Honestly, having the EC side with snow right now is probably a bad sign. Especially the last 1-2 months. Not sure why other than to say we are in a pattern that it does not excel.
EC trended North with the main band of snow tonight though it was seemingly not as much about vort position as it was ground temps and precip intensity as there is mixed precip further down in the central and southern LSV even poking into MD. Does have several LSV 1" lolipops.
ITT2 has no real way to climb later in the GFS run. It really tries after it goes over Florida and sits off the SE coast for several panels. Mixed news for the spring flingers as the suppression is generally caused by a cold dome of high pressure/quite broad trough in the NE corner of the US. The trough is initially positively tilted which is not good for big storm chances of course. By the time it goes neutral it is to our east.
Yea, I agree improvements on both. The resulting low on this run of the GFS mauls Southern NE as it stalls/tucks. I think we need this displaced even further south for a big snow here...and to transfer earlier.
12Z GFS spreads moderate snow through much of PA Friday afternoon into the evening. Much of the LSV and SE a bit warm and a mix or rain. Primary makes it too far North and West to hope for a big coastal development scenario for us with ITT1 as the low spins up off thr NJ coast.
CMC was better than 0Z but both ITT1 and ITT2 start to spin up too far to our east as in both cases.
12Z Icon forms a low (ITT1) off the Southern VA/ N NC coast this weekend but snow is confined to far East PA where the rates allow overcoming of warm boundary layers. Just read a tweet from JB who said this will/could be the 3rd coldest March ever and the coldest since 1960.
3K Nam now brings accumulating snow into Lanco over the next 24 hours...for the MJS car topper request this AM. FV3, HRRR and 3K all on board for Lanco to see something. Rgem not so much. The main band on the 3K is farther north than the other Meso's I looked at. This wave was a N PA mauler late week which folded to NY only system only to come back and now POTENTIALLY get snow into SE PA.
NAM and HRRR both actualy have two "bands" of scattered snow or snow rain mix for the LSV Monday Night and then again Tue. GFS has ITT-1, 2, 3 and 4 (not necessarily snow on each but potential storms and potential snow.)
