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 local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Feb 18, 9:33 PM EST, 2 hours 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
933 PM EST SAT FEB 18 2012

.UPDATE...
A MESO-LOW WAS NOTED ON THE SQUALL LINE OVER SOUTHWEST GEORGIA AND
HAVE TRACKED THIS FEATURE ALL EVENING ACROSS LOWER ALABAMA.AS THIS
MESO-LOW SEEMS TO BE HELPING TO ENHANCE THE CONVECTION LOOKS LIKE
THERE IS A GOOD CHANCE IT WILL HOLD TOGETHER AS IT MOVES INTO THE
INTERIOR PORTIONS OF SOUTHEAST GEORGIA DESPITE MORE STABLE AIR
OVER OUR AREA. THUS THE TORNADO WATCH WAS ISSUED FOR THE AREA.
RIGHT NOW LOOKS LIKE WIND GUSTS TO AROUND 70 MPH ARE THE PRIMARY
THREAT BUT SOME ISOLATED TORNADOES ARE POSSIBLE. GIVEN THE SUPPORT
OF THE MESO-LOW FEATURE WOULDN'T BE SURPRISED IF A LONG TRACKED (AT
LEAST RELATIVE TO OUR AREA) TOUCHDOWN OCCURRED OVERNIGHT. SO FAR
MOST OF THE REPORTS FROM THE TALLAHASSEE AREA OR RESPONSIBILITY HAVE
BEEN FROM WIND DAMAGE AND LOCALIZED FLOODING.

AFTER THAT THE SEVERE THREAT WE SHOULD SEE A LITTLE BREAK UNTIL
THE MAIN LOW DEVELOPS OVER THE MOUTH OF THE MISSISSIPPI AND MOVES
INTO CENTRAL ALABAMA-GEORGIA. THAT WILL DRAG A COLD FRONT ACROSS
THE AREA ON SUNDAY. TIMING LOOKS LIKE EARLY TO MID MORNING FOR
INTERIOR SOUTHEAST GEORGIA AND THE SUWANNEE VALLEY AND THEN LATER
MORNING TO AFTERNOON FOR THE COAST AND REST OF NORTH FLORIDA.

&&

.AVIATION...
OTHER THAN THE SQUALL LINE TIMING WITH THE 850 MB TROUGH HANGING
BACK AND A SECONDARY TROUGH MOVING ACROSS THE AREA TOMORROW LOW
CEILINGS ARE GOING TO BE AN ISSUE THROUGH SUNSET ALONG WITH SOME
LOW LEVEL WIND SHEAR.

&&

.MARINE...
A WARM FRONT WILL LIFT NORTH OF THE REGION TONIGHT...FOLLOWED BY A
STRONG FRONTAL PASSAGE ON SUNDAY. THIS COLD FRONT WILL BRING A
ROUND OF SHOWERS AND STORMS WITH IT...FOLLOWED BY INCREASING WIND
SPEEDS. SMALL CRAFT ADVISORY WINDS ARE EXPECTED FOR SUNDAY
AFTERNOON THROUGH MONDAY MORNING. A PERIOD OF GALE FORCE GUSTS MAY
BE POSSIBLE OVER THE OFFSHORE WATERS SUNDAY NIGHT.

HIGH PRESSURE WILL THEN BUILD IN FOR THE FIRST PART OF THE WEEK.
A LOW PRESSURE SYSTEM WILL AFFECT THE REGION FOR MID
WEEK...FOLLOWED BY BUILDING HIGH PRESSURE TOWARD NEXT WEEKEND.
