AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
209 AM EDT THU APR 21 2011

.SYNOPSIS...
HIGH PRESSURE WILL PROVIDE DRY AND COOL CONDITIONS TODAY. RAIN
WILL RETURN EARLY FRIDAY AND CONTINUE THROUGHOUT THE WEEKEND.

&&

.NEAR TERM /THROUGH TODAY/...
WEATHER QUESTION TODAY IS HOW MUCH CLOUD COVER WILL DISSIPATE.
CURRENTLY SC DECK IS COVERING THE ENTIRE REGION, WITH HIGHER
CIRRUS CLOUDS RIDING OVER TOP OF THE DECK. THESE HIGH CLOUDS ARE
THE BLOW-OFF FROM THE DECAYING MCS WHICH IS MOVING THROUGH THE
CAROLINAS. THE OTHER MITIGATING FACTOR IS THAT THE UPPER OHIO
VALLEY WILL BE UNDER CAA THROUGH THE ENTIRE DAY, WITH A STRONG NW
FLOW IN THE MID LEVELS. CURRENT MODELS ARE SHOWING THAT DRYING IN
THE LOWER LEVELS WILL CONTINUE THROUGHOUT THE ENTIRE DAY WITH SFC
TDS FALLING INTO THE MID 20S BY LATE AFTERNOON. LATEST HRRR CIG
FORECAST SHOWS THE LOWER CLOUDS DISSIPATING THIS MORNING AND THE
CI DECK SHIFTING TO THE SE AS THE COMPLEX MOVES OUT TO SEA. FOR
THE FORECAST, WILL GO WITH A DECREASE IN CLOUDS THIS MORNING AND
THEN PS DURING THE AFTERNOON. THE APRIL SUN WILL KEEP THE T-TD
SPREAD ENOUGH SO THAT SC WILL NOT REFORM, BUT IT SHOULD BE ENOUGH
TO DEVELOP SOME CU IN THE NW FLOW ALOFT. TEMPS WILL BE TRICKY AS
WELL AS THE SUN THIS TIME OF THE YEAR IS STRONG ENOUGH TO PUSH SFC
TEMPS UP, EVEN WITH BKN CLOUD COVER. WILL STICK CLOSE TO 00Z
MAV/21Z SREF NUMBERS.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...
THE NEXT SYSTEM WILL APPROACH THE AREA TONIGHT, WITH A FRONTAL
BOUNDARY DRAPED ACROSS THE MID/UPPER OHIO VALLEY FRIDAY THROUGH
SATURDAY. MODELS VARY ON HOW FAR NORTH TO PUSH THE BOUNDARY, BUT
ARE IN RELATIVE AGREEMENT PUSHING SIGNIFICANT MOISTURE ACROSS THE
REGION. WILL STICK CLOSE TO PREVIOUS FORECAST NUMBERS WITH CHC
POPS LATE TONIGHT, AND CATEGORICAL POPS FRIDAY AND FRIDAY
NIGHT. MODELS CONTINUE TO SHOW A STABLE ATMOSPHERE UNTIL SAT, SO
WILL LEAVE OUT MENTION OF TSTMS UNTIL SAT. THIS WILL NEED TO BE
CLOSELY LOOKED AT IN FUTURE FORECASTS AS ELEVATED CONVECTION IS A
POSSIBILITY.
&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
FRONT WILL HOLD UP ACROSS THE FORECAST AREA FOR MUCH OF THE EXTENDED
PERIOD. A CHANCE OF SHOWERS WILL REMAIN IN THE FORECAST ALL THE WAY
FROM SATURDAY NIGHT THROUGH MONDAY NIGHT...WITH THUNDERSTORMS ALSO
POSSIBLE DURING THE AFTERNOON AND EVENING. THE FRONT SHOULD FINALLY
DISSIPATE TUESDAY...ALLOWING FOR A BRIEF DRY PERIOD. LOW PRESSURE
DEVELOPING IN THE CENTRAL PLAINS SHOULD THEN BRING A COLD FRONT ON
WEDNESDAY...REINTRODUCING POPS. WITH THE FRONT LYING MAINLY ACROSS
THE NORTHERN COUNTIES...THIS SHOULD KEEP SOUTHERLY FLOW AND ABOVE
NORMAL TEMPERATURES AT MOST LOCATIONS.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
STRONG PRESSURE GRADIENT CONTINUES ACROSS REGION AS SURFACE HIGH
OVER ILLINOIS BUILDS EAST. MVFR STRATUS WILL HAVE A FEW BREAKS BUT
WILL HAVE A TOUGH TIME BREAKING OUT IN NORTHWEST FLOW INTO EARLY
MORNING. DRIER AIR SHOULD BE ABLE TO MIX OUT STRATUS FOR A TIME
LATER THIS MORNING BUT WITH COLD ADVECTION EXPECT BKN VFR CIGS TO
REDEVELOP BY MID MORNING. GUSTY WEST TO NORTHWEST WINDS WILL
CONTINUE INTO LATE AFTERNOON. AS SURFACE HIGH CENTER REACHES REGION
THIS EVENING WINDS WILL SUBSIDE WITH VFR CONDITIONS.

SURFACE HIGH WILL SLIDE EAST LATER THURSDAY NIGHT WITH WINDS TURNING
NORTHEAST IN ADVANCE OF WARM FRONT ASSOCIATED WITH LOW PRESSURE
MOVING EAST FROM KANSAS FRIDAY. MID DECK WILL OVERSPREAD LATER
THURSDAY NIGHT WITH RESTRICTIONS DEVELOPING FRIDAY IN RAIN AND
CONTINUE INTO SATURDAY AS TRAINING COLD FRONT STALLS ACROSS REGION.
THIS FRONT WILL REMAIN NEARLY STATIONARY INTO MONDAY WITH POSSIBLE
RESTRICTIONS.

MD...NONE.
OH...NONE.
PA...NONE.
WV...NONE.
