December 11th - 13th Observations

[NEGa]

Finally can report steady flurries!!

(and to lookout as well!) i think yall are two of the posters who hadnt seen anything until today

[sctvman]

I recorded a 30.7 in this last outbreak of cold here. 54.0 now, blue skies trying to break through. Lots of rain earlier in the morning and early this afternoon. If it gets below freezing tonight, those puddles will melt and become ice. That could be a huge threat here tomorrow morning.

Ditto that!

[strongwxnc]

[oconeexman]

Thanks guys and gals! Don't even have to strain to see them, can stay inside and watch for now!

[superjames1992]

Awesome shot ! I think I am one of the few NC posters east of the mountains who wants to bother opening this thread today LOL.

LOL.

45 and overcast here. Nice warmup this afternoon ahead of the front. Looks like temps will be crashing later on based on what you guys are experiencing upstream. The cold front looks like it's getting close.

RAH giving some hope to those north of 40 west of 85 (leaves me out)

AS THE MID-LEVEL COLD CORE (-30C) MOVES ACROSS THE AREA...MODELS ARE

ALIKE IN SHOWING SUFFICIENT DYNAMICAL COOLING AND MOISTENING IN THE

DENDRITIC GROWTH ZONE OF -10 TO -20C TO OVERCOME THE ONSET OF LOW

LEVEL DRY ADVECTION TO SUPPORT FLURRIES AND/OR SNOW SHOWERS ACROSS

NORTHERN THIRD... MAINLY ALONG AND NORTH OF THE I-40/85 CORRIDORS.

IR IMAGERY ALONG WITH UPSTREAM OBSERVATIONS DEFINITELY SHOWS

ADEQUATE MID-LEVEL MOISTURE SURGING SOUTHEAST IN THE COMMA HEAD

PRECIP BAND...WITH SNOW BEING REPORTED IN EASTERN TN/UPSTATE AL AND

UPSTATE GA...INCLUDING ATLANTA. SNOW COULD BEGIN IN THE WESTERN

PIEDMONT AS EARLY AS 6 TO 7 PM...WITH THE SNOW/PRECIP BAND SHIFTING

EAST ACROSS THE NORTHERN PIEDMONT AND NORTHERN COASTAL PLAIN BY 06

TO 09Z. MODEL AVERAGE QPF IS AROUND 0.03"...SO DO NOT EXPECT

SNOWFALL AMOUNTS TO BE HIGH ENOUGH OVER TO WARRANT AN

ADVISORY...BUT...AS IS ALWAYS THE CASE WITH SUCH A DYNAMIC AND

POWERFUL SYSTEM...A SMALL MESOSCALE COULD PRODUCE A VERY LOCALIZED

DUSTING ACROSS THE NORTHERN PIEDMONT. STRONG COLD ADVECTION

OVERNIGHT HAS 1000-850MB THICKNESSES CRASHING TO NEAR 1273M.

OVERNIGHT LOWS 25 TO 30.

[FoothillsNC]

Nashville is getting pounded, and all of eastern Tennessee is about to reap the benefits of the vortmax charging around the backside of the 5H system. Great setup for central and eastern Tenn the next several hours, looks like it will get into northeast Alabama and northern Ga as well, with steady moderate to heavy snow at times.

You can see the infrared spinning, perfect to nail Tennessee.

Could be. If only it could get another 60-70 miles south.

[sctvman]

It dropped from 47 to 43 in Augusta in the last five minutes. The front is coming through.

Foothills, know that we are worried about downslope in our Area, but with dynamics and southwest approach we may be able to squeeze sumthin'!

Yep. ZZZZZZZZZZZZZZZZZZZZZZzzzzzzzzzzzzzzzz.......

Super weenie question...by N GA do you mean the far northern fringe/mountains or will us folks in the lowlands north of 20 "reap the benefits" as well?

28 with snow flurries to add something to this thread.

any chance that makes it down to north atlanta burbs?

[QC_Halo]

Sleeting near Uptown Charlotte

very brief. just for a minute. stopped now.

I see sun.

[eyewall]

A little mini squall just about to go through here:

[Gastonwxman]

NWS is being a bit bold with their statement for my area:

Late Afternoon: A slight chance of rain showers before 5pm, then a slight chance of rain and snow showers. Partly sunny, with a high near 47. West wind around 10 mph, with gusts as high as 28 mph. Chance of precipitation is 20%.

Tonight: A slight chance of snow showers before 8pm. Mostly cloudy, with a low around 24. West wind around 9 mph, with gusts as high as 28 mph. Chance of precipitation is 20%.

Earlier they said a few flurries...

[FoothillsNC]

Foothills, know that we are worried about downslope in our Area, but with dynamics and southwest approach we may be able to squeeze sumthin'!

Looks like there will be some flakes making a quick escape either early tomorrow morning or midday in NC, could be about anywhere, and they won't last long at all.

Super weenie question...by N GA do you mean the far northern fringe/mountains or will us folks in the lowlands north of 20 "reap the benefits" as well?

28 with snow flurries to add something to this thread.

From that lift, nw GA would catch it more than anywhere south of there. But good snow showers continue all day in the rest of ATL area.

[Buddy]

Temperature is dropping about 1 degree every 15 minutes now. Down to 26.5. Light snow showers.

[DaculaWeather]

28 degrees even. DP is 18 and falling at 3.5 deg/hr. A few flurries, had a nice flizzard a little while ago, I got a video I'll upload later.

[DaculaWeather]

I'm still VERY impressed with this wrap around http://www.daculaweather.com/ridge_mid_south_master.php

[NEGa]

the snow intensity has really increased in the last couple of minutes, as well as the wind. its 27 and snowing sideways lol

I'm still VERY impressed with this wrap around http://www.daculaweather.com/ridge_mid_south_master.php

yes it is! and if it lifts out the right direction, ne ga and the upstate might not be downsloped

[strongwxnc]

Playing around with Aviary screen capture

But you can see the temps starting to drop.

41 here

[CAD_Wedge_NC]

Had a heavy sleet shower just pass through here. Started as light rain then turned to heavy sleet. Sun is back out now.

[Itunis]

Full fledged flizzard (or light snow I suppose you'd call it) again here. I'll make sure to take pics this time before it gets blown away, lol. There's actually some blowing snow on the street in front of my house right now...very cool.

[Buddy]

Liking this wrap around moisture even more, it seems to be strengthening, not shrinking:

Snowfall on west side of nashville from DOT WEBCAM:

[EmersonGA]

Were getting the best snow of the day here. If it keeps up we might get an actual dusting. If this came at night it would be better.

[audioguy3107]

.....If this came at night it would be better.

It does seem like all our winter events in the last couple of years have been during the middle of the afternoon. I guess with afternoon temps in the upper 20's right now though, beggars can't be choosers.
