DANGELO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
751 AM EDT FRI APR 27 2012

.SYNOPSIS...
HIGH PRESSURE WILL NOSE INTO THE AREA FROM CENTRAL CANADA TODAY. A
LOW PRESSURE AREA WILL MOVE THROUGH THE MIDWEST TODAY AND TO THE
SOUTH OF THE AREA ON SATURDAY. A FRONTAL BOUNDARY WILL STALL TO
THE SOUTH OF THE AREA. THE FRONT WILL MOST LIKELY BUBBLE BACK TO
THE NORTH AS THE UPPER LEVEL TROUGH OVER THE NORTHEAST WILL LIFT
OUT THIS WEEKEND. THE RESULTING ZONAL FLOW WILL BRING IN WARM AIR
AND MORE MOISTURE...LEADING TO PERIODS OF SHOWERS AND
THUNDERSTORMS.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CLOUDS HANGING TOUGH WITH 8H THERMAL TROUGH STILL TO THE
WEST...AND CYCLONIC FLOW OVERHEAD. THE MIXING OF THE
DAY AND ADVECTION OF DRIER AIR INTO THE REGION WILL ACT TO
DISSIPATE THE STRATUS. THE LOW CLOUDS AND EVEN A SPRINKLE OR
FLURRY WILL HANG ON LONGEST IN THE NERN MTS...AND WILL MENTION
THROUGH MID-MORNING. THE REST OF THE AREA WILL CONTINUE TO CLEAR
WITH JUST A FEW DIURNAL CU POSSIBLE AS THE HIGH PRESSURE NOSES
DOWN FROM THE UPPER GREAT LAKES. THE TEMPS WILL START OUT
CHILLY...WITH NEAR FZG TEMPS IN THE N/W. HOWEVER...DECENT LATE-
APRIL SUNSHINE AND MIXING SHOULD LEAD TO TEMP GAINS OF 10-15F
DESPITE THE COLD ADVECTION.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/...
ANOTHER COLD NIGHT FRIDAY NIGHT AHEAD OF THE NEXT SYSTEM.
RELATIVELY LIGHT WINDS AND CLEAR SKIES EARLY SHOULD ALLOW TEMPS TO
DROP OFF. HAVE COORDINATED A WIDESPREAD FREEZE WATCH...AS MOST OF
THE AREA WILL GO BELOW FREEZING...AND THE OTHER AREAS WILL MOST
LIKELY HAVE A WIDESPREAD FROST WITH TEMPS BOTTOMING OUT IN THE
LOWER TO MID 30S.

SYSTEM MOVING ACROSS THE MIDWEST TODAY WILL SPREAD PRECIPITATION
INTO THE OHIO VALLEY OVERNIGHT. IT HEADS INTO THE MID-ATLANTIC ON
SLIGHT NWRLY FLOW. HOWEVER...GOOD DRY AIR AT THE SFC WILL MOST
LIKELY LIMIT THE NRN EXTENT OF THE PRECIP TO A SHARP W-E LINE.
WHERE THE LINE WILL BE IS AN INTERESTING PROBLEM SINE THE TEMPS
ALOFT WOULD BE CONDUCIVE FOR SNOW IF THE SHIELD OF OVERRUNNING
PRECIP WAS TO GET INTO NRN PA DURING SAT NIGHT. DIFFERENCES
BETWEEN THE NAM AND ALL OTHER MODELS AND MOST OF THE 03Z SREF
MEMBERS GIVES HIGH CONFIDENCE IN A NON-NAM SOLUTION. THE NAM IS
CONSISTENT YET AN OUTLIER WITH A MORE-NORTHERLY EXPANSION OF THE
PRECIP AND A SLOWER FORWARD PROGRESS. THE FLAT FLOW AND LIMITED
MOISTURE OF THE SYSTEM LEAN THE FORECAST TO A FASTER PASSAGE -
MORE DURING THE DAYLIGHT HRS THAN IN THE NIGHT. THIS FASTER
MOVEMENT IS THE APPEARANCE OF THE OTHER OPERATIONAL MODELS
INCLUDING THE ECMWF AND GFS. THERE IS A LOW PROBABILITY OF SOME
SNOW MIXING IN OVER THE NRN MTS...AND CONTINUITY OF PREV FCST WILL
KEEP JUST A MENTION EARLY IN THE NIGHT OVER THE HIGHER ELEVS OF
THE NRN MTS. THIS COLDER SCENARIO LOOKS LESS PROBABLE AS WE GET
CLOSER TO THE EVENT.

