DEW POINTS HAVE RETURNED TO THE UPPER 60S, AND SOME 70F ARE ON
SCHEDULE AT THE DOORSTEP OF THE FA. THE SURGE IN MOISTURE IS
AHEAD OF AN APPROACHING SYSTEM THAT IS MODELED TO COME TOGETHER
AS IT MAKES ITS PASS OVER THE COMMONWEALTH. 12Z SOUNDING DATA
SHOWS PW'S APPROACHING 1.75", ON TRACK TO MOVE TOWARD 2", WHICH
PUTS IT CLOSER TO THE 99TH PERCENTILE OF CLIMO. BOTH THE
NAEFS/ECMWF ESAT'S HAVE TRENDED WETTER WITH RETURN INTERVALS
5-10 YRS WITH A COINCIDENT INCREASE TO AROUND 3 STANDARD
DEVIATIONS ABOVE NORMAL. THIS INCREASES OUR CONFIDENCE IN WPC'S
UPWARD BUMP FROM MARGINAL TO SLIGHT RISK OF RAINFALL EXCEEDING
FFG, BUT WITH RESPECT TO THAT, OUR 6 HOUR FFG VALUES ARE IN THE
3-5" RANGE, SO ISOLATED FLOODING, SHOULD IT DEVELOP, WILL BE
MOST LIKELY IN PRONE AREAS THAT HAVE RUNOFF ISSUES. THUNDER
CHANCES GROW WITH TIME BUT OVERALL, SHEAR/INSTABILITY ARE
LACKING FOR ANYTHING BEYOND THE CONSISTENTLY ADVERTISED GENERAL
RISK. ONE FLY IN THE OINTMENT IN THAT WILL BE TMRW, WHEN THE
FRONT IS MAKING ITS PUSH FOR PASSAGE. SOME MODELING REFLECTS A
WEAK SURFACE WAVE DEVELOPING/RIDING ALONG THE BOUNDARY AT THAT
TIME, WHICH OFFER JUST ENOUGH TO ENHANCE THE THUNDER RISK
BRIEFLY IN OUR SOUTHEAST AS WE MOVE INTO EARLY TMRW
PM...SOMETHING TO WATCH.
ALL WINDS DOWN BY 00Z WED AS THE FRONT COMPLETES PASSAGE AND THE
PARENT TROF SOON FOLLOWS. IT'LL SWEEP IN A PLEASANTLY COOLER AND
DRIER AIR MASS, WHICH RESULTS IN 40S/50S FOR LOWS, AND 70S FOR
HIGHS TO FINISH OUT THE WEEK. A WEEKEND WARMUP ENSUES, AND WE
JUST MIGHT SEE TEMPERATURES FLIRT WITH 80F AGAIN BY EARLY NEXT
WEEK IN WHAT LOOKS TO BE A CONTINUED DRY PATTERN FOR NOW, BUT
WE'LL HAVE TO WATCH THE TROPICS TO SEE HOW EVOLUTIONS THERE
WRINKLE THE PATTERN.

SHOWERS ARE CONTINUING TO MOVE THROUGH THE AREA BUT THERE SHOULD
BE A BRIEF LULL IN ACTIVITY OVER THE NEXT FEW HOURS UNTIL AROUND
MIDNIGHT. SHOWERS WILL THEN RAMP BACK UP FROM THE SOUTH AND MOVE
NORTHEAST THROUGH THE AREA OVERNIGHT AND TOMORROW MORNING.
CONFIDENCE IN THUNDER IS TOO LOW TO MENTION CURRENTLY. CIGS
REMAIN LOW WITH SOME PLACES BOUNCING BETWEEN IFR AND MVFR. CIGS
WILL BEGIN TO LIFT TOMORROW AFTERNOON BEHIND THE COLD FRONT.
WINDS WILL BE CALM, TO LIGHT AND VARIABLE OVERNIGHT BUT WILL
SWITCH AROUND TO BE OUT OF THE NORTH TOMORROW AT 5-10 KTS
BEHIND THE COLD FRONT.
