AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE COLUMBIA SC 159 PM EDT MON JUN 18 2007 .SYNOPSIS... AN UPPER LEVEL RIDGE WILL BEGIN TO SHIFT EAST ON TUESDAY AS AN UPPER LEVEL DISTURBANCE MOVES THROUGH THE OHIO VALLEY. THE UPPER DISTURBANCE WILL MOVE INTO THE MID ATLANTIC BY WEDNESDAY...ALLOWING A FRONT TO PUSH INTO THE CAROLINAS...BRINGING SHOWERS AND THUNDERSTORMS TO THE AREA. && .NEAR TERM /THROUGH TONIGHT/... UPPER LEVEL RIDGE REMAINS IN CONTROL OVER THE SOUTHEAST AND MOSTLY CLEAR SKIES SHOULD PREVAIL. SOME AFTERNOON CONVECTION HAS DEVELOPED IN THE MOUNTAINS AND SOME ISOLATED STORMS MAY DEVELOP ALONG THE CENTRAL SAVANNAH RIVER AREA BY LATE AFTERNOON...BUT THEY SHOULD BE FEW AND WILL NOT MENTION IN THE OVERNIGHT FORECAST. WILL ASSESS A BIT LATER AND DETERMINE IF A PRE-FIRST PERIOD GROUP IS NEEDED. AFTER TEMPERATURES TOP OUT IN THE MID TO UPPER 90S TODAY...TEMPERATURES SHOULD BE A FEW DEGREES WARMER TUESDAY MORNING...COMPARED TO THIS MORNING. && .SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... ATMOSPHERIC MOISTURE WILL BE ON THE INCREASE TUESDAY...AS THE UPPER RIDGE AXIS SHIFTS EASTWARD...GIVING WAY TO AN APPROACHING SHORTWAVE AND ASSOCIATED COLD FRONT. MODEL INSTABILITIES BECOME MODERATE BY TUESDAY AFTERNOON AND WITH LOWERING UPPER HEIGHTS AND TEMPERATURES IN THE LOW TO MID 90S...EXPECT TO SEE SCATTERED THUNDERSTORMS TO DEVELOP. THE BEST COVERAGE MAY BE IN THE CENTRAL SAVANNAH RIVER AREA WHERE THE MOISTURE WILL BE BEST. DO NOT THINK WE WILL SEE CONTINUED ACTIVITY DURING THE OVERNIGHT HOURS TUESDAY NIGHT...BUT WILL KEEP SLIGHT CHANCE POPS AS THE FRONTAL BOUNDARY MOVES INTO THE AREA. WEDNESDAY APPEARS TO BE THE BEST CHANCE FOR SHOWERS AND THUNDERSTORMS AS THE FRONTAL BOUNDARY WILL BE BISECTING THE FORECAST AREA WITH SOME WEAK UPPER SUPPORT PRESENT. THE BEST CHANCES SHOULD BE ALONG AND EAST OF A CAE/AGS LINE. SREF GUIDANCE SHOWS MODERATE INSTABILITY AND GIVES HIGH PROBABILITIES OF MEASURABLE PRECIPITATION ACROSS THE FORECAST AREA. HAVE BUMPED UP POPS TO LOW LIKELY EAST OF I-20 WHERE THERE WOULD BE SOME INTERACTION WITH THE SEA BREEZE BOUNDARY. WILL CARRY HIGH CHANCE POPS IN THE WEST. PRECIPITATION SHOULD CONTINUE INTO THE EVENING HOURS...ESPECIALLY IN THE EASTERN FORECAST AREA...BUT DIMINISH DURING THE OVERNIGHT HOURS. TEMPERATURES WILL BE TRICKY ON WEDNESDAY AS CLOUDS AND WHERE THE FRONTAL BOUNDARY IS LOCATED WILL HAVE AN IMPACT ON MAXIMUM TEMPERATURES. THURSDAY...DEEP LAYER MOISTURE WILL SHIFT SOUTHEAST OFF THE COAST AS MODELS DEVELOP A SURFACE LOW OFF THE COAST. WILL CONTINUE WITH LOW CHANCE POPS ALONG THE EASTERN COUNTIES WHERE LINGERING CONVERGENCE BOUNDARIES WILL BE POSSIBLE AND MODELS HINT AT ENHANCED INSTABILITY. && .LONG TERM /FRIDAY THROUGH MONDAY/... MODELS ARE IN RELATIVELY GOOD AGREEMENT IN THE MEDIUM RANGE...BUT DO DIVERGE A BIT BY DAY 7. THE EXTENDED FORECAST WILL FEATURE A MEAN RIDGE OVER THE INTERMOUNTAIN WEST SHIFTING INTO THE CENTRAL PLAINS BY EARLY NEXT WEEK. HPC GUIDANCE LEANED MORE TOWARD THE GFS...WHICH BRINGS A WEAK NORTHERN STREAM SYSTEM INTO THE CAROLINAS OVER THE WEEKEND. THE AREA APPEARS TO BE IN BETWEEN SYSTEMS ON FRIDAY AS THE WEAK SYSTEM OFF THE SOUTHEAST COAST PULLS AWAY AND THE NEXT SHORTWAVE MOVES INTO THE OHIO VALLEY. THERE WILL BE LITTLE INSTABILITY AVAILABLE ON FRIDAY AND PRECIPITABLE WATER VALUES WILL BE AROUND AN INCH...WHICH WILL ALSO INHIBIT DIURNAL CONVECTION ON FRIDAY. AS THE SHORTWAVE AND ASSOCIATED COLD FRONT APPROACH ON SATURDAY...MOISTURE INCREASES AND THE ATMOSPHERE BECOMES A BIT MORE UNSTABLE...AND WILL CARRY SLIGHT CHANCE POPS. CHANCE OF PRECIPITATION INCREASE ON SUNDAY AS WEAK SHORTWAVE ENERGY MOVES INTO THE CAROLINAS AND A FRONTAL BOUNDARY APPROACHES. THE BOUNDARY SLIDES THROUGH BY SUNDAY NIGHT AND UPPER RIDGING BUILDS BACK OVER THE SOUTHEAST ON MONDAY. THIS WILL LIMIT CONVECTION BUT THERE WILL LIKELY BE ENOUGH LOW LEVEL MOISTURE REMAINING TO TRIGGER ISOLATED AFTERNOON SHOWERS AND THUNDERSTORMS. TEMPERATURES THROUGHOUT THE PERIOD WILL REMAIN NEAR NORMAL. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... MOISTURE APPEARS LIMITED THIS AFTERNOON ESPECIALLY NORTH OF CAE...EXPECT SCATTERED CUMULUS. A FEW SHOWERS/THUNDERSTORMS MAY DEVELOP IN THE CSRA WHERE MOISTURE HIGHER AND INSTABILITY STRONGER. CUMULUS SHOULD DISSIPATE AFTER SUNSET. PATCHY FOG AT OGB/AGS LAST NIGHT...MODELS SUGGEST LOW LEVEL MOISTURE WILL INCREASE TONIGHT AND WILL FORECAST PERIOD OF FOG TOWARD MORNING...MVFR. VFR DEVELOPING AFTER SUNRISE. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...NONE. GA...NONE. && SYNOPSIS...HC NEAR TERM...HC SHORT TERM...HC LONG TERM...HC AVIATION...AWP
