Arctic April

18z GFS is bringing the storm system in about 2 days earlier then the 12z Euro did. Does not look as strong as least.View attachment 38291

It’s actually been trending in a direction more favorable for severe with that NS energy slowing down allowing a larger warm sector and less CAAC2333287-3160-49BF-A9D1-E5AFE2DD1AAD.gif

Yeah the solutions overall are varying pretty wildly from model to model, but we're nearing that time of the year in the deep south where deep layer shear becomes the limiting factor for severe more often than not instead of CAPE. Hopefully, this takes most of our minds off the virus for a little while.

I was comparing it to the Euro but yeah definitely a solid warm sector this run. Low to mid 80s in the Carolinas and parts of Georgia out ahead.86D21EF1-8AC0-41D4-89D7-6969E7574C2F.png
 
According to the Joint Typhoon Warning Center (JTWC), this is a 60 knot tropical storm in the SW Pacific. Just to put things into perspective how wrong they are on the initial intensity right now, that dark gray -80C ring coupled with a clear eye is a cat 5. This storm is probably already a cat 2 & it's undergoing rapid intensification

Taking a deeper look, I'm not buying the op GFS, it's faster than every model (even vs its own ensemble) w/ the trough ejection at day 5.

One of these things is not like the other.

To not bury the lead, the real story is that the 18z GFS accomplishes a triple phase and the storm under goes Bombogenesis.

Pretty close to being an historic late-season winter storm for the Midwest / Northeast.
