sauss06 Posted November 24, 2010 Share Posted November 24, 2010 Yes, even Joe Lundberg (the warminsta himself) indicated snow/sleet here in our area overnight. I was a bit surprised to hear that this morning. Even though the air temperature isn't impressively cold, it felt colder this morning than what the thermometer indicated. Dry, cold air mass in place... Yes it did. the thermo in my Tahoe said 36, but it did felt cooler. It really got windy when that front came through last night. Thought my gas grille was gonna fly through my french doors Link to comment Share on other sites More sharing options...
Storm Clouds Posted November 24, 2010 Share Posted November 24, 2010 That looks like some heavy rain is coming! Maybe some snow/sleet on the front end? http://www.nws.noaa.gov/radar_tab.php Link to comment Share on other sites More sharing options...
PSU8315 Posted November 24, 2010 Share Posted November 24, 2010 The dry air makes this forecast even more difficult. It will eat up some of the initial precip, but the cooling that will take place as the column cools from evaporation could help keep the colder air in place, especially if the precipitation comes down hard. UNV forecast sounding from 12z for 10pm tonight -- the huge dry tongue showing pretty nicely. Both models really don't fully get rid of the dry air until close to 7:00am tomorrow...

MAG5035 Posted November 25, 2010 Share Posted November 25, 2010 Happy Thanksgiving folks, so far this morning KJST (Johnstown) and KAOO (Altoona) are reporting light snow falling. Here in Bellwood had a quick bout of light snow and right now just some flurries. Took the handheld and the temp is actually just a shade under 38ºF with a 23ºF dewpoint here. Plenty of room to fall toward freezing once we get more appreciable precip. The precip on radar still a bit broken and spotty but it should be interesting when it starts building in better into Central PA in the next several hours. CTP held serve and maintained advisory package at the 10pm update. CTP 10:31pm update: .NEAR TERM /UNTIL 7 AM THURSDAY MORNING/...IT IS ALREADY SNOWING OVER SOMERSET COUNTY PER ONE RELIABLE SOURCE. LOCAL WRF12KM FROM 18Z AND LATEST NAM12KM HANDLING THE ONSET AND P-TYPE VERY WELL. THIS ALSO VERIFIES/JUSTIFIES THE FORECAST IN PLACE ALREADY. PRECIP SHOULD SPREAD E/N THRU THE NIGHT. TIMING MAY BE DELAYED JUST A FEW HOURS WHILE THE LOWER ATMOS MOISTENS UP...BUT ALL IS ON TRACK. WILL JUST SHINE UP THE WORDING IN THE ZFP AND WSW. SLIPPERY CONDITIONS ARE LIKELY BY DAWN OVER THE SW HALF OF THE AREA. Link to comment Share on other sites More sharing options...

CTP held serve and maintained advisory package at the 10pm update. CTP 10:31pm update: Yeah hopefully the dry air doesn't eat up to much of the precipitation rolling in. Looks like some of the precipitation to my west may be virga. My temperature is currently 33.8°F and with a dew point of 22°F. Seeming how the dp is so low, once we do end up getting some descent precipitation to get here it begins to cool the temps down to near the dp. I'm at least expecting 2" of snow and maybe a tenth of an inch of some ZR on top. Link to comment Share on other sites More sharing options...
PottercountyWXobserver Posted November 25, 2010 Share Posted November 25, 2010 Is it me or does it seem like the Low pressure system over Missouri isn't moving as far north as previously thought? It looks like the High to the north is blocking it from totally cutting up through the lakes. Right now the high is in perfect location for some nice CAD. Although I'm expecting the precipitation to completely turn over to rain, I'm curious to see how long I can stick with the frozen stuff before the switch.

When CTP updated the advisories around 10pm they actually did tweak the start and end times for particular groups of counties. For Potter County the advisory actually does not start till 9am and lasts all the way till 11pm. So it appears you might have mixed precipitation all day up where your at. Not sure if you'll get to 2 inches since the warm air aloft will probably get up there and change the precip to other things by afternoon, but then again did not expect things to begin as snow and continue to be snow down here in Altoona and Johnstown either. Will be fun to watch. Link to comment Share on other sites More sharing options...

