FRIDAY...
...WIND CHILL WARNING REMAINS IN EFFECT FROM 6 PM THIS EVENING TO
12 PM EST SATURDAY...

A WIND CHILL WARNING REMAINS IN EFFECT FROM 6 PM THIS EVENING TO
12 PM EST SATURDAY. A LAKE EFFECT SNOW ADVISORY REMAINS IN EFFECT
UNTIL 7 AM EST FRIDAY. 

AS A STORM SYSTEM PASSES SOUTH OF PENNSYLVANIA EARLY TODAY...
WINDS WILL TURN NORTHWESTERLY OFF LAKE ERIE CREATING NUMEROUS
SNOW SHOWERS AND THE POTENTIAL FOR NARROW BANDS OF LAKE EFFECT
SNOW.

ADDITIONAL SNOW ACCUMULATIONS OF 4 TO 6 INCHES WILL BE POSSIBLE
ACROSS THE FAR NORTHWEST PART OF THE COUNTY OVER THE UPCOMING
18 TO 24 HOURS...WITH LESSER AMOUNTS OF 1 TO 3 INCHES OVER MUCH
OF THE AREA TO THE SOUTH OF ROUTE 6.

THE NORTHWEST WINDS OF 10 TO 15 MPH WITH GUSTS AROUND 20 MPH WILL
COMBINE WITH BITTERLY COLD AIR TO PRODUCE WIND CHILLS OF 15 TO
20 BELOW ZERO FROM LATE TODAY...RIGHT THROUGH SATURDAY MORNING.
SOME LOCATIONS WILL SEE THE WIND CHILLS DIP TO AROUND 25 BELOW
ZERO FOR BRIEF PERIODS AT NIGHT.

A WIND CHILL WARNING MEANS THE COMBINATION OF VERY COLD AIR AND
STRONG WINDS WILL CREATE DANGEROUSLY LOW WIND CHILL VALUES. FROST
BITE...HYPOTHERMIA OR EVEN DEATH ARE POSSIBLE IF THOSE VENTURING
OUTSIDE DO NOT TAKE THE PROPER PRECAUTIONS. WEAR MULTIPLE LAYERS
OF WARM...LOOSE FITTING CLOTHING. TRAPPED AIR BETWEEN THE LAYERS
WILL INSULATE YOU. OUTER GARMENTS SHOULD BE TIGHTLY WOVEN TO
SHIELD THE WIND. A HOOD OR HAT IS ESSENTIAL...AS HALF YOUR BODY
HEAT CAN BE LOST FROM YOUR HEAD.

A LAKE EFFECT SNOW ADVISORY MEANS LAKE-EFFECT SNOW IS FORECAST
THAT WILL MAKE TRAVEL DIFFICULT IN SOME AREAS. LAKE-EFFECT SNOW
TYPICALLY FALLS AS NARROW BANDS OF HEAVY SNOW WITHIN A LARGER
AREA OF LIGHTER SNOWFALL. GIVEN THE NATURE OF LAKE EFFECT SNOW...
VISIBILITIES CAN BECOME REDUCED VERY RAPIDLY...SOMETIMES TO NEAR
ZERO OVER ONLY A SHORT DISTANCE. PLAN ON EXTRA TRAVEL TIME
BECAUSE CONDITIONS WILL REQUIRE YOU TO SLOW DOWN. STAY TUNED TO
NOAA WEATHER RADIO OR YOUR FAVORITE SOURCE OF WEATHER INFORMATION
FOR THE LATEST UPDATES. ADDITIONAL DETAILS CAN ALSO BE FOUND AT...
 WEATHER.GOV/STATECOLLEGE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
637 PM EST WED JAN 14 2009

