...ACCUMULATING SNOW POSSIBLE ON SATURDAY...

AN UPPER LEVEL LOW WILL CROSS THE MOUNTAINS DURING THE DAY ON

SATURDAY. A BAND OF SNOW IS EXPECTED TO DEVELOP OVER THE

SOUTHWEST MOUNTAINS A LITTLE AFTER SUNRISE...AND THEN SPREAD

NORTHEAST ACROSS THE REST OF THE MOUNTAINS DURING THE MORNING

HOURS. SNOW IS EXPECTED TO DEVELOP OVER THE FOOTHILLS AROUND NOON.

UP TO AN INCH OF SNOW IS POSSIBLE ACROSS MUCH OF THIS

AREA. AS TEMPERATURES WILL FALL BELOW FREEZING ACROSS THE HIGH

TERRAIN TONIGHT...ROADS...PARTICULARLY BRIDGES AND

OVERPASSES...WILL QUICKLY BECOME SLICK AND TREACHEROUS ONCE THE

PRECIPITATION STARTS. THE SNOW SHOULD EXIT THE REGION BY LATE

AFTERNOON OR EARLY EVENIN

What are they looking at???? must be discounting the GFS and going off the NAM.

I"m ready to ditch this pattern. The block is in the wrong spot (for me). The clippers in nw flow can still manage central NC from 40 north and the mountains and west of Apps , but for this area its dead precip wise. I'd like to see a central US trough, not east coast one.

Yep, I am now of the opinion that a +PNA is significantly more important for us than a -NAO. It seems like the blocks w/o a decent pacific are only good for cold and no snow.:thumbsdown:

Sounds about right. Gotta love the computer generated calls.

depends on where the block is. If we could have got a southern stream going or a split flow in Pac, we'd be in business I think. But the southern stream is extremely weak this year. I haven't had much precip here since August, just a very dry pattern for most of the Upstate (east of you I think) to CLT region. Just baby precip events, followed by extreme cold. Last years pattern was almost perfect but was alittle too strong and headed north just when we thought we'd be safe. Those big snows in Va and DC were just a few miles off from being ours had we had blocking then. At any rate, the pattern is probably going to be about the same, snow chances in I-40 and north in NC, but nothing overwhelming with stuff coming east of the mountains, light precip events in the Upstate to here, followed by cold, repeat the whole pattern. Parts of NC could end up with their annual AVG soon in the northern Piedmont, maybe coastal areas before the end of the month.

does it seem to be moving faster?

Based on the 0z GFS 6hr QPF through 6z, I would say yes for that band in central AL, as well as the returns working through se AL and sw GA. Just mo looking at radar returns compared to what this model shows for 6hr QPF through 1am EST.

I am not on the map, not that it really matters at this point. :(

25 here in Greenville already.

Forecasted low verified, surprising considering our high today was 3F above the forecast. Keep it coming but we need to radiate into the lower 20's to have any hope, but even that will be easily offset with a stiff sw wind aloft come tomorrow.

Hey all, dont post much, just read alot.. lol probably too much. Just wanted to stop in from northwestern ( just north of RDU) Raleigh and say thanks to all you guys who explain everything so well so people like me can understand.

Also, Ill gladly take the 3-4" the nam and that map above give me.

Edit: shows as my first post, but im a transplant from eastern, been reading since last year :)

Latest RUC showing lots of precip over AL around 6am. 35dbz. Interesting. GFS showed nothing.

If the national mosaic looks anything close to that at 7 am, a lot of folks are going to be giddy about there chances. That image is not likely to verify given the current trends, especially through the TN Valley. But I could be wrong as my wife says, it happens from time to time...
