Happy New Year


Today/s European model D+6 has real potential...despite the evolution and present placement of its major features.

The SE heat ridge has shifted its position once this winter...when it retrogressed about two weeks ago and widespread snows were observed in the NE. This time...a progressive planetary wave regime shoves the heat ridge well offshore by D+10 into the south-central ATL.

Is that soln reasonable given the how persistent the heat ridge has been to date...or might today/s soln be a tad too progressive? The implications for EC wx are significant if the soln truely is too progressive.

Also consider what/s progged to happen in the ern PAC where the model depicts deep layer WAA. Ordinarily...this would be expected to pump up or amplify the downstream S/W ridge.

In the event the SE heat ridge is not so progressive...and the wrn ridge b/comes more amplified by WAA...the wave length across CONUS would be shorter and the amplitude greater than presently progged.

Such an alternative scenario keeps the L/W trof closer to the EC where cyclogenesis would likely occur @ a latitude low enuf and a significant snowstorm is in play for much of the I-95 corridor.
