AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
732 AM EDT THU JUL 5 2012

.SYNOPSIS...
NORTHWEST WINDS ALOFT WILL CONTINUE TO BRING POTENTIALLY SEVERE
THUNDERSTORMS SOUTHEASTWARD FROM MICHIGAN AND LAKE ERIE TODAY.
BROAD HIGH PRESSURE WILL MAINTAIN HOT HUMID CONDITIONS INTO THE
WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
HAVE MAINTAINED SEVERE THUNDERSTORM WATCH FOR SEVERAL NORTHERN
COUNTIES, PLUS ADDED MENTION OF STRONG WIND AND HAIL WITH
THUNDERSTORMS FURTHER SOUTH, AS ONE OR TWO MORE THUNDERSTORM
COMPLEXES MOVE SOUTHEASTWARD THROUGH THE UPPER OHIO VALLEY TODAY,
ONE THIS MORNING AND THE SECOND THIS AFTERNOON, PER RECENT RADAR
DATA AND HRRR MODEL OUTPUT.

HAVE ALSO MAINTAINED HEAT ADVISORY FOR MOST LOWER ELEVATION
COUNTIES, AS HEAT INDICES WILL PEAK NEAR 100 THIS AFTERNOON. OF
COURSE, THUNDERSTORM PASSAGES MAY CUT INTO THAT, BUT THAT IS THE
POTENTIAL.

FORECASTED TEMPERATURES AND DEW POINTS TODAY BASED ON BLEND OF
RECENT HRRR, GFS LAMP, NAM AND GFS MOS VALUES.

EXPECT SKIES TO BE PARTLY TO MOSTLY SUNNY TODAY, DEPENDING ON
MOVEMENT OF MCS, WITH A BIT LESS HUMIDITY, BUT HOT TEMPERATURES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/...
MID-WESTERN RIDGE WILL MOVE EASTWARD AND BUILD INTO THE UPPER
OHIO VALLEY FRIDAY, MEANING THE HOTTEST AIR WILL SHIFT EASTWARD.
WITH LOTS OF SUNSHINE FRIDAY, AND HIGHER TDS SLOWLY MAKING A
RETURN, EXPECT ANOTHER HOT AND HUMID DAY FRIDAY.

RIDGE BEGINS TO BREAK DOWN FRIDAY NIGHT AND SATURDAY AS A SERIES
OF UL WAVE MOVE ACROSS THE GREAT LAKES. MODELS ARE SHOWING A SFC
FRONT MOVING INTO THE NORTH SATURDAY MORNING AND DRIFTING
SOUTHWARD THROUGHOUT THE DAY. WILL NEED TO BRING POPS BACK IN ON
SATURDAY WITH THE UL WAVES AND SFC FRONT. STILL ANOTHER HOT AND
HUMID DAY SAT.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
THERE IS GFS/ECMWF ENSEMBLE AGREEMENT TO BEGIN THE PERIOD THAT DEEP
RIDGING WILL BE CENTERED ACROSS THE MISSOURI VALLEY. THE UPPER OHIO
VALLEY WILL BE IN A NORTHWESTERLY FLOW ON THE EASTERN PERIPHERY OF THE
RIDGE. THE MODEL CONSENSUS INDICATES AN AMPLIFYING TREND WITH THE
RIDGE DOMINATING THE WESTERN TWO THIRDS OF THE CONUS AND LOWERING
MID-LEVEL HEIGHTS ACROSS THE UPPER OHIO VALLEY AS A TROUGH BUILDS
INTO THE NORTHEAST.

AFTER A COLD FRONT DROPS SOUTHEAST ACROSS THE AREA AND BRINGS
CHANCE POPS ON SUNDAY, A DRIER AND COOLER FORECAST IS IN PLACE FOR
EARLY NEXT WEEK. HAVE GONE DRY OR WITH SILENT SLIGHT CHC POPS FOR
LOWERING HEIGHTS THROUGH WEDNESDAY. UNCERTAINTY ENTERS THE FORECAST
BY NEXT THURSDAY WITH THE POTENTIAL OF A MID-LEVEL TROUGH PUSHING
FROM THE UPPER MIDWEST SOUTHEASTWARD ACROSS THE AREA. TEMPS ARE
AROUND 5 DEGREES ABOVE NORMAL AHEAD OF THE FRONT ON SUNDAY.
TEMPERATURES WILL THEN LOWER TO NEAR SEASONABLE VALUES FOR MONDAY,
TUESDAY AND WEDNESDAY.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
CURRENTLY WATCHING MCS OVER LOWER MI. HAVE LOW CONFIDENCE ON HOW
WELL THIS WILL HOLD TOGETHER, OR WHERE IT WILL END UP GOING.
HOWEVER, WITH ITS GENERAL DIRECTION, AND TAKING INTO ACCOUNT WHERE
ACTIVITY DEVELOPED LAST NIGHT, WILL NEED TO INCLUDE A TEMPO GROUP
OF MVFR RESTRICTIONS WITH STORMS AT FKL AND DUJ THIS MORNING. IF
COMPLEX HOLDS TOGETHER, WILL NEED RESTRICTIONS IN PORTS FURTHER
SOUTH. ONCE THIS COMPLEX MOVES THROUGH A GENERAL VFR FORECAST FOR
THE REST OF THE DAY.

SFC WINDS WILL SHIFT LATER THIS MORNING FROM A SOUTHWESTERLY
DIRECTION TO A NORTHERLY DIRECTION AND INCREASE IN SPEED TO AROUND
10 TO 15KTS.

OUTLOOK...THURSDAY NIGHT THROUGH MONDAY...
VFR EXPECTED, EXCEPT FOR MORNING MVFR HAZE. RESTRICTIONS WILL ALSO
BE POSSIBLE IN SCATTERED THUNDERSTORMS LATE SATURDAY AND AGAIN ON SUNDAY
AS A FRONT MOVES SOUTHWARD THROUGH THE REGION. VFR CONDITIONS
WILL RETURN ON MONDAY.
