AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
240 PM EDT MON MAY 7 2012

.SYNOPSIS...
LOW PRESSURE WILL MOVE ACROSS THE GREAT LAKES TUESDAY AND PUSH A
COLD FRONT SOUTH OF THE OHIO VALLEY LATER TUESDAY. THIS WILL BRING
SHOWERS AND A FEW THUNDERSTORMS LATER MONDAY THROUGH TUESDAY WITH
COOLER TEMPERATURES BY MID WEEK.

&&

.NEAR TERM /THROUGH TUESDAY/...
A WARM FRONT EXTENDS EAST WEST THIS EVENING ACROSS EASTERN OHIO
IN WESTERN PENNSYLVANIA NORTH OF PITTSBURGH. SHOWERS AND
SCATTERED THUNDERSTORMS WILL BE MOST LIKELY ACROSS THE I80 CORRIDOR'
NORTH OF THE WARM FRONT WITH MORE WIDELY SCATTERED SHOWERS IN THE
SOUTH. SOME STORMS COULD APPROACH SEVERE LIMITS DURING THE EVENING
HOURS. THESE SLOW MOVING STORM CAN ALSO PRODUCE HEAVY RAIN  WITH
AN INCH IN LESS THAN ONE HOUR POSSIBLE. IF THESE STORMS PERSIST
OVER THE SAME AREA FOR SEVERAL HOURS STREAM OR URBAN FLOODING
COULD RESULT. THE SHOWERS AND STORMS MAY BECOME MORE NUMEROUS
TOWARD DAYBREAK TUESDAY AS THE COLD FRONT WITH THE SYSTEM DRAWS
CLOSER. SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO TUESDAY
UNTIL THE FRONT MOVES EAST OF THE DISTRICT.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
THE SLOW MOVING COLD FRONT WILL PUSH EAST OF THE DISTRICT BY
TUESDAY EVENING...BUT A GOOD UPPER TROF BEHIND THE FRONT WILL
BRING A CONTINUED CHANCE OF SHOWERS FOR TUESDAY NIGHT INTO
WEDNESDAY. LOW LEVEL MOISTURE WILL BE DIMINISHING TUESDAY
NIGHT INTO WEDNESDAY WHICH WILL REDUCE THE THREAT OF HEAVY
RAIN.

THE COLD FRONT FINALLY DOES KICK SOUTHEAST OF THE AREA BY
WEDNESDAY AS THE NORTHERN STREAM DIPS WELL SOUTH OF WHERE IT HAS
TAKEN RESIDENCE IN RECENT WEEKS. AS THIS OCCURS...UPPER TROUGHING
BECOMES CENTERED OVER THE CWA FROM WEDNESDAY THROUGH THURSDAY.
WITH COLDER AIR ALOFT ENTERING THE PICTURE. SOME SHOWERS ARE
POSSIBLE ON WEDNESDAY AFTERNOON WITH HEATING AND THE COLD POOL
ALOFT. COOLER DRIER AIR WILL FEED INTO THE DISTRICT WITH HIGH
PRESSURE FOR THURSDAY.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
HIGH PRESSURE WILL THEN MOVE INTO THE OHIO VALLEY KEEPING THE
WEATHER DRY THROUGH SATURDAY.

A COLD FRONT IS PROGGED TO BRING SCATTERED SHOWERS SUNDAY.

TEMPERATURES ARE FORECAST TO BE A FEW DEGREES BELOW NORMAL THURSDAY
AND FRIDAY...WARMING TO SLIGHTLY ABOVE NORMAL FOR THE WEEKEND.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
A WARM FRONT WILL CONTINUE TO PUSH INTO NORTHERN PA THIS AFTERNOON.
AS SURFACE HEATING CONTINUES THIS AFTERNOON...WIDELY SCATTERED
COVERAGE OF THUNDERSTORMS WILL CONTINUE TO INCREASE ACROSS THE WARM
SECTOR. INCLUDED TEMPO GROUPS FOR THUNDERSTORMS FOR MOST TERMINAL
LOCATIONS THIS AFTERNOON...WITH IFR RESTRICTIONS POSSIBLE IN HEAVY
RAIN.

PREVAILING CONDITIONS WILL LOWER TO MVFR AND SHOWERS SHOULD BECOME
MORE NUMEROUS LATER TONIGHT INTO TUESDAY AS A COLD FRONT APPROACHES
FROM THE WEST. IFR RESTRICTIONS ARE ALSO POSSIBLE IN SCATTERED
EMBEDDED THUNDERSTORMS AND HEAVY RAIN.

.OUTLOOK...TUESDAY NIGHT THROUGH FRIDAY...
MVFR AND AREAS OF IFR RESTRICTIONS IN PRECIPITATION AND FOG WILL
LIKELY PERSIST THROUGH WEDNESDAY AS THE COLD FRONT SLOWLY MOVES EAST
THROUGH THE REGION AND AN UPPER TROUGH SLOWLY CROSSES THE OHIO
VALLEY.

CONDITIONS SHOULD IMPROVE TO VFR FOR THURSDAY AND FRIDAY AS SURFACE
HIGH PRESSURE WITH DRIER AIR MOVES IN FROM THE WEST.

&&

.PBZ WATCHES/WARNINGS/ADVISORIES...
MD...NONE.
OH...NONE.
PA...NONE.
WV...NONE.
