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 25, 3:41 PM CDT, 2 hours 44 minutes earlier.
Area forecast discussion, Jun 25, 3:41 PM CDT, 2 hours 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 341 PM CDT SAT JUN 25 2011 .DISCUSSION... CURRENTLY THIS AFTERNOON. A DECAYING MCS FEATURE IS PRESENT TO OUR NORTH. ACROSS THE SOUTHERN PART OF THE STATE CONVECTION IS POPPING UP WITH HEATING ALONG WHAT LOOKS TO BE THE LEFT OVER BOUNDARY FROM YESTERDAY'S STORMS. MODELS STRUGGLING PICKING UP ON AFTERNOON CONVECTION. PLACEMENT OF ACTIVITY IS DUE TO A SEVERAL FACTORS. ONE OF WHICH IS EXACT PLACEMENT OF THE DEVELOPING 500 MB RIDGE OVER THE SOUTHWEST U.S. INTO GULF SOUTH. MODELS PLACE ALABAMA IN NORTHERLY FLOW AROUND THE EASTERN EDGE OF THE HIGH WHICH WILL AIDE TRANSPORT OF MCS TYPE FEATURES TO SLIDE SOUTHWARD ACROSS THE STATE. THE MCS THIS MORNING HAS HAD DIFFICULTY MAKING PROGRESS INTO THE SOMEWHAT DRIER AIR ACROSS PORTIONS OF THE STATE. IR SATELLITE SHOWS CLOUD TOPS WARMING SIGNIFICANTLY AS THEY MOVE SOUTH. STORMS ACROSS THE SOUTH HAVE DONE THE BEST FOR 2 REASONS BECAUSE OF THE LINGERING BOUNDARY AND AMPLE LOW LEVEL GULF MOISTURE FEEDING NORTHWARD ONTO THE COAST AROUND THE ATLANTIC SURFACE HIGH. THIS LOW LEVEL FEED CONTINUES TO ASSIST SOMEWHAT THROUGH EARLY MONDAY WHEN THE ATLANTIC HIGH ELONGATES SOMEWHAT ACROSS THE GULF COAST WEAKLY. DURING THIS TIME THE 500 MB RIDGE SHIFTS FROM NEW MEXICO/WEST TEXAS TO OKLAHOMA/TEXAS THROUGH MID WEEK THEN BECOMES BROADER. WHAT ALL THIS MEANS FOR US IS ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE WEEK...POSSIBLY BETTER ACROSS THE EAST DEPENDING ON RIDGE PLACEMENT. TEMPERATURES WILL BE WARMING AS THE UPPER RIDGE BUILDS. REMEMBER THAT WILL ALLOW US TO HEAT UP GREATLY BEFORE CONVECTION LIKELY DEVELOPS FOR THE MOST PART. WILL NEED TO MONITOR HEAT INDEX VALUES AS WE MOVE INTO MID WEEK AS THE MEAGER MOISTURE ALONG WITH THE WARMER TEMPERATURES WILL MAKE US SNEAK CLOSER TO ADVISORY NUMBERS. NOT QUITE IN THE FORECAST NUMBERS AT THIS TIME BUT LITTLE CHANGES CAN MAKE A BIG DIFFERENCE. 08/MNK && .AVIATION...18Z TAF DISCUSSION. WILL BE IN A WAIT AND SEE MODE FOR THE FIRST FEW HOURS OF THE FORECAST...AS FAR AS SHOWER/THUNDERSTORM DEVELOPMENT GOES. BASED ON LATEST RADAR AND SATELLITE TRENDS...I WOULD SUSPECT THE BEST CHANCES FOR FORMATION WOULD BE IN EXTREME NORTH ALABAMA (MUCH LIKE YESTERDAY)...WITH EVENTUAL MOVEMENT INTO THE I-20/59 CORRIDOR. MY CONFIDENCE IN ANY SINGLE TAF SITE GETTING CEILING OR VISIBILITY RESTRICTIONS DUE TO RAIN IS PRETTY LOW AT THIS TIME...AND I HAVE OPTED TO NOT INCLUDE VCTS OR CB IN THE TAFS. UPDATES CAN BE MADE WITH AMPLE ENOUGH LEAD TIME WHEN/IF STORMS DO DEVELOP LATER IN THE FORECAST PERIOD. OTHERWISE...CONDITIONS WILL BE PREDOMINANTLY VFR...WITH CLOUD COVERAGE REMAINING BELOW 50 PERCENT. I GAVE ANB A COURTESY VISIBILITY RESTRICTION DUE TO BR OVERNIGHT...BASED ON THE PRIOR NIGHT'S FOG FORMATION THERE. LITTLE TO NONE EXPECTED ELSEWHERE... UNLESS THERE IS SUBSTANTIAL RAIN JUST BEFORE SUNSET. /61/ NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO THE END OF THE FORECAST UNTIL FURTHER NOTICE. THE CEILOMETER DATA WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY. && .PRELIMINARY POINT TEMPS/POPS...
