NWS State College, PA wrote its last area forecast discussion before the first event at Feb 26, 2:30 AM EST, 4 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 230 AM EST TUE FEB 26 2008 .SYNOPSIS... A STORM SYSTEM WILL TRACK ACROSS THE SOUTHERN THIRD OF PENNSYLVANIA TODAY AND TONIGHT...SPREADING MORE WINTRY WEATHER ACROSS THE REGION. MUCH COLDER AIR WILL ARRIVE IN THE STORMS WAKE TONIGHT AND WEDNESDAY AND LAST FOR THE SECOND HALF OF THIS WEEK. SNOW IS EXPECTED STATEWIDE FRIDAY NIGHT INTO SATURDAY AS A STORM TRACKS ACROSS THE NORTHERN GREAT LAKES INTO NORTHERN NEW ENGLAND TO START THE MONTH OF MARCH. && .NEAR TERM /UNTIL 11 AM THIS MORNING/... CURRENT ADVISORIES AND NARROW STRIPE OF WINTER STORM WARNINGS APPEAR WELL PLACED AT THIS HOUR. PRECIPITATION RAPIDLY OVERSPREADING WESTERN PA IN THE PREDAWN HOURS WITH MAINLY SNOW TO THE NORTH OF A KMFD TO KCAK LINE. KHLG SOME 50 MILES SOUTHWEST OF KPIT STARTED OUT WITH FZRA HOWEVER. NAM AND GFS FORECAST SOUNDINGS GO ISOTHERMAL UP AND DOWN THE ZERO LINE FOR SEVERAL HOURS THIS MORNING OVER THE CENTRAL MOUNTAINS BEFORE WARMING TO PRODUCE PLAIN RAIN ACROSS THE SOUTHERN HALF OF CENTRAL PA AFTER 15-18Z. NAM40 MIXED 1KM LAYER WET BULB BY 15Z DEPICTS THIS LINE QUITE WELL. THIS IS CURRENTLY WELL COVERED WITH LAST EVENINGS SOUTHWARD EXPANSION OF WINTER WEATHER ADVISORIES INTO THE LAURELS FOR NO CHANGES AT THIS TIME. && .SHORT TERM /11 AM THIS MORNING THROUGH WEDNESDAY NIGHT/... A STRIPE OF HEAVY SNOW IS EXPECTED ACROSS THE NORTHERN TIER COUNTIES WITH IN EXCESS OF 8 INCHES EXPECTED TO THE NORTH OF ROUTE 6. BIGGEST QUESTION IS HOW FAR SOUTH TO BRING THE HEAVY SNOW AREA. FEEL PRETTY SAFE IN KEEPING IT NORTH OF I-80...BUT AREAS SUCH AS KIPT WESTWARD TO DUBOIS COULD END UP WITH SEVERAL INCHES BEFORE THE DAY IS DONE. EXACT TRACK OF SFC LOW...ESP. IF IT ENDS UP NEAR OR SOUTH OF THE MASON DIXON...WOULD INCREASE THIS POTENTIAL. BUT...FOR NOW ALL AVAILABLE GUIDANCE SUGGESTS ENOUGH WARM AIR FLOODS NORTHWARD BELOW 850 MB TO CHANGE PRECIP OVER TO A PLAIN RAIN THIS AFTERNOON FROM I-80 SOUTHWARD...AND PERHAPS 50-100 MILES NORTH OF I-80. SO...CURRENT SNOW ACCUMS AND TIMING OF PRECIP CHANGEOVER LOOKS REASONABLE. WATER VAPOR IMAGERY SHOWS S/W TROF DIGGING INTO THE UPR MS VLY THIS AFTN...WITH HEIGHT FALLS PUSHING EWD ACROSS THE CNTRL PLAINS. LATEST 6HR PRES FALLS INDICATE THAT AN AREA OF LOW PRES WILL DEVELOP OVER SRN MO/NRN AR THIS EVE. MODELS ARE FINALLY COMING INTO AGREEMENT WITH REGARD TO THE TRACK OF THE THIS LOW...WHICH IS FCST TO INTENSIFY AS IT HEADS EWD THRU THE OH VLY ON TUE AND INTO THE GULF OF ME BY EARLY WED. GEFS/GEM/GFS/ECMWF ARE IN VERY GOOD AGREEMENT IN TAKING THE SFC LOW FM NRN KY AND INTO SE PA BTWN BY TUE EVE...WITH ONLY MINOR TIMING DIFFERENCES STILL NOTED. HPC PREFERS THE SLIGHTLY FASTER GFS SOLN VS. THE NAM...WHICH AS BEEN THE SLOWER MDL OF LATE WITH THIS SYS. THE GFS HAS SUPPORT FM THE GEM/ECMWF...AND MOST IMPORTANTLY THE GEFS MEAN. BROAD WARM ADVECTION PCPN WILL OVERSPREAD THE REGION DURING THE DAYLIGHT HOURS ON TUE AHEAD OF A STG SRLY LLJ. NAM/GFS THERMAL PROFILES VIA BUFKIT STILL INDICATE A BRIEF PD OF MIXED SN/FZRA/PL ACROSS THE CNTRL 1/3 OF THE CWA EARLY TUES...WITH MAINLY SNOW ACROSS THE FAR NRN TIER COUNTIES. HAVE ISSUED WINTER WX ADVY FOR SEVERAL COUNTIES ALONG AND JUST SOUTH OF I-80...WITH A SHOT OF WINTRY WX EARLY TUES