.SYNOPSIS...
A WEAK COLD FRONT WILL SLIDE EAST ACROSS THE REGION
TONIGHT...BEFORE RETREATING BACK TO THE NORTH AS A WARM FRONT
EARLY TUESDAY. ANOTHER COLD FRONT WILL PUSH SOUTHEAST ACROSS
PENNSYLVANIA TUESDAY NIGHT AND EARLY WEDNESDAY. THESE WEATHER
FEATURES WILL SPARK A FEW ROUNDS OF SHOWERS AND THUNDERSTORMS THIS
EVENING THROUGH TUESDAY EVENING. A POOL OF MUCH COOLER AIR ALOFT
WILL BRING SOME AFTERNOON SHOWERS TO MAINLY THE NORTHERN MOUNTAINS
WEDNESDAY. HIGH PRESSURE BUILDING OVER THE COMMONWEALTH THURSDAY
AND FRIDAY WILL BRING CLEARING AND DRY CONDITIONS.

&&

.NEAR TERM /UNTIL MIDNIGHT TONIGHT/...
BROAD...AND RELATIVELY STRONG SOUTHWESTERLY FLOW AT LLVLS
AHEAD OF A COLD FRONT WILL COMBINE WITH THE VERY WARM AND MOIST
AIRMASS TO TRIGGER FAIRLY NUMEROUS SHOWERS AND THUNDERSTORMS
ACROSS THE NW HALF OF PENN THROUGH EARLY TONIGHT. A FEW OF THE
STORMS WILL BE STRONG TO LOCALLY SEVERE...WITH THE MAIN SVR
WEATHER THREAT BEING DAMAGING MICROBURST WINDS INVOF BOWING LINE

UPPER SHORTWAVE TROF CROSSING THE LOWER GLAKES THIS EVENING IS
ACCOMPANIED BY THE NOSE OF A 90 KT 300 MB JET MAX /CROSSING
SOUTHERN LOWER MICHIGAN AT 2230Z/. LARGE SCALE LIFT WILL CONTINUE
TO MOVE EAST ACROSS OUR FCST AREA OVERNIGHT...BUT WANING SFC BASED
HEATING AND DECREASING LAPSE RATES IN THE 850-500 MB LAYER WILL
LEAD TO MORE ISOLATED CONVECTION BY MIDNIGHT TONIGHT.

&&

.SHORT TERM /MIDNIGHT THROUGH 6 PM TUESDAY/...
CONVECTION SHOULD DIMINISH A GREAT DEAL LATE TONIGHT AND EARLY
WEDNESDAY AS A WEAK COLD FRONT SLIDES EAST ACROSS THE FCST AREA
THEN WASHES OUT ACROSS CENTRAL OR SOUTHERN PENN BEFORE DAYBREAK
WED.

PATCHY VALLEY FOG IS POSSIBLE ACROSS NRN PENN WHERE THE BULK OF
THE EVENING RAIN OCCURRED.

LOW TEMPS WILL RANGE FORM THE MID 60S ACROSS THE MTNS...TO AROUND
70F ACROSS THE LOWER SUSQ VALLEY.

TUESDAY AFTERNOON AND EVENING...WITH DEEP LAYER PW APPROACHING 2"
AND 850 MB LLJ >40 KTS PUSHING INTO THE LAUREL HIGHLANDS LATE
AFTERNOON AND EVENING. WARM AND MUGGY CONDITIONS WILL PREVAIL FOR
ANOTHER DAY...WITH HIGHS RANGING FROM UPPER 70S NORTH TO UPPER 80S
SOUTHEAST.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
NOT MANY BIG CHANGES TO PREVIOUS EXTENDED FORECAST. TSTM CHANCES
CONTINUE INTO TUE NIGHT/EARLY WED AS COLD FRONTAL BOUNDARY SLOWLY
CROSSES PA...FOLLOWED LATER IN THE DAY BY SECONDARY FRONT THAT
WILL PUSH HIGH PWAT AIR FURTHER TO THE SE. DID HOLD MENTION OF
LOW POPS IN SE INTO THU...THOUGH ACTIVITY MAY BE FURTHER SE.

HIGH PRESSURE TAKES OVER FOR LATE WEEK...WITH MOISTURE CREEPING
BACK IN FROM THE SOUTH OVER THE WEEKEND BRINGING INCREASING POPS
SAT INTO SUNDAY AS MID LEVEL LAPSE RATES GRADUALLY INCREASE.
BROAD TROUGH REMAINS OVERHEAD INTO EARLY NEXT WEEK...WITH MODELS
DIFFERING ON STRENGTH...SO LOW DAILY POPS WILL CONTINUE.

SE/...BUT GRADUALLY COOL BACK TO SEASONAL NORMS BY LATE
WEEK...FOLLOWED BY ANOTHER WARMUP NEXT WEEK.

SHRA/TSRA SHOULD DIE OUT ACROSS NORTHERN PA AFTER SUNSET...AS
ATMOS COOLS/STABILIZES. FORECAST CONCERN LATE TONIGHT WILL SHIFT
TOWARD THE POSSIBILITY LOW CIGS DEVELOPING OVR THE NW MTNS. LATEST
MDL DATA SUGGESTS A PLUME OF MOISTURE AHEAD OF DYING COLD FRONT
