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.

.DISCUSSION...

AFTER SEVERAL DAYS OF MODEL DISCUSSIONS AND PREPAREDNESS
ACTIVITIES...THE SEVERE WEATHER EVENT IS NOW AT OUR DOORSTEP. AS
EXPECTED...THERE WAS A LULL IN THE CONVECTIVE ACTIVITY THIS
MORNING...BUT CONVECTION HAS INCREASED RAPIDLY THIS AFTERNOON DUE
TO DAYTIME HEATING. SURFACE TEMPERATURES HAVE ALREADY WARMED INTO
THE MIDDLE 70S ALONG AND SOUTH OF I-85. SURFACE BASED CAPES ARE
NOW OVER 1000 J/KG ACROSS SOUTH ALABAMA. 0-3KM STORM RELATIVE
HELICITY AND 0-6KM BULK SHEAR ARE STILL NOT HIGH ENOUGH FOR
AFTERNOON STORMS TO SHOW ANY DEEP UPDRAFTS OR ROTATION...BUT
THESE VALUES WILL INCREASE RAPIDLY THIS EVENING. THE MESO-SCALE
MODELS ARE SHOWING A BROKEN LINE OF CONVECTION AS THE BULK OF THE
ACTIVITY MOVES ACROSS CENTRAL ALABAMA. THE MAIN TAKE AWAY IS THAT
THERE WILL NOT BE A SOLID LINE OF STORMS THAT WILL BEGIN TO END
AND AT ONE LOCATION IN LESS THAN 30 MINUTES. THERE MAY BE SEVERAL
WAVES OF SEVERE STORMS THAT MOVE OVER ONE AREA. MODELS STILL
INDICATE THAT THE SEVERE THREAT WILL BE EAST OF CENTRAL ALABAMA BY
3 OR 4 AM. EVEN THROUGH THERE HAS BEEN A BREAK IN THE RAIN
TODAY...THE GROUND IS VERY MOIST AND ANY INTENSE RAINFALL COULD
LEAD TO LOCALIZED FLOODING.

COLDER AIR WILL SPREAD ACROSS CENTRAL ALABAMA ON WEDNESDAY EVEN
THOUGH SURFACE WINDS WILL NEVER BECOME NORTHWEST...LIKE AFTER A
TYPICAL FRONTAL PASSAGE. WEST WINDS WILL INCREASE DURING THE
MORNING HOURS WEDNESDAY TO BETWEEN 15 TO 25 MPH WITH GUSTS TO 35
MPH AT TIMES. THERE WILL BE A LARGE AREA OF WRAP AROUND MOISTURE
ON WEDNESDAY...SO THERE WILL BE VERY LIMITED SUNSHINE.
TEMPERATURES ACROSS NORTH ALABAMA WILL ACTUALLY FALL DURING THE
DAY WEDNESDAY. THE LOW CLOUDS MAY LINGER INTO WEDNESDAY
EVENING...BUT SOME CLEARING LIKELY FROM WEST TO EAST AFTER
MIDNIGHT. COLD AIR ADVECTION WILL CONTINUE INTO THURSDAY... BUT
MORE SUNSHINE EXPECTED ON THURSDAY. THE BRUNT OF THE COLD AIR MASS
SHIFTS EAST OF ALABAMA BY FRIDAY...BUT HIGHS WILL STILL BE 5-10
DEGREES BELOW AVERAGE. AN UPPER LEVEL SHORT WAVE TROF WILL PASS
THROUGH THE AREA ON SATURDAY...BUT AIR MASS TOO DRY FOR ANY
PRECIPITATION. A NICE WARM-UP OVER THE WEEKEND WITH HIGHS IN THE
60S AS AN UPPER RIDGE BUILDS OVER THE SOUTHEAST STATES. THE NEXT
CHANCE OF RAIN WILL BE LATE SUNDAY NIGHT AND MONDAY AS COLD FRONT
PASSES THROUGH ALABAMA.

58/ROSE

&&

.AVIATION...
00Z TAF DISCUSSION.

AREAS OF RAIN AND SHOWERS WILL AFFECT TERMINALS ACROSS CENTRAL
ALABAMA FOR THE NEXT 2-3HRS BEFORE STRONGER THUNDERSTORMS ARE
EXPECTED TO MOVE ACROSS THE AREA. THESE THUNDERSTORMS COULD PRODUCE
LARGE HAIL...TORNADOES...AND DAMAGING WINDS. OUTSIDE OF
CONVECTION...GRADIENT WINDS WILL BE STRONG WITH WIND GUSTS OF 25-
27KTS FROM THE SOUTHEAST BECOMING SOUTHWEST LATER TONIGHT. CIGS WILL
BE MVFR TO VFR.

AS THUNDERSTORMS EXIT...SCATTERED RAIN SHOWERS WILL BE POSSIBLE
THROUGH THE OVERNIGHT HOURS WITH MVFR CIGS AND FOG. WINDS WILL
REMAIN GUSTY.

.FIRE WEATHER...

HIGH RAIN CHANCES WILL CONTINUE THROUGH TONIGHT AS A STRONG STORM
SYSTEM MOVES THROUGH THE AREA. SEVERE STORMS ARE POSSIBLE TONIGHT.
MUCH COLDER AIR WILL IMPACT THE AREA WEDNESDAY AND THURSDAY.

WEDNESDAY NIGHT. DRY CONDITIONS THURSDAY THROUGH SUNDAY. NO
CRITICAL FIRE WEATHER CONCERNS EXPECTED.
