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

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

&&

.NEAR TERM /THROUGH TONIGHT/...
WITH 1030AM UPDATE...MADE CHANGES TO TEMPS AND POPS. EVEN HI-RES
MODELS ARE HAVING A HARD TIME FIGURING OUT THE CURRENT FRONTAL
LOCATION AND WHERE THE TIGHT TEMPERATURE GRADIENT LIES. ERIE
CURRENTLY HAS TEMPERATURE OF 44...WHILE MEADVILLE IS 63. ADJUSTED
HIGH TEMPS AS BEST AS POSSIBLE. IN ADDITION...MADE SLIGHT TWEAKS
TO TIMING OF POPS TODAY. HI-RES MODELS INDICATE THAT THUNDERSTORMS
COULD DEVELOP IN A LINE AND MOVE SOUTH DURING THE 18Z-21Z TIME
FRAME...WHICH WAS ALREADY REFLECTED IN POP GRIDS. PREVIOUS
DISCUSSION FOLLOWS.

FRONTAL BOUNDARY HAS EDGED SOUTH OVERNIGHT AND NOW LIES JUST NORTH
OF INTERSTATE 80 ACROSS PA. MAIN QUESTION FOR TODAY IS HOW FAR
SOUTH FRONT WILL PUSH AS SHORTWAVE MOVES EAST FROM THE GREAT LAKES
AND CONVECTION FIRES ALONG FRONT. HUGE TEMPERATURE GRADIENT ALONG
BOUNDARY AND FORECAST HIGHS WILL RANGE FROM UPPER 60S FAR NORTH
TO AROUND 80 FAR SOUTH BUT AMOUNT OF SKY COVER ACROSS THE SOUTH
WILL BE CRITICAL TO MAX TEMPS. WITH TEMPERATURES STILL QUITE WARM
THIS MORNING ACROSS THE SOUTH DID NOT MAKE ANY MAJOR CHANGES TO
PREVIOUS FORECAST TEMPS. SPC HAS MUCH OF AREA IN SLIGHT RISK WITH
STRONG UNIDIRECTIONAL WIND PROFILE. ELEVATED CONVECTION EXPECTED
NORTH OF FRONT WITH LARGE HAIL POSSIBLE. AMOUNT OF LOW LEVEL
INSTABILITY SOUTH OF FRONT IS IN QUESTION AS MID LEVEL CLOUDS
ALREADY ACROSS OHIO MOVING EAST MAY LIMIT AMOUNT OF SURFACE CAPE
THAT CAN BE REALIZED. FOR NOW KEPT HIGHEST POPS NORTH OF
PITTSBURGH WITH CHANCE POPS SOUTH.

FRONT WILL STALL AGAIN TONIGHT AND THEN SHIFT NORTH AGAIN THURSDAY
MORNING AHEAD OF APPROACHING DEEP UPPER TROUGH/CLOSED LOW MOVING
TOWARD OHIO VALLEY. TRIED TO KEEP CONTINUITY WITH PREVIOUS
FORECAST FOR TIMING OF POPS WITH MAIN COLD FRONT THEN REACHING THE
REGION LATER THURSDAY AND CROSSING UPPER OHIO VALLEY FRIDAY.
SHOWERS AND STORMS LIKELY ACROSS PITTSBURGH AND NORTH THIS
EVENING THEN TAPER OFF LATER TONIGHT INTO EARLY THURSDAY AS FRONT
SHIFTS NORTH.

&&

.SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/...
CAT POPS AS THURSDAY NIGHT PROGRESSES INTO FRIDAY WITH FROPA.
TEMPERATURES WILL REMAIN ABOVE NORMAL UNTIL FRIDAY AFTER FRONT.
SLIGHT RISK OF SEVERE AGAIN WITH MAIN FRONT BUT OVERNIGHT
THURSDAY/EARLY MORNING FRIDAY TIMING LOOKS TO LIMIT INSTABILITY.

WITH RECENT DRY ANTECEDENT CONDITIONS NOT EXPECTING RAINFALL TO BE
ABLE TO PRODUCE ANY FLOOD PROBLEMS ALTHOUGH WHERE STORMS POSSIBLY
TRAIN ALONG FRONT HEAVY RAINFALL POSSIBLE.

MUCH COLDER FRIDAY NIGHT INTO SATURDAY IN NORTHWEST FLOW BEHIND
THE FRONT. WITH 850MB TEMPS FALLING TO -5C TO -7C SCATTERED
SHOWERS REMAIN IN FORECAST AND A FEW SNOWFLAKES MAY MIX IN AS WELL
FAR NORTH AND RIDGES EARLY SATURDAY MORNING.

&&

.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 /18Z WEDNESDAY THROUGH MONDAY/...
VFR CONDITIONS ARE EXPECTED THROUGH THE FORECAST PERIOD. A
STALLED FRONTAL BOUNDARY...OVER PA/NY BORDER...SHOULD KEEP ANY
OVERNIGHT ACTIVITY TO THE NORTH.

LATER THIS MORNING AND CONTINUING THROUGH THE AFTERNOON...A SERIES
OF UPPER LEVEL WAVES WILL SWEEP THROUGH THE UPPER OHIO VALLEY. THIS
ENERGY WILL BRING BKN-OVC CU AND ALSO THE RISK FOR SHOWERS/STORMS.
LATEST HI-RES MODEL DATA IS INDICATING A LINE OF SHOWERS DEVELOPING
FROM WEST TO EAST LATE THIS MORNING AND CONTINUING INTO LATE
AFTERNOON. CONFIDENCE IS NOT HIGH IN RESPECT TO THESE SHOWERS
DEVELOPING SO WILL INCLUDE A PERIOD OF NON-RESTRICTIVE RAIN SHOWERS
LATER TODAY. IT IS NOT OUT OF THE REALM OF POSSIBILITY THAT
RESTRICTIONS...WITH LOWER CLOUDS AND THUNDERSTORMS...COULD DEVELOP
THIS AFTERNOON...BUT AT THIS POINT CONFIDENCE IS TOO LOW TO MENTION
IN CURRENT FORECAST.

.OUTLOOK.../WEDNESDAY NIGHT THROUGH SUNDAY/...
FRONT WILL REMAIN PARKED JUST TO THE NORTH OF THE AREA INTO
THURSDAY. A SERIES OF UPR LVL WAVES WILL CONTINUE THE RISK FOR
SHOWERS AND STORMS AT ANY TIME . A CDFNT IS EXPCTD TO MOVE ACRS
THE RGN LT THU AND THU NGT WITH SHRA/TS RESTRICTIONS PSBL. CIG
RESTRICTIONS WL REMAIN PSBL AFT FROPA INTO SAT IN NW FLOW.
