Nope. Nope. Nope

I don’t think I’m in the mood for this again after yesterday.  RAH’s discussion from this morning:

“The sensible weather related to the pattern described above will
feature variably to mostly cloudy and cool conditions on Wed, with a
combination of stratocumulus in nely flow and increasing mid-high
level moisture in swly flow aloft. Low/mid-level warm air advection
will then rapidly strengthen overnight-early Thu, preceding the
aforementioned deamplifying shortwave trough and atop the cold air
damming surface ridge. Rain, another widespread soaker with over an
inch QPF, will consequently develop nwd and become widespread
overnight into Thu morning. And with the surface wet bulb freezing
line likely in the vicinity of the I-85 corridor Thu morning,
another episode of freezing rain appears likely over the
climatologically-favored nw Piedmont. Any such freezing rain would
be self-limiting and change over to a cold rain by late morning to
midday, given that the parent high will be in the process of
retreating through ON. Strong stability within the cold air damming
regime will be resistant to erosion, however, so high temperatures
on Thu will likely be much cooler than national blended guidance,
likely ranging from upr 30s and 40s over the Piedmont, to 50s (or
possibly some 60s) over the srn Coastal Plain.“

Definitely looks like another traditional CAD area storm.  As sick as I am of rain, I'll continue taking it over that stuff.  Unless this trends differently, I don't see anything (currently) to track for my area for the next 7-10 days.

I’m with you I was just above freezing this past event and I’m fine with that not having ice. Hope im as fortunate this next system also

FROM LARRY COSGROVE

This is a formula for entrenched, low-latitude cold and cases of heavy snow and ice. But given that the first piece of energy in the series will be further north, the scenario I have constructed is for a Colorado cyclone to progress eastward into Virginia, then curl up along the coastline of the Mid-Atlantic, New England and Maritime Province. Timing is uncertain, but using the ECMWF ensemble package, between February 25-28 should fit.
 
I do not think we get out of the rest of calendar winter without yet another major weather event. If the next two in the series, acting with a motherlode in the Great Lakes region like we have currently, an area from the Great Plains to the Eastern Seaboard (probably minus the Deep South, but you never know....) could be hit with major snow and mixed precipitation potential. Given that the 10MB circumpolar vortex is again unified and deepening, I think that we start to see meaningful warm-ups below 40 N Latitude in the last week of March. With thunderstorm threats.

But it's going to take some time, this time!

Nope.  Don’t want.  default_yikes.png

It would be fitting that the cherry on top of a winter pattern that scores everyone in the lower 48 BUT the upper SE while drenching us in 20 cumulative inches of 33 degree rain would be a significant followed by a straight brutal ice storm that causes a lot of damage...
