AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
742 AM EDT WED AUG 27 2014

.SYNOPSIS...
WARM TEMPERATURES WILL PERSIST THROUGH THE WEEK. A SHOWER OR STORM
WILL BE POSSIBLE TODAY AS A WEAK COLD FRONT PASSES THROUGH.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
NO SGFNT CHGS FOR THE ERLY MRNG UPDT. PREVIOUS DISC...A WEAK COLD
FRONT WILL SLOWLY CROSS THE AREA TODAY. LITTLE UPPER LEVEL SUPPORT
WILL PREVENT MUCH PRECIPITATION AS THE FRONT WILL BE RUNNING INTO
AN EASTERN RIDGE. ATMOSPHERE REMAINS RATHER STABLE THROUGH MUCH OF
THE MORNING...BUT WILL DESTABILIZE AS AFTERNOON APPROACHES. THIS
WILL BE IN RESPONSE TO THE HIGHER SURFACE DEW POINTS WHICH WILL
NOSE IN ALONG THE BOUNDARY LATER THIS MORNING. WITH THIS INCREASE
IN BUOYANCY...LOOKS LIKE THE BEST PLACE FOR ACTIVITY WOULD BE
ACROSS THE THE FAR SOUTH THIS AFTERNOON. WITH DAYTIME
HEATING...CONVECTION MAY QUICKLY DEVELOP ALONG A LINE OF LOW LEVEL
FORCING AND MOISTURE CONVERGENCE ON EITHER SIDE OF THE MASON-DIXON
LINE.

EXPECT A RANGE OF TEMPS TODAY FROM NORTH TO SOUTH.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
FRONT WILL BE WELL SOUTH OF THE AREA BY THIS EVENING...AS AN UPPER
LEVEL PUSH FINALLY ARRIVES. COULD SEE SOME LINGERING SHOWERS/
STORMS IN THE FAR SOUTH WITH THE UPPER LEVEL WAVE...BUT THESE WILL
END QUICKLY. COOLER...DRIER AIR WILL DIVE SOUTHWARD TONIGHT.

BROAD SURFACE HIGH WILL KEEP THE AREA DRY AND COMFORTABLE THROUGH
FRIDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
LONG TERM STILL LOOKING WARM...HUMID AND ACTIVE. AT THIS POINT...
MODEL DISCREPANCIES MAKE IT DIFFICULT TO PINPOINT A TIME PERIOD OR
LOCATION FOR THE HIGHEST PROBABILITY OF CONVECTION. BUT AT THIS
POINT...WOULD THINK SUNDAY AFTERNOON WITH THE PASSAGE OF ANOTHER
BOUNDARY.

&&