Your right the WAA may cause everything to either be sleet or ZR. I will take whatever I can get as I know this really isn't a good scenario at all for descent snows. Its going to be a rough winter if we keep getting these storm systems cutting up through the lakes. The HP to the north may stay in place longer due to the nice blocking taking place in the maritimes. We will just have to see what happens, btw congrats on the met degree, PSU is a great place, I'm going to back and finish up my met degree in a few years.

Thank you, yea it was a long time coming finally getting that degree. Def a challenging major. Now the challenge is trying to get a job in the field haha. Yea a lot of times the CAD can hang on better than advertised and make for either a longer period of wintry precip or an even more bone chilling rain. Def not a fan of the return of the GLC domination so far this winter, though its early yet and plenty of opportunity to get in a better setup.

Blizzard92 Posted November 25, 2010 Share Posted November 25, 2010 Light to moderate sleet here 10mi northeast of Harrisburg. Link to comment Share on other sites More sharing options...
NJHurricane Posted November 25, 2010 Share Posted November 25, 2010 whilst making holiday pilgrimage last night hit snow/sleet mix in the Johnstown area and around the Tuscarora and Allegheny mountain tunnels. Temp dropped briefly to 33 according to the exterior car thermometer. It was enough for PENNDOT to salt and looked nice in the headlights. Link to comment Share on other sites More sharing options...
PennMan Posted November 25, 2010 Author Share Posted November 25, 2010 Mix of sleet and some pretty large flakes here now, 30 mile ENE of Harrisburg. There's a slight coating of mostly sleet on some surfaces. Currently 37.8°. Looks like some heavier sleet/snow NW of Harrisburg where we're headed for Thanksgiving dinner in a bit.

Happy Thanksgiving all! edit----Its sleeting again All sleet here now...some pellets are pretty rough...guess a few flakes are not 100% melted when they hit the low level cold air. If we had gotten some decent precip in here earlier this morning we may have had a chance for some minor accumulations. I'll take the coating of sleet on the deck, mulch and grass though. Nice to see a few flakes on Thanksgiving. Link to comment Share on other sites More sharing options...
canderson Posted November 25, 2010 Share Posted November 25, 2010 I'm in Munich. First part of today was sunny and 37, this evening it is 28 with a light/mod snow. So pretty. Saturday looks to be cold: sunny yet high of 22! I'm guessing Germany is where C PA's cold weather went. It's usually very similar in Munich and Harrisburg. Happy thanksgiving, everyone!

PottercountyWXobserver Posted November 26, 2010 Share Posted November 26, 2010 Awefully dissapointing event for me, I really don't think the Winter weather advisory even met the requirements here. The CAD really never stood its ground here, but places to the east faired better. On top of the cold air being scurried out, the north section of potter county had little precipitation to work with. At the moment my total stands at a paltry 0.30" while places just 30 miles to the south based on radar returns are up around an inch and a half . btw canderson hope you are enjoying Munich, I want to visit Germany and Austria real bad!

canderson Posted November 26, 2010 Share Posted November 26, 2010 About 6 inches of snowing Munich today, and still snowing at 5 pm. What's impressive is the cold, a high if 29 today and nearly all of Germany won't see temps get above freezing for at least a week. Crazy bout of arctic air over Europe right now.

canderson Posted November 26, 2010 Share Posted November 26, 2010 It won't. Unlike Harrisburg and the surrounding area, these people know how to handle snow. I swear every road and sidewalk was never covered more than a dusting despite some good snowfall rates late afternoon. Tomorrow we are going to Garmisch and the highest pointin the German Alps. Lots of pics when we return. Saw guys had a windy day, I dont envy you there. Link to comment Share on other sites More sharing options...
