AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
1253 PM EDT TUE APR 10 2012

.SYNOPSIS...
COLD NORTHWEST WINDS WILL KEEP THE RISK FOR SCATTERED RAIN OR
SNOW SHOWERS INTO WEDNESDAY. COLDER TEMPERATURES WILL HOLD ON
THROUGH THURSDAY MORNING.

&&

.NEAR TERM /THROUGH TONIGHT/...
STRATUS HAS OVERTAKEN LOCATIONS NORTH AND WEST OF
PITTSBURGH...WITH LOCATIONS SOUTH AND EAST STILL NEARLY OVERCAST
WITH BROKEN CUMULUS. HAVE HIGHLIGHTED AN ELEVATED FIRE RISK ACROSS
THE WV/MD RIDGES WITH SPECIAL WEATHER STATEMENT...WHERE CONDITIONS
ARE MARGINAL FOR RED FLAG WARNING CRITERIA. CONFIDENT THAT WIND
GUSTS WILL GO ABOVE CRITERIA...BUT RELATIVE HUMIDITY IS NOT
EXPECTED TO HIT CRITICAL VALUES. PRECIPITATION WILL INCREASE
THROUGH THE AFTERNOON HOURS WITH FLOW OFF LAKE ERIE. MODEL
SOLUTIONS ARE SOMEWHAT VARIED AS TO HOW MUCH THE SHOWERS WILL
PERSIST INTO THE OVERNIGHT HOURS...BUT WILL KEEP LIKELY POPS TO
THE NORTH. TEMPERATURES WILL DROP NEAR FREEZING TONIGHT...AND WILL
KEEP THE FREEZE WATCH IN EFFECT. THE TEMPERATURES SHOULD ALSO
ALLOW FOR SOME CHANGEOVER TO SNOW...BUT ASSUME THAT WARM GROUND
TEMPERATURES SHOULD PREVENT MUCH MORE THAN A DUSTING OF
ACCUMULATION.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
STRONG UPPER LOW IN EASTERN CANADA WILL BRING NORTHWEST WINDS
FOR THE UPPER OHIO VALLEY INTO WEDNESDAY NIGHT. RESULTING SURFACE
LAYER INSTABILITY WILL RESULT IN SCATTERED SHOWERS LINGERING INTO
WEDNESDAY AFTERNOON. UPSLOPE LIFT WILL CAUSE SHOWERS TO BE MORE
NUMEROUS NEAR THE MOUNTAINS AND I-80 CORRIDOR. HAVE ADDED CHANGE
TO SNOW SHOWERS DURING LATE NIGHT PERIODS WHEN SURFACE LAYER
TEMPERATURES GO BELOW MID 30S.

SNOW ACCUMULATION WILL BE MINIMAL FOR THE MOST PART. DAYTIME
HIGHS WEDNESDAY WILL BE NEARLY 15 DEGREES COLDER THAN NORMAL. LOW
TEMPERATURES CAN GO BELOW FREEZING.

BY THURSDAY, INCOMING HIGH PRESSURE WILL PROVIDE SUFFICIENT
SUBSIDENCE TO END REMAINING SHOWERS WEDNESDAY NIGHT AND DECREASE
CLOUDS BY DAYTIME THURSDAY. HENCE EXPECT TEMPERATURES TO REBOUND
THURSDAY WITH AFTERNOON HIGHS PERHAPS ONLY 5 AND 8 DEGREES COLDER
THAN NORMAL.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
THERE IS RELATIVELY DECENT MODEL AGREEMENT FOR THE BEGINNING OF THE
PERIOD AS THE DEEP LONG WAVE TROUGH LIFTS NORTHEASTWARD WITH MINUTE
DIFFERENCES IN THE SHORTWAVE STRENGTH WITHIN THE PATTERN THURSDAY
NIGHT. THIS HOWEVER...DOESN'T SEEM TO IMPACT THE MODEL PARAMETERS
TOO MUCH AS THE STRONGER ECMWF STILL KEEPS THE REGION DRY UNDER HIGH
PRESSURE.

