What forecasters said that day

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.

NWS Birmingham, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 25, 2:46 AM CDT, 41 minutes earlier.

Area forecast discussion, Apr 25, 2:46 AM CDT, 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
246 AM CDT SAT APR 25 2015

.DISCUSSION...

SHORT DISCUSSION THIS MORNING TO ONLY HANDLE THE SHORT TERM.
LINE OF CONVECTION MOVING INTO WESTERN ALABAMA IS MOVING INTO A
SLIGHTLY MORE STABLE AIRMASS. DEWPOINTS IN WESTERN ALABAMA NEAR
THE STATE LINE JUST NOW REACHING THE LOWER 60S WITH A DROP OFF
INTO THE MID 50S AT TCL. SURFACE BASED CAPE STILL NON-EXISTENT
WITH MU CAPE BETWEEN 100 TO 250 J/KG. THE REALLY MOISTURE RICH AIR
IS STILL JUST TO THE SOUTHWEST OF THE CWA. SHEAR VALUES ARE
PLENTIFUL TO SUPPORT SEVERE WEATHER HOWEVER...WITH 0-1KM HELICITY
OF 450+ AND 0-6KM BULK SHEAR AROUND 70 KTS.

OVER THE NEXT 1 TO 3 HOURS...A VERY STRONG MID LEVEL
JET FROM THE SOUTHWEST IS FORECAST TO MOVE INTO WESTERN ALABAMA
BY THE HRRR. WE SHOULD SEE AN INCREASING IN PRECIPITABLE WATER
WITH DEWPOINTS RISING INTO THE MID AND UPPER 60S AND AN INCREASE
IN THE POTENTIAL FOR SURFACE BASED CONVECTION.

STILL A LOT OF UNCERTAINTY WITH THE POTENTIAL RE-DEVELOPMENT LATER
THIS AFTERNOON. LOOKS LIKE THERE MIGHT BE A SECONDARY MID LEVEL
SPEED MAX TO DEVELOP OVER THE CWA BY AFTERNOON. HI-RES MODELS DO
RESPOND WITH SOME REDEVELOPMENT IN THE AREA SO THE POTENTIAL FOR A
SECOND ROUND OF SEVERE WEATHER STILL POSSIBLE. WILL SEE HOW THE
CURRENT CONVECTION EVOLVES THROUGH THE EARLY TO MID MORNING AND
UPDATE LATER FOR ANY CHANGES.

88

&&

.AVIATION...
06Z TAF DISCUSSION.

HAVE TIMED OUT APPROACHING CLUSTERS OF THUNDERSTORMS ACROSS NORTHERN
TERMINALS...AFFECTING THOSE SITES FROM WEST TO EAST BEGINNING AT
06Z. AT MGM AND TOI...DO NOT EXPECT THIS FIRST ROUND OF CONVECTION
TO EXTEND FAR ENOUGH SOUTHWARD...BUT MVFR CIGS ARE EXPECTED TO
SPREAD ACROSS THE AREA BY 09Z. THIS FIRST WAVE OF CONVECTION IS
EXPECTED TO CONTINUE THROUGH THE EARLY MORNING HOURS...WHICH A LARGE
AMOUNT OF CERTAINTY CONCERNING REDEVELOPMENT DURING THE LATE MORNING
AND AFTERNOON. STORMS EARLY THIS MORNING WILL BE STRONG TO SEVERE
WITH DAMAGING WINDS AND HEAVY RAINFALL. THE POSSIBILITY OF
REDEVELOPMENT EXISTS AREAWIDE LATE SATURDAY MORNING THROUGH
AFTERNOON AND THIS ACTIVITY WILL LIKELY BE SEVERE.
