Area forecast discussion, Jun 15, 3:40 PM EDT, 3 hours 27 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 340 PM EDT FRI JUN 15 2001 AFTER THE LAST SEVERAL DAYS...THE FORECAST TODAY SEEMS FAIRLY STRAIGHTFORWARD. THE MODELS SHOW A TRANSITION IN THE UPPER PATTERN OVER THE NEXT 48 HOURS AS THE OLD LOW LIFTS UP THE COAST AND FINALLY WEAKENS AND A LARGE UPPER TROF LIFTS FROM THE PLAINS...ACROSS THE GREAT LAKES...TO EASTERN CANADA. IN ITS PLACE...A LARGE UPPER RIDGE WILL BUILD OVER THE SOUTHERN PLAINS...AND WILL NOSE IN OVER THE SOUTHEAST BY SUNDAY. AS THE UPPER TROF LIFTS OUT OF THE PLAINS TONIGHT AND ACROSS THE GREAT LAKES ON SATURDAY...A COLD FRONT WILL APPROACH FROM THE WEST TONIGHT. SHOWERS AND THUNDERSTORMS AHEAD OF THE FRONT OVER WESTERN TENNESSEE MAY SURVIVE TO MOVE INTO THE MOUNTAINS LATER TONIGHT. WILL KEEP A CHANCE OF PRECIP IN THE WESTERN ZONES TO ACCOUNT FOR THIS. OVER THE REMAINDER OF THE ZONES...THE SHOWERS AND STORMS SHOULD DIMINISH BY MIDNIGHT. CURRENT THINKING IS THAT THE BOUNDARY WILL CROSS THE MOUNTAINS IN THE LATE MORNING SATURDAY...AND THE PIEDMONT ON SATURDAY AFTERNOON. THE BEST UPPER SUPPORT APPEARS TO MOVE PAST TO THE NORTH AS THE UPPER TROF LIFTS OUT...ALTHOUGH THE AIR MASS AHEAD OF THE BOUNDARY WILL STILL HAVE PLENTY OF LOW LEVEL MOISTURE AND INSTABILITY. LOW LEVEL FORCING ALONG THE BOUNDARY SHOULD BE SUFFICIENT TO TRIGGER SOME THUNDERSTORMS. WILL GO WITH A SLIGHTLY HIGHER CHANCE OVER THE EASTERN ZONES WHERE THE FRONT WILL PASS LATER IN THE AFTERNOON. THE FRONT...SUCH THAT IT IS...SHOULD BE EAST OF THE FORECAST AREA BY SATURDAY EVENING. ALTHOUGH THE FRONT WILL BE WEAKENING AS IT MOVES PAST...SOMEWHAT DRIER AND MORE STABLE AIR WILL MOVE IN ACROSS THE FORECAST AREA ON SUNDAY. THIS SHOULD PRECLUDE ALL BUT ISOLATED SHOWERS OVER THE MOUNTAINS. TEMPS WILL NOT DROP...BUT SHOULD ACTUALLY BE A FEW DEGREES WARMER SUNDAY AS THE UPPER RIDGE NOSES IN. AS FOR THE EXTENDED...THE MRF SHOWS MOISTURE INCREASING BY THE MIDDLE PART OF THE WEEK WITH A FEW DISTURBANCES MOVING THROUGH IN THE LATTER HALF OF THE WEEK. WILL INTRODUCE A CHANCE OF SHOWERS AND THUNDERSTORMS BEGINNING WEDNESDAY AND CONTINUING THROUGH THE END OF THE WEEK.
