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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
755 PM EDT FRI APR 15 2011

.PREV DISCUSSION... /ISSUED 352 PM EDT FRI APR 15 2011/

SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
SEVERE THUNDERSTORMS ONGOING TO OUR WEST THIS AFTERNOON AHEAD OF
A STRONG SURFACE COLD FRONT WHICH WAS JUST CROSSING THE MISSISSIPPI
RIVER. MODELS CONSISTENT IN DECREASING CAPE VALUES OVER GEORGIA
THIS EVENING...HOWEVER THE ATMOSPHERE IS STRONGLY SHEARED WITH A
LOW LEVEL JET IN EXCESS OF 50KT. A NORTHWARD MOVING WARM FRONT
SHOULD HELP DESTABILIZE THE AIR MASS THIS AFTERNOON AND EVENING
..AND THIS SHOULD SUPPORT STRONG TO A FEW SEVERE THUNDERSTORMS
ACROSS THE CWA. SEVERE THREAT SHOULD LAST OVERNIGHT AS THE STORMS
TRACK EASTWARD ACROSS THE CWA. MODELS SHOW RAPID DRYING ALOFT
SATURDAY...AND HAVE DECREASED POPS WEST TO EAST SATURDAY MORNING.
WINDS LOOK BORDERLINE FOR A WIND ADVISORY SATURDAY...BUT WILL LET
NEXT SHIFT TAKE ANOTHER LOOK. ONLY SHOWERS EASTERN ZONES DURING
SATURDAY AFTERNOON. WESTERLY FLOW ALOFT FOR REMAINDER OF THE SHORT
TERM WILL KEEP THE AREA DRY. WITH STRONG SOUTHERLY FLOW...HAVE
LEANED TOWARD THE WARMER OVERNIGHT LOWS. OTHERWISE A BLEND OF
MAV/MET LOOKS OKAY.

LONG TERM /MONDAY THROUGH FRIDAY/...
HAVE MADE NO CHANGES TO THE LONG TERM. UPPER FLOW IS MOSTLY ZONAL
THROUGH MID WEEK THEN BECOMES MORE SOUTHWEST. A FRONTAL BOUNDARY
SEEMS TO BECOME NEARLY STATIONARY TO OUR NORTH. WILL CONTINUE WITH
LOW CHANCE POPS TUESDAY THROUGH FRIDAY AS A COUPLE OF WAVES MOVE
ALONG THE FRONTAL BOUNDARY.

FIRE WEATHER...
/ISSUED 417 AM EDT FRI APR 15 2011/

&&

.AVIATION...
00Z UPDATE...
SHOWERS AND SEVERE THUNDERSTORMS ARE MOVING ACROSS THE AREA RIGHT
NOW. THESE THUNDERSTORMS WILL CONTINUE MOVING NORTH AND EAST
THROUGH LATE TONIGHT. ONCE THE COLD FRONT SWEEPS THROUGH TONIGHT
HIGH PRESSURE WILL BUILD IN WITH CLEAR SKIES EXPECTED BY 18Z SAT.
WINDS ARE OUT OF THE SE AND WILL SWING TO THE SW ONCE THE FRONT
MOVES THROUGH. THAT WILL BE AROUND 06Z-10Z SAT FOR THE ATL AREA.
CEILINGS SHOULD STAY IN THE VFR-MVFR RANGE THROUGH THE PERIOD. MAY
SEE SOME BRIEF PERIODS IF IFR CEILINGS IN AND AROUND TSRA
DEVELOPMENT. SAME GOES FOR THE VISIBILITIES AS WELL.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.

.DAY ONE...THIS AFTERNOON AND TONIGHT
SCATTERED SEVERE THUNDERSTORMS ARE EXPECTED ACROSS NORTH AND
CENTRAL GEORGIA THIS EVENING AND OVERNIGHT.

.SYNOPSIS...
A LOW PRESSURE SYSTEM WILL TRACK FROM THE CENTRAL PLAINS INTO THE
MIDWEST THIS AFTERNOON WHILE AN ASSOCIATED COLD FRONT TRAVERSES THE
SOUTHEAST TONIGHT.

.PRIMARY HAZARDS...
THE PRIMARY HAZARDS FROM THE THUNDERSTORMS WILL BE DAMAGING WIND
AND FREQUENT LIGHTNING. LARGE HAIL AND ISOLATED TORNADOES WILL
ALSO BE POSSIBLE. THE SEVERE WEATHER THREAT WILL ENTER NORTHWEST
GEORGIA AROUND 8 PM EDT AND CONTINUE ACROSS GEORGIA THROUGH THE
OVERNIGHT HOURS...EXITING CENTRAL GEORGIA LATE SATURDAY MORNING.

.DISCUSSION...
A STRONG COLD FRONT WILL PUSH ACROSS THE SOUTHEAST TONIGHT. AHEAD
OF THE SYSTEM...STRONG SOUTHERLY WINDS WILL SUPPLY A
WARM...MOIST...AND MODERATELY UNSTABLE AIRMASS TO THE AREA.
CAPE VALUES OF 500-1500 J/KG AND LIFTED INDEX VALUES OF -1 TO -3 WILL
BE SUFFICIENT FOR WIDESPREAD THUNDERSTORM DEVELOPMENT ALONG AND
AHEAD OF THE COLD FRONT. DEEP LAYER SHEAR AND STRONG UPPER LEVEL
SUPPORT WILL ALLOW FOR SOME STORMS TO BECOME SEVERE. ALTHOUGH
ISOLATED SUPERCELLS WILL BE POSSIBLE AHEAD OF THE MAIN SQUALL
LINE...THE MAIN THREAT WILL BE THE DAMAGING WIND ASSOCIATED WITH THE
SQUALL LINE.

.OTHER HAZARDS...
WINDY CONDITIONS ARE EXPECTED ACROSS PORTIONS OF NORTH GEORGIA THIS
AFTERNOON...GENERALLY NORTH OF A LINE FROM CARROLLTON TO MARIETTA TO
HELEN. SEE THE WIND ADVISORY /NPWFFC/ FOR MORE DETAILS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

THURSDAY. NO HAZARDOUS WEATHER IS EXPECTED SUNDAY AND MONDAY.
