Impressive Squall Line heading towards Columbia, SC.

[Stormsfury]

Earlier this morning, the concerns were more towards the possibilities of FRZ precip, now it turns to the potential for severe weather ... already one severe thunderstorm warning has been issued for Northern Lexington County earlier tonight for the squall line ... dime size hail is expected ...

Other regions have experienced elevated convection, including an interesting tidbit from the GSP discussion tonight where lightning apparently struck very, very close to the WFO ...

Greenville, SC reported mix precip at 32º .. earlier they've reported freezing rain with thunderstorms ...

..GSP DISCUSSION...
HAVE SEEN SOME PRESSURE FALLS SINCE THIS AFTERNOON AND A GRADUAL
DECREASE OF THE SUB 32F WETBULB FIELD...BUT AS OF 01Z...IT STILL
DENOTES THE CURRENT ADVISORY AREA PRETTY WELL AND IS ABOUT 2-3 DEG
F COLDER THAN WHAT THE 18Z ETA PROGGED. WHERE RAIN HAS BEEN FALLING
FOR A WHILE...TEMPS HAVE PRETTY MUCH SETTLED IN AND WOULD EXPECT
LTL MOVEMENT EXCEPT POSSIBLY UPWARD A TAD THROUGH THE NIGHT.

WV IMAGERY INDICATES LEADING EDGE OF DRYING ALOFT BACK ACRS AL/GA
...BUT 88D LOOPS SHOW BACK EDGE OF CATEGORICAL CVRG OF WCB PCPN
ALREADY INTO WESTERN EDGE OF CWFA. BUT WITH NEG TILTED TROUGH STILL
UPSTREAM...LOOKS LIKE RETURNS HAVE STARTED TO FILL BACK IN. SO WILL
PROBABLY CONTINUE WITH CAT POPS EVEN FOR WESTERN SECTIONS BUT
OBVIOUSLY LESS ADDITIONAL QPF.

AS AN INTERESTING SIDEBAR...STG UVVS AND SOME ELEVATED INSTABILITY
HAVE RESULTED IN SOME THUNDER WITHIN CURRENT PCPN AREA...WITH AN
EARTH SHATTERING THUNDER CLAP NOTED HERE AT GSP WITHIN THE PAST HOUR.

CURRENT THUNDER LENDS CREDENCE TO THE ATMOSPHERE COOLING SOME THIS
EVENING AND ACRS NW NC...AN EROSION OF THE WARM NOSE PROBABLY WILL
OCCUR. THE COMBINATION OF OBSERVED 00Z GSO PARTIAL THICKNESS...MODEL
THICKNESS AND FCST SNDGS OVER THE NORTHERN MOUNTAINS & FTHLS SHOW A
POTENTIAL FOR A PERIOD OF FROZEN PCPN...BUT NOT CONCLUSIVELY COLD
ENOUGH...I.E. P-TYPE DETERMINATION OFF NOMOGRAMS AND BUFKIT
SNDGS...TO SAY THAT IT IS DEFINITE BUT CLOSE ENOUGH TO THROW A CHANCE
MIXED IN WITH PREDOMINATE FZRA.

ALL IN ALL...CURRENT ADVISORY AND WARNING LOOKS PRETTY GOOD. WITH
BACK EDGE OF HIGHEST REFLECTIVITY NOW JUST EAST OF ADVISORY AREA IN
MOUNTAINS...FEEL AREAS WEST OF ASHEVILLE DO NOT NEED TO BE UPGRADED.

GOING TO BE AN INTERESTING LATE EVENING PERIOD ACROSS THE NC FTHLS
AND N MTNS...IN HEART OF WARNING...WITH HIGHER REFLECTIVITIES POISED
TO ENTER THIS AREA SHORTLY.

LOOKS LIKE ACROSS THE UPSTATE AND NE GA HAS WETBULBED TO RIGHT
AROUND FREEZING AND WITH WEDGE MAINTENANCE DIMINISHING...LOOKS LIKE
SOME ADVISORY ICE STILL ON TRACK. EAST OF THE WARNING AREAS IN
NC...DWPTS HAVE BEEN RISING...BUT TEMPS STILL MILD. 01Z WETBULBS
CURRENTLY IN MID 30S...AND NOT CONFIDENT THAT ONCE PCPN BEGINS
IN EARNEST OVER THIS AREA THAT WE'LL SEE MUCH ICING GIVEN WEAKENING
WEDGE...BUT PROBABLY BEST TO HANG ONTO ADVISORY WITH MAIN THREAT
POSSIBLY SHIFTING TO JUST SOME LIGHT ICING ON ELEVATED SFCS.

I envy you!

South Carolina sure experiences some interesting weather in the winter. I have some relatives that recently relocated to southern Mississippi from Greenville, SC and they were complaining about how mild the winter was. I never realized they experienced so many winter precip events during the winter.

Wow those storms look intense! :o Stay safe tonight SF!
