AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
838 PM EST MON FEB 18 2013

.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA EARLY ON TUESDAY...BRINGING A
WINTRY MIX TO THE AREA. BEHIND THE FRONT...SNOW SHOWERS CAN BE
EXPECTED ACROSS THE AREA AS AN ARCTIC AIR MASS SETTLES INTO THE
REGION TUESDAY NIGHT INTO WEDNESDAY. HIGH PRESSURE WILL RETURN DRY
WEATHER ON THURSDAY BEFORE THE NEXT FRONTAL SYSTEM BRINGS A WINTRY
MIX TO THE AREA ON FRIDAY.

&&

.NEAR TERM /THROUGH TUESDAY/...
...MESSY NIGHT ON TAP FOR AREAS FROM PITTSBURGH NORTHWARD...

THIS IS NOT A FORECAST THIS METEOROLOGIST WOULD LIKE TO DO AGAIN.
MODEL SOLUTIONS FLY DIRECTLY IN THE FACE OF FORECASTER
INTUITION...HOWEVER THE SOLUTIONS ARE BOTH CONSISTENT ON A MODEL-
TO-MODEL AND RUN-TO-RUN BASIS. THIS MAKES THROWING THEM OUT A
PERILOUS ENDEAVOR AT BEST. AS SUCH...THE FORECAST HAS BEEN
ADJUSTED COLDER ACROSS ALL AREAS FROM PITTSBURGH TO THE NORTH AND
EAST OVERNIGHT INTO TUESDAY...WHICH RESULTS IN MUCH MORE
INTERESTING WINTER WEATHER CONDITIONS FOR THESE AREAS. BY NO MEANS
IS THIS A CONFIDENT FORECAST...HOWEVER THE CHANGES ARE FAIRLY
ABRUPT...SO I SHALL ATTEMPT TO DO MY BEST TO EXPLAIN THEM.

VERY DRY AIR REMAINS OVER THE REGION THIS EVENING AS DEWPOINTS
ONLY WITHIN THE LAST COUPLE OF HOURS HAVE EVEN STARTED TO CREEP
INTO THE TEENS OF WESTERN PENNSYLVANIA...WHILE LOW TO MID 20S ARE
STILL COMMON OVER OHIO. THE MODELS ARE CURRENTLY UNDERPLAYING THE
LOW LEVEL DRY AIR IN PLACE...WHICH HAS IMPORTANT RAMIFICATION TO
OUR WET BULB PROFILE OVERNIGHT. EVEN STILL...SOUTHWESTERLY FLOW
ALOFT REALLY STARTS TO BRING DEEPER MOISTURE INTO THE AREA AS THE
LEFT EXIT REGION OF AN UPPER JET STREAK HAS ITS EYE DIRECTLY ON
OUR AREA. AS SUCH...STRONG UPPER LEVEL DIVERGENCE LOOKS TO COME
OVER THE AREA CENTERED AROUND 12Z. ADDITIONALLY...AS THE UPPER JET
UNDERCUTS THE UPPER LOW COVER THE WESTERN GREAT LAKES BY THAT
TIME...THE SURFACE FRONTAL SYSTEM LOOKS TO OCCLUDE...LIKELY
SHUNTING OFF THE NORTHWARD SURGE OF WARM AIR INTO THE REGION BY
ROUGHLY 12Z. AS SUCH...CONCURRENT WITH WET BULB EFFECTS BRINGING
THE ENTIRE COLUMN FROM ABOUT 800 MB DOWNWARD ISOTHERMALLY ALONG
THE 0C ISOTHERM FROM PITTSBURGH NORTHWARD...WARM ADVECTION LOOKS
TO BECOME INCREASINGLY INEFFECTIVE AT CHANGING THE THERMAL
CHARACTERISTICS OF THE COLUMN IN PLACE. AS SUCH...BOTH THE NAM AND
GFS FAVOR A DEEP ISOTHERMAL LAYER WITHIN 1C OF FREEZING BELOW 800
MB FOR A HUGE CHUNK OF THE FORECAST AREA DUE TO THE IMPENDING
DEATH OF THE WARM SECTOR OVER THE CWA AS THE UPPER LEVEL DYNAMICS
LARGELY CUT IT OFF AND MID-LEVEL COLD ADVECTION KICKS IN TUESDAY
MORNING. WITH THIS IN MIND...WE QUICKLY CHANGE FROM A STABLE
PRECIPITATION REGIME TO A MORE CONVECTIVE MODE DURING THE MORNING
HOURS...LIKELY CONCURRENT WITH OR JUST SUBSEQUENT TO THE MOST
SIGNIFICANT QPF TO FALL ACROSS THE AREA.

