245 PM EDT SAT JUN 1 2002

UPPER TROUGH TO E AND CUTOFF LOW IN GULF PRODUCING NW FLOW AND UPPER
DIFFLUENCE OVER AREA. STORMS ASSOCIATED WITH MID LEVEL IMPULSE
TRACKING SE THROUGH VA MAY JUST CLIP OUR AREA...BUT ENOUGH SUPPORT
FOR SCATTERED CONVECTION THROUGH EVENING...ESPECIALLY NC. ANOTHER
IMPULSE SCHEDULED FOR 06Z...BUT WITH LOSS OF HEATING WILL JUST PLAY
UP MOUNTAINS WITH THIS ONE. YET ANOTHER IMPULSE CROSSES AREA
SUN...AND OTHER THAN SLIGHTLY WARMER TEMPS/DEW POINTS...FORECAST
LOOKS SIMILAR TO TODAY. NO VORT MAX SUNDAY NIGHT...AND WILL ALLOW
CONVECTION TO ASSUME A REGUALR DIURNAL PATTERN OF AFTERNOONS AND
EVENINGS INTO EXTENDED. BACK DOOR COLD FRONT APPEARS TO HALT JUST NE
OF AREA MON. WITH A FEW MORE CLOUDS AROUND...WILL FOLLOW GUIDANCE
AND COOL AREA A FEW DEGREES FROM SUN TO MON. MEANWHILE...MINIMUM
TEMPERATURES WILL COME UP WITH THE DEW POINTS...APPROACHING 70 LEE
OF MOUNTAINS.

LATEST MEDIUM RANGE GUIDANCE SUGGESTS SLOWING DOWN PROGRESSION OF
UPPER TROF AND FRONTAL BOUNDARY LATE IN THE WEEK...TO THE POINT
WHERE IT REMAINS TO OUR WEST THROUGH SATURDAY. THIS WILL KEEP THE
FORECAST AREA IN A RELATIVELY WARM AND HUMID AIR MASS THROUGH THE
PERIOD...WITH GUIDANCE POPS ABOVE CLIMO EACH DAY. ALTHO THE FORECAST
IS LOOKING LIKE A BROKEN RECORD...FEEL LIKE THE CHANCE OF
AFTERNOON/EVENING THUNDERSTORMS SHOULD CONTINUE EACH DAY. LITTLE
CHANGE NEEDED TO KEEP TEMPS IN LINE WITH LATEST GUIDANCE.
