AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
200 PM EST THU JAN 31 2008

.SYNOPSIS...

HIGH PRESSURE OVER THE UPPER OHIO RIVER VALLEY WILL MOVE INTO
NORTHERN NEW ENGLAND BY TONIGHT. MEANWHILE A STORM SYSTEM
GATHERING OVER THE GULF STATES WILL START TO MOVE NORTHEAST
TODAY...SPREADING A WINTRY MIX OF PRECIPITATION ACROSS THE
FORECAST AREA LATER TONIGHT AND FRIDAY.

IN THE WAKE OF THE STORM...DRIER AIR WILL PUSH INTO THE REGION
FROM THE WEST SATURDAY AND REMAIN THROUGH SUNDAY ALONG WITH ABOVE
NORMAL TEMPERATURES.

THE NEXT SYSTEM TO BRING PRECIPITATION TO THE REGION SHOULD BE
SOME TIME LATER MONDAY OR TUESDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...

CLOUDS WILL CONTINUE TO THICKEN OVERNIGHT WITH THE CONSENSUS OF
THE NEW GUIDANCE SUGGESTING PRECIP OVERSPREADING THE AREA BETWEEN
ABOUT 4 AND 7 AM. FORECAST SOUNDINGS SHOW SOME LIGHT SNOW POSSIBLE
AT THE ONSET OVER ONLY FAR NORTHERN AREAS. THE REMAINDER OF THE
FORECAST AREA WILL SEE SLEET OR FREEZING RAIN.

HAVE TRIED TO SHOW TEMPS OVERNIGHT REACHING THEIR MIN RELATIVELY
EARLY...THEN STEADY OR RISING AFTER MIDNIGHT.

&&

.SHORT TERM /FRIDAY/...

A VERY COMPLICATED FORECAST IS UNFOLDING FOR FRIDAY AS THE GULF
COAST STORM SPREADS A SWATH OF MDT-HVY PRECIP INTO THE REGION.

ANOMALY CHARTS POINT TO A RAPID SURGE OF MOISTURE ON THE NOSE OF A
50-70KT SSE LOW LEVEL JET. FORECAST PWATS SURGE TO 3-4 STD DEV
ABOVE NORMAL ON THE RAPIDLY DEVELOPING AND VERY EFFICIENT WARM
CONVEYOR BELT. AS ONE WOULD EXPECT...PROBABILITIES OF AN INCH OR
MORE OF PRECIP ARE SHOWN TO BE QUITE HIGH OVER VIRTUALLY ALL OF
THE AREA.

WHILE THE LARGE SCALE PATTERN AND INDICES ALL ARE SCREAMING FOR A
BIG EVENT...THE DETAILS WILL BE VERY TROUBLING AS SMALL VARIATIONS
IN TEMPERATURES WILL MEAN HUGE DIFFERENCES IN SENSIBLE WEATHER.
FORECAST SOUNDINGS SHOW A SLEET/FREEZING RAIN EVENT FOR THE MOST
PART OVER MUCH OF THE REGION EXCEPT THE FAR SOUTHEAST WHERE TEMPS
SHUD REBOUND RELATIVELY EARLY AND LIMIT ICE ACCRETIONS. ELSEWHERE
THE LOW LEVEL COLD AIR WILL BE PRETTY TENACIOUS WITH HIGHS
EXPECTED TO REBOUND ONLY INTO THE MID 30S TO AROUND 40 IN SOME
AREAS.

THE TWO BIGGEST PLAYERS TOMORROW THAT WILL DETERMINE THE IMPACT
ON THE REGION WILL BE THE TEMPS...EXACTLY WHEN/IF THEY NUDGE ABOVE
FREEZING...AND THE AMOUNT OF SLEET THAT RESULTS. WHILE WE HAVE
SEEN IN THE PAST BIG IMPACTS FROM HEAVY SLEET...THIS IS RARE AND
GENERALLY SLEET CAUSES FEWER PROBLEMS AS IT TENDS NOT TO STICK TO
TREES AND POWER LINES. SO AREAS THAT REBOUND ABOVE FREEZING EARLY
WILL SEE THE LOCAL IMPACTS MINIMIZED...AS WILL AREAS WHERE SLEET
DOMINATES OVER FREEZING RAIN AS THE MAIN PRECIP TYPE.

AT THIS TIME WE FEEL THE BEST CHANCE FOR A REAL HIGH IMPACT
WEATHER EVENT WILL BE CENTERED AROUND THE MORNING COMMUTE AS TEMPS
WILL BE NEAR OR BELOW FREEZING OVER MOST OF THE STATE. UNFORTUNATELY
ITS IMPOSSIBLE TO PIN DOWN THE DETAILS OF EXACTLY WHO WILL HAVE
RAIN/SLEET OR FREEZING RAIN AT THIS TIME...BUT THE BEST CHANCE OF
THE MORNING COMMUTE SEEING JUST PLAIN RAIN AND ABOVE FREEZING
TEMPS WILL BE OVER MY FAR SOUTHEASTERN COUNTIES. EVEN IN THE
HARRISBURG AREA INDICATIONS ARE THAT TEMPS WILL BE COLD ENOUGH
BETWEEN 6 AND 9 AM TO POSE AN ICING HAZARD.

THE GOOD NEWS PART OF ALL THIS IS THAT WE SHOULD SEE CLOUDS
THICKEN UP RATHER EARLY TONIGHT. THIS WILL LIMIT THE AMOUNT OF
RADIATIONAL COOLING THAT WILL HAVE TO BE OVERCOME TOMORROW.
HOWEVER WHILE WE SHOULDNT COOL EXCESSIVELY OVERNIGHT...THE
AIRMASS IS VERY DRY SO A SIGNIFICANT AMOUNT OF EVAPORATIVE COOLING
CAN BE EXPECTED AS THE PRECIP INVADES THE REGION.