THERE IS GREATER MODEL SPREAD TOWARDS THE LATTER HALF OF THE
PERIOD INTO THE WEEKEND AS SHORTWAVES BEGIN TO BREAK THE 500HPA
RIDGE DOWN. THE GFS SEEMS TO BE THE FASTEST WITH THE APPROACH OF A
SERIES OF LOW PRESSURE SYSTEMS...AS HPC HAS MENTIONED...SO OPTED
TO REMAIN CLOSE TO GUIDANCE WITH A HEAVIER EMPHASIS ON THE ECMWF
AND ENSEMBLES. THIS BROUGHT LOW CHANCE POPS INTO THE FORECAST
STARTING SATURDAY AND MAINTAINED THEM THROUGH MONDAY.

KEPT TEMPERATURES CLOSE TO HPC NUMBERS WHICH STRAY SLIGHTLY FROM MEX
GUIDANCE AND GRADUALLY INCREASE TO NEAR 5-10 DEGREES ABOVE NORMAL BY
MONDAY.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
VFR CONDITIONS WILL MOSTLY PREVAIL ACROSS THE TERMINALS TODAY AS AN
UPPER LEVEL LOW ACROSS EASTERN CANADA CONTINUES TO BRING A COOL,
NORTHWESTERLY FLOW TO THE REGION. CLOUDS AROUND 3500-4500FT WILL
DEVELOP AROUND 15Z, WITH WEST-NORTHWESTERLY WINDS INCREASING TO
10-15KTS WITH GUSTS AT 25-30KTS THROUGH EARLY THIS EVENING.

AN UPPER LEVEL DISTURBANCE WILL PUSH INTO THE AREA FROM THE
NORTH THIS AFTERNOON, INCREASING THE CHANCE OF SHOWERS. AS COOLER
AIR WITH THIS SYSTEM DIVES SOUTHWARD, THE CHANCE OF SHOWERS WILL
INCREASE TONIGHT, WITH RAIN CHANGING OVER TO SNOW SHOWERS.
MVFR SNOW SHOWERS ARE LIKELY AT KFKL/KDUJ WITH BRIEF PERIODS OF
IFR VISIBILITIES RESTRICTIONS NOT OUT OF THE QUESTION THERE.

OUTLOOK..WEDNESDAY THROUGH SATURDAY...
THE COOL NORTHWESTERLY FLOW WILL CONTINUE THROUGH WEDNESDAY NIGHT,
WITH THE CHANCE OF SHOWERS WITH MVFR RESTRICTIONS CONTINUING. HIGH
PRESSURE WILL THEN BUILD IN FROM THE WEST AND ALLOW FOR VFR
CONDITIONS TO PREVAIL FOR THE MAJORITY OF THURSDAY AND FRIDAY. A
WARM FRONT WILL PUSH INTO THE AREA ON SATURDAY AND RETURN THE CHANCE
OF SHOWERS.

...ENHANCED FIRE DANGER THIS AFTERNOON...

BREEZY WEST WINDS...LOW RELATIVE HUMIDITY...AND LOW FUEL STICK
MOISTURE WILL BRING AN ENHANCED THREAT FOR THE SPREAD OF WILDFIRES
THIS AFTERNOON. THIS WILL BE ESPECIALLY TRUE IN OPEN AREAS AND
ALONG EXPOSED RIDGETOPS.

OPEN BURNING OF ANY TYPE IS CONSIDERED VERY HAZARDOUS AT THIS TIME.
ACCIDENTAL ESCAPED DEBRIS BURNS ARE BY FAR THE NUMBER ONE CAUSE OF
WILDFIRES. ALSO...BE CAREFUL WITH HEAT AND SPARKS WHILE OPERATING
ANY EQUIPMENT...OR SMOKING IN WILDLAND AREAS.
