AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
258 PM EST SAT NOV 15 2008

.SYNOPSIS...
A COLD FRONT PASSING THROUGH THE AREA THIS EVENING WILL CHANGE
RAIN SHOWERS TO SNOW LATER TONIGHT AND SUNDAY, WITH LIGHT SNOW
ACCUMULATIONS IN THE RIDGES AND NORTHWEST PENNSYLVANIA SNOW BELT.
BELOW NORMAL TEMPERATURES WILL CONTINUE WITH SNOW SHOWERS MONDAY
AND TUESDAY.

&&

.NEAR TERM /THROUGH SUNDAY/...
JUDGING FROM BLEND OF RECENT SURFACE DATA AND SREF MODEL RUNS EXPECT
POSTSYSTEM WRAPAROUND PRECIPITATION BAND TO MOVE THROUGH THE UPPER
OHIO VALLEY TONIGHT. WESTERLY SURFACE LAYER WINDS SHOULD MAINTAIN
UPSLOPE INSTABILITY SHOWERS SUNDAY.

REGARDING WIND SPEEDS...NAM PROFILES AND ISALLOBARIC FORECASTS SHOW
WINDS CAN GUST TO ABOUT 25 KTS TONIGHT AND SUNDAY.

REGARDING PRECIPITATION TYPE...NAM PROFILES ALSO SHOW SUFFICIENT
COOLING TO LOWER THE FREEZING LEVEL INTO THE SURFACE BOUNDARY LAYER
LATE TONIGHT. HENCE THERE CAN BE A TRANSITION TO LIGHT SNOW SHOWERS
BEFORE DAYBREAK SUNDAY. HOWEVER LITTLE IF ANY SNOW ACCUMULATION IS
EXPECTED DAYTIME SUNDAY DUE TO GFS AND NAM MOS VALUES SHOWING ACTUAL
SURFACE TEMPERATURES AND LIKEWISE GROUND TEMPERATURES REMAINING
ABOVE FREEZING THIS PERIOD.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
RECENT SREF MODEL RUNS SHOW WESTERLY SURFACE LAYER WINDS CAN STILL
MAINTAIN UPSLOPE INSTABILITY SHOWERS SUNDAY NIGHT WITH SMALL
ACCUMULATIONS OF SNOW OVER THE HIGHER MOUNTAINS. EXPECT LOW
TEMPERATURES IN THE 20S AS INDICATED BY BLEND OF GFS AND NAM MOS.

FLOW WILL TURN TO THE NORTHWEST ON MONDAY...WITH A BROAD TROUGH OVER
THE EASTERN UNITED STATES. EXPECT LAKE EFFECT TO HEAD INLAND OFF
LAKE ERIE DURING THE AFTERNOON. PRECIPITATION WILL THEN BE ENHANCED
BY A SHORTWAVE THAT THE NAM/GFS/ECMWF ALL SHOW PASSING OVER THE
SOUTHWESTERN PORTION OF THE CWA MONDAY NIGHT. IT APPEARS THAT ALL
LOCATIONS IN THE FORECAST AREA WILL RECEIVE SNOWFALL AS THIS SYSTEM
MOVES THROUGH...ALTHOUGH MOST LOCATIONS WOULD ONLY SEE AN INCH OR
TWO OF ACCUMULATION. SNOW AMOUNTS WILL LIKELY BE SOMEWHAT
LIMITED...AT LEAST INITIALLY...BY WARM GROUND TEMPERATURES. EXPECT
TO SEE HIGHER AMOUNTS IN THE RIDGES AND ESPECIALLY IN THE ALLEGANY
PLATEAU. IT APPEARS THAT A WATCH LIKELY WILL NEED TO BE ISSUED BY
THE MIDNIGHT SHIFT ALONG THE WEST VIRGINIA-MARYLAND BORDER. FLOW
WILL REMAIN OUT OF THE NORTH-NORTHWEST INITIALLY TUESDAY
MORNING...BUT WILL BACK DURING THE AFTERNOON HOURS AND BRING AN END
TO LAKE EFFECT PRECIPITATION.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
HIGH PRESSURE OVER THE MISSISSIPPI VALLEY WILL MOVE NORTH TUESDAY
NIGHT...BRINGING SOUTHWESTERLY FLOW AND A BRIEF END TO LAKE EFFECT
SNOWS. AFTER THIS A WEAK LOW PRESSURE SYSTEM WILL DROP SOUTHEAST
OVER THE GREAT LAKES...BRINGING ANOTHER CHANCE OF LAKE EFFECT. HIGH
PRESSURE LATE IN THE WEEK WILL RESULT IN CONTINUED NORTHERLY FLOW.
WITH SUCH AN UNSETTLED PATTERN...WEDNESDAY APPEARS TO BE THE ONLY
DAY WITH THE POTENTIAL TO BE DRY. TEMPERATURES WILL CONTINUE TO BE
WELL BELOW NORMAL...WITH ONLY A SLIGHT POSSIBILITY OF SEEING
TEMPERATURES RISE INTO THE 40S.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
BLEND OF RECENT SURFACE AND RADAR DATA ALONG WITH SREF MODEL RUNS
SHOW POSTSYSTEM WRAPAROUND PRECIPITATION MAINTAINING A POTENTIAL FOR
IFR CEILINGS INTO TONIGHT. AS WINDS BECOME SOUTHWESTERLY EXPECT
GUSTS TO NEAR 25 KTS TONIGHT. SURFACE LAYER TEMPERATURES WILL COOL
SUFFICIENTLY SO THAT THE FREEZING LEVEL WILL LOWER INTO THE SURFACE
LAYER WHICH WILL ALLOW A TRANSITION TO SNOW SHOWERS LATE TONIGHT.

EXPECT MAINLY MVFR CONDITIONS SUNDAY AND SUNDAY NIGHT DUE TO
WESTERLY WINDS ADVECTING COLD AND UNSTABLE AIR UPSLOPE ACROSS THE
UPPER OHIO VALLEY. AFTER A SECOND COLD FRONT MOVES THROUGH DAYTIME
MONDAY THERE CAN BE PERIODS OF IFR CONDITIONS AS SURFACE LAYER WINDS
BECOME NORTHWEST AND BRING EVEN COLDER AIR ACROSS LAKES HURON AND
ERIE INTO THE UPPER OHIO VALLEY AND UP AGAINST THE APPALACHIAN
MOUNTAINS. RECENT GEFS MODEL RUNS SUGGEST CONTINUED LAKE ENHANCED
COLD AIR MVFR STRATOCUMULUS AND SCATTERED IFR INSTABILITY SNOW
SHOWERS WEDNESDAY AND THURSDAY.
