AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
825 PM EDT WED JUL 23 2008
.SYNOPSIS...
A SLOW MOVING COLD FRONT WILL MOVE ACROSS THE STATE TONIGHT.
SEVERAL WAVES OF LOW PRESSURE RIDING NORTHWARD ALONG THE FRONT
WILL BRING HEAVY RAINFALL OF 2 INCHES OR MORE TO PARTS OF EASTERN
PENNSYLVANIA. IMPROVING CONDITIONS WILL OCCUR THURSDAY AS HIGH
PRESSURE BUILDS INTO THE REGION. FRIDAY WILL BE WARM AND DRY.
ANOTHER COLD FRONT WILL APPROACH THE REGION THIS WEEKEND WITH
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS ON SATURDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
00Z SFC ANALYSIS PLACES SFC TROUGH OVR EXTREME SOUTHEAST PA AND
COLD FRONT OVER WESTERN PA. ALTHOUGH RADAR STILL SHOWS PRETTY GOOD
COVERAGE OF SHWRS/TSTMS OVR NW MTNS NEAR UPPER LO...WILL CONTINUE
TO PLACE HIGHEST POPS ACROSS THE SOUTHEAST ZONES...WHERE STRONG LARGE
SCALE FORCING...FAVORABLE RIGHT ENTRANCE OF JET AND ANOMALOUS
PWATS ALL POINT TOWARD THE POTENTIAL OF LOCALLY HVY CONVECTIVE
RAINFALL OVERNIGHT. LATEST RADAR LOOP ALSO SUPPORTS THE IDEA OF
HVY RAIN POTENTIAL LATE THIS EVENING AND OVERNIGHT. FLASH FLOOD
GUIDANCE REMAINS HIGH ACROSS THE LOWER SUSQ VALLEY...SO NO FLOOD
WATCHES PLANNED AT THIS TIME...BUT SMALLER SCALE NUISANCE FLOODING
SEEMS LIKELY FROM SOME OF THE LOCALLY HEAVY BANDS THAT MANAGE TO
TRAIN ALONG FOR ANY AMOUNT OF TIME.
HAVE LOWERED OVERNIGHT POPS ACROSS THE CENTRAL MTNS BASED ON
LATEST RADAR TRENDS AND 18Z GUIDANCE. HOWEVER...CAN/T RULE OUT
ANOTHER SHWR/TSTM WITH PASSAGE OF SFC COLD FRONT LATER TONIGHT. HAVE
ALSO ADDED FOG TO THE FCST...WHICH SEEMS ALL BUT CERTAIN GIVEN THE
RECENT RAIN...LIGHT WIND AND PARTIAL CLEARING EXPECTED.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
COLD FRONT SHOULD BE EXITING OUR AREA COME THURSDAY MORNING. BOTH
NAM AND GFS SAY THAT PRECIP SHOULD BE EAST OF OUR AREA AFTER 12Z
THURSDAY. HOWEVER THE SREF KEEPS A DECENT PROBABILITY OF PRECIP
TOM MORNING AND THEREFORE WILL LEAVE IN A CHANCE ACROSS THE FAR
EASTERN ZONES. THE UPPER LEVEL TROUGH WILL STILL BE TO OUR WEST
THURSDAY... MEANING A CHANCE OF SHOWERS AND AN ISOLATED
THUNDERSTORM WILL CONTINUE. THE 700MB TROUGH WILL SLIDE JUST TO
OUR EAST WHICH SHOULD ACT TO CAP US FROM WIDESPREAD
SHOWERS...HOWEVER OUR NORTHERN AND CENTRAL COUNTIES SHOULD SEE A
FEW SHOWERS. EVEN WITHOUT ANY SHOWERS IT SHOULD BECOME MOSTLY
CLOUDY WITH MOSTLY FAIR WEATHER CUMULUS IN THE AFTERNOON. 850MB
TEMPS OF ONLY NEAR 12C AND THE MOSTLY CLOUDY SKIES SHOULD KEEP
HIGHS OF NEAR 70 IN THE HIGH TERRAIN OF THE NORTH TO NEAR 80 IN
THE LOWER SUSQUEHANNA VALLEY.
THURSDAY NIGHT SHOULD SEE CLEARING SKIES AND COOL TEMPERATURES.
LOWS SHOULD FALL AROUND 5 DEGREES BELOW NORMAL ACROSS MOST AREAS.
FRIDAY SHOULD BE A DRY DAY WITH JUST SOME FAIR WEATHER CUMULUS CLOUDS.
EXPECT MORE SUNSHINE THAN ON THURSDAY AND SLIGHTLY WARMER 850MB
TEMPS NEAR 13-14C. THIS SHOULD SUPPORT HIGHS ABOUT 5 DEGREES
WARMER THAN THURSDAY.
OUR NEXT DISTURBANCE WILL APPROACH THE AREA FRIDAY NIGHT IN THE
FORM A SHORTWAVE EJECTING OUT OF THE PLAINS. THIS WILL LIKELY BE
ASSOCIATED WITH AN AREA OF SHOWERS AND THUNDERSTORMS WELL OFF TO
OUR WEST... BUT THEY SHOULD DISSIPATE BEFORE REACHING OUR CWA.
THEREFORE WENT DRY FOR FRIDAY NIGHT WITH JUST AN INCREASE IN THE CLOUD
COVER EXPECTED.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
NOT A LOT OF CHANGE FROM YESTERDAY. DID EDGE POPS UP SOME FOR
SUNDAY AND SUNDAY NIGHT...AS THE UPPER LEVEL TROUGH MOVES ACROSS.
LEFT MONDAY AND TUE DRY...AND WENT WITH DRY CONDITIONS FOR
WED. EXPECT NW FLOW...AND NOT READY TO BUY INTO BLOW UP OF
FEATURE ON GFS.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
AREAS OF SHOWERS AND THUNDERSTORMS CONTINUE THIS EVENING ALONG A
COLD FRONT MOVING THROUGH WESTERN PENNSYLVANIA. MOST OF THE SIG
CONVECTIVE ACTIVITY IS EXPECTED OVER NWRN MTNS /KBFD/ AND EASTERN
PART OF DISTRICT...KMDT AND KIPT. BEHIND THE EARLIER AND CURRENT STORMS
A BROKEN LAYER AROUND FL100 WILL BE COMMON UNTIL WIDESPREAD BR
SETS UP AFTER SUNSET DUE TO ABUNDANT LOW LEVEL MOISTURE. PLACED
LOWER VISIBILITIES AND CEILINGS IN THE AIRFIELDS MOST PRONE TO
IT...KJST...KIPT AND KMDT.
THE FRONT SHOULD FINALLY BE OFFSHORE BY THURSDAY MORNING BRINGING
IN VFR CONDITIONS. HOWEVER WE WILL STILL BE UNDER THE UPPER LEVEL
TROUGH WHICH MAY CAUSE A FEW ISOLATED AFTERNOON SHOWERS TO
DEVELOP...WHICH MAY BRIEFLY LOWER CEILINGS AND VISIBILITIES TO
MVFR. VFR CONDITIONS EXPECTED FRIDAY AND SUNDAY... BUT YET ANOTHER
FRONT MAY BRING ANOTHER CHANCE OF THUNDERSTORMS ON SATURDAY.
