AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 1241 PM CDT SAT JUN 19 2010 .UPDATE...18Z AVIATION DISCUSSION. && .DISCUSSION... SOME CHANGES TO THE FORECAST BASED ON CURRENT TRENDS. OBVIOUS OUTFLOW BOUNDARY FROM OVERNIGHT MCS CONTINUES TO PUSH SOUTHWARD...ALTHOUGH HAS DECELERATED SOMEWHAT OVER THE LAST FEW HOURS AS IT ENTERS THE TN VALLEY. AT THE SAME TIME...RUC AND NAM DEPICT A COMPLEX OF MID LEVEL SHORT WAVES ROUNDING THE APEX OF THE RIDGE AXIS. LEAD WAVE MAY BE THE MCV...BUT THE TRAILING MORE SUBSTANTIAL WAVE LOOKS TO BE ON THE SYNOPTIC SCALE. LOOKS LIKE THE ONSET OF STORMS SHOULD FIRE FIRST IN THE NORTH...THEN SHIFT SOUTHWARD THROUGH THE AFTERNOON AS FEATURES WITH PLENTY OF HEATING OUT AHEAD OF THESE FEATURES TODAY...ATMOSPHERE LOOKS TO BE ON THE VERGE OF POPPING...SUPPORTING A FAIRLY SUBSTANTIAL THREAT OF WET MICROBURSTS WITH ANY WELL DEVELOPED THUNDERSTORMS LATE THIS AFTERNOON AND INTO THE EVENING. WILL DO JUST A TAD MORE MESO- ANALYSIS BEFORE CHANGING THE EXTENT OF THE THREAT FOR THE AFTERNOON. JUST ISSUED MCD BY SPC SEEMS TO LEND SOME CREDENCE TO MY LINE OF THINKING. MAIN CHANGE TO THE FORECAST WAS TO INCREASE POPS ACROSS THE NORTHERN TIER OF COUNTIES...AND TO TEMPORALLY DELINEATE THE DEVELOPMENT OF THUNDERSTORMS FOR THE REMAINDER OF THE DAY BASED ON CURRENT TRENDS. ZONES ALREADY ON THE STREETS. STAY COOL AND HYDRATED TIL THE STORMS GET TO YOU... JD/02 && AVIATION...18Z TAF DISCUSSION. A LINE OF SHOWERS AND THUNDERSTORMS IS MOVING SOUTHEAST ACROSS THE NORTHERN PORTION OF THE FORECAST AREA EARLY THIS AFTERNOON. THIS LINE WILL CONTINUE TO TREK SOUTHEAST THROUGH THE REMAINDER OF THE AFTERNOON...AND COULD PRODUCE HEAVY RAINFALL...DAMAGING WINDS AND HAIL. TAF SITES MOST AFFECTED WILL BE TCL...BHM...EET AND ANB THIS AFTERNOON. THE LINE SHOULD WEAKEN BEFORE IT REACHES MGM AND TOI...BUT ISOLATED STORMS ARE POSSIBLE OUT AHEAD OF THE LINE...SO KEPT VCTS IN FOR THE SOUTH. ACTIVITY SHOULD DIMINISH OVERNIGHT...WITH WINDS BECOMING CALM AND SKIES CLEARING. NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO THE END OF THE FORECAST UNTIL FURTHER NOTICE WHILE CEILOMETER DATA IS BEING MONITORED FOR ACCURACY. ALSO...KTCL IS NOT REPORTING...SO HAVE INCLUDED AMEND NOT SKED FOR THIS SITE AS WELL. 19 && .BMX WATCHES/WARNINGS/ADVISORIES... NONE. && 88/19
