AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE COLUMBIA SC 1018 PM EDT SUN AUG 18 2013 .SYNOPSIS... HIGH PRESSURE CENTERED OFF THE COAST WILL CIRCULATE MOIST AIR INTO THE FORECAST AREA THROUGH TUESDAY. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... TONIGHT...CONVERGENCE ASSOCIATED WITH THE WEDGE FRONT LIFTING NORTHWARD PLUS A MID-LEVEL SHORTWAVE SUPPORTED NUMEROUS SHOWERS AND THUNDERSTORMS EARLIER. ACTIVITY IS SLOWLY DECREASING IN COVERAGE AND INTENSITY. SOME HEAVY RAIN ALSO EARLIER THAT PROMPTED A COUPLE OF URBAN AND SMALL STREAM ADVYS, 60 PERCENT POPS AFTER 10 PM STILL GOOD AND WILL LOWER TO 30-40 PERCENT 02-03 AM AND EVENTUALLY DOWN TO 20 PERCENT CLOSER TO DAYBREAK. ALSO..EXPECT DIMINISHED COVERAGE LATER TONIGHT BECAUSE OF PREVIOUS CONVECTION AND DIURNAL COOLING. LOWS IN THE UPPER 60S TO LOWER 70S STILL OK. && .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/... THE MODELS SHOW HIGH MOISTURE CONTINUING THROUGH TUESDAY WITH PRECIPITABLE WATER AROUND 2 INCHES. THE NAM AND GFS INDICATE A WEAK SURFACE TROUGH MAY REMAIN CAUGHT IN THE SURFACE RIDGE. ALOFT...THE FORECAST AREA WILL REMAIN BETWEEN THE RIDGE OFF THE SOUTHEAST COAST AND WEAK TROUGH OVER THE MISSISSIPPI RIVER VALLEY. MOISTURE WILL REMAIN HIGH BETWEEN THESE TWO FEATURES WITH A TROPICAL CONNECTION. THERE MAY ALSO BE A SERIES OF SHORTWAVE TROUGHS. THE PATTERN SUPPORTS CONSIDERABLE CLOUDINESS WITH SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ESPECIALLY NEAR THE TIMES OF MAXIMUM HEATING. USED THE GUIDANCE CONSENSUS FOR THE POP FORECAST. THE HIGH PRECIPITABLE WATER SUPPORTS HEAVY DOWNPOURS WITH ANY SHOWERS OR THUNDERSTORMS. HIGH TEMPERATURES SHOULD BE A FEW DEGREES BELOW CLIMATOLOGY BECAUSE OF CLOUDINESS. LEANED TOWARD THE MAV MOS HIGH TEMPERATURES BECAUSE OF CONSISTENCY. USED THE GUIDANCE CONSENSUS FOR THE LOW TEMPERATURE. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... THE GFS AND ECMWF GENERALLY SHOW SURFACE RIDGING DURING THE MEDIUM-RANGE PERIOD. HIGH MOISTURE ASSOCIATED WITH LINGERING UPPER TROUGHING CAUGHT IN THE RIDGE SHOULD CONTINUE DURING MUCH OF THE PERIOD. THE PATTERN SUPPORTS A CHANCE OF MAINLY DIURNAL SHOWERS AND THUNDERSTORMS WITH TEMPERATURES NEAR CLIMATOLOGY.

WEDGE COULD BUILD BACK TO THE SOUTH OVERNIGHT. FOG COULD ALSO DEVELOP GIVEN LIGHT WINDS AND HIGH LOW LEVEL MOISTURE. MOS AND HIGH RES MODELS SUGGEST IFR CONDITIONS POSSIBLE.
