AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 258 PM EDT WED JUN 17 2009 ...ISOLATED SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON AND EVENING... ...HEAT ADVISORY CONDITIONS POSSIBLE FRIDAY AND SATURDAY... .SHORT TERM...TONIGHT THROUGH SATURDAY... LARGE RIDGE OF HIGH PRESSURE IN THE MID LEVELS OVER THE LOWER MS VALLEY WILL CONTINUE TO DRIFT EASTWARD INTO THE SOUTHEAST U.S. AND PUSH A WARM TONGUE OF AIR INTO THE FORECAST AREA. THIS WILL DRIVE MAX TEMPS INTO THE UPPER 90S TO LOWER 100S BY FRIDAY AND SATURDAY AND PUSH HEAT INDICES INTO THE 105 TO 110 RANGE WITH POSSIBLE HEAT ADVISORIES NEEDED BOTH DAYS...WITH THE RIDGE SUPPRESSING MOST OF THE TSTM ACTIVITY WITH ONLY ISOLD ACTIVITY POSSIBLE EACH DAY. THE NEXT 24 HOURS OF TRANSITION AS THE HIGH BUILDS TOWARD THE REGION IS A BIT MORE COMPLEX WITH COOL MID LEVEL TEMPS AND STEEP LAPSE RATES PROVIDING FOR ISOLD STRONG TO SVR TSTMS POSSIBLE ALONG THE ATLC COAST SBRZ AS IT MOVES INLAND AND COLLIDES WITH THE GOMEX SBRZ FRONT ALONG THE I-75 CORRIDOR THIS EVENING. DRIER AIR ALOFT WILL AID IN SVR TSTM DEVELOPMENT BUT WILL ALSO KEEP THE COVERAGE IN THE 20-30% RANGE THROUGH SUNSET. THE OTHER FORECAST PROBLEM IS THE POSSIBLE MCS DEVELOPMENT FURTHER UPSTREAM OVER THE MID ATLC STATES TONIGHT THAT COULD PUSH SOUTHWARD INTO THE FORECAST AREA LATE TONIGHT OR THAT THE LINGERING SHORTWAVE WILL PUSH ACRS THE FORECAST AREA ON THURSDAY AND AID IN TSTM DEVELOPMENT AND PROVIDE FOR A MORE SCATTERED COVERAGE BY LATE THU MORNING INTO THE AFTERNOON. THIS WILL KEEP MAX TEMPS ONCE AGAIN IN THE MID 90S BEFORE THE SURGE OF UPPER 90S/LOWER 100S ON FRI/SAT. .LONG TERM...SUNDAY THROUGH WEDNESDAY... HOT CONDITIONS WILL CONTINUE ON SUNDAY AND MONDAY AS RIDGE SLOWLY WEAKENS AND EASTERN U.S. TROF DEVELOPS THAT SHOULD PROVIDE A FRONTAL PASSAGE EITHER LATE MONDAY OR TUESDAY THAT WILL PROVIDE A SLIGHTLY COOLER...DRIER AND MORE STABLE AIRMASS WITH MAX TEMPERATURES COOLER TO MORE NORMAL VALUES AROUND 90 FOR THIS TIME OF YEAR. STILL SOME QUESTION AS TO HOW MUCH PCPN FALLS WITH THE FRONT BUT IT APPEARS AS THOUGH TSTM COVERAGE WILL REMAIN ISOLD TO SCATTERED THROUGH THE EXTENDED TIME FRAME WITH THE BEST CHANCES ALONG WITH THE FRONTAL PASSAGE. && .AVIATION...MOSTLY VFR CONDITIONS EXCEPT IN ISOLATED THUNDERSTORM ACTIVITY THIS EVENING.
