AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 440 PM EDT SUN APR 12 2015 ...UNSETTLED WEATHER PATTERN WILL CONTINUE THROUGH THIS WEEK... .NEAR TERM /THROUGH MONDAY/... A WEAK FRONTAL BOUNDARY REMAINS DRAPED ALONG THE FL/GA BORDER. NUMEROUS TO WIDESPREAD SHOWERS AND ISOLATED TSTMS STREAM NORTH OF THE BOUNDARY ACROSS INTERIOR SE GA AS ANOTHER MID LEVEL SHORTWAVE RIDES ALONG THE SURFACE BOUNDARY. FURTHER SOUTH SEABREEZE/SMALL SCALE BOUNDARIES WILL INTERACT WITH THE NEARBY FRONTAL BOUNDARY THIS AFTN/EARLY EVENING RESULTING IN NUMEROUS SHOWERS/ISOLATED TSTMS. MOST OF THE ACTIVITY WILL DIMINISH AFTER SUNSET...WITH DRY CONDITIONS AREA WIDE AFTER MIDNIGHT. WITH LOW/MID DECK CLOUDS LIKELY PERSISTING...DO NOT EXPECT ORGANIZED DENSE FOG. ANOTHER WARM MUGGY NIGHT IN STORE WITH LOWS MAINLY IN THE MID/UPPER 60S. MONDAY...NO SIGNIFICANT CHANGE IN THE PATTERN...WITH THE FRONTAL BOUNDARY NUDGING NORTH INTO SE GA. THE FRONT...ALONG WITH CONTINUED MOIST FLOW AND AFTERNOON SEABREEZE INTERACTIONS WILL RESULT IN ANOTHER ROUND OF NUMEROUS SHOWERS AND SCATTERED TSTMS. NO ORGANIZED STRONG/SEVERE TSTMS EXPECTED. HIGHS IN THE LOWER TO MID 80S WILL PREVAIL. .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... DEEP SOUTHWEST FLOW WILL PREVAIL THROUGH THE SHORT TERM PERIOD...AS A SHORTWAVE EJECTS NORTHEASTWARD FROM THE DESERT SOUTHWEST INTO THE PLAINS STATES...WHILE ATLANTIC RIDGING BUILDS WESTWARD ACROSS THE FL PENINSULA. WEAK LOW PRESSURE WILL MOVE EAST/NORTHEASTWARD THROUGH THE TENNESSEE VALLEY ON MONDAY NIGHT AND TUESDAY ALONG A STALLED FRONTAL BOUNDARY. DIURNAL CONVECTION WILL WANE ACROSS NORTHEAST FL AND COASTAL SOUTHEAST GA ON MONDAY EVENING. WE LEFT WIDELY SCATTERED POPS IN THE FORECAST GRIDS THROUGH THE NIGHTTIME AND EARLY MORNING HOURS ON TUESDAY FOR INLAND SOUTHEAST GA...AS CONVECTION MAY LINGER WITH MESOSCALE BOUNDARIES POSSIBLY MOVING INTO THIS AREA FROM MORE WIDESPREAD ACTIVITY NEAR THE FRONTAL BOUNDARY. LOWS WILL REMAIN 10- 15 DEGREES ABOVE MID-APRIL CLIMO...WITH HUMID CONDITIONS AND CLOUDS KEEPING MINIMUMS IN THE 65-70 DEGREE RANGE. A PIECE OF SHORTWAVE ENERGY EMBEDDED IN THE SOUTHWEST FLOW ALOFT MAY DEVELOP MORNING CONVECTION OVER WESTERN PORTIONS OF OUR REGION ON TUESDAY. THIS ACTIVITY MAY BECOME WIDESPREAD AS IT MOVES TOWARDS COASTAL LOCATIONS DURING THE AFTERNOON HOURS. WARMER OFFSHORE FLOW SHOULD RESULT IN HIGHS REACHING THE 80S REGION-WIDE...BUT THIS IS HIGHLY DEPENDENT ON TIMING OF DIURNAL CONVECTIVE DEVELOPMENT. AS LOW PRESSURE MOVES OFFSHORE OF THE CAROLINAS ON TUESDAY EVENING...A FRONTAL BOUNDARY IS PROGGED TO SINK SOUTHWARD INTO SOUTHEAST GA. HOWEVER...SHORTWAVE ENERGY SHOULD DEPART OUR AREA...WITH DIURNAL ACTIVITY WANING BY EARLY EVENING AND ONLY ISOLATED POPS USED