I caught a bit of the news tonight and it’s heartbreaking to see what our neighbors in Kentucky and the other states are going through. Kinda hard to root for a pattern change that would bring more misery to those poor people.  For once, I’d be happy to see above normal temps and no precipitation.  

I agree, would love cold and snow but for now am okay with warm and no rain.

It's the unusual warmth that's causing the severe weather & we need the rain.

If u want a gradual step down process to cold,

To prevent the severe storms...

I'm ok with that but,

We need cold so we can prevent these types of events in winter.

Prayers to all victims.

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 220 PM EST Wednesday...A weak cold front will continue to
cross the FA early Sun with little additional precip and maybe a bit
of light snow across the higher NC mtn peaks. Colder air will filter
in behind the front as a 1030 mb Can high over the Great Lakes
region is progged to advance east and ridge down east of the Apps.
This flow will bring near seasonal and below temps back to the
region thru the period. The coldest air looks to push in from the NE
Sun night into Mon, while the atmos remains quite dry.

By Mon night things begin to change as the op models generally agree
on a weak nrn GOM low developing in a split flow regime aloft, which
will increase moist flux into the area. The 12z GFS has backed off
on the timing and degree of QPF response Mon night thru Tue and yet
is still quicker and moister than the current ECMWF. Thus, PoPs have
been curtailed back Mon night and Tue to the lower chance range.
Anticipated precip amts were also lowered, which makes a difference
as far as possible p/type issues early Tue. For now, have a little
snow across the higher NC terrain and a quick period of light
snow/rain mix north of I-40 thru daybreak Tue. If the current drying
trends continues, these lowly amts and p/types could be overdone.
Yet, much uncertainty exists with this set-up and things could
actually go the other way with more of a wintry threat as we get
closer to the period.

I have a question. Do you think if we get that Greenland block that's more central to west based and mjo propagation, will we get into a colder regime east of the rockies? 

Im not Grit but if the Pacific doesn't ease up then there is going to be a tug of war with were the cold goes because the PNA is a formable beast currently.

I do in January, yes - better chance for -EPO/+PNA as the MJO slowly propagates out of the W Pacific (but any long range forecast is no more than a best guess)

Becoming pretty typical here to punt an entire winter month without a single threat. Onto January 

December has always been our 'dud' month. You can certainly have events but I wouldn't weigh losing this month as heavily as losing Jan or Feb. 

 

(and that's not just anecdotal- Eric Webb put together a really nice graphic a few weeks ago showing this)

Yeah I can remember growing up and always remembering winter really starting around Christmas or New Years.

MJO Forecast on today's Euro Monthly is about as good as we could hope for.  Not hanging out in 3-4-5 and not Usain Bolting from 7 to 3

Griteater, I go to dacula mjo to see different rmm projections of mjo from various models. Have u been there? It has (bc) ecmwf , and gefs among others.

I agree, we need or especially those folks need a pattern change, are we ever going to get cold?  I realize winter doesn't start until next week so trying to hold off for better or cold and snowy weather.  :snowwindow:

I'm actually really rooting for the west to stay troughy/stormy for a while. Don't know if everyone here has glimpsed at the snowpack levels for the west but they were really low. That region was teetering on the edge of crisis (and still in not great shape). I will gladly take a few weeks of warmth if it means the snowpack/reservoirs out west can get restored to healthier levels and we can enjoy a troughy pattern with better conscious.