THE BULK OF THE PRECIP WILL FALL BETWEEN 12-18Z WITH THE POTENTIAL
FOR SOME SIGNIFICANT ICE ACCUMS. THE BEST CHANCE OF THIS WILL BE
FROM ABOUT I-80 NORTHWARD.

NEW ENSEMBLE PLUMES AND 12Z OPERATIONAL BUFKIT DATA ALL POINT TO
MOST LOCATIONS SEEING ICE ACCUMS ON THE ORDER OF 2 TO 4 TENTHS.

COORDINATED WITH SURROUNDING WFOS AND WILL BE UPGRADING MUCH OF
THE WATCH TO A WINTER STORM WARNING...WITH A WEATHER ADVISORY FOR
THE LOWER SUSQ VALLEY.

AM NOT AS CONCERNED WITH STRONG DAMAGING SOUTHERLY GUSTS AS I WAS
THIS TIME YESTERDAY. WE TRADITIONALLY HAVE A HARD TIME MIXING
STRONG WARM ADVECTION WINDS DOWN TO THE SURFACE WHEN WE ARE COLD
AIR DAMMED. THE LOW LEVEL NORTHERLY AGEOSTROPHIC CIRCULATION OF
THE RETREATING UPPER JET ENTRANCE REGION WILL HELP SUPPORT HOLDING
THE COLD AIR IN PLACE AND PROVIDE AN EFFECTIVE BARRIER TO THE
STRONG WINDS OVER ALL BUT PERHAPS OUR RIDGE-TOPS. IF SOME
CONVECTION MANAGES TO FORM ALONG THE COLD FRONT...WHICH BY CURRENT
INDICATIONS COULD MOVE THRU OUR FAR EASTERN COUNTIES AS THE
SURFACE LOW MOVES THRU THE STATE...THEN WE MIGHT MANAGE TO SUPPORT
SOME STRONG GUSTS. BUT THAT TOO IS IMPOSSIBLE TO CALL AT THIS HOUR
AND WILL HAVE TO BE HANDLED AS A SHORT TERM ISSUE TOMORROW.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
THE LOW (WELL AGREED UPON OPERATIONAL MODELS AND SREF TO BE ABOUT
1002 TO 1004 HPA) LIFTS QUICKLY NE OF THE REGION AFTER 00Z WITH
STEADY PRECIP TAPERING TO SNOW AND RAIN SHOWERS DURING THE LATE
AFTERNOON (SW) AND EARLY EVENING (NE COUNTIES). CLOUDY SKIES WITH
A BRISK WEST WIND AND SCATTERED SHOW SHOWERS WILL OCCUR ACROSS
MUCH OF THE AREA FRIDAY NIGHT...WITH PERHAPS A LIGHT ACCUMULATION
FROM MORE NUMEROUS SNOW SHOWERS ACROSS THE NW MTNS. A FEW FLURRIES
WITH PARTIAL CLEARING WILL OCCUR ACROSS THE LOWER SUSQ VALLEY.

ANOTHER AREA OF HIGH PRESSURE WILL MOVE NE FROM THE OHIO VALLEY
FOR THE UPCOMING WEEKEND WITH PARTLY TO MOSTLY SUNNY SKIES AND
TEMPS SEVERAL DEG (OR MORE) ABOVE NORMAL.

ADDITIONAL MOISTURE FROM THE SOUTHWEST LOOKS TO INVADE THE REGION
BY MONDAY...REMAINING UNSETTLED INTO MID-WEEK. ABOVE NORMAL TEMPS
AND STORM TRACK FROM THE SRN PLAINS TO OHIO VALLEY OR UPPER GLAKES
FAVORS MAINLY RAIN TUESDAY AND WEDNESDAY WITH MAX AND MIN TEMPS
8-12F ABOVE NORMAL MONDAY THROUGH WEDNESDAY.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...

VFR CONDITIONS WILL CONTINUE MUCH OF THE NIGHT BEFORE WE SEE
PRECIP AND MOISTURE OVERSPREAD THE REGION LATE AT NIGHT. EXPECT
CEILINGS TO LOWER TO MVFR/IFR TOWARD DAWN AS A WINTRY MIX OF
SNOW/SLEET AND FREEZING RAIN DEVELOPS.

FRIDAY SHOULD SEE CEILINGS IN THE 500-1000 RANGE FOR THE MOST
PART WITH VISIBILITIES OF 1-3 MILES COMMON IN RAIN/FREEZING RAIN
OR SLEET. OTHER THAN LOW CEILINGS AND VIS...A BIG AVIATION PROBLEM
WILL BE THE POTENTIAL FOR SIGNIFICANT ICING. THING HARRISBURG WILL
WARM ABOVE FREEZING RELATIVELY EARLY IN THE DAY...BUT ALL OTHER
TERMINALS COULD SEE SEVERAL HOURS OF FREEZING PRECIP LASTING INTO
THE LATE MORNING OR EVEN AFTERNOON.

THE WEEKEND WILL SEE HIGH PRESSURE MAKE A RETURN WITH MAINLY FAIR
SKIES. WESTERN AND NORTHERN AREAS COULD SEE LOW CLOUDS AND SNOW
SHOWERS LINGER INTO SATURDAY...BUT THE TREND OVERALL WILL BE FOR
IMPROVEMENT. THE NEXT CHANCE OF CONDITIONS WORSENING WILL BE
LATER MONDAY AND TUESDAY WITH APPROACH OF ANOTHER FRONTAL SYSTEM.
