AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
348 PM EDT SAT SEP 2 2006

.SHORT TERM /THROUGH TONIGHT/...

STEADY RAIN WILL LINGER ACROSS THE NRN MTNS OF PENN THROUGH EARLY
THIS EVENING WITH AT LEAST SOME MINOR FLOODING OF POOR DRAINAGE
AREAS AND A FEW SMALL STREAMS CONTINUING. HOWEVER...FLASH FLOOD
GUIDANCE...AND EXPECTED ADDITIONAL RAINFALL OF LOCALLY UP TO 0.75
OF AN INCH NEGATES THE THREAT FOR ANY STAGES ON THE LARGER CREEKS
REACHING NEAR BANK FULL. STILL...WILL ALLOW THE FLASH FLOOD WATCH TO
CONTINUE THROUGH 8 PM /WHICH IS ROUGHLY THE FCST ENDING TIME OF
THE STEADY RAIN ACROSS THE NRN MTNS/...SINCE THE REGIONAL RADAR
LOOP SHOWS SOME BANDING OF HEAVIER RAIN PIVOTING BACK TO THE
NW..AND MOVING INTO THE ECENT/NCENT MTNS.

EXPECT AREAS OF DRIZZLE AND FOG TO PERSIST OVERNIGHT AS THE
REMNANTS OF ERNESTO PULL NORTH OF THE STATE AND TEMPS LINGER NEAR
THE DEWPOINT UNDER DIMINISHING SFC WINDS.

&&

.LONG TERM /SUNDAY THROUGH SATURDAY/...

QUIET WEATHER FOR THE REMAINDER OF THE LONG/HOLIDAY WEEKEND AS
TROPICAL SYSTEM EXITS TO THE NORTHEAST AND A NEW UPPER LOW DROPS
SOUTH OUT OF THE GREAT LAKES. THIS UPPER LOW WILL OPEN UP INTO A
WAVE MONDAY NIGHT AND ALLOW A SOUTHWEST FLOW TO RETURN TO THE
REGION. THIS COMBINED WITH A SHORT WAVE RIDING NORTH AHEAD OF THE
UPPER TROUGH WILL ALLOW FOR SCATTERED SHOWERS AND A FEW
THUNDERSTORMS ON TUESDAY. THE GFS PAINTS A LARGE AREA OF
PRECIPITATION BUT THIS IS LIKELY CONVECTIVE FEEDBACK. THE NAM IS
MORE CONVECTIVELY SPECKLED WITH ITS PRECIP FORECAST SO FEEL THAT A
GENERAL 30 PERCENT CHANCE IS A GOOD BET AT THIS TIME.

BY MID WEEK...LEFT A CHANCE OF PRECIPITATION THROUGH WEDNESDAY AS
THE UPPER TROUGH SLIDES THROUGH THE FORECAST AREA. ANOTHER SYSTEM
MOVES THROUGH FOR THE WEEKEND.

&&

.AVIATION...

WIDESPREAD IFR/LIFR CEILINGS AND VSBYS WILL CONTINUE THROUGH THE
MID MORNING SUNDAY BEFORE CONDITIONS GRADUALLY IMPROVE TO MAINLY
VFR BY 15Z SUNDAY. LINGERING MVFR CLOUDS MAY BE FOUND THROUGH 20Z
ACROSS THE NORTHERN AND WESTERN MTNS OF PENN...PARTICULARLY AT TAF
SITES KBFD AND KJST.
