Wow! Flurries here at Otter Creek. Must have brought them back from Sugar Mountain. Could more be in store?

I'd say so... we are getting are typical evening enhancement here on the north side of Asheville... snow has picked up in intensity and now is accumulating on the ground and roads.

Current Observations:

Temperature: 20.3 degrees

Dewpoint: 16.8 degrees

Just to give you an idea of the evening snow band enhancement. Perhaps it coincided with the vort max from the shortwave moving through, but its kinda uncanny this happened right at sundown. Watch where the dewpoint jumps up.

There is something to that. I've told my wife a number of times over the years that the snow will pick up at sundown and it does. It was snowing really good for a while this evening. Very pretty to look at in the lights.

Well i didn't see any flakes the last few days but boy is it COLD. The wind is howling tonight and it's 24 already, wimdchills in the low teens. The high was 33.7 - ironically this is at least borderline "epic" cold for n ga in early dec (this would have been s very cold day even in mid Jan). At least my fear of the cold never gets here has been squashed (for now at least. Ask again in Jan or feb) :lol:

Oh I know man, you guys are incredibly overdue.

I agree. Western SC seems to miss out on a lot of events, no flood makers or training ever sets up there, winter storms managed to split around them, Summer thunderstorms are brief and far between, they're about the last place to expect wrap around snowshowers or anything from an incoming norhwest flow system system like a clipper. The heats the one thing that can get extreme. That whole state is really due for a good weather event.

You also forgot to add that during extreme cold events, we always wind up 4 to 6 degree's warmer than everyone else due to downsloping NW winds. Over the last 5 years, any day where Atlanta and/or Charlotte didn't get above freezing for a high, the Anderson/Clemson area would always top out at 40 degree's or more.

I turned 25 years old this October and I'm still waiting to experience my first snow storm greater than 4 inches.....just pitiful!!!

Second night in a row of this snow - and still no winter weather advisory anywhere in Buncombe County, even the Northern half of Buncombe. No surprise as I drove to work at 5:00AM that schools were closed in the county and city. Has the NWS GSP changed their policy about winter weather advisoriers? Why has one not been issued here in the past two days?

Yea thats the thermal belt that sets up across the metropolitan areas in Upstate, SC as well oftentimes during the night... keeping temperatures at times 5-10 degrees above even locations further south such as Columbia, SC.

Snowfall wise, I can only remember a few times where Upstate, SC was close to the theoretical jackpot. That was the March 1st, event 2009 where a swath of Greenville/Spartanburg and Cherokee counties got some of the highest totals during that event. Of course even in this event not the whole upstate was able to enjoy it, as the nice thermal eddy kept folks in Oconee and Pickens county in the rain for too long, and when it finally changed over the heaviest precipitation amounts were east of their area.

Another event that wasn't all that major but Upstate SC did benefit the most was the Feb 1st, 2007 event Where Oconee and Pickens got a good 2-4" of snowfall accumulation while areas north such as Asheville, NC barely managed a trace.

Of course February 26-27th was another great event for parts of the upstate... but again not everyone got to enjoy it, with the western Upstate mainly shafted.

Not so sure about that. I moved to places with snow - and lots of it - and still wanted more :lol:

There's been some oddball situations over the last decade that have left them out. A couple places that stand out in regards to the 30 year climo snow averages in the South, are Tennessee and western SC I think. Last years best potential on Jan 31 fell through for them and NC won again, against all guidance. Seems like all the overrunning events, few as they are, go to pot for one reason or another there, either convection robs, or a band develops in NC and dryslots them. Its happened a lot more in the last 10 years than I've ever noticed before. The best chances are with very weak waves in a southern stream, or just purely lucking up with the track of a very strong ULL, both of these seem rare nowadays.

Do you remember the 1/23/03 storm? Anderson/Clemson was the jackpot until that storm unfolded and ended up with rain most of the night. Unbelievably bad luck.

I remember it like it was yesterday. Rain wasn't the problem. We got about 3 hours of virga from 2 to 5am that morning and then a few flurries and that was it.

The initial precipitation coming from the Northwest was killed by the mountains. Then a lee side meso-low formed and I got to sit and watch that thing pivot a few miles to my East for about 8 hours and bury greenville/spartanburg/charlotte. Just thinking about that storm again makes me want to puke.

MJO and euro weeklies are what most LR forecasters use.

Anyone here have the time to explain (or share a link) how the MJO affects the STJ? I've been wondering for a while, but haven't been successful in researching it. I've been trying to improve my understanding of all the teleconnections, but about as far as I've gotten is loosely understanding the NAO, AO, and PNA. I want to learn!

That's the kind of attitude we love around here :thumbsup: .

The best thing I can tell you to do is follow Usedtobe and HM's posts about the MJO, you'll learn so much.
