PM Update: Cold, clouds increase Friday

By Jason Samenow

Temperatures are a good 15 degrees colder than the same time yesterday thanks to the Arctic front the pushed through yesterday. The cold air mass sends us into the deep freeze tonight but begins to slip away tomorrow as storminess develops to the south.

Through Tonight: Winds relax so the cold is not as biting. But clear skies and Arctic air overhead make for a less than warm evening. Lows range from the upper teens in the colder suburbs to the mid-to-upper 20s downtown.

Tomorrow (Friday): Morning sunshine is followed by increasing clouds during the afternoon. Light flow from the south helps temps reach the upper 30s to low 40s. Any precipitation holds off until at least 8 p.m., so no weather problems for the evening commute.

Southern snow & ice: Arctic air has infiltrated all the way to the Gulf of Mexico at the same time low pressure is starting to organize. The result has been snow and ice in many places not used to it. Freezing rain and sleet has been falling in Alabama and Mississippi. Farther west, snow and ice is expected to develop around the Houston area.

Hey guys, the Denver Post link is actually going to the Daily Mail photos. They are amazing photos, especially the one in Japan!

The 60 hr 12Z GFS did give us a blotch of .10 to .25 (Saturday afternoon), so it probably wasn't out of line with such a powerful upper air system to think a burst of snow could be possible.

The 18Z NAM seems to be taking the vort max further north and giving PA some pretty good snow whilc dry slotting us. It will be interesting to see if the 18Z GFS goes along with that trend.

All of the "SNOW" action is always happening, "West and North".. What about "SNOW" for the "EAST".. Does the "EAST" of the Washington DC area sit down in a low, low, hot valley or something? We keep getting screwed out of snow...

Headed to Central Pa. 2morrow for Super Bowl weekend, at least the weather is dry this time. Got hit by near whiteout cond. 2 yrs ago between Altoona & State College.
Looks like I may c some snow up there on Sat., they have also been in a snow drought this winter. They've only had about 8" of snow all winter.

@ana_b

I fixed the Denver post link. Thanks for the heads-up.

Milwaukee Journal has a nice photo montage of the big storm in my home state. I recall one or two big storms like that when I was growing up, but they haven't gotten dumped on like this in quite a while I think.

Bella, seemed like this winter started off with the east getting all the snow...

Jason/others, is the source of the somewhat colder temps on Saturday the counter-clockwise flow around the low? Thx.

VaTechBob, enjoy the game and the PA snow (if the NAM verifies).

The 18Z GFS gives us a little something Saturday afternoon, but nothing in PA like the NAM showed.

Now the 18Z is showing a near miss next Monday. Another very powerful upper air system, but the surface isn't cooperating.

The Thursday storm. Now they are showing snow changing to rain and back to snow before ending. Not the storm of the century but an interesting event.

After the Thursday storm they are showing some of the coldest air in many years coming here.

The GFS might be in one of its hyperactive modes, so all this should be taken with a grain of salt.

not sure where to post this - on the snowstorm thread or the pm update thread... so i did both.

wow...18z GFS:
more moisture (12-15" if snow),

but we're flirting w/the rain/snow line.

frontieradjust, you said,
"The GFS might be in one of its hyperactive modes, so all this should be taken with a grain of salt."

...but...that would melt the snow...

Yeah walter, thats a big storm but if this keeps trending a bit more west, we will have to worry about flooding, or if it goes more east by next thursday then we'll have to worry about a repeat of last february blizzard.

Just FYI, Topper Shutt predicted an all-snow coastal storm for next Thursday on his 6pm and 7pm newscasts.

I wonder what makes him so sure that it'll be all snow? We all know that it's still a long way out and the models are more than likely going to flip several times between now and then.

He is in a way the Joe Bastardi of local television. Well, maybe that's a stretch, but he does come close at times. I still prefer good old Bob Ryan over anyone else.

Anyway, I wouldn't be surprised if the 00z is a complete miss, considering it is unusual to have such agreement this far out, but we shall see.

Sue Palka just said we can expect ice and sleet until sometime saturday morning, roads could be slick sat morning. Doug Kammerer says this will be an all rain event for us. No one has any idea it seems as everyone is talking snow, sleet, frz rain and rain :/

Posted by: KRUZ | February 3, 2011 10:55 PM | Report abuse

OLE SUE predicting ice and sleet..i can see that..

but asking her to predict snow is like pullin teeth..lol

Kruz, as is often the case, it's a bit of a close call. I heard Doug Hill on wtop say something like that it won't be a problem unless you have travel plans at 3, 4, 5:00 Saturday morning in which case you could see some sleet.

RJ, forecasting is complicated, but these oversimplified instructions will help get you started: http://www.ehow.com/how_2176996_read-weather-model.html
