DANGELO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
1008 AM EDT SAT APR 28 2012

.SYNOPSIS...
A WAVE OF LOW PRESSURE WILL RIDE EASTWARD TODAY ALONG A FRONTAL
ZONE DRAPED FROM THE MID MISSISSIPPI VALLEY TO THE SOUTHERN MID-
ATLANTIC COAST. THIS WILL CREATE LIGHT RAIN FOR MUCH OF CENTRAL PA
LATE THIS AFTERNOON INTO EARLY TONIGHT. A LARGE DOME OF HIGH
PRESSURE WILL PUSH SOUTHWARD FROM ONTARIO CANADA TONIGHT AND
SUNDAY...PROVIDING FAIR WEATHER AND MODERATING TEMPERATURES FOR
SUNDAY AND MONDAY. EVEN WARMER WEATHER IS EXPECTED FOR THE REST OF
THE NEW WORK WEEK AS AN UPPER RIDGE BECOMES ANCHORED OVER THE
SOUTHEAST STATES AND WESTERN ATLANTIC. AT THE SAME TIME...THE
PATTERN SHOULD BECOME MORE UNSETTLED WITH SEVERAL OPPORTUNITIES
FOR CONVECTIVE RAINFALL.

&&

.NEAR TERM /THROUGH TONIGHT/...
HIGH CLOUDS WILL LOWER/THICKEN-UP QUICKLY ACROSS THE WESTERN HALF OF
THE CWA THROUGH EARLY THIS AFTERNOON WITH MOSTLY SUNNY SKIES ACROSS
THE MID SUSQ VALLEY /AND POINTS NORTH AND EAST/ YIELDING TO
INCREASING AFTERNOON CLOUDS WITH A CHANCE OF SOME LIGHT RAIN DURING
THE MID TO LATE AFTERNOON FROM KIPT SOUTH.

THE LEADING EDGE OF AN INITIAL BATCH OF VERY LIGHT RAIN WAS RACING
EAST /AT ABOUT 45-50KTS/ FROM FAR WRN PENN LATE THIS MORNING AND
WILL BRING A 1-2 HOUR PERIOD OF VERY LIGHT RAIN /JUST A FEW TO SVRL
HUNDREDTHS OF AN INCH/ TO OUR WESTERN AND CENTRAL CWA BETWEEN
15-18Z...FOLLOWED BY A FEW HOUR LULL IN THE ACTION.

THE SECOND AREA OF RAIN /NOW SPREADING INTO FAR NWRN OHIO/ IS ALSO
MOVING RAPIDLY TO THE EAST CLOSE TO THE SPEED OF THE MEAN 700-500 MB
FLOW AND WILL MOVE INTO THE REGION NEAR AND TO THE WEST OF ROUTE 219
BETWEEN 19-20Z...THEN SPREAD ACROSS THE REMAINDER CENTRAL AND SRN
PENN LATE TDY AND THIS EVENING.

POPS RAMPING TO NEAR 100 PERCENT ACROSS THE REGION NEAR...AND TO THE
SOUTH OF INTERSTATE 80 FOR THE LATE AFTN AND EVENING HOURS CONTINUES
TO LOOK IN GOOD SHAPE.

TEMPS WILL MOST LIKELY HOLD IN THE 40S OVER THE WEST AND 50S IN THE
VALLEYS OF THE EAST AS THE CLOUDS THICKEN UP LATE THIS MORNING AND
CUT DOWN ON THE INSOLATION.

ALL MODEL SOLUTIONS NOW VERY SIMILAR IN TIME/PLACE/SPEED OF THE
MAJOR MASS FEATURES AND RESULTING RAINFALL. THE SFC LOW PASSES WELL
TO THE SOUTH OF THE STATE AND DRY AIR OVER THE NORTH WILL MOST
LIKELY KEEP THE FAR NRN TIER DRY. WILL HOLD ONTO 20-30 POPS THERE TO
ALLOW FOR THE SMALL UNCERTAINTY IN THE NRN LIMIT OF THE RAINFALL.

QPF COULD BE LOWER THAN THE MDLS ARE PLAYING WITH THE DRY AIR IN
PLACE...AND SHOULD STAY UNDER 0.25 INCHES IN MOST LOCATIONS. THE
PRECIP WILL BEGIN IN THE AFTERNOON IN THE WEST AND EARLY EVENING
IN THE SE. BUT IT EXITS THE AREA VERY QUICKLY THIS EVENING/EARLY
TONIGHT.

LATEST SOLUTIONS CONTINUE TO BE MILD ENOUGH FOR ALL RAIN...ESP
WITH THE PRECIP HOLDING OFF UNTIL AFTN/EVENING.

THE LATEST 09Z SREF AND 12Z NAM SHOWS JUST A VERY SLIM CHC FOR SOME
HIGH ELEVATION SNOWFLAKES AT THE NRN EDGE OF THE PRECIP SHIELD THIS
LATE TDY AND THIS EVENING ACROSS PORTIONS OF CLEARFIELD...ELK AND
NWRN CENTRE COUNTIES WHERE 850-875 MB WET BULB TEMPS WILL BE NEAR
ZERO.

THIS SNOW /AND CHC FOR IT/ WILL BE SO INCONSEQUENTIAL THAT IT/S NOT
WORTH TRYING TO SPECKLE INTO THE GRIDS AT ELEVATIONS AROUND OR ABOVE
2000 FT NEAR I-80.

