Pattern Jammin January 2023

Long range on the EPS does not look good, imo. The ridge is too far west, with a positive tilt that tucks the cold nicely in the west where it always wants to be. Atlantic ridge is large and in charge keeping the cold away.

Jet is starting to retract west of HI, like @griteater warned. Starting to think tropical forcing smacks us again. I'm pretty weary of a pattern change right now. ?

If I were were a betting man this is where my money would go. This has pretty much been the dominant pattern for years now. Maybe we get a few days or week of bona-fide cold (2014, 2015, Jan 18, Dec 22) but it never lasts more than that. The trough in the West or maybe central US with ridge in the East has been the rule of the land. The last sustained cold I can remember was Dec to early Jan 2010-11.

Or, another way to look at it is rather than persistence, the SE is overdue for a persistent stretch of wintry weather.

My money is on an initial central CONUS cold that finally spreads east behind a powerful App runner. Then we see if one or more suppressed systems can bring the goods with that persistent SW flow nearby. That said, I'd rather be in Mississippi, Alabama, or Tennessee rather than east of the mountains.

Wondering if that 10day euro storm is the app runner table setter.

Also not to go all hi res on you but 'Between' is really halfway "between" Monroe and Loganville as the map flies. :)

LOL. Yes, last year the mods were like where are you? And like an old Laurel and Hardy skit, I'd say between. ?

And yes, the EURO does hint at it and if somehow that was to verify at day ten, the next disturbance is teed up in the pacific NW it looks to me. Canadian has a similar solution too. The GFS, well it's the GFS beyond 72 hours.
 
Rah NWS is on board, giddy up! Lol

Dropping temperatures with the CAA will lower our overnight lows to
the upper 20s to low/middle 30s. The latest track of the upper-low
(good DPVA over eastern sections of central NC) would favor a
changeover from rain to snow late Fri night and early Sat, roughly
along/east of US-1, over the eastern Piedmont, Sandhills, and
central/southern Coastal Plain. Precipitation type nomograms and
forecast soundings show the thermal profile increasingly favoring
light snow or flurries by this time frame as the thicknesses (1000-
850 mb 1290m line and 850-700 mb 1540m contour) sag as far south and
east as the NC coast. The 12Z ECMWF has come in line with the
GFS/CMC/HREF as well. As a result, we added a chance of rain
changing to snow in this area late Fri night. Amounts are expected
to be light, roughly a trace to a dusting at best given above
freezing ground temperatures.
 
12z Euro - Only 10 days out!!! Mountain special..... We got time to work on temps east of the mountains.

CFS is showing a potential as well. Big difference is low position:

another tornado watch. I can't ever recall 2 tornado watches in January here.
 
KATL is currently sitting at +11.3F above the new January average thus far with the GFS forecasting below. This has essentially been March for all intense and purpose. Calculating these forecasted, temperatures KATL would be just a shade under +10 for the month, making a solid run at first, if not the second warmest January on record. Also, no lows at or below freezing, I'm sure that would be a first. At least we're getting plenty of rain.

Saw some trees inside Raleigh blooming . Thought it was only a UHI thing till I saw a tree in Zebulon blooming. Bradfords in Raleigh are bud heavy too.

A shot at getting to 32° this weekend. After that it’s smooth sailing through this month. With the potential for a more traditional Nina in February we may be in for a record stretch without a freeze.

Hard to tell if that is good trend or not really. Also offshore west coast storm looks better?

In the end it's probably rain for must of us but we are really lowering heights in the east and shifting the sfc low track SE. We'd need help from the D7 system to really go bonkers or something currently not modeled to sneak through in the fast northern stream type flow to establish marginal enough cold but it's worth keeping an eye on
 
Ya have to like the enhancement over northern Alabama and Georgia late afternoon and evening being depicted by the 00Z HRRR. Probably a little too warm in S. Carolina though.

It wouldn't surprise me one bit if some of these convective cells bring down some gusty winds and a few brief snow squalls especially in the higher elevations where it'll be quite windy.

00z HRRR continues to try and develop stuff over central and eastern NC .. it’s been developing some sort of banding feature over us and don’t really know what’s causing it? Any thoughts from some degreed mets? View attachment 130043
Not saying that this is a repeat, but this set up reminds me very much of this little system from February 2009. Models were picking up on the dynamics, but not the precip output until about 6 hours or so out. This basically fell from about 9pm to 3am overnight and surface temperatures were in the mid to upper 40s as precip started and just crashed to around freezing very quickly.

see those returns here in nw bama but history tells me that it will all be in northeast bama ,we barely ever get much out of this unless this setup is a little different
