The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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

Tallahassee Rgnl, FL (KTLH), launched 12:00Z, 8.1 hours before the alert went out and 195 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, Jul 28, 12:14 PM CDT, 2 hours 53 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1214 PM CDT MON JUL 28 2014

.UPDATE...
FOR 18Z AVIATION.

&&

.DISCUSSION...

LETS PLAY...WHERE IS THE COLD FRONT THIS MORNING. CHECKING THE
WIND SHIFT LINE ONE COULD PLACE THE FRONT SOUTH OF THE SHELBY
COUNTY AIRPORT ALREADY. BASED ON SATELLITE...THE FRONT IS MOVING
THROUGH TUSCALOOSA...BIRMINGHAM...TO TALLADEGA. BASED ON
DEWPOINTS. THE FRONT IS STILL NORTH OF BIRMINGHAM AND TUSCALOOSA
AS DEWPOINTS ARE STILL IN THE 70S SOUTH OF HERE. NOW THE FINAL
THING...BASED ON DEWPOINT CHANGES...THE FRONT IS BETWEEN
BIRMINGHAM AND CALERA. SO WITH ALL OF THIS FACTORED INTO THE
EQUATION WE WILL GO WITH AN EFFECTIVE FRONT NEAR THE I-20 CORRIDOR
AND MOVING SOUTH. WITH THIS ANALYSIS REARRANGED POPS AND TRENDS
FOR THE AFTERNOON. REMOVED THE LIKELY POPS IN THE SOUTHEAST AS
SCATTERED SHOWERS/STORMS WOULD BE BETTER PHRASEOLOGY FOR THE
CHANCES THIS AFTERNOON. PLAN ON LEAVING THE SEVERE THREAT AS IS
WITH THE MAIN THREAT FROM DEMOPOLIS TO ALEXANDER CITY. STILL FEEL
AS THOUGH THE BEST CHANCES WILL BE SOUTH OF I-85 AS WE WORK INTO
THE PEAK HEATING OF THE AFTERNOON.

16

&&

.AVIATION...
18Z TAF DISCUSSION.

THE FRONT IS THROUGH THE NORTHERN TAFS...SO RAIN CHANCES HAVE BEEN
REMOVED. MGM AND TOI STILL HAVE A CHANCE AT SEEING AN ISOLATED
STORM THIS AFTERNOON SO WENT WITH VCTS WITH ONLY TEMPO LOW MVFR
CLOUDS FOR 2 HOURS. BEST STORM CHANCES WILL BE AFTER 20Z THROUGH
23Z. WITH ABSOLUTELY ZERO COVERAGE AT THE TIME OF TAF ISSUANCE I
DO NOT HAVE ENOUGH CONFIDENCE TO INCLUDE ANY TEMP TSRA AT THIS
TIME FOR MGM OR TOI. WILL AMEND AS NEEDED.

AS FOR TONIGHT...WINDS FINALLY CALM DOWN AFTER 6Z AND THERE IS AN
OUTSIDE CHANCE AT SEEING SOME PATCHY FOG DEVELOP. REALLY DEPENDS
ON HOW QUICKLY THE DRY AIR CAN WORK IN. NOT ENOUGH CONFIDENCE TO
INCLUDE AT THIS TIME.

.BMX WATCHES/WARNINGS/ADVISORIES...