AFTER THE WAVE PUSHES TO THE EAST...WHICH SHOULD BE AROUND OR
AFTER MIDNIGHT SAT NIGHT...THE SKIES START TO CLEAR. THIS WILL
LEAD TO ANOTHER COLD NIGHT AND ANOTHER CHANCE FOR A FREEZE. SUNDAY
WILL BE MAINLY CLEAR BUT THE FRONTAL BOUNDARY TO THE SOUTH WIL
REMAIN IN CLOSE PROXIMITY...SO ISOLD SHOWERS MAY NOT BE TOO FAR S
OF THE PA BORDER. MAXES ON SUNDAY SHOULD BOUNCE BACK INTO THE 50S
AND 60S.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
GRADUAL WARMING TREND CONTINUES MONDAY AS HIGHS THROUGH NEXT WEEK
INCREASE ABOUT 5F EACH DAY IN RETURN FLOW ON BACK OF HIGH.
INDIVIDUAL SHORTWAVES...WHICH ARE VERY HARD TO RESOLVE AT THESE
RANGES...WILL MODULATE OPPORTUNITIES OF PCPN. THE NEXT HIGH CHC OF
PRECIP WILL BE DURING A TIME OF MCS-FAVORABLE CONDITIONS MONDAY
NIGHT. WILL GO WITH 30-40 POPS FOR MONDAY NIGHT...THEN PERPETUAL
20-30 POPS BE CARRIED ON THRU THURS.

&&

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
GUSTY NWLY FLOW OVR THE LWR LAKES ON BACKSIDE OF DEEP LOW LIFTING
INTO THE MARITIMES WILL BRING STRATOCU MVFR/VFR CIGS TO WESTERN
AND CENTRAL TAFS THRU THE EARLY MORNING...BEFORE BREAKING UP INTO
THE AFTN. E OF THE MTNS...DOWNSLOPE WILL AID IN MAINTAINING VFR
WITH LESS CLOUDS AND HIGHER CIGS BTWN 5-6KFT AGL.

EXPECT INCREASING NW WINDS THRU THE MID MORNING INTO THE AFTN AS
DEEP BLYR MIXING TAPS STG WINDS ALOFT...RESULTING IN FQNT 25-35KT
SFC WND GUSTS. DOWNSLOPE EFFECT SHOULD ENHANCE/CHANNEL WINDS A
LITTLE MORE OVR ERN SITES AND HAVE INDICATED HIGHER GUSTS AT THESE
SITES. THE WINDS WILL SUBSIDE TONIGHT AS HIGH PRESSURE RIDGE AXIS
SLIDES EWD FROM THE UPPER OH VLY.

OUTLOOK...
SAT...MVFR RESTRICTIONS LKLY. RAIN DEVELOPING.
SUN...MVFR CIGS PSBL SOUTH EARLY. NO SIG WX.
MON...VFR WITH CHC OF SHOWERS.
TUE...MVFR WITH CHC OF SHOWERS.

&&

.FIRE WEATHER...
FIRE WEATHER CONCERNS COULD BE AN ISSUE...ALTHOUGH SURFACE
DEWPOINTS WILL BE MARGINAL FOR RED FLAG CONDITIONS. THE FUELS ARE
DRY DESPITE THE SNOW AND LITTLE BIT OF RAIN ON MONDAY AND MAINLY
LIGHT SHRA THURSDAY. WILL ALLOW THE DAY SHIFT TO COLLABORATE WITH
FIRE MANAGERS ON NEED FOR FIRE WX FLAGS.