.SYNOPSIS...
AN ALBERTA CLIPPER STORM SYSTEM RACING THROUGH THE OHIO VALLEY
THIS AFTERNOON...WILL MOVE EAST ALONG THE MASON-DIXON LINE
TONIGHT BRINGING A PERIOD OF LIGHT SNOW TO MUCH OF THE REGION.
THE COLDEST AIR OF THE SEASON WILL FOLLOW FOR THURSDAY AND FRIDAY.
TEMPERATURES WILL MODERATE SLIGHTLY OVER THE WEEKEND...BUT WILL
STILL REMAIN SEVERAL DEGREES BELOW NORMAL. ANOTHER CLIPPER SHOULD
BRING SOME LIGHT SNOW SATURDAY INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
CLOUDS CONTINUE TO INCREASE AHEAD OF OF OUR CLIPPER SYSTEM.
REGIONAL RADAR MOSAICS SHOW PRECIP FROM WESTERN PA INTO INDIANA.
SURFACE OBSERVATIONS SHOW SEVERAL STATIONS WITH 3-STAR SNOW...WITH
VISIBILITIES MAINLY IN THE 1/2 TO 2 MILE RANGE.

MODELS AND ENSEMBLES STILL SHOW GOOD AGREEMENT WITH THE TRACK OF
THE CLIPPER LOW...ALONG OR JUST SOUTH OF THE MASON-DIXON LINE.
BASED ON CLIMATOLOGY AND EXPERIENCE...THIS IS A FAVORABLE TRACK
FOR A SWATH OF MAINLY LIGHT SNOW...WITH SOME EMBEDDED HEAVIER
AMOUNTS ACROSS CENTRAL PA NORTH OF THE LOW TRACK. SREF PLUME DATA
SHOWS BETWEEN .15 AND .20 INCHES QPF ON AVERAGE OVER WESTERN AND
CENTRAL AREAS. FCST SOUNDINGS SHOW A NICE CROSS HAIR SIGNATURE
WITH STRONG UPWARD VERT MOTIONS THROUGH THE MOIST CLOUD LAYER
BETWEEN -14 TO -16C...WHICH SHOULD YIELD SNOW RATIOS OF AT LEAST
15 OR 20 TO 1. THIS WILL SUPPORT A GENERAL 2 TO 4 INCH
ACCUMULATION TONIGHT FROM THE LAUREL HIGHLANDS EWD INTO THE
CENTRAL MOUNTAINS. OROGRAPHIC LIFT MAY RESULT IN SLIGHTLY HIGHER
SNOW TOTALS OVER THE LAURELS...IN THE 3 TO 5 INCH RANGE. WILL
CONTINUE THE CURRENT ADVISORY...AND EXPAND IT TO THE NORTH AND
EAST BY A FEW COUNTIES TO COVER THE INCREASED AREA OF FLUFFY
SNOW EXPECTED.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
AFTER SOME LINGERING LIGHT SNOW SHOWERS ACROSS THE CENTRAL AND
EASTERN ZONES THURSDAY MORNING...A TRANSITION TO A WESTERN/NRN
MOUNTAINS SNOW SHOWER/LAKE EFFECT REGIME WILL OCCUR AS A
PERSISTENT MEAN SFC-850 MB WIND OF 285-295 DEG DEVELOPS. THE
LAKE EFFECT WATCH IS UP FROM 12Z THURS BUT AM NOT CONVINCED THINGS
CAN OR WILL SET UP THAT EARLY OVER THE NW MOUNTAINS. WOULD
NORMALLY BE THINKING OF ISSUING SOME SORT OF WARNING OR ADVISORY
WITH THIS UPCOMING PACKAGE BUT WILL INSTEAD KEEP THE WATCH GOING
WITH THE IDEA THAT THE BEST CHANCE FOR LAKE EFFECT TO SET UP WILL
PROBABLY NOT BE UNTIL LATER IN THE DAY AND OVERNIGHT THURS INTO
FRI.

NO REAL REASON TO QUIBBLE WITH POTENTIAL AMOUNTS...WITH 24 HOUR
SNOW TOTALS FROM ABOUT 2-5 INCHES ACROSS CENTRAL AND SOUTHERN
PORTIONS OF WARREN AND MCKEAN COUNTIES...TO AROUND 10 INCHES
ACROSS THE FAR NORTH (AND WRN WARREN CTY).

NUMEROUS SNOW SHOWERS WILL BRING LIGHTER ACCUMS 1 TO 4 INCHES
ACROSS MUCH OF THE ALLEGHENY PLATEAU AND LAUREL HIGHLANDS...WITH
FLURRIES AND ISOLATED/SCATTERED SNOW SHOWERS ACCOUNTING FOR AT
MOST 0.5 TO 1 INCH ACROSS THE CENTRAL MTNS AND MIDDLE SUSQ VALLEY.

