AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
1048 AM EDT THU MAR 19 2015

.SYNOPSIS...

HIGH PRESSURE OVER PENNSYLVANIA TODAY WILL PROVIDE FAIR AND DRY
WEATHER. LOW PRESSURE WILL TRACK ACROSS THE SOUTHERN MID ATLANTIC
STATES AND BRING A LATE SEASON SNOWFALL TO THE AREA ON FRIDAY. A
STRONG COLD FRONTAL PASSAGE SATURDAY NIGHT WILL REINFORCE COLD AIR
AND BELOW NORMAL TEMPERATURES INTO THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...

HIGH PRESSURE WILL PROVIDE FAIR AND DRY WX ACROSS CENTRAL PA
THROUGH EARLY TONIGHT...THOUGH SUNSHINE WILL FADE BEHIND GRADUALLY
INCREASING MID AND HIGH CLOUDINESS STREAMING IN FROM THE WEST.

THE NEAR TERM UPDATE TWEAKED TEMPERATURES A BIT GIVEN LATEST
ENSEMBLE MOS NUMBERS. FCST HIGHS ARE STILL SEVERAL DEGREES BELOW
MID MARCH CLIMATE NORMALS...HOWEVER LIGHT WINDS AND SUNSHINE
WILL MAKE FOR A MUCH MORE PLEASANT DAY THAN YESTERDAY.

MODELS REMAIN CONSISTENT IN BRINGING A WEAK LOW TOWARD SWRN PA BY
MIDDAY FRIDAY...BEFORE A STRONGER SECONDARY FORMS ON THE MID
ATLANTIC COAST AND MOVES OUT OVER THE OCEAN FRIDAY NIGHT AND
SATURDAY. WHILE THE SURFACE LOW WILL BE UNIMPRESSIVE...THE
ASSOCIATED LARGE SCALE FORCING WILL BE RATHER VIGOROUS. THE
COUPLED UPPER JET IS USED TO GENERATE A PERIOD OF STRONG
FRONTOGENESIS WARM ADVECTION/WHICH WILL RESULT IN AN 8-12 HOUR
PERIOD OF MODERATE TO HEAVY PRECIPITATION FOR THE REGION.

LATEST SREF/GEFS AGREE IN BRINGING THE PRECIP/SNOW INTO MY SWRN
ZONES BY MIDNIGHT...AND OVERSPREADING MOST OF THE REMAINDER OF MY
FCST AREA BY DAWN.

QUESTIONS THAT WILL NEED ADDRESSING IN THE NEAR TERM IS HOW MUCH
SNOW WILL FALL ALONG THE MD BORDER AND IF THE CURRENT WATCH SHOULD
BE UPGRADED TO A WARNING FOR BEDFORD-FULTON. LATEST GRIDS DO NOT
HAVE ANY MIXED PRECIP OVER THE FAR SOUTH EXCEPT FOR THE LAURELS.
WILL WAIT FOR THE LATEST GUIDANCE TO MAKE ADJUSTMENTS IF NEEDED.

FROM EARLIER...

