AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
336 PM EDT TUE MAY 29 2012

.SYNOPSIS...
A COLD FRONT WILL PUSH ACROSS CENTRAL PENNSYLVANIA THIS EVENING
AND EARLY TONIGHT. A SECONDARY TROUGH WILL PASS THROUGH THE AREA
ON WEDNESDAY...FOLLOWED BY COOLER WEATHER FOR THURSDAY. UNSETTLED
WEATHER SHOULD RETURN LATE IN THE WEEK AS A LOW PRESSURE SYSTEM
DEVELOPS IN THE SOUTH-CENTRAL STATES AND MOVES NORTHEAST.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
ON-GOING SEVERE WEATHER IS ALREADY STARTING TO SLIDE OUT OF THE
NWRN COS. THE REAL COLD FRONT APPEARS RATHER NEBULOUS/ILL-DEFINED
AT THIS TIME...BUT DOES NOT APPEAR TO BE INTO NW PA JUST YET AS
PRESSURES ARE FLAT OR CONTINUE TO FALL. WINDS HAVE SHIFTED SOME TO
THE W/NW OVER OH...AND SHOULD BE A GOOD SIGN FOR THE END OF THE
EVENT. SVR THREAT CONTINUES INTO THE EVENING IN THE FAR SE...BUT
SHOULD BE OVER IN THE CENTRAL COS IN THE NEXT 3-4 HRS. THREATS ARE
BOTH HAIL AND WIND. SB CAPES RUNNING ABOVE 3000J/KG IN THE ERN COS
RIGHT NOW PER SPC MESO ANALYSIS GRAPHIC...BUT A LITTLE CAP THERE
IS HELPING THE CONVECTION WAIT UNTIL THE PRE-FRONTAL TROUGH COMES
BY TO TAP INTO IT. SVR WATCHES COVER THE ENTIRE AREA...BUT THE NW
MAY BE CANCELLED SOON. SO FAR THE RAIN HAS NOT BEEN HEAVY ENOUGH
TO WARRANT ANY FLOOD ADVYS/WARNS. THE CELLS APPEAR TO BE MOVING
STEADILY...BUT HAVE LITTLE ORGANIZATION. THIS IS EXPECTED TO
CONTINUE INTO THE EVENING.

OVERNIGHT CLEARING WILL ALLOW SOME FOG TO FORM IN AREAS THAT HAVE
HAD RAIN. THE WINDS WILL GO VERY LIGHT WITHOUT MUCH OF A DYNAMIC
PUSH. OTHERWISE...TEMPS WILL DIP INTO THE M50S TO M60S...WHICH IS
ABOUT NORMAL FOR AN EARLY SUMMER DAY.

INSTABILITY GOES UP WITH THE HEATING OF THE DAY BEHIND THE MAIN
FRONT ON WED. PLUS...A TROUGH OF LOW PRESSURE SHOULD SWING THROUGH
THE REGION IN THE MIDDLE OF THE DAY AS WELL. WILL CONTINUE TO
MENTION SLIGHT CHCS OF THUNDER FOR MOST OF THE AREA EXCEPT THE
SC/SE. SMALL HAIL GUSTY WINDS ARE POSSIBLE FROM THESE CELLS WED
LATE MORNING AND AFTN. MAXES WILL BE 5-10F COOLER THAN TUES...AND
MUCH CLOSER TO NORMAL. THE SE WILL STILL BE 5-10F ABOVE NORMAL ON
MAXES WITH NEARLY FULL SUN.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
ANOTHER PROGRESSIVE SHORTWAVE TROUGH WILL DIVE ESEWD FM THE
ARROWHEAD OF MN AND TRACK ALONG THE U.S/CANADIAN BORDER REACHING
NRN NEW ENGLAND ON THURS. A SECONDARY COLD FRONT WILL ACCOMPANY
THIS SYSTEM AND PUSH EWD THROUGH CENTRAL PA WED NGT. NLY FLOW
ASSOCIATED WITH SFC HIGH PRESSURE SLIDING EWD INTO PA FM THE UPPER
MS VLY WILL BRING A MUCH COOLER AND DRIER AIRMASS TO THE REGION ON
THURS. BERYL WILL LIFT NEWD FM THE NC COAST INTO THE NRN ATLC BY
THE END OF THE PD. A STG MID-UPPER LEVEL TROUGH DIVING SEWD THRU
THE CENTRAL STATES SHOULD FORM AN AREA OF LOW PRES OVR THE SRN
PLAINS/LWR MS VLY WHICH SHOULD TRACK NWD INTO THE OH VLY/GRT LKS
FRI-FRI NGT.

THUR NGT-FRI MORNING LOOKS RATHER CHILLY ESP IN THE NRN TIER WITH
HIGH PRES OVRHEAD AND PWS BLW NORMAL. OVRRNG TYPE RAINS SHOULD
EVENTUALLY REACH THE AREA FRI-FRI NGT AS THE PLAINS SYS EVOLVES
NEWD INTO THE LWR LKS. MODEL SPREAD IS HIGH REGARDING THIS SYSTEM
SO OPTED FOR EVEN MODEL COMPROMISE SPLIT BETWEEN THE SLOWER GFS
AND PROGRESSIVE EURO.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
GFS/EC ENSEMBLE MEANS SHOW A H5 TROUGH PERSISTING OVER THE NE
STATES/NEW ENG WITH THE LOCAL AREA UNDER NW FLOW ON THE SW EDGE
OF THE LOW CENTER. INTERESTING TO NOTE THAT THE NAO IS FCST TO
APPROACH MINUS 3 WHICH WOULD FAVOR COOLER THAN NORMAL TEMPS.
HOWEVER THE GEFS WANTS TO REBOUND HEIGHTS ABOVE NORMAL WHILE THE
ECENS KEEPS A LW TROUGH IN PLACE WITH CLOSED LOW OVR NRN NEW ENG.
CONFIDENCE IS LESS THAN AVERAGE AND THEREFORE HEDGED LONG TERM
GRIDS TWD THE GLOBAL ENSEMBLE MEANS TO ADDRESS THE UNCERTAINTY IN
THE LARGE SCALE PATTERN.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
NEAR TERM AVIAITON CONCERNS REVOLVE AROUND ONGOING AND DEVELOPING
CONVECTION AREAWIDE. TRIED TO TIME MAIN AREA OF STORMS THROUGH
EACH AIRFIELD...HOWEVER...CONVECTIVE DEVELOPMENT WILL KEEP THE
CHANCE OF A TSRA AT ANY TIME THROUGH LATE AFTERNOON.

MAIN AREA OF SHRA/TSRA WILL EXIT THE EASTERN AREA AROUND 23Z AND
THEN AREAS OF BR WILL DEVELOP OVERNIGHT AT MOST SITES.

OUTLOOK...
WED...AM FOG POSS. ISOLD AFTN SHRA/TSRA POSS.
THU...NO SIG WX EXPECTED.
FRI...PM THUNDERSTORM IMPACTS POSSIBLE.
