AREA FORECAST DISCUSSION...MESOSCALE UPDATE NATIONAL WEATHER SERVICE MOBILE AL 1247 PM CDT TUE JUN 15 2010 .AVIATION [15/18Z]...GENERALLY VFR CONDITIONS EXPECTED THROUGH THE PERIOD. AN ISOLATED SHOWERS OR THUNDERSTORM IS POSSIBLE DURING THE AFTERNOON WITH MVFR/IFR CONDITIONS POSSIBLE IN AND AROUND THE THUNDERSTORMS. SOUTHERLY WIND THIS AFTERNOON WILL BECOME LIGHT AND VARIABLE THIS EVENING AND OVERNIGHT. /22 .PREVIOUS DISCUSSIONS... .SHORT TERM...(TODAY AND TONIGHT)...THE UPPER RIDGE OVER THE EASTERN STATES WEAKENS SLIGHTLY THROUGH TONIGHT WHILE AN UPPER LOW WITHIN THE RIDGE SEEN OVER LOUISIANA IS ANTICIPATED TO MOVE SLOWLY NORTHWARD TO TENNESSEE. SOMEWHAT COOLER TEMPERATURES ALOFT ASSOCIATED WITH THE UPPER LOW RESULT IN HIGHER AFTERNOON SURFACE BASED CAPES AROUND 2500 J/KG OVER THE WESTERN PORTION OF THE FORECAST AREA WITH VALUES AROUND 2000 J/KG ELSEWHERE. THE SEA BREEZE WILL INITIATE CONVECTION BY LATE MORNING AND WILL HAVE CHANCE POPS ACROSS THE AREA...THEN MOSTLY INLAND DURING THE EVENING HOURS BEFORE THE CONVECTION ENDS. LIGHT STEERING WINDS AND CONTINUED HIGH DEEP LAYER MOISTURE AROUND 2.2 INCHES...THIS WILL RESULT IN HEAVY DOWNPOURS FROM CONVECTION FOR RELATIVELY SLOW MOVING STORMS WHICH MAY CAUSE LOCALIZED FLOODING OF AN URBAN OR LOW LYING AREA. ANOTHER HOT DAY IS IN STORE FOR THE AREA WITH HEAT INDICES OF 101-106. THE MICROBURST RISK FOR THIS AFTERNOON IS MODERATE. /29 .LONG TERM...(WEDNESDAY THROUGH MONDAY)...THE UPPER RIDGE WILL CONTINUE TO SHIFT EASTWARD AND WEAKEN AS A NORTHERN STREAM SHORTWAVE MOVES ACROSS THE OHIO VALLEY. THIS SYSTEM WILL SEND A WEAK COLD FRONT/SFC TROUGH SOUTHWARD TOWARD THE GULF COAST LATE WEDNESDAY INTO THURSDAY. THIS BOUNDARY ALONG WITH COOLER MID LEVEL TEMPS...PRECIPITABLE WATER VALUES AROUND 2 INCHES AND STRONG DAYTIME HEATING WILL SERVE TO IGNITE SCATTERED TO LOCALLY NUMEROUS SHOWERS AND THUNDERSTORMS EACH DAY THROUGH THE END OF THE WEEK. BETTER COVERAGES OF SHOWERS AND THUNDERSTORMS ALONG WITH THE ASSOCIATED CLOUDS WILL KEEP TEMPERATURES IN THE LOWER 90S. THESE THUNDERSTORMS WILL BE PULSE IN NATURE AND WITH STRONG INSTABILITY DURING PEAK AFTERNOON HEATING...CANNOT COMPLETELY RULE OUT A DAMAGING WIND GUST. HOWEVER...THE PRIMARY THREAT WILL BE FREQUENT CLOUD TO GROUND LIGHTNING AND LOCALLY HEAVY RAINFALL TOTALS AS THE THUNDERSTORMS WILL BE VERY EFFICIENT RAIN PRODUCERS WITH SLOW STORM MOTIONS. GLOBAL MODELS INDICATE THE UPPER RIDGE WILL REBUILD LATE IN THE WEEKEND INTO EARLY NEXT WEEK WITH RAIN CHANCES DECREASING SLIGHTLY. 13/JC && .AVIATION...(12Z ISSUANCE)...VFR CONDITIONS PREVAIL FOR THE NEXT 24 HOURS WITH A PROB30 GROUP FOR IFR CONDITIONS IN THUNDERSTORMS WITH VARIABLE AND GUSTY WINDS FROM 18-24Z. LIGHT AND VARIABLE WINDS THIS MORNING BECOME SOUTHERLY LATER THIS MORNING THEN LIGHT AND VARIABLE WINDS RETURN BY THIS EVENING. /29 && .MARINE...A SURFACE RIDGE OVER THE NORTHERN GULF SHIFTS SOUTHWARD THURSDAY INTO FRIDAY AS A WEAK TRAILING FRONT SETTLES INTO THE SOUTHEAST STATES. WINDS OVER THE MARINE AREA ARE LARGELY INFLUENCED BY THE LAND AND SEA BREEZE THROUGH WEDNESDAY NIGHT WITH WINDS BECOMING SOUTHWESTERLY DURING THE DAY THEN REVERSING TO A WEST TO NORTHWEST DIRECTION EACH NIGHT. WINDS BECOME WESTERLY THURSDAY AFTERNOON AS THE WEAK FRONTAL BOUNDARY MOVES TO NEAR THE COAST WITH A LIGHT WESTERLY FLOW CONTINUING THROUGH FRIDAY. AN ONSHORE FLOW BECOMES REESTABLISHED BY SATURDAY AFTERNOON AS THE FRONTAL BOUNDARY DISSIPATES. /29 && .PRELIMINARY POINT TEMPS/POPS...
