Good Morning

We had heavy rain this morning and now it is just pretty much a mist.

0.46 inches In the 3 hours preceding Mar 21, 2011 - 04:54 AM EDT

The event later on in the week, bufkit Nam is saying we could get 5" of snow.

GFS is saying no way.It would like to give us 0.82 of rain.

At any rate this is going to be a heck of a first week of spring.

Like the NWS discussion

http://forecast.weat...1&highlight=off

...AN UNSETTLED AND POTENTIALLY WINTRY WEEK LIES AHEAD FOR THE

REGION...

A FRONTAL SYSTEM MOVING ACROSS THE AREA WILL BRING A POO POURRI

OF WEATHER TYPES TO THE REGION TODAY

AS THEY SAY IN ENGLAND...WE ARE SEEING A VIRTUAL PIG'S BREAKFAST

OF WEATHER EARLY TODAY WITH RAIN...SNOW...SLEET...FREEZING RAIN

AND EVEN SOME THUNDER WITH SMALL HAIL THROWN IN FOR GOOD MEASURE.

THE STORM SYSTEM CAUSING OUR WEATHER VARIETY-PACK IS CENTERED OVER

WESTERN LAKE ERIE AT THIS HOUR AND WILL MOVE DOWN THE ST LAWRENCE

RIVER SWEEPING A FRONT THROUGH THE AREA DURING THE DAY.

06 GFS came in somewhat colder. We'll see if that is a trend.

Early next week looks really interesting right now.

Well the 12z NAM continues to be on the cold side of the solutions, spreading major amounts of frozen and freezing precip to a good portion of PA. Interesting to note that the 6z GFS came in colder than previous runs too, giving UNV a significant period of icing. I'd say watch for any southward shifts today.

Also, we had a bout of sleet last night, and a thunderstorm this morning. Pretty sweet for the first full day of spring! :thumbsup:

Is it far-fetched to say that we have a chance of seeing more rain while NYC sees more snow from this event? That scenario is on the GGEM and GFS.

they can have it, i'm over winter...give me 60's and sunshine. i think this is mostly rain for s-central PA...then advisory snows up north further with the potential for warning snows.

It was about 38° with drizzle when I went into class at 10:30, and 63° and sunny when I came out at 1PM....nice.

Several of my coworkers are refusing to accept what's coming. They are convincing themselves 60s and warmer from here on out with no more snow. They are going to be unhappy campers starting when they wake up Wed am.

My roommates are none too pleased with the idea of cold weather and possible frozen precip either.

Latest from Eric Horst...interesting.

* Spring Arrives. Winter Returns. *

spacer.gifnew-specialWx2_r3_c1.gifspacer.gif

Spring officially arrived on Sunday evening, but today will be the last Spring-like day (with highs in the 60s) for at least a week, perhaps more. After a five-week stretch of mainly above-average temperatures, the return of a blocking pattern across Canada and the north Atlantic Ocean will make for a relapse of late-winter conditions for the rest of March, and quite likely, in early April. I see two or three significant storms to deal with over the next ten days, with one coming Tuesday night into Wednesday night, another arriving sometime over the weekend, and a third possible the middle of next week. With the renewed blocking forcing the storm track southward, we're back into the pattern we saw in December and January with storms tracking to south of PA. In mid-winter, such a track favors snow across most of the Commonwealth; however, in late March this pattern favors snow in the mountains and cold rain or a rain-snow mix here in the lower elevations of southern PA. While I can't rule out a little accumulation in our area from one of these storms (with this first system, the best chance to see a little snow here in Lancaster is before dawn Wednesday and again maybe Wednesday night), I do think there will be accumulating snowfall in the mountains (and many areas from I-80 northward) with 3 to 6 inches quite possible in spots! And that's just with the first storm--the systems coming this weekend and next week might track even farther south and should have slightly colder air to work. So before this pattern runs its coarse, it's my bet that we WILL see some wet flakes here in Lancaster....and some spot in the mountains of WV or PA will likely see a foot or more (aggregate total) of Springtime snow.

You gotta love the Nam. Even though it's over doing things alot. 15" of snow. :lol:

Man the temps shot thru the roof this afternoon. My wirelesss thermometer has 73.8ºF currently. Officially KAOO and KUNV are 68 and 70 respectively. A pretty unique thermal gradient is set up through the commonwealth today, Places like Williamsport, Scranton, Allentown, and NYC are in the low 40s. Even Harrisburg isn't really touching the warmth of SW PA (56ºF).

With this next storm the potential snowfall is going to follow that trajectory. Hard to really even use the interstate system in PA to line up the rough axis but good ole US 322 is actually a pretty decent divider (when's the last time someone used that one?? :lol:). I think locations generally along/northeast of this highway have a good chance of seeing accumulating snowfall of at least minor amounts and then of course further northeast is where some more moderate snowfall could be in order. In southeastern PA the rain/snow line is probably northeast of this roadway by some distance moreso than along, but you get the idea. Northeastern PA/Pocono's seem like the best PA place to see some of the highest totals and also the NY border counties as well.

What?!? Possible winter storm this weekend?!? Where did that come from?!?:yikes:

The idea of a colder pattern with snow chances has been talked about for a while now.

It's amazing out. Just great.

I told a few people here that Wed am's commute might be kind of tricky. It also appears like some sleet mixing in.

I cant get over that thermal gradient/frontal boundary in Central Pa right now, 70 degrees in State College and 37.5 here in the Poconos.

btw, recieved 5.5 inches of snow this am at 1,254 feet here in Pike County.

Wow on both factoids.

Agreed that gradient is pretty neat. I didn't realize it was so warm to our west.

Here is surface temp map. Neat to see all the temps.

Mag as always thanks for your input!!!

Jamie you having been calling this storm for awhile.

Eh.....I was mainly going on what the experts were saying. There seemed to be a growing consensus.

39.8°F now, that should about do it wrt highs unless the warm push gets here soon.

That sucks. I hate when you get socked in like that this time of year.
