wdrag Posted January 20, 2021 Author Share Posted January 20, 2021 Good morning- It's Wednesday Jan 20 - 25th-26th: 00z/20 ENS a bit further south, but main change in my view...I90 north is definitely drying. I see the 06z/20 GFS op gave up on everything 25th on MD northward... yikes-i don't think that is going to be correct? Meanwhile: NAEFS continues pretty fast on the 25th onset and 0.4 up to I84 with variability. Let's say this is a bit too high... I still think we're looking at .1 to .2 to I84 and .2 to .4 along and s of I80 in our forum with ice involved along I95 and potentially a period of rain parts of LI, NJ coast. All dependent on whether the flow turns wsw at 500 per the GEFS over LI or never backs to more than 280 (EC op). Since we're still at D5-6..I'm leaning NAEFS with contributions from the EPS/GEFS and 2" up to I84 and potentially a swath of 3-4" near ice change zone in NJ. I'm staying with the original topic til I'm sure it's south. NAEFS (GEPS) will have to back off. Right now, I've no certainty of that. Will check back late afternoon. Have a day. 1 Link to comment Share on other sites More sharing options...
wdrag Posted January 20, 2021 Author Share Posted January 20, 2021 Good thing we can enjoy some of the snow this morning: 06z/20 GEFS is a disaster... relatively dry through much of Jan. Have my doubts but it's just another set of options and imo, needs to be treated with consideration but not gospel. Once I see the GEPS dump this threaded event, then I'm convinced. Think it's all based on the backing wind at 500MB (short wave strength) coming through NyS-PA-LI 15-26th. If predominantly 270 or 280... not good. All I can do is monitor and accept the future trends. Link to comment Share on other sites More sharing options...
MJO812 Posted January 20, 2021 Share Posted January 20, 2021 This storm for the 26th looks more like a SWFE to a which usually trends north. We finally have blocking on our side so this will not get as far north. Question becomes where is the fine line. Link to comment Share on other sites More sharing options...

SnowGoose69 Posted January 20, 2021 Share Posted January 20, 2021 1 hour ago, bluewave said: The perfect thread the needle for us would be the big -PNA trough out west pumping the SE Ridge enough to avoid suppression. But the -AO remaining just strong enough to prevent a mix and low tracking too far north. So my guess is that there will be some very interesting runs in the coming days. Since DCA to NYC has never seen a significant snow with the rare -1.5 PNA and -1.5 or lower AO combination. Hopefully, this event will push the bounds of what is possible for a snowstorm with such a -PNA. Yeah I feel people in DC are getting too happy about this event given there is an SER...this is not 2/6/2010, even if there is blocking in place. Its gonna be next to impossible to see a significant snow event that stays PHL south with the degree of SER we see (and lets face it, its ALWAYS underdone the last few years at this range). I think this could easily be a setup where even this region goes snow to rain Link to comment Share on other sites More sharing options...

I think this could easily be a setup where even this region goes snow to rain But the last several years, we had a +NAO which allowed the SER to flex and that’s why we kept seeing the last minute “north trend” we never had a west based -NAO block pressing down. The flow is also screaming across the CONUS next week, this is only going to get so far north before it hits a brick wall. That block means business, it’s not going to let the SER flex and cause a north trend. I think the threat is suppressed, not trending further north Link to comment Share on other sites More sharing options...