IN TERMS OF PCPN/SNFL...USED A MULTI-MODEL BLEND
WITH PSEUDO BIAS CORRECTION FOR QPF AND DERIVED SNFL AMTS FROM
MEAN 10:1 SLR AND WPC WWD INTERNAL GUIDANCE. THIS OUTPUT LINED UP
VERY WELL WITH THE SREF AND GEFS MEANS IN EACH 6 HR PERIOD ENDING
06 AND 12Z FRIDAY WITH THE HIGHEST AMTS /2-3 INCHES/ OVER THE
SOUTH- CENTRAL COUNTIES JUST NORTH OF THE MD/WV PNHNDLE. WETBULB
EFFECTS WILL CERTAINLY BE IN PLAY AS PCPN SPREADS NWD ACROSS THE
CWA INTO A RELATIVELY DRY AIRMASS ASSOCIATED WITH THE RETREATING
SFC HIGH. WARM ROAD SURFACE TEMPS MAY BE A LIMITING FACTOR FOR
ACCUMULATIONS...HOWEVER SNOW SHOULD START BEFORE DAYBREAK IN THE
SOUTHERN 1/3 TO 1/2 OF THE AREA AND MAY BE HEAVY AT TIMES WITH
LCL-BRIEF 1"/HR RATES POSSIBLE. AS WE GET LATER IN THE
MORNING/AFTN HOURS...THE STRONG LATE MARCH SUN ANGLE/INSOLATION
COMBINED WITH MARGINAL SFC TEMPS MAY OFFSET SNFL ACCUM ON ROADS.
THE HIGHEST TERRAIN IS USUALLY THE BIG WINNER IN LATE SEASON SNOW
EVENTS.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
HAVE INCREASED POPS TO ARND 100 PCT ACROSS ALL OF CENTRAL PA
FRIDAY...WHEN ALL MDL GUIDANCE TRACKS FAST-MOVING SHORTWAVE THRU
THE AREA. ALTHOUGH ASSOC MILLER-B SFC LOW REMAINS WEAK AS IT
TRACKS UP THE OHIO VALLEY...COMBINATION OF SFC LOW AND HIGH OFF
THE NEW ENG COAST SHOULD CREATE ENOUGH SOUTHERLY FLOW/OVERRUNNING
FOR A LIGHT TO MOD PRECIP EVENT. 00Z GEFS OUTPUT SHOWS A PERIOD OF
ANOMALOUS LOW LVL SOUTHERLY FLOW/PWATS AS LL JET PASSES OVR THE
REGION FRIDAY. COUPLED JET STRUCTURE ALOFT WILL AID LG SCALE
ASCENT. EASTWARD PROPAGATION OF JET STREAK IN THE OHIO VALLEY WILL
COMBINE WITH ENTRANCE REGION OF WEAKER JET OVR NEW ENG...RESULTING
A MERGER OF ASCENDING BRANCHES OF DIRECT/INDIRECT JET CIRCULATIONS
ACROSS PA.

MDL SOUNDINGS...AS WELL AS GEFS/SREF PTYPE PROBS...INDICATE THE
BULK OF PRECIP SHOULD FALL AS SNOW. HOWEVER...SURGE OF WARMER AIR
WEST OF THE ALLEGHENIES COULD RESULT IN SOME RAIN OVR PORTIONS OF
THE LAUREL HIGHLANDS. AN EXAMINATION OF OMEGA/THERMAL TIME
SECTIONS IMPLIES PLENTY OF RIMING IN THE LOWER CLOUD LAYER WITH
TEMPS ARND -5C...SO SNOW RATIOS ARE NOT LIKELY TO EXCEED ARND
10/1. IN ADDITION...HIGH SUN ANGLE SHOULD RESULT IN DAYTIME ACCUMS
CONFINED MAINLY TO NON-PAVEMENT SURFACES. BIGGEST IMPACT IN THE
FORM OF SNOW-COVERED ROADS SHOULD COME DURING THE AM COMMUTE...BEFORE
WARMING EFFECT OF HIGH SUN ANGLE.

CONSALL QPF AND ASSUMPTION OF SNOW/WATER RATIOS NOT FAR FROM 10/1
TRANSLATE TO LIKELY SNOW TOTALS OF 4-6 INCHES ACROSS A LARGE
PORTION OF CENTRAL PA. THE HIGHER TERRAIN SOUTH OF JOHNSTOWN/ALTOONA
MAY SEE ACCUMS OF 6-8 INCHES...BASED ON SLIGHTLY HIGHER ENS MEAN
QPF AND SLIGHTLY LOWER BLYR TEMPS DUE TO ELEVATION. SLIGHTLY LOWER
AMTS EXPECTED ACROSS THE N TIER COUNTIES...FURTHER FROM SFC LOW. A
WINTER WX ADVY HAS BEEN ISSUED FOR MUCH OF THE AREA WITH FCST
ACCUMS IN THE 2-4/3-6" RANGE. A WINTER STORM WATCH WAS ISSUED FOR
BEDFORD AND FULTON COS WHERE THERE IS POTENTIAL FOR ACCUMS IN
EXCESS OF 6 INCHES.

