AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
145 PM EDT SUN JUN 3 2012

.SYNOPSIS...
UPPER LEVEL LOW PRESSURE ACROSS THE NORTHEASTERN UNITED STATES
WILL KEEP OCCASIONAL SHOWERS AND SLIGHTLY BELOW NORMAL
TEMPERATURES IN THE FORECAST FOR MUCH OF THE WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
UPDATED FOR MINOR ADJUSTMENTS TO SKY COVER THIS AFTERNOON. UPPER LEVEL LOW
HAS REMAINED NEARLY STATIONARY NORTH OF LAKE HURON OVERNIGHT. THIS
WILL BEGIN TO MOVE TO THE SOUTHEAST DURING THE MORNING
HOURS...NEARING LAKE ERIE BY THIS EVENING. WITH THE COMBINATION OF
STEEPENING LOW LEVEL LAPSE RATES...INSTABILITY VALUES BETWEEN
500-1000 J/KG...AND REACHING CONVECTIVE SURFACE
TEMPERATURES...SHOWERS ARE EXPECTED TO DEVELOP ALONG WITH
SCATTERED THUNDERSTORMS. FREEZING LEVELS ARE RELATIVELY
LOW...WHICH COULD RESULT IN GRAUPEL/SMALL HAIL. IN ADDITION...LOW
FREEZING LEVELS WILL ALLOW WINDS AT THE TOP OF THE BOUNDARY LAYER
TO REACH 40-50 KTS...WHICH COULD ALSO RESULT IN GUSTY WINDS. HAVE
ADDED BOTH THE SMALL HAIL AND GUSTY WINDS MENTION TO AREAS WITH
HIGHER POPS. SPC HAS PLACED MOST OF THE REGION IN A 'SEE TEXT'
MENTION FOR TODAY/S CONVECTIVE OUTLOOK. HAVE ALSO SEEN FAIRLY GOOD
AGREEMENT IN PLACEMENT OF LINE OF SHOWERS WITH 00Z HIGH-RES NCEP
NMM/ARW ALONG WITH 00Z NSSL ARW AND 00Z NAM NEST...SO HAVE TRIED
TO TIME THIS LINE OUT DURING THE LATE AFTERNOON HOURS. WITH
PRECIPITATION GENERALLY DIURNALLY DRIVEN...HAVE BROUGHT ALL POPS
TO AN END BY MIDNIGHT. HIGH TEMPERATURES SHOULD RANGE FROM THE MID
60S NORTHEAST TO THE MID 70S SOUTHWEST...WHICH FOLLOWS THE
EXPECTED SKY COVER GRADIENT.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
ALTHOUGH UPPER LEVEL LOW WILL MOVE ACROSS NEW ENGLAND ON
MONDAY...ITS INFLUENCE WILL REMAIN ACROSS THE REGION. NAM/GFS/ECMWF
ALL HAVE SOLID AGREEMENT SHOWING ANOTHER SHORTWAVE ENTERING THE
NORTHERN COUNTIES DURING THE EARLY AFTERNOON AND MOVING SOUTH
THROUGHOUT THE DAY. THIS SHOULD SET OFF ANOTHER ROUND OF SCATTERED
SHOWERS...BUT UNLIKE TODAY...SLIGHT CHANCES IN THE TEMPERATURE
PROFILE WILL ALLOW FOR LESS INSTABILITY AND THEREFORE NO
THUNDERSTORMS. BY TUESDAY...MODELS BEGIN TO SHOW DISAGREEMENT FOR
TIMING OF SHORTWAVES...SO HAVE GONE WITH MORE GENERIC CHANCE POPS.
THROUGHOUT THE TIME PERIOD...SHOWERS SHOULD BE DIURNALLY DRIVEN...SO
HAVE GONE WITH DRY CONDITIONS MONDAY AND TUESDAY NIGHTS.
TEMPERATURES WILL REMAIN SLIGHTLY BELOW NORMAL UNDER THE INFLUENCE
OF THE UPPER LOW.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
UPPER FLOW BLOCK IS NAEFS/ECMWF-FORECAST TO MAINTAIN EASTERN
CONUS TROUGHING FOR THE REMAINDER OF THE WORK WEEK. COOL
TEMPERATURES MAY BE ANTICIPATED...BUT CONFIDENCE IN PRECIP
FORECAST IS MINIMAL AS SHORTWAVES IN FLOW WILL DEFINE MOISTURE
SUPPLY AND BOUNDARY POSITIONING.

FOR NOW...WILL MAINTAIN SLIGHT CHANCE...TO CHANCE POPS FOR THE
LONG TERM PERIOD...WITH THE HIGHER NUMBERS OVER THE EASTERN
COUNTIES WHERE LOWER CONVECTIVE TEMPERATURES CAN BE ANTICIPATED
UNDER COOLER MID LEVELS.

EARLY RETURNS FOR NEXT WEEKEND INDICATE THAT THE AFOREMENTIONED
TROUGH SHOULD BEGIN FILLING...RESULTING IN MODERATING TEMPERATURES.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE ACROSS THE
TERMINALS THIS AFTERNOON INTO THE EARLY EVENING AS A SURFACE LOW
PASSES NORTH OF THE AREA. BRIEF MVFR RESTRICTIONS WILL BE POSSIBLE
WITH SHOWERS AND STORMS. TEMPO GROUPS FOR THUNDERSTORMS ARE
FORECAST ACROSS THE TERMINALS STARTING ACROSS THE NORTH AT
KFKL/KFKL THIS AFTERNOON AND BECOMING MORE ORGANIZED AS THEY
SHIFT SOUTHWARD ACROSS THE PITTSBURGH METRO AND INTO KMGW BY
EVENING. A FEW OF THE STORMS MAY HAVE STRONG WINDS AND SMALL HAIL.

SHOWERS AND STORMS WILL DIMINISH QUICKLY AFTER SUNSET WITH VFR
CONDITIONS PREVAILING OVERNIGHT.

.OUTLOOK...MONDAY THROUGH FRIDAY...
AN UPPER LEVEL LOW WILL REMAIN OFF THE COAST OF NEW ENGLAND MONDAY
THROUGH THURSDAY, ALLOWING FOR AT LEAST A SLIGHT CHANCE OF SHOWERS
WITH BRIEF RESTRICTIONS EACH AFTERNOON, ESPECIALLY FOR LOCATIONS
EAST OF KPIT. OTHERWISE VFR CONDITIONS WILL PREVAIL THROUGH THIS
PERIOD. HIGH PRESSURE BUILDING INTO THE AREA ON FRIDAY BRING AN
END TO AFTERNOON SHOWERS WITH VFR CONDITIONS CONTINUING.
