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, 2.3 hours before the alert went out and 91 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, Apr 8, 5:17 AM CDT, 4 hours 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
517 AM CDT SAT APR 8 2006

.SHORT TERM...(TODAY THROUGH MONDAY) MAIN EVENT WINDING DOWN
QUICKLY THIS MORNING...AND HOPEFULLY...WE ARE DONE WITH ALL THE
NASTY STUFF. SOME CONCERN THOUGH FOR LATER THIS MORNING...AS
LIGHTNING ACTIVITY IS PICKING UP WITH THE STORMS FORMING ALONG THE
COLD FRONT IN MISSISSIPPI. BASED ON CURRENT TRACK/SPEED...LOOKS
LIKE THE COLD FRONT WILL REACH MGM ABOUT 15Z. ACROSS SOUTHERN AND
SOUTHEASTERN PORTIONS OF THE FORECAST AREA...MAINLY ALONG THE U.S.
80/INTERSTATE 85 CORRIDOR EAST OF SELMA...SOME CONCERN WE MAY SEE
ANOTHER ROUND OF SEVERE THUNDERSTORMS. THE COMBINATION OF
MOIST/WARM AIR IN THE LOW LEVELS AND STEEPENING LAPSE RATES AS
TEMPERATURES COOL ALOFT SHOULD ALLOW FOR SUFFICIENT INSTABILITY TO
SUPPORT SOME ISOLATED STRONG TO MARGINALLY SEVERE STORMS...WITH
HAIL BEING THE MAIN CONCERN...AND PERHAPS WIND GUSTS.

OTHERWISE...TO THE NORTH AND WEST OF THIS AREA...WILL NEED TO KEEP
AT LEAST CHANCE POPS IN THE FORECAST...AS THE UPPER LEVEL SYSTEM
AND COLD POOL ALOFT PASS ACROSS THE AREA. WITH THE POSITIVELY
TILTED SYSTEM...THE DRIER AIR WILL BE SLOWER TO MOVE IN THAN
NORMAL...AND THE MOISTURE WILL STICK AROUND UNTIL THE PASSAGE OF
THE MID AND UPPER LEVEL TROUGH. TEMPERATURES ARE A BIT PROBLEMATIC
TODAY...WITH THE BEST/STRONGER COLD AIR ADVECTION NOT REALLY
KICKING IN UNTIL LATER THIS AFTERNOON. ON THE OTHER HAND...EXPECT
MOSTLY CLOUDY SKIES AT BEST FOR THE BULK OF THE DAY. WILL MOST
LIKELY MAKE SOME LAST MINUTE ADJUSTMENTS TO POPS AND TEMPS BASED
ON CURRENT TRENDS BEFORE 12Z.

BY TONIGHT...JUST A FEW LINGERING SHOWERS IN THE FAR SOUTHEAST
VERY EARLY IN THE EVENING...OTHERWISE WITH THE LOSS OF DAYTIME
HEATING AND FLOW OF DRIER AIR...CLOUDS SHOULD BEGIN TO CLEAR
FAIRLY QUICKLY FROM NORTHWEST TO SOUTHEAST. PRESSURE GRADIENT
LOOKS TO STAY FAIRLY TIGHT TONIGHT...SO EXPECT WINDS TO STAY UP
THROUGH THE NIGHT...AND KEEP US FROM COOLING TOO MUCH.

SUNDAY THROUGH MONDAY...MAINLY A TEMPERATURE FORECAST AS HIGH
SURFACE HIGH...SPRAWLING HIGH AT H8...AND H5 RIDGE CONTROL THE
WEATHER OVER THE SOUTHEAST. GUIDANCE TEMPERATURES ARE CLOSE...AND
TOOK A COMBINATION OF PERSISTENCE AND GUIDANCE BLEND.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY) WITH TROUGH DEEPENING
ALONG THE PACIFIC COAST...UPPER LEVEL RIDGING IS INDUCED AND
ENHANCED. TEMPERATURES WONT BE CLIMBING ALL TOO QUICKLY
HOWEVER...AS THE SURFACE HIGH AND H8 HIGH ARE ANCHORED ALONG THE
APPALACHIANS...AND WILL HOLD THE WARM AIR OFF TO OUR WEST.

EXTENDED FORECAST BASED SOLELY ON GFS/MAV GUIDANCE FOR THE 4 AM
ISSUANCE DUE TO WORKLOAD...AND WILL NEED TO MAKE SOME ADJUSTMENTS
AS MORE TIME IS AVAILABLE. ORIGINALLY INCLUDED SLIGHT CHANCE POPS
FOR SATURDAY...BUT AS MENTIONED IN PREEPD...GFS IS A BIT OF AN
OUTLIER AT THIS TIMEFRAME...BEING FASTER THAN OTHER SOLUTIONS.
WILL LIKELY TRIM THOSE POPS FURTHER AND REMOVE ANY MENTION OF
PRECIP FOR THAT PERIOD...AND REVISIT THE ENTIRE LONG TERM FOR
POSSIBLE TWEAKS BEFORE 12Z. WILL UPDATE AFD IF ANY MAJOR CHANGES
ARE REQUIRED.
