February 7th Storm Threat Discussion/Obs

Other then the NAMs, the early hints across other 12z guidance (hrrr, ARW, NNB, HRW, Icon, RGEM) is a continuation of the trend towards less amplified and thus less qpf. That’s bad for everyone.  With marginal temps the extreme rates are necessary to get good accumulations. This is a setup where there is an exponential effect. It’s not like .8 qpf = 8” and .5= 5”. This is a setup where .8 could be 7” and .5 could be 1- 2”.  6 hours of moderate snow won’t work here. We need that OMG face banding on the coastal plain.

Thanks. But apparently I need to post less!

No. Scared! Terrified. But i’ll forget everything once it starts falling.

It’s it’s snow, be happy with what you get

We have potentially one of the best periods of winter in a long time coming up.  I would think everyone is somewhat happy.  Yes?

Amen

nam is inspiring; the latest gfs was not.  need any further se shifts to stop and probably could use one more move nw.  i don't think light rates will cut it with this storm...we've learned that lesson already.  also seeing some hints that there could be a zone in between the better rates closer to the lp track and higher elevations.  i think i'd rather be closer to the low track with this one for the best lift and take my risks with temps.

Won't work here for what?

This reminds me of that event we were supposed to get blitzed with rates early in the AM, couple years ago. Rates and intense banding didn’t really pan, and we got like 1.3” in Baltimore. 

I think most need to keep their expectations in check. Lot of our snow is going to come down to who gets under good bands. And that’s not something models are gonna predict spot on.

Your location has kinda been the snow anus of the region lately. And because of that (understandably imo) you’ve been a bit of a deb. Because of that though some probably just assume you are debbing even when your point is legit.