GIVEN THE TIME OF YEAR AND MARGINAL SFC TEMPS...MUCH OF THE ACCUM
WILL LIKELY BE ON NON-PAVEMENT SURFACES. IN ADDITION...AS IS
TYPICAL THIS TIME OF YEAR...DAYTIME SNOW ACCUMS WILL LIKELY BE
ELEVATION DEPENDENT DUE TO MARGINAL BLYR TEMPS...WITH THE HIGHEST
AMTS ON THE RIDGETOPS.

DIMINISHING SNOW MAY LINGER INTO EARLY FRI EVENING ACROSS EASTERN
PA...AS WEAK PRIMARY LOW FIZZLES WEST OF THE APPALACHIANS AND
SECONDARY LOW SHIFTS OFF THE MID ATLANTIC COAST.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A FAIR AMT OF AGREEMENT THRU NEXT WEEKEND AMONG MED RANGE
GUIDANCE...ALL OF WHICH SHOW A PIECE OF THE POLAR VORTEX HEADING
SE FROM HUDSON BAY INTO SOUTHERN QUEBEC...PUSHING A SHARP COLD
FRONT THRU PA ON SATURDAY. TEMPS SHOULD REACH NEAR OR ABOVE SEASONAL
NORMS AHEAD OF FRONT SAT. HOWEVER...COLD AND DRY WX ON TAP FOR
SUNDAY INTO EARLY NEXT WEEK...AS ARCTIC HIGH BUILDS SOUTH INTO THE
REGION. 00Z GEFS PLUMES AND ECENS DATA IMPLY MONDAY WILL BE THE
COLDEST DAY WITH HIGHS STRUGGLING TO HIT 30F OVR THE N MTNS AND
AM LOWS POTENTIALLY IN THE SINGLE DIGITS ACROSS THE ALLEGHENY
PLATEAU. MODERATING TEMPS AND THE CHC OF RAIN SHOWERS APPEAR LKLY
ARND THE MIDDLE OF NEXT WEEK...AS SFC LOW TRACKS WEST OF PA AND
TRAILING COLD FRONT ARRIVES.

&&

.AVIATION /14Z THURSDAY THROUGH MONDAY/...

HIGH PRESSURE OVER CENTRAL PA AIRSPACE WILL PROVIDE WIDESPREAD
VFR TODAY. SFC WINDS 330-360 AOB 5KTS THROUGH THE AFTN WILL SHIFT
TO 090-150 FROM THIS EVENING INTO TONIGHT. WEAK LOW PRESSURE
TRACKING INTO THE SRN MID-ATLC REGION WILL RESULT IN WIDESPREAD
MVFR TO IFR SNOW SPREADING SW TO NE FROM APPROX 06-15Z FRI.

A SEVERAL HOUR PERIOD OF IFR CONDS IN -SN IS LKLY THRU LATE
MORNING WITH HIGHEST CONFIDENCE OVER THE SRN AIRFIELDS. A
RAIN/SNOW MIX IS STILL POSSIBLE DURING THE AFTN OVER THE SE
AIRFIELDS...BUT OVERALL THERMAL PROFILES SUPPORT THE BULK OF THE
PCPN AS SNOW. SNOW ENDS FROM W TO EAST BY LATE FRI EVENING WITH
LOW CIGS LKLY HOLDING INTO FRIDAY NIGHT ESPECIALLY OVER THE WRN
TAFS IN ZOB SECTOR. SOME LINGERING DZ/FZDZ IS ALSO POSSIBLE INTO
SATURDAY MORNING.

OUTLOOK...