THERE ARE MANY CONFLICTING FACTORS WORKING IN THE FORECAST
TONIGHT...FIRST OF ALL...SURFACE TEMPERATURES ARE CURRENTLY
RUNNING IN THE 35-40F RANGE OVER WESTERN PENNSYLVANIA. SECOND...WE
HAD ABUNDANT SUNSHINE ACROSS THE AREA TO WARM THE GROUND TODAY AND
MELT MOST OF THE PREVIOUS SNOW PACK. THIRD...WHILE DEWPOINTS ARE
VERY LOW...THEY WILL SURELY COME UP. HOWEVER...THE FACT THAT THE
MODELS ARE UNDERPLAYING THE DRY AIR IN PLACE AT INITIALIZATION
MAKES A FORECAST LEANING TOWARD MORE SNOW TO BE A BIT OF A MORE
CONFIDENT PLAY. BECAUSE OF THE COLDER EXPECTATIONS FOR THERMAL
PROFILES...THE FORECAST WAS ADJUSTED TO ALLOW FOR 0.3-0.4 INCHES
OF LIQUID EQUIVALENT ACROSS MOST OF THE AREA. HOWEVER...DUE TO
MELTING IN THE BOUNDARY LAYER AND ON THE GROUND...SIGNIFICANT
ACCUMULATIONS IN PITTSBURGH SEEM UNLIKELY...WITH PROBABLY ONLY THE
NORTHERN REACHES OF THE METRO AREA SEEING MUCH ACCUMULATION AT
ALL. FARTHER NORTH...COLDER TEMPERATURES AT ONSET COMBINED WITH
MORE EFFECTIVE WET BULBING WILL LIKELY MANAGE ROUGHLY 7-9:1
RATIOS...WHICH WOULD FAVOR 2 TO 3 INCH ACCUMULATIONS THERE. IN THE
RIDGES...THE SCENARIO WOULD LIKELY BE ROUGHLY SIMILAR TO THE AREAS
NORTH OF PITTSBURGH.

ONE OTHER FEATURE OF NOTE IS ICING POTENTIAL. NOTHING FROM EITHER
THE NAM OR GFS WOULD FAVOR WIDESPREAD FREEZING RAIN ANYWHERE IN
THE FORECAST AREA TONIGHT. WHAT REMAINS OF THE WARM TONGUE AS THE
SYSTEM OCCLUDES LOOKS TO QUICKLY BE OVERCOME BY WET BULB EFFECTS
SUCH THAT BUFKIT PROFILES ONLY SUGGEST ANY ICING WOULD BE POSSIBLE
IN JEFFERSON COUNTY PENNSYLVANIA. HOWEVER...EVEN HERE...THE LACK
OF SATURATION AS THE PRECIPITATION TYPE ALGORITHM GENERATES
FREEZING RAIN MEANS ANY SUCH DEVELOPMENT WOULD BE EXTREMELY BRIEF.
AS SUCH...FREEZING RAIN WAS NOT CARRIED IN THE FORECAST FOR THE
OVERNIGHT.

HEADLINES WERE LEFT AS THEY WERE BECAUSE OF LOW CONFIDENCE IN
EXPANDING FOR ACCUMULATING SNOW. EVEN IN THE RIDGES...CONFIDENCE IN
ACHIEVING SNOW ACCUMULATION REQUIRING AN ADVISORY WAS
LOW...HOWEVER IT WAS NOT LOW ENOUGH TO WARRANT ALTERING THE
CURRENT HEADLINES. FRIES

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
THE UPPER LOW WILL PUSH INTO THE NORTHEAST TUESDAY NIGHT INTO
WEDNESDAY WITH A BROAD CYCLONIC FLOW ACROSS THE UPPER OHIO VALLEY
THROUGH THIS PERIOD. BEHIND THE COLD FRONT...THE LOW-LEVEL FLOW
WILL VEER FROM SOUTHWESTERLY TO WESTERLY AT 06Z AND CLOSER TO
WEST-NORTHWESTERLY BY 12Z WED. WITH A PARTIALLY FROZEN LAKE
ERIE...THIS SCENARIO FAVORS MOVE OF A WEAK UPSLOPING EVENT FOR THE
RIDGES WITH BOTH LAKE MICHIGAN AND HURON AS POTENTIAL MOISTURE
SOURCES WITH A VORT ENERGY PROVIDING FORCING TUESDAY NIGHT.
THUS...BELIEVE AN ADDITIONAL 1 TO 3 INCHES WILL BE POSSIBLE
TUESDAY NIGHT INTO WEDNESDAY. FOR THE LOWLANDS...SCATTERED SNOW
SHOWERS WILL LEAD TO A GENERAL INCH ACROSS THE AREA THROUGH THIS
PERIOD.

