AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
108 PM EDT THU JUN 9 2011

.SYNOPSIS...
THUNDERSTORM CHANCES WILL RETURN THIS AFTERNOON AND REMAIN IN THE
FORECAST THROUGH SATURDAY NIGHT AS A FRONT SAGS OVER THE UPPER
OHIO VALLEY.

&&

.NEAR TERM /THROUGH TONIGHT/...
SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED IN ADVANCE OF
APPROACHING FRONT. PRIMARY FACTOR FOR SEVERE WEATHER WILL BE
MODEST AMOUNTS OF INSTABILITY...ALTHOUGH WEAK LEVELS OF DEEP LAYER
SHEAR MAY PREVENT STORMS FROM FORMING INTO A SOLID LINE ACROSS THE
CWA. WITH FRONT MOVING SLOWLY...EXPECT THAT THE FRONT WILL REACH
NORTHWESTERN COUNTIES BY 18Z...THE PITTSBURGH METRO AREA BY
00Z...AND THEN DROPPING TO THE MASON-DIXON LINE AROUND 06Z. SEVERE
THREAT SHOULD DIMINISH DURING THE EVENING HOURS WITH THE LOSS OF
DAYTIME HEATING...ALTHOUGH SHOWERS AND SOME ISOLATED THUNDERSTORMS
WILL REMAIN OVERNIGHT.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
FRONT WILL REMAIN AROUND THE MASON-DIXON LINE ON FRIDAY...POSSIBLY
DRIFTING FARTHER TO THE NORTH. THIS WILL KEEP A CONTINUED CHANCE
FOR SHOWERS AND THUNDERSTORMS IN THE FORECAST. ONCE
AGAIN...CONVECTION WILL DIMINISH FRIDAY EVENING...ALTHOUGH ALL
LOCATIONS WILL STILL HAVE A CHANCE OF RAINFALL OVERNIGHT.

LOW PRESSURE WILL BE OVER MICHIGAN SATURDAY MORNING...AND AS THIS
SYSTEM MOVES TO THE NORTHEAST...A COLD FRONT WILL SWEEP THROUGH
THE REGION SATURDAY INTO SATURDAY NIGHT. THIS SHOULD FINALLY CLEAR
THE CHANCE FOR RAIN OUT OF THE FORECAST...BUT ANOTHER ROUND OF
SEVERE WEATHER COULD OCCUR ON SATURDAY AS THE COLD FRONT PASSES.
SKIES WILL BEGIN TO CLEAR ON SUNDAY...WITH COOLER AIR BRINGING
TEMPERATURES BACK TO NORMAL THAT DAY.

&&

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
JUDGING FROM RECENT NAEFS AND ECMWF MODEL OUTPUT, CONCUR WITH HPC
THAT HIGH PRESSURE, CENTERED OVER EASTERN CANADA, WILL PROVIDE DRY
CONDITIONS AND COMFORTABLE TEMPERATURES TUESDAY AND
WEDNESDAY. A LOW PRESSURE SYSTEM, COMING NORTHEASTWARD FROM THE
SOUTHERN PLAINS, MAY PRODUCE THUNDERSTORMS STARTING LATE WEDNESDAY
NIGHT.

SPECIFIC TEMPERATURES WERE BASED ON BLEND OF HPC GUIDANCE AND NAEFS
MEDIAN VALUES.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
RECENT RADAR DATA AND HRRR MODEL OUTPUT SHOWS A NEW PREFRONTAL BAND
OF MVFR THUNDERSTORMS, WITH SEVERE POTENTIAL, DEVELOPING NEAR THE
I-80 CORRIDOR BY 18Z, THEN MOVING SOUTHEASTWARD THROUGH THE
KZZV-KPIT-KLBE CORRIDOR BY ABOUT 20Z, AND KMGW BY 22Z.

COLD FRONT ITSELF WILL MOVE SOUTHEASTWARD THROUGH THE UPPER OHIO
VALLEY TOWARD 00Z. RECENT SREF MODEL OUTPUT SHOWS THE FRONT STALLING
TO PROVIDE ADDITIONAL BOUTS OF THUNDERSTORMS WITH RESTRICTIONS INTO
EARLY SUNDAY. PATCHES OF EARLY MORNING FOG AND HAZE CAN ALSO PROVIDE
RESTRICTIONS.

CANADIAN HIGH PRESSURE CAN PROVIDE MORE PREVALENT VFR LATER SUNDAY
INTO TUESDAY.

SURFACE WINDS WILL BE FROM THE WEST AND SOUTHWEST NEAR 10 KTS TODAY,
WITH HIGHER GUSTS IN THUNDERSTORMS. SURFACE WINDS WILL BE MORE FROM
THE NORTHWEST 4 TO 7 KTS TONIGHT.

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