AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
317 PM EDT FRI MAY 27 2011

.SYNOPSIS...
A SLOWLY FILLING UPPER TROUGH WILL KEEP THE REGION UNSETTLED INTO
THE WEEKEND. A STRONG UPPER LEVEL RIDGE IS FORECAST TO BECOME
ESTABLISHED OVER THE EASTERN UNITED STATES BY THE SECOND HALF OF
THE WEEKEND. EVEN WARMER CONDITIONS ARE EXPECTED FOR THE EARLY TO
MIDDLE PART OF NEXT WEEK AS THE UPPER RIDGE STRENGTHENS
FURTHER...LIKELY BRINGING THE FIRST PROLONGED HEAT OF THE SEASON
TO THE REGION.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
SEVERE THUNDERSTORM WATCH FOR MUCH OF CENTRAL PA THROUGH 8 PM.

A QUASI-STATIONARY FRONT FROM MAINE DOWN OVER NRN PA INTO OHIO
CONTINUES TO BE A FOCUS FOR SHOWERS AND STORMS INTO THIS EVENING.
BEST INSTABILITY REMAINS ACROSS EASTERN AREAS ALONG AND SOUTH OF
THE FRONT. PROGS SHOW SOME INCREASE IN WIND WITH HEIGHT BUT VERY
LITTLE DIRECTIONAL SHEAR. SO WITH THE EXCEPTION OF VERY NEAR THE
FRONT...IT LOOKS LIKE IT WILL BE A HIGH CAPE LOW SHEAR DAY...WHICH
WILL TEND TOWARD THE MAIN THREATS OF LOCALIZED DAMAGING WINDSB AND
POSS LARGE HAIL. IT WILL ALSO CREATE THE RISK OF LOCALLY HEAVY
RAIN. AREAS THAT GOT HIT YESTERDAY WILL BE ESPECIALLY VULNERABLE
TO FLOODING...BUT CONFIDENCE IS TOO LOW ON A THREAT ZONE FOR ANY
KIND OF WATCH.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH 6 AM SATURDAY/...
CONVECTION THAT IS UNDERWAY THIS EVENING WILL GRADUALLY BECOME
MORE AND MORE SCATTERED OVERNIGHT AS WE LOSE THE
INSTABILITY...THOUGH SHOWERS MAY PERSIST THROUGH THE OVERNIGHT IN
THE NORTHEAST. THE BOUNDARY THAT IS HANGING IN OVER THE AREA IS
FINALLY FCST TO WASH OUT...LEAVING A STILL MOIST SOUTHERLY FLOW
IN ITS PLACE RIGHT INTO THE WEEKEND.

OVERNIGHT LOWS TONIGHT WILL BE QUITE MILD WITH HIGH HUMIDITY.
TEMPS SHUD AVERAGE AROUND 10 DEG ABOVE NORMAL.

&&

.LONG TERM /SATURDAY THROUGH FRIDAY/...
THE UPPER TROUGH WILL MOVE EAST AND GRADUALLY FILL ACROSS THE
CENTRAL APPALACHIANS FRI NIGHT AND SATURDAY. THE AXIS OF
RELATIVELY HIGH PWAT AIR UNDER THE SOUTHERLY FLOW AHEAD OF THE
TROUGH WILL GRADUALLY PINCH OFF AND MOVE EAST AS THE UPPER TROUGH
WEAKENS AND LIFTS OUT. SATURDAY WILL STILL HAVE A FEW SHOWERS
AROUND...BUT CHANCES SHUD BE LESS THAN TODAY AS THE FRONT
CONTINUES TO WASH UNDER THE DWINDLING UPPER FORCING.

BY SUNDAY A STRONG SURGE IN THE UPPER RIDGE WILL BEGIN...BRINGING
THE SEASON'S FIRST REAL SHOT OF HIGH HEAT. THE 500 RIDGE IS FCST
TO BLOW UP TO MORE THAN 5900M OVER THE NERN US...MORE THAN 2 STD
DEV ABOVE NORMAL. THE QUESTION WILL BE HOW LONG THIS RIDGE HOLDS
ON AS THE GEFS CARVES OFF THE NORTHERN EDGE BY MID WEEK COURTESY
OF A SHORTWAVE THAT IS MADE TO SLIDE THRU THE GR LAKES AND NERN
US...WHILE THE ECMWF HOLDS ONTO THE BIG HEIGHTS FOR AT LEAST A DAY
LONGER. IT ALL POINTS TO TEMPS WELL INTO THE 80S TO NEAR 90 FROM
SUNDAY INTO MID WEEK. THE WARM UPPER TEMPS SHUD HELP KEEP A LID
ON CONVECTION SO I AVOIDED THE STANDARD TEMPTATION OF MENTIONING
AFTERNOON SHOWERS AND STORMS GIVEN THE EXPECTED HEAT AND HUMIDITY.

A FRONT SHUD EVENTUALLY DROP OUT OF CANADA AND BRING A RESPITE
FROM THE HEAT SOME TIME DURING THE MID TO LATE WEEK.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
AS OF THE 18Z ISSUANCE...THE EASTERN HALF OF THE STATE IS UNDER VFR
CONDITIONS...WITH SHOWERS AND LINGERING IFR CEILINGS OVER THE THE
WEST. THE MAIN THREAT FOR THE REMAINDER OF THE DAY WILL BE THE
RETURN OF SHRA/TSRA TO THE REGION THIS AFTERNOON. ENVIRONMENTAL
CONDITIONS ARE ONCE AGAIN FAVORABLE FOR THE DEVELOPMENT OF
SCATTERED SHRA/TSRA...ESPECIALLY IN THE SOUTHEASTERN PART OF THE
STATE. THE SHRA/TSRA WILL FOLLOW A TYPICAL DIURNAL PATTERN...AND
MOST STORMS SHOULD DISSIPATE BY 03Z. AFTERWARD...PATCHY MVFR FOG
AND IFR/LIFR CEILINGS WILL SET IN THROUGH THE MORNING HOURS.

OUTLOOK...
SAT...MAINLY VFR WITH ISOLATED SHRA/TSRA.
SUN-WED...MAINLY VFR...BUT ISOLATED SHRA AND TSRA WILL BE POSSIBLE
AT TIMES.

&&

.EQUIPMENT...
CONTRACTORS STILL WORKING ON HARRISBURG NOAA WEATHER RADIO WILL
HOPEFULLY HAVE IT BACK TO NORMAL BY THE END OF THE DAY.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
NONE.
