THE STRONG NW WNDS SHUD BE EFFECTIVE IN SCOURING OUT CLDS E OF
BLURDG...BUT ITS UPSLOPE COMPONENT SHUD KEEP MSTR IN PLACE. TOO MUCH
SHEAR FOR SIG SHSN...BUT ENUF FOR AN INCH ACCUM IN FVRD LOCATIONS.
TEMPS TDA CUD BE TRICKY. CNTRL VA HAS BEEN WARM PAST CPL AFTNS...AND
W/ WAA...SEE NO REASON WHY TDA WONT BE A THIRD. ELSW...CLDS SHUD
INHIBIT WARMING. MAV TEMPS FVRD TDA...BLEND SEEMED OK TNGT.

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
FRIDAY...LOW PRESSURE MOVES FURTHER OUT TO SEA AS HIGH PRESSURE
BUILDS OVER THE GREAT LAKES. MODEL FORECAST MSLP CONTINUES TO
INDICATE A TIGHT PRESSURE GRADIENT...AND NEARLY PERPENDICULAR MSLP
AND H10-H5 THICKNESSES CONTOURS DISPLAY TEMPERATURE ADVECTION
SOLENOIDS INDICATIVE OF COLD ADVECTION. GFS AND NAM TEMPERATURE
ADVECTION TIME HEIGHTS AT VARIOUS POINTS VALIDATE THIS...AND
THEREFORE EXPECT ADVECTION TO AID IN VERTICAL MIXING THROUGH SUNSET.
850 MB WINDS FROM THE NAM AND GFS ARE GENERALLY STRONGEST IN THE
MORNING...ON THE ORDER OF 50 TO 60 KT. SO...THE HIGHEST GUSTS WILL
MORE THAN LIKELY OCCUR IN THE MORNING...WITH LOWER MAGNITUDES IN THE
AFTERNOON. FEEL REASONABLY CONFIDENT OF HEADLINE WORTHY GUSTS
CONTINUING FRIDAY MORNING WEST OF THE BLUE RIDGE...AND WILL CONTINUE
PRE-EXISTING WARNING/ADVISORY HEADLINES UNTIL 10 AM WEST OF THE
MTNS. GIVEN ADVECTION AND 850 MB TEMPERATURES GENERALLY FALLING TO
-10 C...HAVE LEANED TOWARD THE LOWER SET OF MOS NUMBERS WHICH FAVORS
TEMPERATURES ABOUT 10 DEGREES F LOWER THAN TODAYS FORECAST HIGHS.
21Z SREF 3 HOUR PRECIP SHUTS OFF ANY UPSLOPE QPF BY 18Z...SO ANY
LINGERING UPSLOPE SNOW SHOWERS WILL END FRIDAY MORNING. WITH THE
UPPER LEVELS BECOMING MORE CONVERGENT AND THE ATMOSPHERE MORE
SUBSIDENT...A SUNSHINE FILLED SKY WILL PREVAIL ON FRIDAY.
FRIDAY NIGHT THROUGH SATURDAY...SHORTWAVE RIDGE AT 500 MB MOVES FROM
THE OHIO VALLEY EAST TO THE MID ATLANTIC. MEANWHILE...HIGH PRESSURE
EXPANDS SOUTHEAST INTO THE MID ATLANTIC BY SATURDAY. GFS SHOWS HIGH
PRESSURE BECOMING DIRTY BY SATURDAY AS AN INFLUX OF H5-H3 MOISTURE
RETURNS ACROSS THE REGION. MOISTURE RETURN MAY BE A LITTLE TOO FAST
DESPITE DEVELOPING WARM ADVECTION ALOFT...AND WILL CONTINUE TO
HIGHLIGHT MOSTLY CLEAR/MOSTLY SUNNY CONDITIONS FOR NOW.
SATURDAY NIGHT THROUGH SUNDAY NIGHT...HIGH PRESSURE MOVES OFF THE
MID ATLANTIC COAST SATURDAY NIGHT...ALLOWING A WEAK RETURN FLOW TO
FORM. FOCUS THEN SHIFTS TOWARD NEARLY VERTICALLY STACKED LOW
PRESSURE IN THE CENTRAL PLAINS. WARM ADVECTION AND ISENTROPIC LIFT
WILL STRENGTHEN AHEAD OF LOW PRESSURE...AND WILL SUPPORT THE
DEVELOPMENT OF PRECIPITATION OVER THE MID ATLANTIC SATURDAY NIGHT.
00Z OPERATIONAL GFS GUIDANCE INDICATES THIS OCCURRING WEST OF THE
MTNS IN THE EVENING...THEN OVERNIGHT EAST OF THE MTNS. THERE/S SOME
SUPPORT FROM THE 21Z SREF REGARDING THIS FASTER FORMATION OF
PRECIPITATION. MORE INTRIGUINGLY IS THE TYPE OF PRECIPITATION THAT
WOULD OCCUR IF PRECIPITATION FORMS THIS EARLY. 21Z SREF CZYS
ALGORITHM INDICATES MAINLY SNOW 78-84 HOURS WHILE THE BALDWIN
ALGORITHM SHOWS SNOW...SLEET AND FREEZING RAIN DURING THE SAME TIME.
00Z GFS BUFKIT SIDES TOWARD THE BALDWIN ALGORITHM...WITH A WINTRY
MIX OF PRECIPITATION BEFORE A PROBABLE CHANGE OVER TO RAIN ON SUNDAY
(EXCEPT PERHAPS OUR NORTH AND WEST CWA WHICH COULD STAY MIXED). NO
MATTER HOW YOU SLICE IT...MODEL GUIDANCE HAS TRENDED COLDER...AND
FASTER WITH THE DEVELOPMENT OF PRECIPITATION...SO THERE IS INCREASED
CONCERN ABOUT WINTRY PRECIPITATION SATURDAY NIGHT INTO EARLY SUNDAY.
LIKE THE CONCEPTUAL DEPICTION OF THE BALDWIN ALGORITHM AND
OPERATIONAL GFS WITH SNOW...SLEET AND FREEZING RAIN GIVEN SURFACE
TEMPERATURES BELOW 32 DEGREES F AND A WARM LAYER A FEW THOUSAND FEET
ABOVE THE GROUND ABOVE 32 DEGREES F. WILL INTRODUCE MENTION OF
WINTRY PRECIPITATION IN THE HWO PRODUCT. BOUNDARY LAYER TEMPERATURES
SHOULD FAVOR LIQUID FOR THE REST OF SUNDAY...AS INITIAL LOW PRESSURE
MOVES INTO THE GREAT LAKES AND NEW LOW PRESSURE FORMS OFF THE MID
ATLANTIC COAST. GIVEN CURRENT TIMING...PRECIPITATION WILL END SUNDAY
NIGHT...AND WOULD PRIMARILY END AS RAIN.
MONDAY THROUGH TUESDAY...UPSLOPE SNOW SHOWERS WILL OCCUR EARLY IN
THE WEEK IN FAVORED LOCATIONS...OTHERWISE HIGH PRESSURE GRADUALLY
BUILDING ACROSS THE AREA WILL BRING A RETURN TO DRY CONDITIONS WITH
TEMPERATURES AT OR SLIGHTLY BELOW CLIMO.
