Snowshack Posted December 19 Share Posted December 19 Upton's AFD at least left the door slightly open for the MJO812 possibility The precipitation could have some banding to the north and west of the low center. This would be heavier precipitation for Friday afternoon into Friday night. Most models have this precipitation offshore but a few models have low pressure overall closer to Long Island, bringing this heavier band of precipitation across eastern portions of the region. If trend closer to coast occurs, snow amounts of a few inches could be seen for most of the region, locally higher possible. 1 1 Link to comment Share on other sites More sharing options...

Tatamy Posted December 20 Share Posted December 20 FWIW whatever snow that falls during the day tomorrow before 4pm will be melting on contact unless you have at least 500-700’ in elevation or are in a place that gets good rates. Link to comment Share on other sites More sharing options...

Yeah unfortunately the nam is mostly tomorrow during the day. We need more to fall overnight into Saturday Link to comment Share on other sites More sharing options...

Other models seem modestly NW but nothing that would bring the CCB in which would mean real accums. NAM is likely headfaking us again. 99% chance that any shot at accums comes with the inverted trough, and that looks better for NJ on the short term modeling than where I am, which is the middle finger zone between that and developing coastal storm. The inverted trough may shift around though or not happen at all. It's really a nowcast with these. 1 1 Link to comment Share on other sites More sharing options...

Bxstormwatcher360 Posted December 20 Share Posted December 20 Precip already breaking out in eastern nc,usually foretelling of a coastal forming right on or just off the coastline. 0z suites already picking up on that . 1 Link to comment Share on other sites More sharing options...

RU848789 Posted December 20 Share Posted December 20 We have almost the exact opposite of what we had ~24 hours ago with regard to the NBM, as it's showing <1" for just about all of CNJ/NENJ/NYC/LI, while every major global/CAM model so far (CMC, GFS, HRRR, NAM, RDPS, ICON and HRDPS) is showing 1-2" with 3" spots for just about everyone N of 276/195 in PA/NJ/NY. Last night we had much more snow on the NBM than shown on most of the major models. Going to be interesting to see what the NWS and others do with this info, especially if the Euro/UK are similar - my guess is the NWS will expand their 1-2" forecasts down to the 95 corridor in NJ/NY - we'll know soon.

Bxstormwatcher360 Posted December 20 Share Posted December 20 Another tick west for both the nam and gfs 6z suites. Nyc east gets into the main precip shield for a bit now,followed by the ivt. Also of note is the precip running up the delmarva coast currently. 2 Link to comment Share on other sites More sharing options...

The precip coming up from off the Delmarva coast and right along would be in the form of rain. There are no current reports of precip reaching the ground there. Temps there are in the mid 40s. Temps along the NJ coast and LI are in the mid 30s and that would support mainly rain during the daytime hours with snow possibly mixing in during any heavier bursts on LI. In any case no snow accumulations are expected during the daytime hours except for higher elevations well north and west. This is the theme of what the NWS is going with for the area. The best chance for snow accumulations for most of us is dependent on additional energy coming in tonight with the trough. We still have the possibility of the formation of the IVT as well for tonight. 2 Link to comment Share on other sites More sharing options...

Im not the most astute meteorologist but from the eyes it def looks west. 2 Link to comment Share on other sites More sharing options...

Just because there are echoes on radar doesn’t mean it’s snow. You are correct about the precip from the coastal being west however the precip field from that feature will move out to the east this afternoon. If anything accumulates that would most likely be this evening and tonight. Link to comment Share on other sites More sharing options...

The easterly fetch is bringing in the mousture for eastern areas which wasnt mentioned at all. I think we get some decent bands later on in any case. The squeeze play is on. 1 1 Link to comment Share on other sites More sharing options...
