know it will. - thejesse2442
As mentioned, ice is dangerous not only for travel but for infrastructure and power. Let's hope for everyone's sake the trend DOES continue. Now tomorrow night, let it be as cold as it wants ;)

Power outages spreading into DC and western Moco. Luckily, all zip codes still have less than 100 people out though.
Posted by: Peter | February 12, 2008 9:24 PM
About 3mm of ice on metal surfaces and 31 degrees in west Arlington. Streets just wet, but bridges slick as doo doo.
Posted by: Nader | February 12, 2008 9:26 PM
my bad about that comment, im sorry if that came off as brutish and rude. i didnt mean it to be that way at all. I'm just hoping for a snow day, which isnt going to happen, and do not mean harm on anyone and I hope that no one takes it that way. sorry, jesse
Posted by: thejesse2442 | February 12, 2008 9:27 PM
None of our regular posters here, including Southside FFX, thejesse2442 and all the rest too numerous to mention, ever means to be brutish or rude. We get nervous and irritable from crazy dangerous storms like this one, which is understandable.
Posted by: ~sg | February 12, 2008 9:33 PM
some of my colleagues reported earlier (around 8) that major accident(s) have closed 395S. they were waiting it out downtown.
Posted by: rishi | February 12, 2008 9:42 PM
Temperature holding steady (rising slowly?) around 27 here in Loudoun. Got bold enough to venture outside, and made it a foot out of my door before sliding and landing on my backside. Ouch. A smooth, solid, and slippery 1 or two tenths of an inch of ice on the sidewalk here. Also heard tires screeching (on ice!?) on the road behind the house. Be careful, all, if you must go outside or drive tonight or tomorrow morning!!!!

wtop radio weatherbug station is steady at around 28.4-28.6 all of my closer thermometers about that same. i went outside, couldnt tell if it was doing anything. concrete was mainly just wet, just a little ice on the tips of the stairs. hope everyone is doing fine out there. for whoever is with out power, my thoughts go out to you.
Posted by: thejesse2442 | February 12, 2008 9:59 PM
Power still on in East Silver Spring. Wife sick, my legs hurting even before I fell. I want the temperatures to go above 32 NOW.
Posted by: Murre | February 12, 2008 9:59 PM
In Germantown / Boyds, my sidewalk is one solid sheet of ice. Can't imagine anybody getting around, much less driving on this. Seriously doubt schools would be opening on time in MoCo tomorrow -- a delay is almost certain, closure is a possibility.
Posted by: Josh | February 12, 2008 10:03 PM
I think all MD schools will get 2 hour delays. Aleganny already got a 2 hour delay and that is where the heaviest Precip. fell.

Isn't Allegheny in the mountains so they are better prepared?
I guess if it's ice, no one is really that prepared!
Posted by: Peter | February 12, 2008 10:10 PM
It doesn't make any sense to call off school or give delays yet. There's more precip on the way, and if that happens to be rain, Allegheny will look pretty dumb (although they have about 25 snow days a year right? =]).
Posted by: Period | February 12, 2008 10:11 PM
Kim of Manassas, that answer is a tough one, but I wouldn't bet on the warm air aloft pushing out this sub-freezing boundary layer anytime soon. Keep your fingers crossed, the flashlights ready, and some nice blankets or a comforter on the bed in case you have a power outage and lose heat. An outage is not guaranteed but is certainly possible.
Posted by: Mike | February 12, 2008 10:13 PM
Mike,
That sub-freezing layer is holding on by about 2 degrees.
Posted by: Period | February 12, 2008 10:23 PM
I was thinking...
The "Nice Day!" criteria should be changed from 65-85 degrees to 55-75 degrees. Here, at least in the Spring and Summer, with our tropical humidity (woo hoo South) 85 can be ridiculously hot.
Posted by: Period | February 12, 2008 10:25 PM
Period: I concur.

Rain falling and 27 degrees at 10:40 p.m. in Manassas.
Posted by: manassas45 | February 12, 2008 10:40 PM
Just got another one of these....
The NWS reports Ice Storm Warning for Prince William County.
Description: ...ICE STORM WARNING REMAINS IN EFFECT UNTIL 7 AM EST WEDNESDAY... SEVERAL ROUNDS OF FREEZING RAIN ARE EXPECTED TO MOVE FROM SOUTHEAST TO NORTHEAST ACROSS THE AREA OVERNIGHT INTO EARLY WEDNESDAY MORNING. ICE ACCUMULATIONS OF AROUND A QUARTER OF AN INCH ARE POSSIBLE BY EARLY WEDNESDAY MORNING. THIS MAY LEAD TO SIGNIFICANT TRAVEL PROBLEMS OVERNIGHT INTO THE RUSH HOUR OF WEDNESDAY MORNING. THESE AMOUNTS OF ICE COULD ALSO LEAD TO DOWNING OF TREES AND POWER LINES. AN ICE STORM WARNING MEANS SEVERE WINTER WEATHER CONDITIONS ARE EXPECTED OR OCCURRING. SIGNIFICANT AMOUNTS OF ICE ACCUMULATIONS WILL MAKE TRAVEL EXTREMELY DANGEROUS. TRAVEL IS STRONGLY DISCOURAGED. IF YOU MUST TRAVEL...KEEP AN EXTRA FLASHLIGHT... FOOD...AND WATER IN YOUR VEHICLE IN CASE OF AN EMERGENCY. ICE ACCUMULATIONS MAY LEAD TO SNAPPED POWER LINES AND FALLING TREE BRANCHES THAT ADD TO THE DANGER
Posted by: Kim in Manassas | February 12, 2008 10:45 PM
rain is falling here in NWDC with a temperature of around 28.5-29 degrees. patiently awaiting capwx forecast. NWS scaled back there call for rain/snow tomarrow and likely snow tomarrow night to rain and rain/snow but in forecast discussion still suggest 1-3 inches of snow in CWA. looking forward to your input, jesse
Posted by: thejesse2442 | February 12, 2008 10:56 PM
Ok, I demand 2 Snow Lovers' Crystal Balls. One for DCPS, and one for everyone else. DCPS is notoriously bad for never cancelling or delaying. We haven't had a delay, early dismissal, or evening activities cancelled ALL YEAR LONG.
My prediction - EVERY single school at least two hours delay, some closed, with DCPS open on time.
Posted by: dcteacherchic | February 12, 2008 10:56 PM
It's true. DC is stingy, but it's always just a degree too warm there.

Posted by: MOCO NO SCHOOL PLEASE | February 12, 2008 11:07 PM
I just sliced my finger open on the ice. Watch out for the embedded sleet pellets in the ice on the cars and the railings and stuff. Happens to me every year, LOL. The little bumps and sleet pellets in the ice are as sharp as razor blades. My stupidity I guess for going outside...
I have to go to bed in a few minutes because I have to ASSUME schools are going to be open on time. Gonna bum me out if I don't get to see the 11PM forecast.
Fox5 is running a thing right now about people being trapped in their cars for the last 7-8 hours on the ramps and mixing bowl and stuff. They're saying if you have a loved one that hasn't come home yet, call them and they'll tell you if they've been contacted with the status of your loved one.
Last time I heard them talking like that on the news was Katrina and 9/11. This is really REALLY serious...
Posted by: weatherdudeVA | February 12, 2008 11:08 PM
A friend of mine who works in DC and lives in Woodbridge just made it home.....SIX HOURS after she left work. She said the mixing bowl is a nightmare.
