AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
633 PM EDT WED APR 10 2013

.SYNOPSIS...
A FRONTAL BOUNDARY WILL CONTINUE TO DRIFT ACROSS THE REGION INTO
THURSDAY WITH PERIODS OF SHOWERS AND THUNDERSTORMS. A COLD FRONT
WILL THEN CROSS THE REGION THURSDAY NIGHT INTO EARLY FRIDAY WITH
WIDESPREAD SHOWERS AND THUNDERSTORMS...FOLLOWED BY MUCH COOLER
TEMPERATURES FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
HAVE MADE A QUICK UPDATE TO FORECAST THROUGH LATE THIS EVENING TO
TAKE INTO ACCOUNT THE SEVERE THUNDERSTORM WATCH THAT HAS BEEN
ISSUED FOR MOST OF THE COUNTY WARNING AREA. SEVERAL LINES OF
SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ALONG AND JUST SOUTH OF THE
STATIONARY BOUNDARY THIS AFTERNOON IN AN AREA OF DECENT
INSTABILITY AND SHEAR...1000J/KG AND 35-50KTS RESPECTIVELY. THIS
HAS ALLOWED FOR SOME CELLS TO MAINTAIN THEMSELVES TO SEVERE
LIMITS. AS SUCH...UPDATED POPS THROUGH THE EVENING TO LIKELY AND
ADDED SEVERE MENTION. THE MOST RECENT HI RES MODEL RUNS SUGGEST
THAT THEY LINES OF CONVECTION WILL GRADUALLY SINK SOUTH FOR A
PERIOD THIS EVENING BEFORE WEAKENING AND LIFTING NORTHWARD AS THE
STRONGER SURFACE LOW AND COLD FRONT APPROACHES FOR LATER THURSDAY.

COLD FRONT WILL CONTINUE ITS SLOW TREK TO THE EAST. THE FRONT WILL
ONLY HAVE REACHED INDIANA BY THURSDAY MORNING...AND WILL MOVE INTO
CENTRAL OHIO BY LATE AFTERNOON. MODELS HAVE SOME WIDE VARIATIONS ON
TEMPERATURES...WHICH HAS BEEN THE CASE MUCH OF THE WEEK WITH THE
WOBBLING FRONT. COULD EASILY SEE A 20 DEGREE SPREAD IN HIGH
TEMPERATURES AGAIN TOMORROW...WITH LOW 60S TO THE NORTH AND NEAR 80
ACROSS WEST VIRGINIA.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
COLD FRONT WILL CROSS THE FORECAST AREA THURSDAY NIGHT...AND HAVE
CONTINUED THE CATEGORICAL POPS DURING THAT TIME PERIOD. MOST PLACES
SHOULD SEE BETWEEN HALF AN INCH AND AN INCH OF RAIN.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
COLD ADVECTION CONTINUES IN EARNEST RIGHT THROUGH THE DAY FRIDAY
INTO FRIDAY NIGHT AS 850 MB CONSENSUS TEMPERATURES FALL OFF INTO
THE -6 TO -8C RANGE. INCREASINGLY UNSTABLE CONDITIONS DUE TO
COLDER MID-LEVEL TEMPERATURES SLIDING OVER THE AREA AS WELL AS
CONTINUED WEAK SHORT WAVE ACTIVITY IN THE LARGER SCALE TROUGHING
OVER THE AREA WILL MAINTAIN A LOW END CHANCE OF RAIN SHOWERS
MIXING WITH SNOW SHOWERS FRIDAY NIGHT INTO SATURDAY.

THE COLD ADVECTION OF THE FIRST HALF OF THE WEEKEND WILL BE SHORT
LIVED...AS MID-LEVEL HEIGHTS START TO COME UP BY SUNDAY WITH THE
NORTHEASTWARD MOVEMENT OF THE MID-LEVEL SYSTEM. AS THIS
OCCURS...DEEPENING UPPER TROUGHING OVER THE WESTERN CONUS ON ALL
MODELS AND ENSEMBLE SYSTEMS SHOULD DRIVE HEIGHTS HIGHER OVER THE
EASTERN CONUS. IN RESPONSE...WARMER CONDITIONS SHOULD BECOME MORE
COMMON. HOWEVER...THE DEGREE OF RIDGING OVER THE REGION IS NOT
PARTICULARLY WELL AGREED UPON...PARTICULARLY TOWARD THE MIDDLE OF
NEXT WEEK. THIS COULD LEAVE THE AREA OPEN TO INSTABILITY
ENCROACHING FROM THE SOUTHWEST WITH RETURN FLOW FROM THE GULF. DUE
TO THIS POSSIBILITY...CHANCES OF SHOWERS REMAIN IN THE
FORECAST...HOWEVER TEMPERATURES STILL SEEM LIKELY TO REMAIN NEAR
OR ABOVE NORMAL. FRIES

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
SHOWERS AND THUNDERSTORMS HAVE GENERALLY REMAINED NORTH OF THE
PITTSBURGH METRO AREA. CONDITIONS ARE GENERALLY EXPECTED TO REMAIN
VFR...WITH MVFR A POSSIBILITY IN THUNDERSTORMS. MODEL GUIDANCE SHOWS
FKL/DUJ DROPPING TO IFR OVERNIGHT WITH LOWER CIGS. WITH FRONT
REMAINING IN THE VICINITY...CANNOT RULE THIS OUT...AND HAVE BROUGHT
THOSE TAFS DOWN TO LOWER CONDITIONS. GENERAL CONFIDENCE REMAINS
LOW...CONSIDERING MODELS ARE STILL HAVING A HARD TIME GETTING A
HANDLE OF WHERE THE FRONT IS LOCATED. OUTSIDE OF
FKL/DUJ...CONDITIONS WILL REMAIN VFR OVERNIGHT AND INTO THURSDAY.
RAIN SHOULD GENERALLY REMAIN TO THE WEST OF TAF SITES THROUGH THE
END OF THE 18Z TAFS.

.OUTLOOK.../THURSDAY NIGHT THROUGH MONDAY/...
A COLD FRONT WILL MOVE ACROSS THE REGION THURSDAY NIGHT...BRINGING
THE POSSIBILITY OF RESTRICTIONS IN SHOWERS AND SCATTERED
THUNDERSTORMS. CIG RESTRICTIONS WILL REMAIN POSSIBLE AFTER THE
FRONTAL PASSAGE FRIDAY INTO SATURDAY IN NORTHWEST FLOW. CONDITIONS
SHOULD REMAIN VFR SATURDAY NIGHT AND SUNDAY AS HIGH PRESSURE RIDGE
BRIEFLY ENTERS THE REGION. A WEAK FRONT COULD BRING SOME SCATTERED
SHOWERS SUNDAY NIGHT INTO MONDAY.
