Pattern January 2020 - Operation Thaw Alaska

Grain of salt and the usual but temps are in the low 40s when this is rolling through, if it could trend colder, who knows?

That 500mb pattern does not match the surface temps in the least...... something is off here.

There is WSW 500 mb flow and SW lower level flow ahead of an oncoming upper trough/cold front producing warmth in the E 1/3 of the US. Look at the surface isobars closely. Also, in NC, 850's are +4 to +6, which are ~3 C warmer than normal. Around RDU for example, the daily means late in this run are ~50 vs Feb 5th normals of 43.

If we can muddy the pattern up enough we might be able to get lucky. We have to have these occluding systems over the lakes/ne to supply these marginal air masses and to temporarily suppress the flow. If we catch a decently timed wave on the back end you might have something. I wouldn't bet the farm but its something to watch for
 
Update NCSNOW Greensboro last 42 days of winter forecast.

Off to a great start. As of midnight tonight GSO will be -3.5BN with 38 days to go. Really like our chances to get on the scoreboard as we head into the 2cnd week of February, Feb 6th time frame. Week 3 and 4 in Feb look very promising, but ill pass another week before cashing in on some encouraging model news. It looks like we will be shutout for the 2cnd January in a row. Odds are 95% + in that favor at the moment. Still think we are looking good to end the 42 day spell -1 BN and hit climo snowfall. Time will tell.
Todays all time record low occured on this date at GSO is -8. Also the biggest snow Ive personally witnessed in my county was Feb 28,2004 of 18 inches. All time record for the county is 26 inches from one storm. Bottom line it may not look like a royal flush on the models at H5, TC etc, but it aint over yet folks.

If I lived between charleston and myrtle I'd be glued to the radar right now with those returns only 40-50 miles away

I'm still wondering if a few showers will sneak into the FL coast from Daytona to Canaveral corridor later tonight just before the upper air gets too warm for snow. If so, with 850s below 0C and thicknesses below 540, I wonder if there could at least be a little snow mixed with the light rain? I know the surface will be above 32 near the coast. @pcbjr, are you going to chase this? ;)

Well that was interesting. 0z GFS 12z Thursday much more precip Georgia/Tennessee. Barely misses western NC when temps are below freezing. That frontal thump of rain wasn’t as impressive in prior runs,
 
Does appear to be a few flakes flying, certainly rare for coastal SC.

This is an equally brutal pattern we’re going to have to suffer through for at least the next 2 weeks. Stale cold. Highs in the lower 50’s and lows in the upper thirties/mid 40’s..unless we get something to close off and make its own cold air, I’m extremely doubtful it snows outside of the mountains..hopefully we can get the Pacific to play ball by February 101629134F-BFA3-4AA5-9B77-7CC40E66C364.png

This type of pattern would work better in March with ULLs
 
Cmc and GFS tonight showing a similar type of set up with plenty of time to change positions ... but definitely seems like a storm threat (rain or snow) depending on how much cold air we can wrap in

That's not that bad of a pattern to be honest, it's definitely not a torch pattern. I'd say the temps would be average for the most part (maybe slightly above or below average) for some area's depending on where you are located (factoring in mesoscale features.) I still think early February, the pattern may develop into a much more favorable pattern for below normal temps and active with storms across the Eastern US (including a good portion of the Southeastern US) The colder pattern could be long established, meaning a long duration of below normal temps through early February and possibly into mid February.

Can someone either agree or disagree that we should now be looking at the Canadian model and it’s ensembles with a more higher regard .. even vs Gfs now? In other words is the Canadian more trust worthy now in what it shows
 
Things could get real interesting early next week if this trend continues. Most models are slowly ticking northward w/ this system, we would need to see a pretty dramatic shift to give any of us a chance & of course also have enough cold air in place.

It would have to keep this trend up and get the tilt better. It's working on it, that's for sure.
