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

Birmingham, AL (KBMX), launched 12:00Z, 9.4 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, Jun 23, 4:00 PM CDT, 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
400 PM CDT FRI JUN 23 2006

.SHORT TERM (TONIGHT AND SATURDAY)...SCATTERED STRONG TO SEVERE
STORMS WILL GRADUALLY WEAKEN THROUGH THE MID EVENING HOURS.  LARGE
CAPES COMBINED WITH A SIGNIFICANT SURFACE TO FREEZING LEVEL LAPSE
RATE RESULTED IN LARGE HAIL PRODUCTION WITH SOME STORMS VERIFYING
WITH NICKEL TO GOLFBALL HAIL OVER THE COASTAL COUNTIES.  A VERY
SUPPORTIVE SUB-CLOUD PROFILE RESULTED IN SOME STORMS PRODUCING 50 KT
DOWNBURSTS AS WELL WITH SOME REPORTS OF DOWNED TREES.  BROOKLEY
FIELD IN MOBILE HAD A 52 KT WIND GUST IN THE EARLY AFTERNOON HOURS.
GIVEN THE LOSS OF DEEP INSOLATION...WEAKER CAPES AND A FAIR AMOUNT
OF MOISTURE BEING EJECTED INTO THE MID LAYERS AND THE PROFILES BEING
MODIFIED SOMEWHAT...THE COVERAGE OF SEVERE STORMS WILL LIKELY GO
DOWN INTO THE EARLY EVENING HOURS.  STILL...WE OPTED TO HIGHLIGHT A
FEW STORMS MAY BE SEVERE INTO THE EARLY EVENING HOURS FOR AREAS
ALONG AND WEST OF INTERSTATE 65.  AS FOR TOMORROW...EXPECT MORE
SCATTERED STORMS...AND A FEW COULD BE STRONG BUT NOT SURE WE WILL
SEE A CARBON COPY REPEAT OF TODAY.  /05

&&

.LONG TERM (SUNDAY THROUGH NEXT FRIDAY)...CONTINUED TO HIGHLIGHT
CHANCE POPS THROUGH SUNDAY ACROSS THE AREA GIVEN THE UPPER TROUGH
AMPLIFYING A BIT OVER THE SOUTHEASTERN STATES AND A WEAKENING
FRONTAL BOUNDARY SLIPPING SLOWLY DOWN TO JUST NORTH OF OUR AREA BY
SUNDAY.  ALSO...WE HAVE TO KEEP WATCH ON A WEAK AREA OF LOW
PRESSURE OVER THE BAHAMAS OVER THE NEXT FEW DAYS.  THIS FEATURE IS
FORECAST BY THE MODELS TO SLIDE A BIT FURTHER WEST AND THEY SHOW A
PATTERN SOMEWHAT CONDUCIVE FOR SLIGHT DEVELOPMENT.  HOWEVER...WITH
THE UPPER TROUGH SLIPPING ACROSS THE FORECAST AREA BY EARLY NEXT
WEEK AND A SOMEWHAT STRONGER SHORTWAVE DRIVING THROUGH THE BASE OF
THE TROUGH LATE MONDAY INTO TUESDAY...THE CHANCES ARE BETTER THAT IT
WILL GET PICKED UP AND MOVED NORTHEAST IF IT EVEN MAKES IT INTO THE
EASTERN GULFMEX EARLY NEXT WEEK.  WE CONTINUED WITH ANOTHER PATTERN
OF REDUCED RAIN CHANCES PAST NEXT MONDAY.  /05

&&

.MARINE...HIGH PRESSURE OVER THE SOUTHEAST STATES WILL WEAKEN AS A
WEAK LOW PRESSURE AREA APPROACHES THE REGION FROM FLORIDA BY EARLY
NEXT WEEK. AFTERNOON SEA BREEZE WILL BRING BRIEF ONSHORE WINDS NEAR
THE COAST.  SCATTERED STRONG THUNDERSTORMS WILL BE POSSIBLE NEAR
SHORE IN THE AFTERNOON HOURS.

&&

.FIRE WEATHER...SCATTERED THUNDERSTORMS WILL DIMINISH THIS
EVENING...WITH ADDITIONAL SCATTERED THUNDERSTORMS DEVELOPING
SATURDAY AFTERNOON AND AGAIN ON SUNDAY AS A WEAKENING FRONT STALLS
JUST TO THE NORTH.
