ever the optimist to see a flake or two - the latest gfs indicates we may have a few falling here (going to be close).  the winds have picked up big time here and clouds moving in. not expecting much or anything but hey maybe i can see one or two pin size snow flakes later today lol

 

good luck to those in nc

and me LOL

My bad! Yea all of us across triad -triangle it's gonna be flip a coin. Some will get a nice coating and others will get screwed. nature of the beast with these. Just in our county between the 4 of us you will see a sig spread. You are no doubt in the best spot. hopefully this band that sets up n/s oriented from Triad to sandhills on every model comes to fruition and doesn't do a disappearing act this evening. Good luck!

I'm starting to think that band that drops through the eastern triad and south will leave the western part of the triad high and dry, while Gboro west to Burlington could see a pretty decent snow fall.  This trend seems to have been picked up on by nearly every model.  

 

Wouldn't be the first time that's happened. In fact, it's quite common. <_<

And it is projected to stay stronger and more defined as one piece of energy longer. Looks like about a 15 mile shift south as well.rap_namer_009_500_vort_ht.gif

This is interesting being that the local mets here in the east were saying they were probably increase their totals further south due to the southernly trend of the latest model run.. so there is still some uncertainty with this systems... with the warm temps around here any area in the east stands a chance of getting more snow than forecasted...

Afternoon folks, CONGRATS, for those whom will/May receive a dusting or Surprise this afternoon/evening..

I'm not Edmucated enough, to know if that vort digging deeper sith will even Help ILM here, close but NO cigar, UNLESS, we happen to get convection right here on/in the coastal Zone...

NWS upped our chances from 10% now to 20% chance of precip...

 

Its 57 now, blustery winds..

 

Near term /through tonight/...
as of 945 am Tuesday...temperatures on a quick uptrend early this
morning ahead in pace of hourly forecasts...and as a result have
bumped maximum temperatures up a few degrees into the middle 60s across
the central and eastern zones to the upper 50s over our far north
and west interior. The latest satellite trends show quite a bit of
sunshine is likely this morning into early afternoon. Cold air
advection will be strong and it will arrive this evening. The
sharp change in air mass will topple temperatures...and by 6z/1am
the majority of our forecast area will fall below freezing.
Because of blustery winds associated with this system...wind chill
values will bottom out around 10 degrees f around daybreak on
Wednesday which falls shy of a requirement for a Wind Chill
Advisory.

The primary concerns include potential minir accumulation of snow
tonight...if any...across our northern tier overnight. We will
also need to take a closer look at the need for a Wind Advisory
along our coastal zones for gusts of 46 miles per hour or greater for even a
brief time. We will be able to clarify these issues as 12z model
data arrives this morning. The main change presently is to bump
up temperatures in the early and middle afternoon.

&&

Short term /Wednesday through Thursday night/...
as of 3 am Tuesday...impressive low level thermal trough swinging
into the Carolinas on Wednesday and also decreasing in amplitude.
Looks like the coldest 850mb temperatures thus achieved at 18z before some
slight moderation. This temperature recovery will occur over the top
of the 3kft keep boundary layer though and forecast soundings as well as
MOS guidance show a frightfully cold afternoon with highs in the low
30s north to upper 30s south. Some cirrus level moisture increasing
Wednesday night should prevent ideal rad cooling but the airmass
will still support low temperatures within a few degrees of 20 for
Wednesday night lows. Thursday brings an exit of the first shortwave
and an approach from the north-northwest of the next one...as well as the next
cold shot. Ahead of these features Thursday afternoon will moderate
into the middle 40s...still over 10 degrees shy of climatology. The cold air
that follows will be more severe than that of Wednesday and Thursday
night lows should plunge solidly into the teens.

We definitely need to watch for thundersnow later. Whoever gets in some heavier bands might have a shot at it.

HRRR looks good for Eastern NC. Not sure what it was doing earlier.

I would be surprised if someone in NC doesn't see thundersnow today.

I guess I'm old fashioned again. I still listen for thundersnow. Who knew?

There's actually decent agreement between the short-range models on this death band. The HRRR gives me like 4" or something. Maybe it'll happen, though at best it's probably more like an inch or maybe two.

How about we look for lightning snow? :)
