I-83 BLIZZARD Posted February 13, 2014 Share Posted February 13, 2014 I am as disappointed and impatient as you. 18-24 is fairly pedestrian. We need stalling and banding for the 24-38 mark. Link to comment Share on other sites More sharing options...
Jns2183 Posted February 13, 2014 Share Posted February 13, 2014 I believe CTP mentioned that better bands were to spread into the area between 09-12Z due to the frontogentic lift comes into our area. Also between 12Z - 0Z we would have a 3-5 STD DEV above normal eastern anomaly that will be feeding into this frontogentic lift. So I'm guessing we will see much better bands around 6-7ish Link to comment Share on other sites More sharing options...
KPITSnow Posted February 13, 2014 Share Posted February 13, 2014 Question. I'm looking at obs from around the dc area, and they are all reporting light snow and 1.5 mile vis. Why, with those heavy returns, nothing heavier? Link to comment Share on other sites More sharing options...

Why, with those heavy returns, nothing heavier? Trust me, it's beyond thumping in DC right now. I can confirm with multiple reports around DC and thundersnow being reported south of DC in NoVa around Arlington. Radar in MD is stunning and starting to break the wall at Pa line. It's going to rip something furious probably by 4am. In fact, HRRR and Euro say same exact thing on timing. Lock and step. Just awesome.

MAG5035 Posted February 13, 2014 Share Posted February 13, 2014 Radar is starting to improve for the AOO-UNV crew. Snows picking up some here, the steadier and heavier stuff is starting to make a press into central after the front edge kind of sat around for a bit. Susquehanna Valley is about to be overrun with significant snowfall rates of 1-2"/hour. Patience is going to be a virtue in our neck of the woods, but the trends continue to look quite good on the near term models. RAP has been steady the last few runs getting 6-8 in Altoona and State College and 4-6" all the way to Clearfield (with remaining backlash to go beyond 18hrs), HRRR had 4-6 for AOO/UNV and about 2-3 for Clearfield out to 15 hours with more to go.

Cashtown_Coop Posted February 13, 2014 Share Posted February 13, 2014 I had 2" at 230. Still light snow. I've been getting a little sleep waiting for heavier bands to push in. Reports of 8" from 1tier of counties to my south. 21f Cashtown Link to comment Share on other sites More sharing options...
Voyager Posted February 13, 2014 Share Posted February 13, 2014 Just woke up. First observations, thoughts, and speculations. We have one inch of new snow on the ground with what is still seemingly light snow falling. I hit the sack about 11:00 or so last night so I really don't know when the first flakes started falling here. As the shield of precipitation advances northward, it almost appears as if the heavier stuff (20+dbz) doesn't want to get too far into PA. I'm wondering if that is going to be an issue as the day unfolds, or if it finally does advance more northward. That concern comes from some of the models showing, yesterday, that PA would be in somewhat of a "lull zone" while areas to the south, and then northeast, see heavier snow and larger accumulations. Time will tell on that. For now, the placement of the precipitation looks just like modeled, but, for some of us PA folks, the rates aren't up yet.