BEFORE GOING TO A MIX OF RAIN/SNOW BY THE AFTN HOURS. A BRIEF PD OF FZRA IS PSBL ACROSS THE SRN TIER VERY EARLY TUE...BUT PRECIP WILL TRANSITION OVER TO PLAIN RAIN BY MID MORNING. CONFIDENCE IN ANY APPRECIABLE ICE ACCUMULATION IS VERY LOW ACROSS SRN PA...SO HAVE OPTED JUST TO COVER THIS IN THE HWO/ZFP. LATER SHIFTS WILL NEED TO MONITOR FOR PSBL FZRA ADVY AS ANY ICE AMTS WOULD ONLY BE A FEW HUNDREDTHS OF AN INCH. STILL EXPECTING A PERIOD OF MODERATE DEFORMATION BAND SNOW BY EARLY TONIGHT AS THE COLD AIR WRAPS BACK AROUND THE SFC LOW WHICH WILL EXIT SOUTHEAST PA THIS EVENING. LAKE EFFECT SNOWFALL WILL ALSO BE ON THE INCREASE LATER TONIGHT INTO WEDNESDAY AS -16C TO -20C AIR FLOWS OVR LKS HURON...ONTARIO AND ERIE LATE TONIGHT THROUGH WED AFTN. EVEN COLDER AIR WILL DROP SOUTH AND EAST OF THE LAKES BY THURSDAY MORNING...KEEPING LAKE EFFECT SNOW SHOWERS GOING INTO THURSDAY. && .LONG TERM /THURSDAY THROUGH MONDAY/... LATE WEEK TROUGH WILL BEGIN TO DEPART THE MID-ATLANTIC...AS WEAK MID-LVL RIDGING SLIDES EAST ON IT/S HEELS. RETURN WESTELRY FLOW WILL AID IN BRINGING A BRIEF WARM SURGE BACK INTO CENTRAL PA. GFS- ENSEMBLES PAINT DEEP LAYERED RH LATE WEEK...WHICH COULD PRODUCE SOME DECENT PRECIP. MODELED PROFILES INDICATE VARIED PRECIPITATION TYPES HALF INDICATING SNOW AND HALF INDICATING RAIN FOR THE LATE WEEK EVENT. WHERE IT SNOWS...SEVERAL INCHES ARE POSSIBLE. ANOTHER TROUGH WILL SWING THROUGH SUN...ALLOWING SFC RIDGE TO ONCE AGAIN SLIDE ACROSS SOUTHERN PORTIONS OF THE MID-ATLANTIC. ACTIVE PATTERN PERSISTS THROUGH FIRST HALF OF NEXT WEEK AS WAVE DIGS INTO THE CENTRAL PLAINS AND OHIO RIVER VALLEY MON. ATTM IT APPEARS SECOND WARM SURGE CONTINUES TO BE POISED TO ARRIVE MON...WITH PRECIP AT ONSET IN A LIQUID STATE. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... PERSISTENT STRATOCU DECK TRAPPED BENEATH INVERSION HAS KEPT CIGS GENERALLY BETWEEN 15-25 KFT FROM THE ALLEGHENY MTNS WESTWARD. LATEST IR IMAGERY SHOWS STRATOCU DECK ERODING FROM THE SOUTH...AS WARM AIR ADVECTION OVERSPREADS THE REGION. HOWEVER...AREAS OF HZ WILL KEEP SOME SPOTS IN THE MVFR CATEGORY THROUGH THE LATE EVENING HOURS. LOW PRESSURE APPROACHING FROM THE OHIO VALLEY WILL RESULT IN DETERIORATING FLYING CONDS EVERYWHERE BTWN 09-12Z...AS A WINTRY MIX OVERSPREADS THE AREA. PTYPE SHOULD TRANSITION TO RAIN ACROSS THE SOUTH BY MIDDAY...BUT REMAIN PREDOMINANTLY SNOW ACROSS THE NORTH. WIDESPREAD LIFR/IFR CIGS EXPECTED ACROSS THE ENTIRE AREA DURING THE DAYLIGHT HOURS OF TUESDAY. AS THIS STORM SYSTEM MOVES THROUGH WITH ASSOCIATED COLD FRONT TUES NITE...COLDER AND WINDIER CONDITIONS SWEEP IN BEHIND. WINDS WILL TURN W/NW AT 15-25 MPH WITH HIGHER GUSTS. ALSO BY TUE NIGHT WE TRANSITION TO A TYPICAL LAKE EFFECT REGIME WITH VFR IN THE EAST AND MVFR/IFR IN SNOW SHWRS ACROSS THE HIGHER ELEVATIONS OF THE W AND N. GUSTY NW WINDS EXPECTED TO CONTINUE IN THE WAKE OF THIS STORM WED AND THURS...CREATING LAKE EFFECT SNOW SHWRS OVR THE ALLEGHENY HIGHLANDS /KBFD AND KJST/...WHILE VFR CONDS LIKELY TO PREDOMINATE EAST OF THE MTNS. HIGH PRESSURE WILL BUILD ACROSS THE STATE THURS NITE...PROVIDING A PERIOD OF WIDESPREAD LIGHT WINDS/VFR CONDS. A STORM SYSTEM PASSING TO OUR NORTH COULD BRING DETERIORATING FLYING CONDS LATE FRIDAY AND EARLY SATURDAY...ESPECIALLY OVR THE ALLEGHENY HIGHLANDS /BFD AND JST/. && .CTP WATCHES/WARNINGS/ADVISORIES...
