14What 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 Jul 3, 2:54 PM CDT, 59 minutes earlier.
Area forecast discussion, Jul 3, 2:54 PM CDT, 59 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 254 PM CDT SUN JUL 3 2011 .DISCUSSION... A TYPICAL SUMMER PATTERN WILL BE ON TAP FOR CENTRAL ALABAMA OVER THE NEXT 7 DAYS. NOW THAT A WEAK FRONTAL BOUNDARY HAS MOVED NORTH OF THE FORECAST AREA...EXPECT SCATTERED AFTERNOON AND EVENING STORMS THROUGH THE ENTIRE FORECAST PERIOD. IN ADDITION...THE INCREASE IN MOISTURE WILL HELP REGULATE TEMPERATURES KEEPING THEM FROM REACHING NEAR TRIPLE DIGITS. NEVER THE LESS...HEAT INDEX VALUES WILL STILL BE NEAR 100 WHEN FACTORING IN THE SURGE OF MOISTURE. MODELS HAVE BACKED AWAY FROM MOVING A FRONT ACROSS EARLY NEXT WEEK. IN FACT...YESTERDAY'S SOLUTION MIGHT HAVE BEEN THE ONLY ONE SHOWING THAT SOLUTION. THIS TIME OF THE YEAR...FRONTS LACK THE UPPER LEVEL SUPPORT THAT HELPS THEM REACH THE GULF OF MEXICO. WE COULD STILL SEE ANOTHER FRONT TRY TO COME IN TOWARDS THE END OF THE WEEK...BUT JUST LIKE THE PREVIOUS FRONT...IT COULD SUFFER THE SAME FATE AND NOT REACH THE AREA. SO WHAT DOES THIS MEAN FOR CENTRAL ALABAMA? THE COMBINATION OF LOW LEVEL MOISTURE AND LESS OF AN INFLUENCE BY THE UPPER LEVEL RIDGE...WILL PRODUCE PLENTY OF THUNDERSTORM ACTIVITY EACH AFTERNOON. MOST OF THE STORMS BEING TRIGGERED BY PEAK HEATING...THEN INCREASE IN NUMBERS BY COLLIDING OUTFLOW BOUNDARIES. FORECAST WISE...THE NAM CONTINUES TO PERFORM THE BEST OUT OF THE ALL THE GUIDANCE AND SEE NO REASON TO DEVIATE MUCH FROM IT. 10/ARM && .AVIATION...18Z TAF DISCUSSION. A SHALLOW SURFACE FRONT CURRENTLY SITUATED OVER CENTRAL ALABAMA WILL POSSIBLY AID IN CONVECTION THIS AFTERNOON. IT IS UNCLEAR EXACTLY WHAT SITES WILL BE AFFECTED BY THUNDERSTORMS...BUT IT LOOKS AS THOUGH THE SOUTHERN SITES HAVE A BETTER CHANCE THAN THE NORTHERN SITES. LEFT THE MENTION OF CB IN FOR BHM AND ANB AND VCTS FOR THE OTHER 4 SITES. WINDS WILL BECOME CALM SHORTLY AFTER SUNSET. ANY SITE THAT RECEIVES RAINFALL TODAY WILL LIKELY HAVE FOG IN THE MORNING. WENT AHEAD AND MENTIONED BR FOR ALL SITES SINCE MOISTURE TOMORROW MORNING LOOKS AS THOUGH IT WILL BE THE SAME AS THIS MORNING. 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. 73 && .PRELIMINARY POINT TEMPS/POPS...
