NWS State College, PA wrote its last area forecast discussion before the first event at Jan 4, 8:00 PM EST, 5 hours earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE STATE COLLEGE PA 800 PM EST SUN JAN 4 2004 .UPDATE... COMPLEX WEATHER OCCURRING ACROSS CENTRAL PA TONIGHT. LARGE SWATH OF MOISTURE MOVING ACROSS THE ENTIRE STATE...WITH TEMPERATURES DROPPING ACROSS THE NORTHERN TIER COUNTIES. MIXED PRECIP HAS BEEN FALLING THERE...WITH RAIN FURTHER SOUTH. HOWEVER...WITH NORTHERLY AGEOSTROPHIC WIND COMPONENT INTENSIFYING OVERNIGHT...I AM CONCERNED THAT NEAR FREEZING LOW-LEVEL TEMPS WILL SLIDE SOUTHWARD INTO CENTRAL COUNTIES AS WELL. SOUNDING PROFILES SHOWING COLDER TEMPS AT HIGHER ELEVATIONS UP TO ABOUT 2500 FEET. SINCE MIXED PRECIP WILL LIKELY OCCUR /INCLUDING THE POSSIBILITY OF FZRA/ IN THESE AREAS AND ESPECIALLY ACROSS THE HIGHER ELEVATIONS...THE CURRENT WINTER WEATHER ADVISORY WILL BE EXPANDED SOUTHWARD. STRONG FRONTOGENESIS COMBINED WITH ISENTROPIC LIFT WILL CONTINUE TO PROVIDE FORCING FOR HEAVY PRECIPITATION ACROSS THE NORTHERN HALF OF THE CWA OVERNIGHT...AND CURRENT RADAR TRENDS REFLECT THIS. JOHNSTOWN ASOS REPORTED 0.50 INCHES IN PAST 6 HOURS...WITH MORE PRECIP ON THE WAY. THEREFORE...I WILL ADD CAMBRIA COUNTY TO FLOOD WATCH. ETA/GFS DIFFER WITH RESPECT TO EXACT SFC LOW TRACK...BUT AGREE ON LAGGING PRECIP INTO MONDAY MORNING...WHILE DELAYING THE ONSET OF COLD ADVECTION. AS A RESULT...I WILL INCREASE POPS ACROSS MOST OF THE AREA TOMORROW MORNING...AND DELAY CHANGE-OVER TO SNOW SHOWERS UNTIL LATE MORNING WEST...AND AFTERNOON IN CENTRAL AREAS. VILLANI && .PREV DISCUSSION... OVERRUNNING PCPN WILL CONTINUE TONIGHT OVER MOST OF CWA AS SFC LOW MOVES ACROSS OH VALLEY TOWARDS PA. EXPECT MOST OF PCPN TO BE IN THE FORM OF RAIN...SOME OF WHICH MAY BE HEAVY AT TIMES ESPECIALLY OVER NRN SECTIONS TO THE NORTH OF THE DEVELOPING WARM FRONT. ALONG THE NRN TIER COUNTIES ENOUGH COLD AIR HAS FILTERED SOUTH TO CAUSE MIX OF PCPN TYPES THROUGHOUT THE DAY. EXPECT TEMPERATURES TO REMAIN MARGINAL OVERNIGHT WITH CONTINUED MIX OF FREEZING AND NON FREEZING PCPN. THUS HAVE EXTENDED WINTER WEATHER ADVISORY THROUGH MON MORNING FOR COMBINATION OF ICE AND SNOW. CONTINUED RAINS ONTO NEARLY SATURATED SOILS HAS ALSO PROMPTED ISSUANCE OF FLOOD WATCH FOR NRN HALF OF CWA...WHICH WILL CONTINUE THROUGH MONDAY MORNING AS WELL. EXPECT SIG PCPN TO END FROM WEST TO EAST PRIOR TO NOON TIME MON AS SFC MOVES INTO ERN PA. AS COLDER AIR MOVES IN BEHIND THE SYSTEM LINGERING PCPN WILL CHANGE TO SOME SNOW SHOWERS IN THE NW AND SNOW FLURRIES MAINLY OVER THE CENTRAL CWA...THOUGH CAN NOT RULE OUT A FEW FLURRIES REACHING THE LOWER SUSQ. THE LONG RANGE FCST CONTINUES TO LOOK VERY COLD (AND COMPARATIVELY DRY) FROM MID WEEK ON AS LONG WAVE TROF SWEEPS EASTWARD. HPC PROGS SHOW WEAK SRN STREAM TROF/SFC WAVE WORKING ITS WAY ACROSS THE SE STATES THUR/FRI. ADDED MENTION OF CHANCE SNOW FOR FRI...BUT MUCH TOO SOON TO PLAY UP ANY POTENTIAL. GARTNER/LA CORTE && .CTP WATCHES/WARNINGS/ADVISORIES... PA...FLOOD WATCH THROUGH MONDAY MORNING FOR NORTHERN HALF OF CTP CWA AND CAMBRIA COUNTY. WINTER WEATHER ADVISORY THROUGH EARLY MONDAY MORNING FOR WARREN...MCKEAN...POTTER...TIOGA...ELK...CAMERON...CLINTON...LYCOMING ...SULLIVAN...CLEARFIELD...CENTRE...UNION...SNYDER...NORTHUMBERLAND.. .MONTOUR...COLUMBIA...SCHUYLKILL. &&

THIS EVENING UNTIL SHORTLY AFTER MIDNIGHT...HEAVIER PRECIPITATION IS EXPECTED WITH TEMPERATURES STILL HOVERING JUST A FEW DEGREES BELOW THE FREEZING MARK ACROSS THE NORTHWEST AND NORTH CENTRAL MOUNTAINS. THIS SCENARIO WILL SET THE STAGE FOR A POTENTIAL OF SIGNIFICANT FREEZING RAIN..WITH BETWEEN ONE QUARTER AND ONE HALF INCH OF ICE ACCUMULATION POSSIBLE TONIGHT BEFORE THE PRECIPITATION TAPERS OFF EARLY MONDAY. FREEZING RAIN PRODUCES A GLAZING OF ICE ON TREES...POWER LINES...AND UNTREATED ROADS AND SIDEWALKS. IF SIGNIFICANT ICE ACCUMULATES...POWER OUTAGES AND BROKEN TREE LIMBS MAY RESULT. ANOTHER ELEMENT FROM THIS STORM TO MONITOR WILL BE MODERATE TO HEAVY RAINFALL AMOUNTS OF ONE...TO ONE AND ONE HALF INCHES. THIS AMOUNT OF RAIN WILL LEAD TO SIGNIFICANT RISES ON AREA RIVERS AND STREAMS TO NEAR BANKFULL IN SOME PLACES. SHOULD THE RAINFALL AMOUNTS BECOME HEAVIER...A FLOOD WATCH MAY BE ISSUED. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY: THE COLDEST AIR OF THE SEASON SO FAR...WILL MOVE INTO THE STATE DURING THE MID AND LATE WEEK PERIOD DAYTIME TEMPERATURES WONT CLIMB OUT OF THE TEENS ACROSS THE NORTHERN THIRD OF THE STATE WEDNESDAY AND THURSDAY. SPOTTER CALL TO ACTION STATEMENT... SPOTTERS...PLEASE REPORT SIGNIFICANT ICE ACCUMULATION OF GREATER THAN ONE QUARTER OF AN INCH...AND SNOW ACCUMULATION GREATER THAN 3 INCHES. LAMBERT
