Severe Thunderstorm Warning 93, NWS Charleston, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
305 PM EDT THU JUN 12 2003

PUBLIC...ATLANTIC RIDGE HOLDS ACROSS THE SOUTHEAST THROUGH SATURDAY.
DEEP SOUTHWEST FLOW WILL CONTINUE BRINGING IN THE HIGH MOISTURE
CONTENT. NUMEROUS DIFFICULT-TO-TIME SHORTWAVES PASS THROUGH OR CLOSE
TO THE FORECAST AREA DURING THIS TIME. ADD TO THE MIX THE AFTERNOON
SEABREEZE AND CONVECTIVE BOUNDARIES AND THERE WILL BE A CHANCE OF
SHOWERS AND THUNDERSTORMS AT JUST ABOUT ANY TIME...BUT MAINLY DURING
THE AFTERNOON AND EVENING HOURS BECAUSE OF DAYTIME HEATING. WILL PUT
SLIGHTLY HIGHER POPS IN DURING THE DAY AND CUT BACK A BIT AT NIGHT.
MODELS STILL QUITE CERTAIN A BACKDOOR COLD FRONT WILL MOVE IN ON
SUNDAY AS LARGE HIGH BUILDS INTO THE MID ATLANTIC AND NEW ENGLAND.
APPEARS FRONT WILL BECOME STATIONARY RIGHT THROUGH OR VERY CLOSE TO
THE FORECAST AREA. LATEST RUN OF THE MRF HAS THE FRONT HANGING
AROUND THROUGH MUCH OF THE WEEK. THIS WILL ADD A FOCUSING MECHANISM
TO AN ALREADY VERY MOIST AND VERY UNSTABLE AIRMASS. FOR THE EXTENDED
PERIOD WIND FIELDS SHOW STEERING CURRENTS WILL BE LIGHT AND WITH
NUMEROUS SHOWERS AND THUNDERSTORMS A WIDESPREAD HEAVY RAIN EVENT
COULD BE POSSIBLE.

MARINE...SRLY FLOW TO CONTINUE FOR THE NEXT FEW DAYS WITH A
DECREASING TREND LATE FRI THROUGH THE WEEKEND. WILL CONTINUE TO
INCLUDE THE USUAL DIURNAL SHIFTS IN WIND DIRECTION. THE GFS
CONTINUES TO BRING THE COLD FRONT DOWN THE COAST AND INTO THE CWA
SUN NIGHT INTO TUE. SUSPECT WE WILL HAVE A TOUGH TIME GETTING A COLD
FRONT THIS FAR DOWN THE COAST PARTICULARLY THIS TIME OF YEAR DURING
THE DAY...THEREFORE DO NOT HAVE A LOT OF CONFIDENCE IN THIS SOLN.
PLAN TO DOWNPLAY THIS SCENARIO SIMILAR TO WHAT SURROUNDING OFFICES
HAVE DONE AS SUSPECT NOT SO MUCH COOL AIR WILL PENETRATE THE AREA.
WILL RETURN FLOW TO SRLY LATER ON TUE. SMALL CRAFT ADVISORY
CONDITIONS ARE NOT EXPECTED THROUGH THE PERIOD.
