.NEAR TERM /THROUGH WEDNESDAY/...
WEAKENED MCC MVG THRU THE AREA ATTM. TIMING OF THE PASSAGE HAS
REALLY ELIMINATED ANY HTG AND SUBSEQUENT DESTABILIZATION SO THERE
HAS NOT AS YET BEEN ANY REFIRING OF THE CONV. SHRT TERM MODELS
SEEMED TO HAVE GRABBED THIS TREND HAVE NOW REALLY BACKED OFF ON
THE HEAVY QPF OVRNGT. SO...HAVE REMOVED THE WRDG OF HEAVY RAIN
AND MENTION OF FLASH FLOODING FROM THE HWO. STILL...THERE ARE A
FEW BRKS OVER WRN NY SO SOME RENEWED CONV PSBL THRU THE EVE BEFORE
DRIER AND MORE STABLE AIR MVES IN LATE.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
BUBBLE HI AND DRIER AIR ON WED HAD OF THE NEXT LAKES SYSTEM. FCSTD
SNDGS GNRLY SHOW THE MID AND UPR LVL STABLE LIMITING ANY CONV. BY
WED NGT...SHRT WV APCHG LWRS HGTS AND DESTABILIZIS THE SNDGS ENUF
FOR SHWRS AND A FEW TRWS OVRNGT INTO EARLY THU. LINGER UPR TROF

XTNDD PD STARTS OFF DRY WITH SFC HIPRES IN THE WRN END OF A BROAD WRN
ATLANTIC TROF. BY LATE SAT...MODELS SHOW MOISTURE STREAMING IN
FROM THE LAKES COULD START TO TRIGGER SOME CONV SHWRS. CHANCE FOR
PCPN INCRS/S ON SUN AS A WV AND SFC LOW MVES EAST. OF

BE DETERMINED BUT IT LOOKS LIKE A DECENT BET FOR INCRSD CVRG OF
SHWRS AND STORMS SUN INTO MON. LOOKS LIKE SOME DRIER AIR BEGINS TO

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
ANY LINGERING CONVECTIVE ACTIVITY SHOULD BE OUT OF OUR FORECAST
AREA BY AROUND 02Z. BRIEF NEAR-TERM RESTRICTIONS WERE MENTIONED AT
KRME AND KAVP.

THE MAIN ISSUE LATER TONIGHT WILL BE THE POTENTIAL FOR CEILING/VSBY
RESTRICTIONS...AS LOWER CLOUDS/FOG WILL BE IN THE VICINITY...NEAR
SLOW MOVING SURFACE WARM FRONT. WE FEEL THE BEST CHANCE FOR SUCH
DEVELOPMENT WILL BE AT KSYR AND KRME...NEAR AND TO THE NORTHEAST
OF THE AFOREMENTIONED BOUNDARY. EVEN AT THE REMAINING
TERMINALS...ENOUGH RESIDUAL MOISTURE IN PLACE FOR POTENTIAL FOG
FORMATION...EVEN IF LOWER CLOUDS DO NOT MATERIALIZE. AT THIS
JUNCTURE...UNCERTAINTY/LOW CONFIDENCE REGARDING IFR...AND WILL
SIMPLY GO WITH MVFR RESTRICTIONS.

BY MID TO LATE MORNING WED...A SOMEWHAT DRIER WESTERLY FLOW WILL
DEVELOP...WITH WARM FRONT RETREATING TO THE EAST. VFR SHOULD
PREVAIL AREA-WIDE. BY LATE IN THE DAY....ISOLATED TO SCATTERED
CONVECTION COULD RE-FIRE...BUT GIVEN EXPECTED HIT AND MISS
COVERAGE...WILL OPT NOT TO MENTION IN THE TERMINALS AT THIS
DISTANT TIME RANGE.

OUTLOOK...

WED NGT/THUR...ANOTHER ROUND OF MVFR POSSIBLE...IN SHOWERS/TSTMS.
LOCALIZED IFR MAY ALSO OCCUR.

FRI/SAT...VFR. MAYBE SOME MVFR/IFR VALLEY FOG BOTH MORNINGS.
