Area forecast discussion, Mar 29, 4:20 PM CDT, 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOBILE AL 420 PM CDT SAT MAR 29 2008 .SHORT TERM TONIGHT THROUGH MONDAY NIGHT...ONGOING SHOWERS AND THUNDERSTORMS LATE THIS AFTERNOON CONTINUE TO EXPAND IN COVERAGE AND INTENSITY. THESE SHOWERS AND STORMS HAVE DEVELOPED IN RESPONSE TO DECREASED STABILITY DUE TO BOUNDARY LAYER HEATING WITH SURFACE BASED CAPES AROUND 1200 J/KG AND ERODING MID LEVEL CAP AT AROUND 9KT FT. THE APPROACH OF A SLOW MOVING UPPER LEVEL SHORTWAVE (DISTURBANCE) IS ALSO PLAYING IN ROLE IN SUPPORTING DEEPER CONVECTION. THE SHOWERS AND STORMS WILL GRADUALLY DISSIPATE THROUGH THE EVENING HOURS AS THE SHORTWAVE MOVES EAST OF THE FORECAST AREA...AND DRIER AIR MOVES IN ON THE BACKSIDE. MEANWHILE THE SURFACE RIDGE EXTENDING FROM THE CAROLINAS SOUTHWEST INTO THE FORECAST AREA WILL REMAIN PERSISTENT THROUGH MONDAY NIGHT. THIS WILL MAINTAIN A SOUTHEAST WIND FLOW AT THE SURFACE...PROVIDING ENOUGH MOISTURE FOR PATCHY FOG TO FORM EACH NIGHT UNDER DRIER MID LAYER AIR. THE DRIER AIR ABOVE THE BOUNDARY LAYER HOWEVER WILL CUT BACK ON PRECIPITATION COVERAGE...SO SHOULD ONLY SEE A FEW ISOLATED (10%) AFTERNOON AND EVENING SHOWERS ON SUNDAY. UPPER RIDGE STRENGTHENS SLIGHTLY ON MONDAY...SO HAVE NOT MENTIONED ANY PRECIP AT THIS TIME. BUT MAY NEED TO ADD ISOLATED IF SEABREEZE DEVELOPMENT PROVIDES ENOUGH FORCING AND POOLING OF MOISTURE FOR CONVECTION TO POP. /22 && .LONG TERM TUESDAY THROUGH SATURDAY...MODELS INDICATE THAT ANOTHER FRONTAL BOUNDARY SHOULD BEGIN TO AFFECT THE AREA BY TUESDAY AS IT APPROACHES FROM THE WEST...THEN DRIFT VERY SLOWLY EAST ACROSS THE AREA WHILE GRADUALLY DISSIPATING THROUGH LATE WEDNESDAY. THIS WILL BRING ANOTHER CHANCE OF SHOWERS AND THUNDERSTORMS TO THE REGION DURING THE MIDDLE PART OF THE WEEK. KEPT A SLIGHT CHANCE OF RAIN THROUGH THE END OF THE WEEK...AS MODELS INDICATE YET ANOTHER FRONT POSSIBLE BY FRIDAY. RIGHT NOW JUST HAVE ISOLATED POP ON FRIDAY...BUT THIS MAY HAVE TO BE INCREASED TO CHANCE POPS ON LATER FCST PACKAGES. WITH THE FRONTAL BOUNDARIES MENTIONED HERE GENERALLY REMAINING NORTH OF THE FCST AREA...AND WITH OVERALL RIDGING CONTINUING...BASICALLY LOOKING FOR A CONTINUED EAST TO SOUTHEAST FLOW THROUGH THE PERIOD. THIS WILL RESULT IN A CONTINUATION OF MILD TEMPS...SLIGHTLY ABOVE NORMAL AT MOST LOCATIONS. /12 && .MARINE...WEAK HIGH PRESSURE OVER THE NORTH CENTRAL GULF WILL MOVE EAST THROUGH MONDAY AS A SURGE OF COOLER AIR MOVES SOUTHWARD OVER THE SOUTHEAST STATES. AS A RESULT EASTERLY WINDS AND SEAS WILL BUILD LATE SUNDAY NIGHT AND CONTINUE THROUGH MONDAY EVENING DUE TO A BETTER THERMAL GRADIENT NEAR THE COAST. A SMALL CRAFT ADVISORY MAY NEEDED FOR MONDAY FOR THE OFFSHORE WATERS. OTHERWISE...A LIGHT TO MODERATE SOUTHERLY WIND FLOW WILL CONTINUE THROUGH MUCH OF THE WEEK AS HIGH PRESSURE SETTLES ALONG MID ATLANTIC COAST. /32 && .FIRE...A DISSIPATING FRONTAL BOUNDARY ACROSS THE AREA WILL BRING A CHANCE OF SHOWERS AND A FEW THUNDERSTORMS THIS EVENING. DRIER CONDITIONS EXPECTED ON SUNDAY AND MONDAY AS HIGH PRESSURE BUILDS...BUT RAIN CHANCES WILL INCREASE ONCE AGAIN WITH THE NEXT FRONT ON TUESDAY AND WEDNESDAY. OTHERWISE...WITH THE ONSHORE FLOW CONTINUING...ATMOSPHERIC MOISTURE AND RH VALUES SHOULD BE WELL ABOVE CRITICAL LEVELS. EXPECT PATCHY LATE NIGHT AND EARLY MORNING FOG TO CONTINUE OVER THE NEXT COUPLE OF DAYS...DENSE IN SOME LOCATIONS. /22 && .PRELIMINARY POINT TEMPS/POPS...
