RAH DISCO:


LONG TERM /THURSDAY THROUGH TUESDAY/...
As of 300 PM Tuesday...

Broad cyclonic flow will encompass the eastern US Thursday and
Friday, with westerly mid-level flow and mild weather on
Thursday. A stronger shortwave moving through the Great Lakes
Thursday will propel a cold front into the Mid-Atlantic states
and eventually south through NC on Friday, Limited moisture
return ahead of the front, owing to the westerly flow, will
limit POPs to just a slight chance of showers Friday afternoon.
Highs Thursday and Friday look to be in the upper 60s to mid 70s
both days, warmer in the south on Friday with 20-30kt
prefrontal wind gusts.

The bigger story for the weekend will be a fast moving storm system
forecast to race through the OH/TN Valleys and across NC/VA Sat night
and Sunday. Models have trended further south with the track of
this system along the mean baroclinic zone, which suggests better
chances of wintry precip, given critical thicknesses supportive of
snow along the NC/VA border. However, the parent Canadian high
supporting the surge of cold air is far to the northwest in south-
central Canada. Recent GFS runs develop a strong surface low off
the Carolina coast St night, but a deep cyclone is not supported by
ensemble forecasts, and the main shortwave is still multiple days
away from being sample over the Pacific Northwest. Thus, confidence
in measurable snow and/or wintry precip is not high and likely won`t
be for a couple more days.

Behind this system, northwest flow looks to continue, with temps
near normal early next week.

GFS says big storm big cold, euro says weak storm little precip... Allan Huffman seems to agree with euro

GFS Para agrees with euro

Sure, why not. Anything can happen lately. Lol. Its only a possibility. Thats all the results are but Euro has done strange things lately so who knows. Probably too extreme. I believe the snow chances more then the extreme cold...

Yes, record. Since Feb was one of warmest on record I think we can easily be colder. Maybe 1 more arctic blast at end of month would lock it in.

Kinda makes it fun when models dont agree even 4 days out. Headaches too. Lol nice disco from them.

Forget Friday.
Forget Sunday.


Models hinting at something for next week too.


New GFS18z has a Blizzard for Eastern Long Island and the MA Capes. LOLOL.

A 974mb Bomb near benchmark area (Latitude 40N/70W)




Euro and the Ensembles are hinting at the coastal storm too while its cold enough at the mid levels for snow from DC northward

[muslim12]

Insane, GFS now has a SC/NC storm; forecast for weekend warmed up though.

[Cambium]

I don't know which storm to focus on. LMAO


Here's 1st Snow Wave Friday. Small, Weak but dropping snow. NWS says 4-6" for that area in PA there.

Take a look at the snow ratios on Friday morning.


Left showing the precip type. Right showing the snow ratios. Looks like fluff stuff for Adirondacks but note the snow is very light.

Segment on TWC was just on. 3 storms and the 3rd one may be a biggy?
