Area forecast discussion, Jul 31, 1:30 PM EST, 3 hours 26 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 230 PM EDT SUN JUL 31 2005 .SHORT TERM /TONIGHT THROUGH TUESDAY/... VERY LITTLE CHANGE IN WEATHER PARAMETERS DURING THIS PERIOD AS DEEP TROPICAL MOISTURE IS EXPECTED TO REMAIN ACROSS MOST IF NOT ALL OF MY FORECAST AREA. WEAK INVERTED TROF...THE REMAINS OF THE STALLED OUT BOUNDARY EXPECTED TO REMAIN ACROSS THE AREA AS WELL. ONLY WEAK AT BEST LARGE SCALE LIFT EXPECTED AS CONVECTION WILL BE DRIVEN BY LAND/SEA BREEZE AND NUMEROUS BOUNDARY INTERACTIONS. WILL CONTINUE WITH CONVECTION MAINLY OVER THE LAND AREAS FROM 16Z TO 04Z EACH DAY AND MAINLY OVER THE WATER AND IMMEDIATE COASTAL AREAS FROM 04Z TO 16Z EACH DAY. AS HAS BEEN THE CASE THE PAST FEW DAYS... LOCALLY HEAVY RAIN IS POSSIBLE WITH THE SLOW MOVING STORMS. SOME AREAS HAVE SEEN HEAVY RAIN THE PAST DAY OR SO...HOWEVER COVERAGE AREA IS NOT LARGE ENOUGH TO WARRANT A FLOOD WATCH AT THIS TIME. AT THE PRESENT TIME...MOST OF AREA IS CONVECTION FREE THANKS IN LARGE PART TO A LARGE COMPLEX THAT HAS DEVELOPED JUST TO THE NORTHEAST OF MY AREA. CONVECTION HAS DEVELOPED ALONG THE SEA BREEZE IN MY GEORGIA COUNTIES AND WITH DECENT HEATING OCCURRING IN MUCH OF THE REMAINDER OF MY CWA...THINKING IS THAT CONVECTION WILL INCREASE IN COVERAGE THIS EVENING ACROSS THE INLAND AREAS. SO WILL CONTINUE WITH LIKELY POPS OVER LAND AREAS UNTIL AROUND MIDNIGHT. RAISED POPS SOME MONDAY THROUGH TUESDAY AS GFS HOLDS ONTO DEEP MOISTURE THROUGH THE PERIOD AND NAM ONLY SLOWLY SHIFTS THE DEEPER MOISTURE SOUTHWARD. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... LARGE SCALE PATTERN IS NOT EXPECTED TO CHANGE DURING THIS PERIOD. WEAK INVERTED TROF/BOUNDARY EXPECTED TO BE AROUND THROUGH SUNDAY. ANY MOVEMENT TO THE DEEPER MOISTURE WILL BE KEY IN DETERMINING POPS. 00Z GFS...12Z CANADIAN AND 12Z NAM ALL SHIFT THE DEEPER MOISTURE SOUTH OF THE AREA BY MID WEEK. THIS FORECAST PACKAGE IS BASED ON THAT THINKING. HOWEVER...12Z GFS DOES NOT DO THAT AND KEEPS THE DEEP MOISTURE OVER THE AREA THROUGH SUNDAY. IF THE 12Z GFS IS CORRECT...POPS FOR THIS PERIOD WILL NEED TO BE RAISED SIGNIFICANTLY. && .MARINE...FEW CHANGES TO ONGOING THINKING. TRANQUIL CONDS...OUTSIDE OF CONVECTIVE ACTIVITY...TO REMAIN ACRS THE MARINE AREA THRU MIDWEEK. DISSIPATING FNTL BNDRY OFFSHORE TO BE REPLACED BY HIGH PRESSURE WHICH WILL ALLOW FOR A MORE SOLID ONSHORE FLOW. WIND SPEEDS TO REMAIN AOB 15 KT AND SEAS AOB 4 FT. && .AVIATION...LOCATION OF SHWR/TSTM ACTIVITY THE MAIN COMPLICATION AGAIN. FOCUS HAS SHIFT BACK TO KSAV THRU THE OPENING HRS OF THE 31/18Z TAFS WITH ACTIVITY ONGOING S AND W OF KSAV. WITH MAIN STORM MOTION TO THE N ALBEIT RATHER SLOW...HAVE HELD OFF PRECIP MENTION AT KSAV UNTIL 31/21Z. THINKING IS THAT GOOD HEATING WILL ALLOW MORE DEVELOPMENT LATER ON. HAVE REMOVED PRECIP FROM KCHS BECAUSE OF LACK OF CURRENT ACTIVITY AND UNCERTAINTY OF WHERE IT MAY OCCUR THRU THE EVE HRS. WILL MAINTAIN CB MENTION OVRNGT AT KCHS DUE TO XPCTD NOCTURNAL MARINE ACTIVITY THAT SHOULD MOVE N TWD THE COAST...AND OMITTED SUCH MENTION AT KSAV SINCE ACTIVITY USUALLY MISSES THERE. WILL AGAIN LOOK FOR CONVECTION STARTING LATE TMRW MRNG...AND HAVE AGAIN INCLUDED CB ONLY DUE TO UNCERTAINTY. && .CHS WATCHES/WARNINGS/ADVISORIES... SC...NONE. GA...NONE. MARINE...NONE. && MTE/JPC
