If we can get the snow in here by let's say 19z... and get 4 to 6 hours of heavy snowfall... I would take that before we mix. Also seems that the dry slot will be moving through our area too on most models... so hopefully by the time we get above freezing its just some light rain and the dry slot ends our precip so we can at least enjoy the snow and ice that is left lol Exactly. While this storm has some unique and interesting features, it's still a very typical setup and outcome for the track. Prob 50% or more (stat guys can check) of all our measurable snowfalls are mixed around the cities and burbs. We do it often and at times we do it really well. If climo really takes over, not much above freezing rain is going to fall. I've been thinking that's how it's going to play out but models had too much spread to discuss. 4 Link to comment Share on other sites More sharing options...
jayyy Posted January 14, 2022 Share Posted January 14, 2022 Knew when I woke up and there were only 4 more pages of content that 00z and 6z weren’t that great. Still 48 hours away. Let’s see if we’ve got any last minute magic in us 1 Link to comment Share on other sites More sharing options...

The upper levels weren't that much different Synoptically it’s the same. It’s simply “seeing” the mid level warm layer now as we get closer. We knew this was a risk with that screaming SE flow. Been talking about it for days. The Gfs just suddenly sees it. 2 Link to comment Share on other sites More sharing options...

LWX disco mentions the wind 'threat' too with gusts approaching 50 mph as a possibility. I'd bet that map is a bit overdone but it should be pretty gusty Sunday night. 2 Link to comment Share on other sites More sharing options...

PhineasC Posted January 14, 2022 Share Posted January 14, 2022 Hopefully the rain washes the snow off the driveway and sidewalks before it departs. Shoveling 2 inches of frozen, moisture-laden slush really sucks. Expecting 1 inch with rain here. Looks like 15"+ in NH, but I am stuck here right now.

mappy Posted January 14, 2022 Share Posted January 14, 2022 Not sure if its been mentioned, but something brought to my attention on twitter is the dry air ahead of the WAA and how quickly it erodes as precip moves in. so... yay. Link to comment Share on other sites More sharing options...

Eh...I don't think that's as big a deal as it might seem. That WAA is fierce. The radar will probably get the DC snow hole look by like 15-16z on Sunday and it will start snowing on time around 18z. 2 Link to comment Share on other sites More sharing options...
WxUSAF Posted January 14, 2022 Share Posted January 14, 2022 One small detail I've been wondering about seems to have appeared on the 0z Euro (at least). The annoying/helpful/disastrous northern stream shortwave makes a pretty good pass for the metro areas late on Monday. And it's strong obviously. Euro spits out some light snow with it. I think that's very plausible and could add C-1" later on Monday. 7 Link to comment Share on other sites More sharing options...

The placement of the high just doesn’t seem ideal. Surface winds look they’re out of the east by the time the precip arrives and the 850 layer looks potent out of the se. I’m assuming it’ll be a battleground for a few hours, though I guess a quicker arrival or slower departing high could help with that. Link to comment Share on other sites More sharing options...

Snowfan96 Posted January 14, 2022 Share Posted January 14, 2022 As we get closer to the event, the hi-res models will better capture how quickly the mid and low levels will warm on the screaming ESE flow and the snow and ice totals will come down in line with that. We all knew it was inevitable. Link to comment Share on other sites More sharing options...

I have been cursed this year with virga Hopefully we will avoid most virga since this is a big storm blasting through here quickly. It's not a slider south of us where we are on the northern edge. Won't be much time for virga since the minute the precip starts we will be able to see the back edge on radar already. LOL Link to comment Share on other sites More sharing options...

nj2va Posted January 14, 2022 Share Posted January 14, 2022 Yeah, this isn't a virga setup at all. The WAA and those winds screaming from the SE at the 850 level will come in like a wall to get rid of any dry air in the column. 3 Link to comment Share on other sites More sharing options...

That's why I think it comes in light for a few minutes... then it's hot and heavy until the switchover. Rates will be over 1" per hour for however long we can snow IMO 5 Link to comment Share on other sites More sharing options...
Snowfan96 Posted January 14, 2022 Share Posted January 14, 2022 The intensity of the WAA should overcome the low level dry air rather quickly, so I think any virga will be short-lived. Link to comment Share on other sites More sharing options...
