AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE BIRMINGHAM AL 342 PM CDT WED AUG 6 2008 ADDED MENTION OF POTENTIAL SEVERE WEATHER TOMORROW .DISCUSSION...FORECAST CHANGES ON THE HORIZON...SO IF YOURE TIRED OF THE HEAT AND HUMIDITY...HOLD TIGHT FOR ANOTHER DAY. OF COURSE...TO GET TO THAT SLIGHTLY COOLER AND DRIER AIR...WE ARE GOING TO HAVE TO PUSH A FRONT THROUGH HERE. ONE MORE LATE AFTERNOON/EVENING OF ISOLATED CONVECTION LEFT TO DEAL WITH TONIGHT. TOMORROW...THE FORECAST LOOKS ON TRACK...AND EXPECT A FAIRLY HEFTY SHORT WAVE AND COLD FRONT DURING THE AFTERNOON IN INCREASINGLY AMPLIFIED FLOW. SOME CONCERN WITH THE TIMING OF THIS SYSTEM COMING THROUGH DURING THE HEAT OF THE DAY...AS THE COMBINATION OF SURFACE INSTABILITY AND THE APPROACHING FRONT COULD RESULT IN STRONG TO SEVERE THUNDERSTORMS. MODELS IN GOOD AGREEMENT REMARKABLY PUSHING AN AUGUST COLD FRONT ALL THE WAY THROUGH THE FORECAST AREA AND TO THE COAST...ALTHOUGH THERE ARE SOME DIFFERENCES IN TIMING. BY THE END OF THE DAY FRIDAY...EXPECT THE FRONT TO BE STALLING ACROSS SOUTHERN ALABAMA. AS THE WEEKEND PROGRESSES...THE TROUGH WILL CONTINUE TO DEEPEN... AND THE SURFACE HIGH WILL SINK SOUTHWARD INTO THE OHIO VALLEY... EVENTUALLY INTO THE EASTERN TENNESSEE VALLEY BY MONDAY. SEASONABLY MILD...SLIGHTLY BELOW NORMAL...AND DRY CONDITIONS ARE EXPECTED ALL WEEKEND...WITH TEMPERATURES ACTUALLY COOLING DOWN INTO THE LOWER 60S FOR MORNING LOW TEMPS. AS THE HIGH MOVES OFF THE MID-ATLANTIC COAST TUESDAY...THE LEFTOVER FRONTAL BOUNDARY WILL BEGIN TO DRIFT NORTHWARD...WITH A GRADUAL RETURN OF LOW LEVEL MOISTURE FROM THE SOUTH. SOME QUESTION AS TO HOW FAST THIS BOUNDARY WILL RETURN... AND WHETHER SHORT WAVES IN THE LOWER AMPLITUDE NORTHWESTERLY FLOW WILL COMBINE FOR INCREASED RAIN CHANCES ON TUESDAY. EUROPEAN MODEL INTRODUCES A RATHER VIGOROUS SECOND FRONT IN THE FLOW TUESDAY NIGHT INTO WEDNESDAY...BUT WILL NOT QUITE BITE INTO THAT SOLUTION RIGHT NOW. JD/81 && .AVIATION...12Z TAF DISCUSSION. PREVAILING VFR CONDITIONS ARE EXPECTED OVER THE NEXT 24 HOURS. SCT CUMULUS DECK AROUND 4000 TO 5000 FEET THIS AFTERNOON.
