Wintry December 4-7 Winter Precip Chance

This is the first system of the year that legitimately has potential to produce some wintry weather around here given we're now well inside day 5.

Looks like the GFS, GFS parallel, ECMWF, CMC, & ICON are all hinting at the potential for at least some rain/snow showers Monday night east of the mountains.

The 0z ECMWF certainly wasn't shy about putting down some legit QPF east of the mountains & that's probably what it's gonna take in this kind of air mass to have any shot at snow. Hope we can amp up the s/w a little more and at least partially phase with the southern branch disturbance that'll come out of the southern plains to squeeze out a little more precip.

Any chance maybe Alabama could squeeze a few sprinkles out of this. Icon has been showing something light towards the gulf coast as well
 
It will be something for me to at least track while working night shifts this weekend. Ot overly optimistic at seeing a few flakes but just having a chance this early is nice.

also today is the 20th anniversary of the dec 3rd 2000 surprise crush job we got in eastern NC while areas west of I95 that were expecting a foot got flurries.

Sounds like the one time that the NW trend failed and did not deliver ! That’s rare these days .
 
Not that this means anything for my area and take a look at the increase on the Euro EPS 06z

I took a look back at the January 2018 surprise storm. While the look is somewhat similar, definitely much less room for the wave to mature this time around. A lot would have to change before somebody gets more than flurries.

Get the wave to tilt better and get a low to form is what we need. Again, similar look, but similarities don't show the whole story.gfs_z500_mslp_us_21.pngjanuary 2018.PNG

Yep overall trough axis needs to tilt more upright/neutral instead of being strongly positive/flat, that would slow the upper trough down and allow for more extensive QPF & potential for greater snow. It's a workable trend though being this is still ~4 ish days out.

Didn't the 2018 Januastorm show up relatively late on the models? I remember Brad P. saying a day before the storm the my area would receive 1-2 inches. I actually got around 6.

Yeah, I remember each NAM Run giving us higher, totals each time around. I recommend going through and looking through this thread:

I enjoy the fact that 1300 took the time to go back and delete all of their posts in that thread. Psycho much

Like you said, looks fairly similar just not looking as juicy. Which, I suppose could change. Something to note is that that thread was started 4 days out

I do think that with this setup it would be very difficult to get all of the board in play, even NC in play is questionable.

What do you think the chances we actually get accumulations outside the mountains are here? I'd have to imagine quite low
 
The last frame of the nam didn't look bad with more energy and a little farther west. I think it's still connected to initial system too much and will try to shear and stay positive tilt
 
Still looks good for the weekend system in the mountains for you snow chasers/uplope guys

Yeah I'm broke and have to work all the time, I need the goods to come to me.... not like those snow chasing high rollers.
