Expand I think that’s old days bias, and at longer leads. I tell you what, if it would focus on the northern piece of energy closer to the base of the h5 like the Nam did, that run would have been drastically better.

But as you say, if we're actually seeing more interaction, hopefully the surface and precip will "respond" in upcoming cycles. Link to comment Share on other sites More sharing options...

Expand Honestly…If all the globals looked like the NAM right now I’d be sweating bullets that it could trend further NW given a closed H5 and h7 low tracking through Ohio and PA. Honestly that’s normally a snow to mix type track for us. For reference March 2017 Dec 2020 and Feb 2021 had similar mid and upper level tracks. If I was looking the h5 of a long range run like I often do first when I flipped to the surface I’d kinda expect to see a central PA snow jack type storm. The extremely cold air mass and 1050 high helps mitigate that here. But remember when someone was throwing out March 2001 because of the h5 similarities. That was modeled to miss us south all week and Mets were saying what I am now, that it “should” be more north. Then at 48 hours it came north…and just kept going lol. Now wouldn’t that be the ultimate kick in the nuts. If tomorrow all the models come back north and show us getting 20” and we throw a party.

Expand Out in mid range, it kept looking to me like a place kicker. Just booting the southern wave out of the way and de-energizing it as it does it. I didnt want to post that it made sense because of the reception it would have had lol. Without the lobe hanging around, the WAA piece would easily stream to DMV. Lift is getting robbed in the dead space gap. We dont deal with setups like this enough to have much precedence. A full blown TPV like 2014/15 is real energetic and lights stuff up. This isn't a tpv like that. It's just a cold cutoff ball with potential energy. I know you know this. Just finishing my thoughts 2 Link to comment Share on other sites More sharing options...
