AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
815 PM EST TUE JAN 22 2013

.SYNOPSIS...
A PERSISTENT NORTHWEST FLOW OF ARCTIC AIR CROSSING THE GREAT
LAKES...REINFORCED BY CLIPPER SYSTEMS...WILL CONTINUE TO BRING
VERY COLD TEMPERATURES AND LAKE EFFECT SNOWS TO THE REGION THROUGH
MID-WEEK. TWO AREAS OF LOW PRESSURE MOVING EAST FROM THE UPPER
MIDWEST AND TENNESSEE VALLEY WILL BRING THE CHANCE OF LIGHT TO
MODERATE SNOW ACCUMULATIONS TO THE AREA LATER FRIDAY INTO SATURDAY.
THE COLD PATTERN WILL LINGER INTO THE WEEKEND WITH SOME MODERATION
POSSIBLE BY EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A BLYR FLOW OFF OF LK ERIE OF ARND 270 DEGREES IS KEEPING BULK OF
LAKE EFFECT ACTIVITY NORTH OF THE BORDER. WEB CAMS FROM WARREN CO
SHOW LITTLE SNOW HAS FALLEN WITH ACCUMS OF ONLY ARND AN INCH.
HOWEVER...CONVERGENCE UPLIFT EAST OF LK ERIE SHOULD CONTINUE TO
PRODUCE SNOW OF VARYING INTENSITY ACROSS THE SNOWBELT OF NW WARREN
CO OVERNIGHT AND EXISTING HEADLINES LOOK GOOD TO CONTINUE AS
IS...ALONG WITH WIND CHILL ADVISORIES FOR THE ENTIRE ALLEGHENY
PLATEAU. A BLEND OF THE LATEST HI-RES MDL QPF SUPPORTS ADDITIONAL
OVERNIGHT ACCUMS ACROSS NW WARREN CO OF UP TO 4 INCHES.

PRES GRADIENT WILL REMAIN FAIRLY TIGHT ACROSS CENTRAL PA
OVERNIGHT...RESULTING IN A CONTINUATION OF THE BREEZY CONDS. HAVE
RAISED THE WGUSTS TO ARND 20KTS OVERNIGHT BASED ON 18Z MDL
SOUNDINGS. TEMP FCST SHOULD BE PRETTY STRAIGHT FORWARD GIVEN THE
WELL MIXED BLYR. MINS EXPECTED TO RANGE FROM ARND ZERO ACROSS THE
ALLEGHENY PLATEAU...TO ARND 10F OVER THE LOWER SUSQ VALLEY.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
COLDEST AIR WILL BE RETREATING ON WEDNESDAY...BUT PERSISTENT LAKE
FLOW REGIME WILL KEEP FLURRIES AND SNOW SHOWERS GOING ACROSS THE
NORTH. A WEAK CLIPPER DROPS THROUGH THE CENTRAL GLAKS WED
AFTERNOON AND MAY ENHANCE ACTIVITY ACROSS THE NORTH OR EVEN INDUCE
A NORTHWARD DRIFT TO EXISTING LAKE BANDS (FROM WEAK WAA AHEAD OF
THE CLIPPER). OVERALL...EXPECT -SHSN FROM APPROACHING SYSTEM TO
HOLD OFF UNTIL AFTER DARK.

WED MAXES SHOULD MAY BE A COUPLE OF DEG WARMER THAN TODAY WITH
LESS WIND OVERALL.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
THU STILL LOOKS TO BE THE BEST DAY OF THE NEXT SEVERAL...MAINLY
DRY,

SYSTEM FOR FRIDAY IS STILL SLOWER...THUS ADJUSTED FCST SOME
FOR THU NIGHT.

ALSO NORTHERN BRANCH OF THE FLOW IS THE STRONGEST. THE SOUTHERN
LOW PRODUCES SOME DECENT WARM ADVECTION...BUT MOISTURE IS
LIMITED. THUS LEFT SNOWFALL AMTS ABOUT THE SAME FOR FRIDAY...
BUT DID CUT BACK FOR FRIDAY NIGHT...AS SYSTEM RACES OFF THE
COAST.

WHILE 850 MB TRACK COULD SUPPORT A LITTLE SLEET NEAR THE
MD BORDER...LEFT OUT...GIVEN HOW COLD THE AIRMASS IS.

OVERALL...ABOUT 1 TO 2 INCHES OF SNOW FROM THE EVENT...
NOT HARD TO DO...AS IT WILL NOT BE A DENSE SNOW...THAT
WE HAD LAST WED AM.

SOME LAKE EFFECT FOR SAT...BUT WILL CUT OFF BY SUNDAY...
GIVEN RISING HEIGHTS...AND DIRECTIONAL SHEAR.

DID NOT GO REAL HIGH WITH TEMPS NEXT WEEK...OR VERY
WET...HARD TO SEE A MAJOR WARM UP AT THIS POINT.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
A PERSISTENT NORTHWEST FLOW OF ARCTIC AIR CROSSING THE GREAT
LAKES WILL CONTINUE TO BRING LAKE EFFECT SNOW TO PARTS OF THE
REGION THROUGH MID-WEEK.

ACTIVE SNOW SHOWERS ARE IN A LULL OVER NW PA LATE THIS EVE AS SFC
WINDS TURN MORE WESTERLY. HOWEVER MVFR CIGS AT JST AOO AND SOME
LOWERED VSBYS IN HZ AT BFD...PROBABLY BLOWING SNOW...REMAIN A
CONCERN. EXPECT MVFR TO LCL IFR AT KBFD TONIGHT...MVFR TO VFR CIGS
EXPECTED OVER THE LAUREL HIGHLANDS.

VFR CONDS WILL PREVAIL ELSEWHERE IN DOWNSLOPE FLOW WITH CLEAR
SKIES OVER FAR EAST AND PSBLY CENTRAL AIRFIELDS. WEST WINDS WILL
CONTINUE TO DECREASE OVERNIGHT...TURNING SWRLY BY DAYBREAK AHEAD OF
APPROACHING SHORTWAVE/CLIPPER SYSTEM.

OUTLOOK...

THU PM-FRI...MVFR/IFR BECOMING LIKELY IN LIGHT SNOW.

FRI NIGHT-SAT...SHSN WITH MVFR/OCNL IFR W MTNS...SCT SHSN IN MVFR
CENTRAL MTNS...PRIMARILY VFR SE.

SUN...VFR.