NORTHWEST WINDS OF 10 TO 20 MPH AND GUSTY WILL COMBINE WITH STEADY
TO SLOWLY FALLING TEMPS THURSDAY AFTERNOON TO CREATE WIND CHILLS
OF 5 TO 10 BELOW ZERO BY THURSDAY AFTERNOON ACROSS THE NRN AND
WRN MTNS.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
NOT LOOKING QUITE AS COLD NOW OR WINDY FOR THE PERIOD THU INTO
SAT MORNING. DID EDGE TEMPS UP A FEW DEGREES HERE AND THERE.
WIND CHILL ADVISORY VALUES NOT REALLY MET UNTIL LATE THU... THUS
MAINLY AFTER THE SECOND PERIOD. THUS HELD OFF ON AN ADVISORY FOR
NOW. WE DO CLIP WIND CHILL WARNING VALUES BY A DEGREE OR SO LATER
THU NIGHT AND FRIDAY NIGHT ACROSS THE FAR N. HOWEVER...IF
MODERATION TREND CONTINUES...WE MAY NOT REACH THE MINUS 25
WARNING THRESHOLD. THUS HELD OFF ON WIND CHILL WATCH FOR NOW.

SOME SHEAR FOR LAKE EFFECT...BUT THE EXTREMELY COLD AIR
WILL PASS ACROSS THE WARMER LAKES...AND GIVEN HOW COLD THE
AIRMASS IS...UPSLOPE WILL HELP ADD TO THE SNOW. THUS A
LAKE EFFECT WATCH LOOKS GOOD FOR NOW.

SMALL WARM UP SETS IN ON SATURDAY INTO SUNDAY. STILL THINK
HIGH OVER QUEBEC IS A HINT THAT LAKE ONTARIO WILL KEEP THE
REAL COLD AIR TO THE NORTH. THIS MAY RESULT IN THE NEXT
CLIPPER GOING FURTHER NORTH ON SUNDAY. THUS I DID NOT GO
REAL HIGH WITH QPF AMTS.

FCST GETS MORE COMPLICATED AS ONE GOES OUT IN TIME. DID NOT
CHANGE MUCH FOR MONDAY INTO TUE...TRIED TO KEEP BEST CHC OF
SNOW IN AREAS OF UPSLOPE FLOW.

BETTER CHC FOR CLEARING ON WED...AS WEAK RIDGE BUILDS IN.
ANOTHER POOL OF COLD AIR LIKELY TO BE JUST TO THE NORTH...
THUS WARM UP AFTER THIS MAY BE SLOWER THAN EXPECTED...
ESPECIALLY ACROSS THE NE PART OF THE CWA. HOWEVER...STILL
LOOKS LIKE AT LEAST A SMALL WARM UP FOR SEVERAL DAYS
LATER NEXT WEEK.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
SNOW SHIELD AHEAD OF LOW PRESSURE SYSTEM OVER OHIO IS MOVING
ACROSS CENTRAL PA ATTM. EXPECT WIDESPREAD IFR TO CONTINUE/DEVELOP THROUGH
THE EVENING HOURS AT MOST TAF SITES WITH VISIBILITIES BELOW 2
MILES MOST OF THE TIME. THE EXCEPTION WILL BE OVER SERN AREAS /MDT/KLNS/
WHERE THE SNOW WILL BE LIGHTER.

WE SHOULD TRANSITION INTO A POST-FRONTAL WESTERLY FLOW REGIME
THURS...MEANING MOST TERMINALS WILL RETURN TO VFR WITH JUST
SCATTERED SNOW SHOWERS BRINGING OCNL REDUCED CONDITIONS. AS
USUAL...JST/BFD WILL REMAIN THE WORST THE LONGEST DUE TO TERRAIN
AND LAKE-PROXIMITY ISSUES. THEY COULD STAY MVFR/IFR RIGHT THROUGH
FRIDAY.

HIGH PRESSURE BRINGS A BRIEF RESPITE FOR FRIDAY BEFORE ANOTHER
CLIPPER BRINGS SOME SNOW AND REDUCE CONDITIONS FOR LATER SATURDAY
INTO SUNDAY.
