Area forecast discussion, Sep 3, 2:09 PM EDT, 1 hour 17 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE COLUMBIA SC 209 PM EDT WED SEP 3 2014 .SYNOPSIS... HIGH PRESSURE CENTERED OFF THE SOUTHEAST COAST WILL CIRCULATE MOIST AIR INTO THE FORECAST AREA THROUGH THURSDAY. A PERSISTENT UPPER RIDGE WILL HELP MAINTAIN THE HOT TEMPERATURES. && .NEAR TERM /THROUGH TONIGHT/... RIDGE ALOFT AND A MOIST SOUTHEASTERLY LOW LEVEL FLOW WILL CONTINUE OVER THE ARE THROUGH TONIGHT. WEATHER CONDITIONS WILL BE SIMILAR TO THOSE OVER THE PAST SEVERAL DAYS. EXPECT SCATTERED THUNDERSTORMS THIS AFTERNOON AND EVENING. BEST CHANCE IS TO THE NORTH AND WEST OF INTERSTATE 20 AS INDICATED BY HIGH RESOLUTION MODELS. RAIN CHANCE IS IN THE 30 TO 35 PERCENT RANGE. THUNDERSTORM COVERAGE SHOULD BEGIN DECREASING DURING THE EVENING. HIGH LOW-LEVEL MOISTURE AND COOLING WITH LIGHT WIND SHOULD RESULT IN AREAS OF FOG DURING THE EARLY MORNING HOURS. RECENT VERIFICATION FAVORS THE WARMER TEMPERATURE GUIDANCE. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... HIGH PRESSURE AT THE SURFACE WILL REMAIN OFF THE SOUTHEAST COAST THROUGH THE PERIOD. THIS WILL KEEP A MOIST ONSHORE FLOW MOVING INTO THE REGION. STRONG HEATING DURING THE AFTERNOON WILL COMBINE WITH DEEP MOISTURE AND SOME CONVERGENCE ASSOCIATED WITH A LEE-SIDE TROUGH AND SEA-BREEZE FRONT TO HELP SUPPORT THUNDERSTORMS THURSDAY. THE LIMITING FACTOR BOTH DAYS WILL BE THE STRENGTH OF THE UPPER RIDGE ACROSS THE REGION...WHICH SHOULD HELP LIMIT THUNDERSTORM COVERAGE. WENT WITH GENERAL MODEL CONSENSUS OF POPS BETWEEN 20 AND 30 PERCENT. TEMPERATURES REMAIN WARM...AND WENT SLIGHTLY WARMER THAN CONSENSUS. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... THE LONGER RANGE MODELS CONTINUE TO DISPLAY A COLD FRONT MOVING TOWARDS AND INTO THE REGION SATURDAY AFTERNOON/EVENING...WITH THE FRONT THEN STALLING JUST TO THE SOUTH OF THE FORECAST AREA EARLY NEXT WEEK. DUE TO THE FRONTAL PASSAGE...AND ITS PROXIMITY TO THE AREA NEXT WEEK...THERE WILL CONTINUE TO BE A CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY THROUGH THE PERIOD. DUE TO THE FRONTAL PASSAGE...TEMPERATURES SHOULD DROP BACK DOWN TO NEAR NORMAL NUMBERS. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... MAINLY VFR CONDITIONS THROUGH THE PERIOD. SCATTERED THUNDERSTORMS WILL DEVELOP DURING THE AFTERNOON WITH THE BEST CHANCE TO THE NORTH AND WEST OF AREA TERMINAL. STORMS MAY LINGER INTO THE EVENING. STORM PROBABILITIES ARE IN THE 30-35 PERCENT RANGE SO NOT HIGH ENOUGH PROBABILITY TO INCLUDE MENTION IN TAFS AT THIS TIME. AS WAS THE CASE LAST NIGHT...WITH HIGH LOW LEVEL MOISTURE AND NOCTURNAL COOLING WILL LIKELY SEE AREAS OF FOG DEVELOP AFTER 09Z. AT THIS TIME WILL MENTION IFR CIGS AND VSBYS IN OGB AND AGS TAFS BETWEEN 1000 AND 13OO GMT. EXTENDED AVIATION OUTLOOK...RESTRICTIONS POSSIBLE IN LATE NIGHT AND EARLY MORNING STRATUS AND FOG. SCATTERED MAINLY AFTERNOON SHOWERS AND THUNDERSTORMS THROUGH SUNDAY. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...NONE. GA...NONE. &&
