DISCUSSION
KEY MESSAGE 1: PROLONGED HAZARDOUS COLD THREAT CONTINUES INTO
THE WEEKEND
THE PEAK OF THE COLD IS APPROACHING WITH RECORD CHALLENGING
MINIMUM TEMPERATURES THIS MORNING AND TONIGHT/AM SATURDAY. WE
WOULD NOT BE SURPRISED TO SEE A FEW LOCAL OBSERVATIONS
(OVERNIGHT MINIMUM TEMPERATURES OR WIND CHILLS) GETTING CLOSE
TO EXTREME COLD CRITERIA. ADDITIONAL COLD WEATHER ADVISORIES ARE
PROBABLE FOR SATURDAY NIGHT. WE ARE INTO THE LATE INNINGS OF
THE PROLONGED HAZARDOUS COLD EVENT WHICH WILL COME TO AN END BY
GROUNDHOG DAY. TEMPERATURES ARE FORECAST MODERATE A BIT NEXT
WEEK, BUT IT WILL STILL BE COLD FOR THIS TIME OF YEAR WITH
HIGHS REMAINING BELOW THE FREEZING MARK IN MOST OF CPA.
KEY MESSAGE 2: WINDY START TO FEBRUARY
AS THE STORM PULLS AWAY FROM THE COAST ON SUNDAY, THE TIGHTENING
PRESSURE GRADIENT WILL RESULT IN WIND GUSTS OF 25-35 MPH ACROSS
THE AREA. A BRISK AND COLD START TO FEBRUARY.
KEY MESSAGE 3: ACCUMULATING SNOW POSSIBLE WEDNESDAY 2/4
NBM/NBMV5 ARE SIGNALING A BROAD AREA OF LIGHT SNOW ACCUMULATION
(1-3") ON WEDNESDAY FEB. 4TH. GEFS/EPS AND THEIR RESPECTIVE AI
ENSEMBLES SHOW SLIGHT DIFFERENCES WITH THE NORTH/SOUTH QPF
PLACEMENT AND TIMING/SPEED THAT CAN BE EXPECTED WITH A
DEVELOPING LOW PRESSURE SYSTEM AT THIS RANGE. WE WILL CONTINUE
TO TRACK THIS SYSTEM, BUT WANTED TO HIGHLIGHT THE POTENTIAL FOR
MINOR WINTER WEATHER/TRAVEL IMPACTS AROUND THE MIDDLE OF NEXT
WEEK.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
AS BEEN THE CASE THE LAST 2 NIGHTS, A NORTHWEST FLOW OF VERY
COLD AIR OVER THE GREAT LAKES AREA WILL MAKE FOR ANOTHER
NIGHT OF VERY THIN CLOUDS AT TIMES WITH FLURRIES, ESP. LATE
AS THE AIRMASS COOL. MOST LIKELY SPOTS FOR THIS WILL BE BFD
AND JST, BUT ALSO POSSIBLE AT UNV AND AOO. FURTHER EAST I
EXPECT HIGHER CLOUDS AND LESS CHANCE FOR THIS TYPE OF ACTIVITY.
LOOKING AT VFR CONDITIONS ON FRIDAY.
SOME CHANCE OF MORE THIN CLOUDS WITH FLURRIES AGAIN FRIDAY
NIGHT, GIVEN VERY COLD TEMPERATURES.
WEEKEND LOOKING TO REMAIN MAINLY DRY, BUT EXPECT WINDS TO PICK
UP ON SUNDAY, AS INTENSE COASTAL LOW DEEPENS TO OUR EAST AND
SOUTH.
LIKE SEVERAL MONDAY'S SO FAR THIS SEASON, WARM ADVECTION MAY
RESULT IN SOME LIGHT SNOW LATER MONDAY INTO EARLY TUE.
OUTLOOK...
SAT...PERIODS OF LAKE EFFECT AND UPSLOPE SNOW SHOWERS REMAIN
POSSIBLE ACROSS N/W PA, WITH RESTRICTIONS POSSIBLE; OTHERWISE,
CHILLY AND BREEZY AREAWIDE.
SUN...AROUND A 10 TO 20 PERCENT CHANCE OF LIGHT SNOW AT
LNS EARLY, OTHERWISE DRY. BECOMING WINDY, ESP. AT MDT
AND LNS.
MON...INCREASING CLOUDS, WITH A SLIGHT CHANCE OF LIGHT
SNOW LATE ACROSS THE NORTH AND WEST.
TUE...PERHAPS SOME PATCHY LIGHT SNOW EARLY AT BFD AND
JST, BUT MAINLY DRY.

STATE COLLEGE HAS A VERY GOOD SHOT OF TYING THE SECOND LONGEST
RUN (7) OF CONSECUTIVE DAYS WITH MAX TEMP <= 20F (1/25-1/31).
THE LAST TIME THIS OCCURRED WAS POST-CHRISTMAS 2017 (12-28-2017
TO 01-03-2018). THE LONGEST RUN OF 10 DAYS OCCURRED IN JANUARY
1893 FROM THE 11TH-20TH.
