NWS Huntsville, AL wrote its last area forecast discussion before the first event at Aug 24, 9:06 AM CST, 3 hours 59 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1006 AM CDT FRI AUG 24 2007 .UPDATE... 12Z OHX AND NAM/GFS SOUNDINGS INDICATE THAT CONVECTIVE TEMPS SHOULD NOT BE REACHED UNTIL WE REACH 95 TO UPPER 90S RANGE BY THIS AFTERNOON. MESOETA/RUC MODELS ALSO INDICATE THAT BOUNDARY LAYER WINDS SHIFT AROUND IN SOUTHEAST AND EAST COUNTIES FROM NORTHEAST THIS AM TO SOUTHEAST BY AFTERNOON. ONCE THE WIND SHIFT TO THE SOUTHEAST OCCURS ALONG WITH AFTERNOON HEATING TO UPPER 90S/NEAR 100 DEGREE MARK...THESE FEATURES SHOULD COMBINE WITH TOPOGRAPHY IN EAST AND SOUTHEAST COUNTIES TO ALLOW FOR SOME AFTERNOON/EARLY EVENING WIDELY SCATTERED SHRA/TSRA DEVELOPMENT. DUE TO THE AMOUNT OF EXPECTED INSTABILITY...MOISTURE AND FORECAST WINDEX VALUES RANGING FROM 50-70 KTS ACROSS THE FA...WILL NOT RULE OUT POSSIBLITY OF ISOLATED STRONG TO SEVERE STORMS ESPECIALLY IN EAST AND SOUTHEAST COUNTIES. THIS WILL BEAR WATCHING AFTER 18Z AND INTO 00Z TIME FRAME. WILL CONTINUE WITH AT LEAST 20 POPS ESPECIALLY EAST OF I-65 THROUGH AFTERNOON AND INTO EARLY EVENING. AREAS WEST OF I-65 SHOULD BE LIMITED IN TSRA COVERAGE...THEREFORE WILL CONTINUE WITH ISOLATED POPS AND DRY FORECAST FOR FAR WESTERN COUNTIES. WILL ONLY BE MAKING A FEW CHANGES TO WORDING FOR AFTERNOON AND TO REMOVE MORNING WORDING IN CURRENT FORECAST. TEMPS ARE IN LINE WITH FORECAST AND WILL NOT BE MAKING ANY OTHER CHANGES. TROUTMAN && .PREV DISCUSSION... /ISSUED 355 AM CDT FRI AUG 24 2007/ DISCUSSION... UPPER RIDGING RULING THE GENERAL WEATHER SITUATION OVER MUCH OF THE SOUTHERN UNITED STATES WAS ON A DOWNWARD TREND...HEIGHTS WISE PER ANALYSIS OF 24/0000Z ANALYSIS. THE 500MB REFLECTION OF THE RIDGE WAS OVER THE REGION AT AROUND 595 DECAMETERS. THURS HIGH TEMPERATURES TOLD THE STORY PRETTY WELL...WITH NEARLY ALL OF OUR LOWER ELEVATED PLACES ABOVE 100F. DEEPER MOISTURE AND INSTABILITY TO WORK WITH ALLOWED SHOWERS/TSTORMS TO DEVELOP MOSTLY EAST AND SOUTH OF THIS REGION...WITH A LONE STORM MANAGING TO FORM OVER SOUTHERN DEKALB COUNTY THURSDAY AFTERNOON. FURTHER TO THE NW...NUMEROUS SHOWERS AND STORMS CONTINUED FROM NORTHERN NEW MEXICO TO THE UPPER MISSISSIPPI TO THE SOUTHERN GREAT LAKES. WARM 3 AM TEMPERATURES WERE NOTED... RANGING FROM 75 AT MUSCLE SHOALS TO 82 AT DECATUR. ALTHOUGH STRONG UPPER RIDGING WAS ON A WEAKENING TREND...ONE LAST DAY WITH HIGH TEMPERATURES WARMING TO THE CENTURY MARK APPEARS LIKELY FOR PARTS OF THE TENNESSEE VALLEY. YESTERDAYS HIGH OF 103F AT HUNTSVILLE WAS NOT ONLY A RECORD...IT ALSO MADE FOR 21 CONSECUTIVE DAYS THAT THE HIGH TEMPERATURES HAS WARMED TO OR ABOVE 95F...A NEW RECORD STREAK IN THAT REGARD. MUSCLE SHOALS AIRPORT RECORD OF 103 GAVE THEM A STRETCH OF 22 DAYS IN A ROW...PUTTING THEM IN 2ND PLACE FOR THIS STREAK. TODAYS FORECAST HIGH TEMPERATURE IS ALL BUT GUARANTEED TO TIE THEM FOR 1ST PLACE...AND ADD TO 1ST PLACE DAYS FOR HUNTSVILLE. SEE OUR PUBLIC INFORMATION STATEMENT...HUNPNSHUN OR NOUS44 KHUN FOR MORE INFORMATION. EVEN WITH TEMPERATURES A TAD COOLER THAN YESTERDAY...SLIGHT HIGHER DEWPOINTS FROM THE MORE FAVORED NGM/MAV MOS GUIDANCE WILL HELP PUSH HEAT INDICES INTO THE 103-107F RANGE...THIS MAY BE PESSIMISTIC. WILL UPDATE THE SPECIAL WEATHER STATEMENT WE HAVE ON THIS HEAT TO BE ISSUED SHORTLY AFTER THE FORECAST PACKAGE HAS BEEN SHIPPED. HIGHER DEWPOINTS AND STRONG HEATING WILL MAKE FOR A SLIGHT CHANCE FOR SHOWERS AND STORMS THIS AFTERNOON MAINLY OVER OUR EASTERN AREAS. SOUNDINGS FROM THE NAM SUGGEST THE STRONGER STORMS WILL BE CAPABLE OF PRODUCING STRONG GUSTY WINDS AND NEAR SEVERE HAIL. THERE WERE REPORTS OF HAIL UP TO GOLFBALL IN SIZE OVER NORTHERN GEORGIA THURS. FOR SATURDAY AND SUNDAY...WILL CONTINUE A SLIGHT CHANCE FOR SHOWERS AND THUNDERSTORMS AS MORE GULF MOISTURE AND INSTABILITY WORKS OVER THIS REGION. THE ADDITIONAL MOISTURE AND CLOUDINESS SHOULD PUSH HIGH TEMPERATURES DOWN FROM THE TOASTY READINGS OF LATE...TO THE MID 90S. HIGHER DEWPOINTS WILL KEEP HEAT INDICES NEAR 100. MONDAY THROUGH TUESDAY...SOMEWHAT DRIER AIR MOVING INTO THE REGION WILL MAKE FOR A DRY FORECAST. LOWER HEIGHTS WITH THE MAIN RIDGING BROADENING TO THE WEST WILL REDUCE HIGH TEMPS TO THE LOWER AND MID 90S. WEDNESDAY AND THURSDAY...WILL BRING A SLIGHT CHANCE OF RAIN FOR WEDNESDAY AS MORE MOISTURE ARRIVES AND A FRONT FROM THE NORTH NEARS THE REGION. STRANGELY...GFS MOS GUIDANCE DROPS POPS WITH THE FRONT NEARBY ON THURSDAY. HAVE DECIDED TO LEAVE A CHANCE IN AS IS...WILL LET THE DAY SHIFT FURTHER EVALUATE THIS WITH OUTPUT FROM THE ENSEMBLES AND THE 06Z/12Z MODEL RUNS. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
