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 Jun 3, 12:47 PM CDT, 1 hour 20 minutes earlier.

Area forecast discussion, Jun 3, 12:47 PM CDT, 1 hour 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1247 PM CDT SUN JUN 3 2012

.UPDATE...
FOR AVIATION.

&&

.DISCUSSION...
CURRENTLY WATCHING A WEAK IMPULSE SLIDE THROUGH THE NORTHEAST THIS
MORNING. A FEW SHOWERS ARE CURRENTLY ASSOCIATED WITH THIS AND CLAP
OR TWO OF THUNDER CAN NOT BE RULED OUT ACROSS THE NORTH THROUGH
THE REST OF THE MORNING AND INTO THE AFTERNOON. WILL CONTINUE TO
WATCH THE DEVELOPING SHOWERS AND THUNDERSTORMS TO OUR NORTHWEST
AS THESE WILL MOVE INTO CENTRAL ALABAMA LATER THIS EVENING AND
INTO THE OVERNIGHT HOURS.

AS FOR THE UPDATE...RAISED POPS IN THE NORTHEAST TO CHANCE AND
ADJUSTED HOURLY TRENDS. THINKING THAT THE SOUTHERN SITES ARE GOOD
ON THE OVERALL TIMING OF THE TEMPERATURES WHILE THE NORTH WILL BE
TRENDING SLOWER DUE TO THE CLOUD COVER THIS MORNING. STILL THINK
THAT WE WILL WARM INTO THE MID TO EVEN UPPER 80S IN THE NORTH THIS
AFTERNOON...BUT HIGHS MAY BE A LITTLE LATER IN THE DAY. UPDATES
OUT ALREADY.

&&

.AVIATION...
18Z TAF DISCUSSION

VFR CONDITIONS ARE EXPECTED FOR THE MOST PART THROUGH THIS TAF CYCLE
WITH WNW WINDS AT 5-10 KTS.  THE MAIN THING WE WILL HAVE TO WATCH
THIS AFTERNOON AND TONIGHT WILL BE DEVELOPING THUNDERSTORMS.  UNDER
NORTHWESTERLY FLOW ALOFT THESE STORMS WILL BE DIFFICULT TO PIN DOWN
AS FAR AS TIMING...BUT STORMS ARE EXPECTED NONETHELESS...SOME OF
WHICH COULD BRING STRONG GUSTY WINDS.

HAVE DECIDED TO TRY TO TIME OUT AT THIS AFTERNOON CONVECTION AS WE
FINALLY HAVE SOME CONVECTION TO OUR WEST. TCL BHM AND EET WILL
LIKELY SEE THE FIRST IMPACT. STILL SOME UNCERTAINTIES ON THE EXTENT
OF THE COVERAGE WITH THE THUNDERSTORMS THIS AFTERNOON...BUT CHANCES
ARE HIGH ENOUGH NOW TO GO AHEAD AND INCLUDE TS FOR THIS AFTERNOON.

THE NEXT THUNDERSTORM IMPACTS WILL COME DURING THE EARLY MORNING
HOURS BEFORE 12Z. EXPECT THE MAJORITY OF THE WEATHER TO IMPACT BHM
AND TCL BEFORE 12Z THERE IS A CHANCE IT COULD WORK INTO TCL AND EET
FROM THE NORTH AS WELL. UNSURE ABOUT THE ENDING TIME SO WILL UPDATE
WITH THE EVENING FORECAST. CIGS AND VIS SHOULD BE REDUCED WITH ANY
STORMS THAT DEVELOP...SO PAY ATTENTION FOR THOSE AMENDMENTS AS WELL.
