URGENT - IMMEDIATE BROADCAST REQUESTED TORNADO WATCH NUMBER 900 NWS STORM PREDICTION CENTER NORMAN OK 325 PM EST THU DEC 22 2011 THE NWS STORM PREDICTION CENTER HAS ISSUED A TORNADO WATCH FOR PORTIONS OF NORTHERN AND CENTRAL GEORGIA FAR WESTERN NORTH CAROLINA FAR NORTHWEST SOUTH CAROLINA FAR SOUTHEAST TENNESSEE EFFECTIVE THIS THURSDAY AFTERNOON AND EVENING FROM 325 PM UNTIL 1100 PM EST. TORNADOES...HAIL TO 0.5 INCH IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS. THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 80 STATUTE MILES EITHER SIDE OF A LINE FROM MACON GEORGIA TO 75 MILES NORTHEAST OF ROME GEORGIA. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU0).

LATEST SURFACE ANALYSIS INDICATES A CONCENTRATED ZONE OF PRESSURE FALLS ACROSS THE SRN APPALACHIANS WHICH WILL ENHANCE LOW-LEVEL MOISTURE FLUX AND AID IN LOW-LEVEL CONVERGENCE AND UPLIFT ALONG THE HIGHER TERRAIN. WIDESPREAD CLOUDS WILL CONTINUE TO LIMIT THE DEGREE OF INSTABILITY WITH MLCAPE OF LESS THAN 500 J/KG. HOWEVER...GIVEN THE STRENGTHENING FORCING FOR ASCENT AND STRONG LOW- AND DEEP-LAYER SHEAR...A CONTINUED RISK FOR A COUPLE TORNADOES AND DAMAGING WINDS WILL EXIST WITH TSTMS AS THEY MOVE ACROSS THE REGION. AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT TO 0.5 INCH. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 400.

NavarreDon Posted December 22, 2011 Share Posted December 22, 2011 GSP afternoon afd for severe. .NEAR TERM /THROUGH FRIDAY/... AT 230 PM...LATEST SFC ANALYSIS INDICATED THAT A STATIONARY FRONT WAS LOCATED ACROSS THE EAST FACING MTN SLOPES/FOOTHILLS OF THE CAROLINAS...EXTENDING SW TO A SFC LOW OVER THE MS/AL STATE LINE. RECENT W/V IMAGE SHOWS A DEEP TROF PASSING OVER THE SOUTHERN MISSISSIPPI RIVER VALLEY...WITH DEEP MOISTURE TRANSPORT OCCURRING EAST ACROSS THE DEEP SOUTH TO THE SOUTHERN APPALACHIAN REGION. PWS GENERALLY RUNNING GREATER THAN 1.25 INCHES...OR AROUND 200 PERCENT OF NORMAL. MODELS INDICATE THAT THE LOW WILL TRACK NE ALONG THE STALLED THE FRONT...WITH THE LOW CENTER EXPECTED TO FAVOR TN SIDE OF THE MTNS. THE CWA WILL REMAIN IN THE WARM SECTOR THROUGH THE EARLY EVENING HOURS...WITH TEMPS AND DWPTS EXPECTED TO RANGE IN THE L60S TO U50S. AS THE LOW APPROACHES...LLVL WIND FIELDS WILL STRENGTHEN...WITH THE H85 WINDS EXPECTED TO PEAK AROUND 50S KTS ACROSS THE CWA AROUND 0Z FRI. FORECAST SOUNDINGS INDICATE THAT 0-1 KM HELICITY WILL INCREASE TO 250 TO 275 M2/S2 ACROSS THE MTN AND FOOTHILL AREAS BETWEEN 21Z TO 0Z...WITH HIGH VALUES CONTINUING THOUGH FROPA AROUND MIDNIGHT. WARM AND MOIST LLVL CONDITIONS ALONG WITH FALLING MID LEVEL HEIGHTS MAY SUPPORT A BROAD BAND OF 100 TO 600 J/KG OF CAPE ACROSS THE MTNS AND FOOTHILLS BETWEEN 21Z TO 3Z. IN ADDITION...QG FORCING WILL LIKELY PEAK ACROSS THE REGION AROUND 0Z. BASED ON THE TIMING OF THE FORCING AND SFC BASED FEATURES I EXPECT TWO ROUNDS OF SHRA. THE FIRST ROUND IS OCCURRING NOW WITH A WEST TO EAST BAND OF SHRA LIFTING NORTH ACROSS THE REGION. THIS BAND IS LIKELY RESPONDING TO AN INCREASE OF UPPER FORCING AND DEVELOPING LLVL INSTABILITY. THE SECOND ROUND WILL BE ASSOCIATED WITH THE BROAD AREA OF RA AND TSRA ASSOCIATED WITH THE SFC LOW AND COLD FRONT. THE COVERAGE ASSOCIATED WITH THE SECOND ROUND SHOULD ARRIVE OVER THE MTNS AND UPPER SAVANNAH RIVER VALLEY LATE THIS AFTERNOON...SWEEPING EAST WITH THE COLD FRONT MAINLY DURING THE MID EVENING HOURS...ENDING DURING THE EARLY MORNING HOURS. I WILL INCREASE POPS TO AROUND 100 PERCENT...WITH QPF RANGING FROM 1.5 OVER THE WESTERN MTNS TO HALF INCH EAST OF I-77. THE SEVERE POTENTIAL WILL INCREASE LATE THIS AFTERNOON ACROSS THE WESTERN NC MTNS TO THE UPPER SAVANNAH RIVER VALLEY AS CAPES DEVELOP AND LLVL SHEAR INCREASES. THE SEVERE THREAT WILL SHIFT EAST AS THE COLD FRONT MOVES ACROSS THE MTNS DURING THE MID EVENING HOURS. CAPE SHOULD BECOME VERY LIMITED AS THE FRONT APPROACH THE I-77 CORRIDOR. IT APPEARS THAT THE MOST LIKELY AREAS FOR SEVERE WEATHER WILL OCCUR ACROSS NE GA...THE UPSTATE OF SC...AND THE WESTERN NC MTNS DURING THE LATE AFTERNOON TO MID EVENING. THREATS WILL OCCUR WITH LINEAR CONVECTION...POSSIBLY PRODUCING SEVERE WIND GUSTS OR A BRIEF WEAK TORNADO. IN ADDITION...SATURATED SOIL...ELEVATED WATER LEVELS ON STREAM AND CREEKS...MAY YIELD A FASTER RESPONSE TO THE RAINFALL THROUGH THIS EVENING. IT IS POSSIBLE A COUPLE OF SPOTS ACROSS THE SOUTHERN APPALACHIANS COULD SEE STREAMS AND CREEKS APPROACH OR EXCEED BANKFULL. Link to comment Share on other sites More sharing options...

