Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Jacksonville, FL (KJAX), launched 12:00Z, 1.4 hours before the alert went out and 193 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
645 AM EST MON NOV 24 2014

.UPDATE...
MADE A FEW ADJUSTMENTS TO THE POPS AND WEATHER ACROSS THE SOUTHERN

AND SOUTHEASTERN PORTIONS OF THE AREA. ADJUSTED CLOUDS A LITTLE AS
WELL.

.PREV DISCUSSION... /ISSUED 337 AM EST MON NOV 24 2014/

SHORT TERM /TODAY THROUGH TUESDAY/...
COLD FRONT SWEEPS ACROSS THE FORECAST AREA TODAY. INDICATIONS ARE
PASSAGE WILL BE GENERALLY DRY ACROSS THE MAJORITY OF THE AREA AND I
HAVE KEPT POPS CONFINED MAINLY TO SOUTHERN AND EASTERN PORTIONS OF
THE AREA WHERE BETTER MOISTURE AND MARGINAL INSTABILITY REMAIN. WILL
NEED TO KEEP AN EYE OUT FOR ANY SHOWERS ACROSS WESTERN PORTIONS
EARLY IN THE DAY ALONG AND AHEAD OF THE FRONT. ENOUGH INSTABILITY
ACROSS THE FAR SOUTH AND EAST TO INCLUDE A CHANCE OF THUNDER FOR
THIS AFTERNOON. SOME SHEAR IS PRESENT DUE TO STRONG MID-LEVEL WINDS
BUT IS GENERALLY UNIDIRECTIONAL AND SEVERE THUNDERSTORMS DO NOT
APPEAR LIKELY. FRONT STALLS OUT SOMEWHERE JUST SOUTH OF THE FORECAST
AREA TONIGHT AS THE UPPER-LEVEL TROUGH AXIS REMAINS WEST OF THE
REGION. MOISTURE RETURNS TUESDAY FROM THE SOUTH AS A STRONG SHORT
WAVE DIGS TO THE LOWER MISSISSIPPI VALLEY INDUCING FAIRLY RAPID
SURFACE LOW DEVELOPMENT IN THE NORTHERN GULF OF MEXICO. LOW MOVES
ACROSS THE FLORIDA PENINSULA TO THE SOUTHEAST ATLANTIC COASTAL
WATERS WHICH KEEPS THE BEST PRECIPITATION CHANCES SOUTH AND EAST OF
OUR AREA...BUT SCATTERED SHOWERS ARE EXPECTED TO SPREAD NORTHWARD
DURING THE DAY TUESDAY.

20

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
SURFACE LOW MOVING ACROSS FLORIDA AND UP THE COAST OF THE
CAROLINAS TUESDAY NIGHT AND WEDNESDAY. THIS WILL SPREAD SHOWERS
BACK TO THE NORTHWEST ACROSS MUCH OF THE FORECAST AREA WITH
HIGHEST POPS OVER EASTERN SECTIONS. THERE REMAINS THE POSSIBILITY
OF SOME MIX OF PRECIPITATION ACROSS NORTHEAST GA TUESDAY NIGHT.
WILL CONTINUE TO WATCH FOR THIS...HOWEVER NOT LOOKING FOR ANY
ACCUMULATIONS. MODEL THICKNESS VALUES VARY SOME OVER THIS AREA
TUESDAY NIGHT BUT FOR NOW SEEMS AS THOUGH THE CRITICAL THICKNESS
VALUES STAY WEST OF THE AREA. SHOWERS ENDING FROM THE WEST
WEDNESDAY AS THE SURFACE LOW MOVES UP THE ATLANTIC COAST. UPPER
FLOW BECOMING MORE NORTHWEST ON WEDNESDAY BUT GRADUALLY
TRANSITIONS TO ZONAL BY THE END OF THE PERIOD. DRY THURSDAY
THROUGH SATURDAY...BUT A FRONT GETS PUSHED INTO THE TN VALLEY ON
SUNDAY AND THERE MAY BE A SLIGHT CHANCE OF SHOWERS ACROSS THE FAR
NORTH.

AVIATION...
12Z UPDATE...

MAINLY MVFR CEILINGS ACROSS THE NORTHERN 2/3 OF THE AREA CURRENTLY.

LOWER VISIBILITIES BETWEEN 12Z AND 14Z AS WELL. SCATTERED SHOWERS
WILL PERSIST ACROSS THE FAR SOUTHERN PORTION OF THE FORECAST
AREA...BUT WILL STAY SOUTH OF THE TAF SITES. SOUTHWEST WINDS 6-10KT
