A FRONT WILL PUSH SLOWLY SOUTH THROUGH THE REGION TONIGHT...AND STALL OVER THE SAVANNAH RIVER AREA MONDAY...BEFORE SLOWLY PUSHING SOUTH OF THE REGION TUESDAY. ANOTHER FRONT WILL MOVE DOWN LATE WEEK. && .NEAR TERM /THROUGH TONIGHT/... FRONT/DEWPOINT GRADIENT APPEARS TO BE CURRENTLY STRETCHED ACROSS OUR FORECAST AREA (FA)...PUSHING FROM NE TO SW. DRIER AIR ENTERING THE NE FA...SO EXPECTING AFTERNOON AND EVENING CONVECTION TO BE MAINLY CONFINED TO THE W/SW FA. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... LATEST MODEL RUNS TRENDING TOWARDS STALLING THE FRONT ALONG THE SAVANNAH RIVER MONDAY...WHICH MAY MAKE SENSE CONSIDERING FRONT MAY BE GENERALLY PARALLEL TO A WEAK NW UPPER FLOW...SO IT WONT GET MUCH OF A PUSH EXCEPT FROM THE SURFACE HIGH BUILDING DOWN INTO THE MID ATLANTIC. THE 12Z MAV AND MET MOS POPS TRENDING UPWARDS...AND ARE NOW IN THE LIKELY CATEGORY FOR MONDAY/MONDAY NT ALONG THE CSRA....AND CHANCE CATEGORY CENTRAL FA. CURRENT FORECAST CONTAINS RELATIVELY LOW POPS FOR THAT AREA AND TIME FRAME. WILL NOT MAKE RADICAL CHANGES AT THIS TIME...BUT AFTER COORDINATION WITH SURROUNDING OFFICES...DECIDED TO INCREASE POPS TO CHANCE CATEGORY MON/MON NT CSRA...TRENDING LOWER TO THE EAST. ALSO...INDICATIONS ARE THAT LOW LEVEL FLOW TO VEER AROUND TO E/SE...AND THIS MIGHT LEAD TO CLOUDINESS ISSUES. COMBINATION OF COOLER AIR MASS BEHIND THE FRONT PLUS POSSIBLE CLOUDINESS LEADS TO COOLER MAX TEMPS MON/TUE AND MOS TEMPS LOOK OK. MODELS SLOWLY PUSH FRONT TO THE S/SW BY TUE...BUT MAY STILL BE CLOSE ENOUGH TO OUR W/SW FA TO WARRANT SOME POPS. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... MODELS IN AGREEMENT IN CONTINUING A RIDGE WEST/TROUGH EAST UPPER PATTERN THROUGH THE PERIOD. LATEST MODELS INDICATING FRONT SHOULD CONTINUE TO PUSH SLOWLY SOUTH FOR WED/THU AND WILL REMAIN FAR ENOUGH TO OUR SOUTH NOT TO AFFECT OUR FA. EXPECT MODERATING TEMPS.

LOW LEVEL COOL AIR ADVECTION NORTH OF THE FRONT COVERING MUCH OF THE AREA IS LIMITING CONVECTIVE ACTIVITY. BEST CHANCES SOUTH PART AND IN THE CSRA. AIRMASS MARGINALLY UNSTABLE WITH LIS -4/-5..TT 45 AND PWS STILL NEAR 2 INCHES. CONVECTIVE TEMPERATURES ARE FAIRLY HIGH IN THE LOWER 90S.