WE ARE STILL LOOKING AT A 4 TO 8-HOUR PERIOD OF MAINLY LIGHT
RAINFALL FOR THE ENTIRE EVENT ACROSS MAINLY THE SRN TWO-THIRDS OF
THE AREA WITH GREATEST AREAL COVERAGE OF THE CWA AROUND 00Z.
DECREASING POPS FROM W-E AFTER THE LOW/SFC WAVE PUSHES TO THE EAST.
THE END TO THE RAIN SHOULD BE AROUND OR JUST AFTER MIDNIGHT. THE
SKIES CLEAR OUT VERY QUICKLY AND ALMOST COMPLETELY FROM N TO S
OVERNIGHT. THE CLEARING AND LIGHT NRLY WIND WILL LEAD TO ANOTHER
COLD NIGHT AND ANOTHER CHANCE FOR A FREEZE. HAVE CHOSEN THE SAME
ROUTE AS LAST NIGHT AND POSTED A FREEZE WATCH FOR TONIGHT
/2ND-PERIOD WHILE STILL RUNNING THE CURRENT/1ST-PERIOD WARNING.
WHILE A LITTLE CONFUSING...IT SHOULD LET FOLKS KNOW TO NOT LET DOWN
THEIR GUARD AND PLANT FOR ANOTHER COUPLE OF DAYS. HAVE ALSO CHOSEN
TO NOT INCLUDE THE FAR SRN COS IN THE FREEZE WATCH...AS PROGGED MINS
ARE IN THE M30S THERE. THEY WILL MOST LIKELY GET A FROST IF THE
WINDS DIE OFF.

&&

.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
SUNNY SKIES SUNDAY DUE TO STRONG /1029MB/ HIGH PRESSURE OVER THE
GREAT LAKES. THE DRY AIR WILL MAKE IT TOUGH TO MAKE ANY CLOUDS
REACH THE CWA DESPITE A NNW FETCH OFF THE LOWER LAKES. THE FRONTAL
BOUNDARY DOES NOT GO TOO FAR TO THE S...AND MAY BUBBLE UP TO THE
NORTH AS A WARM FRONT WHICH COULD ENTER WRN PA. HOWEVER...THE DRY
AIR CONTINUES TO SIT OVER THE LOCAL AREA AND NIL CHC FOR PRECIP
EXISTS UNTIL AT LEAST MONDAY. HIGHS ON SUNDAY WILL RUN ABOUT 10F
HIGHER THAN TODAY/SATURDAY...BUT STILL A LITTLE BELOW NORMALS
WHICH ARE NOW IN THE 60S - EVEN IN THE NRN MTS. THE ONLY FORECAST
TROUBLE WILL BE SUNDAY NIGHT AS NEARLY IDEAL RADIATIONAL COOLING
WILL AGAIN PROVIDE THE LIKELIHOOD OF A FREEZE OVER MUCH IF NOT ALL
OF THE AREA. WILL HOLD OFF ON ANY FURTHER FLAGS AT THIS
POINT...BUT MONDAY AM LOOKS A DEG OR TWO COLDER THAN SUN AM.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
GENERALLY PROGRESSIVE WEST TO SWRLY UPPER FLOW IS EXPECTED THROUGH
THE LONG TERM PERIOD. THIS WILL BRING SEVERAL FRONTS AND CHANCES
FOR...MAINLY LIGHT...PCPN TO CENTRAL PA.

GRADUAL WARMING TREND CONTINUES MONDAY. HIGHS THROUGH NEXT WEEK
INCREASE ABOUT 5F EACH DAY IN RETURN FLOW ON BACK OF HIGH. TEMPS
WILL TOP OUT IN THE 70S FOR THE SECOND HALF OF THE WEEK...WITH
80S EVEN POSSIBLE IN SPOTS. INDIVIDUAL SHORTWAVES...WHICH ARE
VERY HARD TO RESOLVE AT THESE RANGES...WILL MODULATE OPPORTUNITIES
OF PCPN. THE NEXT HIGH CHC OF PRECIP WILL BE DURING A TIME OF MCS-
FAVORABLE CONDITIONS MONDAY NIGHT. WILL GO WITH POPS INCREASING TO
50 PCT IN THE WEST FOR MONDAY NIGHT...AND 40S FOR TUESDAY. THEN
PERPETUAL 30 POPS WILL BE CARRIED ON THRU FRIDAY.

&&

.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
THICKENING MID AND HIGH CLOUDS WILL CONTINUE OVERSPREAD THE REGION
TODAY BUT VFR CONDS WILL PREVAIL...EVEN IN SOME PERIODS OF AFTERNOON
LIGHT RAIN.

 LOW PRES RIDING EWD FM THE MID MS VLY THRU THE MID-SOUTH WILL
SPREAD LOWER CIGS ACROSS CENTRAL AND SRN PA AIRFIELDS WITH LIGHT
RAIN LIKELY SOUTH OF DUJ-IPT LINE BY LATE THIS AFTN.

KIPT WILL BE ON THE NRN EDGE OF PRECIP THIS EVENING...BUT LATEST
BLEND OF THE 09Z SREF AND 12Z NAM QPF INDICATES THAT SOME VERY LIGHT
AMTS OF RAIN ARE POSSIBLE THERE LATE TODAY AND EARLY TNGT.

MVFR CIGS APPEAR LIKELY OVR AT AOO/JST FM LATE THIS EVENING INTO THE
FIRST PART OF TNT...BEFORE A DRYING NLY FLOW BRINGS IMPROVING CONDS
AND CLEARING SKIES BY DAYBREAK SUNDAY.

OUTLOOK...
SUN...VFR/NO SIG WX EXPECTED.
MON-WED...MAINLY VFR WITH SCT TSTM IMPACTS POSSIBLE.