SouthernNJ Posted December 22, 2011 Share Posted December 22, 2011 A pair of mesocyclones heading toward the Troy AL area at this time. Neither super strong but worth watching closely. Also, a small but noticeable meso passed just northwest of Montgomery AL at about 245 PM CST. Was surprised at least an SVR was not issued there.

Heck, last year we were watching our white Christmas unfold on the models. The warmth has definitely held down the gas bill though. Link to comment Share on other sites More sharing options...

Lee Posted December 22, 2011 Share Posted December 22, 2011 A strong storm passed over here around 4:20. Wunderground Radar showed a Mesocyclone (C0) that briefly displayed a Tornado vortex sig. just as it moved to my NE. I noticed just as the storm was approaching that winds were from the ESE while the clouds were moving from the SW with some moving from the N within the dark cloud band( it looked like a squall line). Just before coming indoors, there were some what looked to be mamatus showing up within the middle portion of this dark line just to my west. Also, the hills just to my west were whited out from what appeared to be hail. I recorded just a little pea sized hail and very little rain with this. A peak gust of 42 mph was recorded as that line came through. According to Radar, the rotating cell went just to my north moving in a NE direction.

SouthernNJ Posted December 22, 2011 Share Posted December 22, 2011 The severe storm that passed through Rome took down some trees and has a little rotation with it as well. The rest of the line will, at the very least, maintain intensity as it bears down on Atlanta. Numerous embedded weak circulations mixed in.

audioguy3107 Posted December 22, 2011 Share Posted December 22, 2011 Looks to be a pretty good circulation persisting on the cell NE of Rome, GA. Still SVR warned, no TOR warning, but keep your heads up if you're in that neck of the woods. Link to comment Share on other sites More sharing options...
LithiaWx Posted December 22, 2011 Share Posted December 22, 2011 The most intense part of the line is about 10 minutes or so from my location. I'll report back with what I observed shortly. Link to comment Share on other sites More sharing options...
WeatherNC Posted December 22, 2011 Share Posted December 22, 2011 FFC still no L2 feed, using BMX, cell ssw of FFC is likely severe, moto posted a new dual pole hydro clas earlier, based on MHX's integration, within about 80-90 miles helpful, after that just clutter. Radarscope on iOS has dual pole graphics, L3 data feed, GRLX L2 has not updated, and wants several hundred more, kind of ticked and OT. Link to comment Share on other sites More sharing options...
DixieBlizzard Posted December 22, 2011 Share Posted December 22, 2011 Looks to be a pretty good circulation persisting on the cell NE of Rome, GA.

CandymanColumbusGA Posted December 22, 2011 Share Posted December 22, 2011 The Toomer's corner cam was AWESOME to have during the 5 when Auburn got slammed! Thankfully, this is more of a wind threat for us the rest of the way. There were some decent couplets earlier this afternoon but as soon as that second line of showers caught up to the first one, it squelched the tornadic threat. Let the rain and winds come!