OVERNIGHT IN SOUTHEAST GA. LOWS WILL REMAIN IN THE 65-70 RANGE. A SIMILAR WEATHER PATTERN WILL PREVAIL FOR WEDNESDAY...AS SHORTWAVE ENERGY ADVECTS OVER OUR REGION AND A FRONTAL BOUNDARY STALLS OVER SOUTHEAST GA DUE TO SURFACE RIDGING WEDGING SOUTHWARD FROM THE MID- ATLANTIC STATES. WIDESPREAD MAINLY AFTERNOON AND EARLY EVENING CONVECTION IS EXPECTED...PERHAPS WITH A FOCUS ALONG INTERSTATE 95 AND THE ST. JOHNS RIVER BASIN AS DEVELOPING LOW-LEVEL E/SE FLOW PUSHES A SEA BREEZE INLAND. COASTAL HIGHS WILL LIKELY BE HELD TO THE MID/UPPER 70S DUE TO THE SEA BREEZE...WITH HIGHS INLAND GENERALLY 80- 85. ADDITIONAL SHORTWAVE ENERGY MAY CONTINUE TO IMPACT OUR REGION ON WEDNESDAY NIGHT...AND WE THUS LEFT SCATTERED POPS IN THE FORECAST GRIDS...EXCEPT NUMEROUS NEAR THE ALTAMAHA RIVER ALONG THE FRONTAL BOUNDARY. LOWS WILL REMAIN IN THE 60S. .LONG TERM /THURSDAY THROUGH SUNDAY/... A DEEP TROUGH WILL DROP SOUTHWARD FROM THE PACIFIC NORTHWEST INTO THE ROCKIES ON THURS...AND WILL THEN TURN EASTWARD THROUGH THE SOUTHERN PLAINS NEXT WEEKEND. THIS WEATHER PATTERN WILL KEEP A PERSISTENT AND MOIST WEST/SOUTHWEST FLOW PATTERN IN PLACE LOCALLY. MEANWHILE...A FRONTAL BOUNDARY WILL STALL OVER OUR REGION THURS...AND WILL THEN LIFT NORTHWARD AS A WARM FRONT FRI WELL IN ADVANCE OF AN APPROACHING COLD FRONT THAT IS PROGGED TO ENTER THE SOUTHEASTERN STATES BY SAT. THIS WILL KEEP A RATHER WET FORECAST IN PLACE...AS PERIODIC SHORTWAVE ENERGY MOVES ALONG THE NORTHERN GULF COAST AND CROSSES OUR REGION. TIMING THIS ENERGY THIS FAR IN ADVANCE IS DIFFICULT...AND WE WILL THUS USE A DIURNAL POP DISTRIBUTION IN THE FORECAST GRIDS...WITH SCATTERED TO NUMEROUS MAINLY AFTERNOON AND EVENING CONVECTION EXPECTED THURS WITH THE FRONTAL BOUNDARY NEARBY...AND SCATTERED COVERAGE FOR FRI AND SAT. LONG-TERM MODELS CONTINUE TO DISAGREE ON THE SPEED OF THE NEXT COLD FRONT THAT WILL BE APPROACHING OUR AREA LATE NEXT WEEKEND FROM THE WEST. WILL KEEP SCATTERED MAINLY DIURNAL-TYPE POPS IN PLACE FOR NEXT SUN UNTIL MORE CONSISTENCY IS REACHED IN THE LONG TERM MODEL SOLUTIONS. HIGHS WILL GENERALLY RANGE FROM THE MID/UPPER 70S OVER SOUTHEAST GA AND COASTAL LOCATIONS TO THE LOW/MID 80S OVER INLAND NORTHEAST AND NORTH CENTRAL FL THURS AND FRI...WARMING INTO THE 80S REGION-WIDE AHEAD OF THE APPROACHING FRONT NEXT WEEKEND. LOWS WILL REMAIN IN THE 60S. && .AVIATION... LOW END VFR/AREAS OF MVFR CAN BE EXPECTED THIS AFTN INTO EARLY EVENING WITH NUMEROUS SHOWERS AND ISOLATED TSTMS. WILL USE PREVAILING -SHRA FOR MOST SITES...WITH VCTS FOR THE TSTMS. ACTIVITY WILL DIMINISH THIS EVENING WITH VFR PREVAILING INTO THE OVERNIGHT. SOME LOW CLOUDS WILL BE POSSIBLE LATE OVERNIGHT INTO MONDAY MORNING...WITH MVFR LIKELY ESPECIALLY AT JAX/CRG/VQQ. && .MARINE...
