Wintry 12/4-6 Winter Weather Potential

I can gurantee it won't happen. Snow will not be heavy enough for that. 4 max..
This aged really well. Heaviest snow actually fell around Blacksburg according to RadarScope reports (crazy to be in the bullseye). Rates were heavy enough it was just too little time for significant accumulation. Open wave in a fast jet streak!!

About 2 inches. It’s wet and adhering to everything. Not bad for early December. It zipped out of here pretty quickly.. I wasn’t awake for any heavy rates. Sounds like it was disappointing for NC folks, sorry yall. I’m 15 days post op and getting around in a knee scooter, so can’t measure or enjoy it with the same fervor as usual, but it’s pretty to look at
 
I never really bought the NC portion of this, it just seemed like a Virginia north storm (if you can even call it that). Getting appreciable snow in December is rare in NC/SC/Ga and we just hope the cold stays around in to January to have a legit chance for accumulating snow, as climo is optimal for us then
 
alright well i am a strong believer in forecasting transparency / public humiliation as motivation for getting things right next time, so here's my absolute stinker of a forecast map i made yesterday. just too aggressive, should have looked at QPF more & kuchera less and followed my gut on mixing cutting into totals more, but alas.

recap: some of the northwestern fringe (alleghany, surry counties, just north of mt. airy) of the 1-2" verified. most of Ashe/alleghany was in 2-4" and that was too high, i've seen one 2" report from the very tippy top nw corner of ashe this morning, so technically yay i guess. the 0.5-1" and dusting-0.5" placement was -ok- in WNC, but still too high generally as it seems accumulations above a half inch or so stop around boone. would have been a better map if i had trimmed the 1-2" further northwest (especially on the eastern end of the 1-2" zone) and dropped the 2-4" entirely. also, badly done for most of wilkes co. i think northern wilkes scraped out an inch, but that's all. 0.5 or less in town.

in my defense, i just got my degree 7 months ago and haven't been an operational forecaster for long, and the trends were late in the game on short-range modeling. but that's not really any excuse because my job as a meteorologist isn't to just blend what the models are saying at any given moment, its to predict where they end up

grade: D, maybe D+ if i am being generous. not terribly off in the NW corner of the state, but badly done in the foothills and north central part of the state. at least it looks nice.

If the super computers crunching billions of digits a run can't get it, why should you be expected to?

Regardless of what happened, I think this was still a good forecast with what you had to go by. It took climo into acocunt and you aren't just willy nilly posting click bait imagery to get traffic to your social media/news organization.

The only thing that made it wrong was a transient/shallow cold air source, imo

well, its extra frustrating because i either publicly pointed out fail modes or privately recognized them and still persisted with north central nc accumulations. i think by yesterday morning i should have been able to recognize things were moving north and adjusted those furtheast east zones. either way i like doing this and posting it so that i learn and improve beyond an ok forecast. anyone with NBM and a decent eye for mapping can make an ok forecast most of the time nowadays. need to work to make great forecasts.

experience, knowing biases etc, will go a long way

sucks we are losing the nam for the thermal profiles; i think it did okay, and even it was too cold vs reality
was weather next showing the same idea as your map?