WEDNESDAY NIGHT THROUGH THURSDAY...THE UPPER LOW WILL PUSH WELL EAST
OF THE AREA WITH WEAK RIDGING AND A SURFACE HIGH RETURNING TO THE
AREA. THIS WILL BRING AN END TO ANY LINGERING LAKE EFFECT/UPSLOPING
SNOW SHOWERS ON WEDNESDAY NIGHT WITH A DRY FORECAST ON THURSDAY.

TEMPS WILL BE AROUND 15 DEGREES BELOW NORMAL IN THE WAKE OF THE
FRONT TUES NIGHT THRU WED NIGHT. TEMPS WILL BEGIN TO MODERATE ON
THURSDAY WITH HIGHS 5 TO 10 DEGREES BELOWN NORMAL AS THE CORE OF
COLDEST AIR ADVECTS EAST OF THE AREA.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A DEEP TROUGH ACROSS THE WESTERN CONUS WILL CLOSE OFF INTO A LOW
ACROSS THE NORTHERN PLAINS THURSDAY NIGHT WITH AN OCCLUDING/OCCLUDED
FRONTAL BOUNDARY APPROACHING THE UPPER OHIO VALLEY. THIS FRONT WILL
CROSS THE REGION LATER THURSDAY NIGHT AND FRIDAY. LIKELY POPS AS
THIS SYSTEM PASSES WITH SNOW TO A WINTRY MIX THEN RAIN AS THE FRONT
PROGRESSES EASTWARD. REGION WILL THEN BE IN WEAK COLD ADVECTION
FRIDAY NIGHT INTO SATURDAY. SCATTERED RAIN AND SNOW SHOWERS POSSIBLE
INTO LATE SATURDAY. A GREAT DEAL OF UNCERTAINTY FOR THE WEEKEND AS
MODELS HAVE TIMING AND STRENGTH DIFFERENCES WITH A POSSIBLE COASTAL
LOW DEVELOPING SATURDAY. HIGH PRESSURE WILL THEN RETURN FOR DRY AND
SEASONABLE CONDITIONS FOR SUNDAY. LEFT MONDAY DRY FOR NOW BUT THE
NEXT FAST MOVING STORM SYSTEM WILL BE APPROACHING THE LOWER OHIO
VALLEY AND THIS FORECAST WILL LIKELY CHANGE GREATLY WITH TIME.

&&

.AVIATION /02Z TUESDAY THROUGH SATURDAY/...
VFR CONDITIONS WILL PERSIST FOR THE FIRST HALF OF THE NIGHT BEFORE
A FRONTAL BOUNDARY APPROACHES THE REGION. LOW LEVEL WIND SHEAR
INCLUDED AT ALL TERMINALS LATER THIS EVENING INTO TOMORROW AS LOW
LEVEL JET SURGES FROM THE SOUTHWEST.

PRECIPITATION WILL START OFF AS A RAIN SNOW MIX AT TERMINALS ALONG
PIT AND NORTH AND EVENTUALLY CHANGE OVER TO SNOW ONCE COLDER AIR
USHERS IN WITH COLD FRONT.

IFR CEILINGS WILL OCCUR WITH SNOW AND BEHIND THE FRONTAL PASSAGE
WITH WINDS TURNING SOUTHWEST AND GUSTING TO OVER 20KT LATER
AFTERNOON TUESDAY.

.OUTLOOK.../TUESDAY THROUGH SATURDAY/...
LINGERING RESTRICTIONS ARE ANTICIPATED THROUGH WEDNESDAY IN COLD
NORTHWEST FLOW BEHIND THE FRONT. VFR UNDER HIGH PRESSURE THURSDAY.
POSSIBLE RESTRICTIONS FRIDAY AND SATURDAY IN AN UNSETTLED WEATHER
PATTERN.
