AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
138 AM EDT WED MAY 13 2015

.SYNOPSIS...
LOW PRESSURE WILL DRIFT ACROSS THE CANADIAN MARITIMES WHILE A
TRAILING AREA OF WRAP AROUND MOISTURE WILL CROSS OUR REGION THIS
MORNING. HIGH PRESSURE WILL BUILD ACROSS OUR REGION TONIGHT WITH
CLEARING SKIES. THIS WILL SET THE STAGE FOR A FROST OR FREEZE AWAY
FROM THE LAKESHORES. PROGRESSIVELY WARMER WEATHER WILL THEN RETURN
DURING THE REST OF THE WEEK AS HIGH PRESSURE WILL PUSH OFF THE
ATLANTIC COASTLINE.

&&

.NEAR TERM /THROUGH TODAY/...
A WEALTH OF LOW LEVEL MOISTURE ACCOMPANIED BY THE PASSAGE OF A MID
LEVEL TROUGH AXIS WILL KEEP CLOUDS IN PLACE THIS MORNING WITH A
CHANCE OF SHOWERS FOCUSED MAINLY EAST OF LAKE ONTARIO BETWEEN
WATERTOWN AND OSWEGO. CONTINUED STEADY COLD AIR ADVECTION WITH
LINGERING WIND GUSTS WILL PUSH TEMPS FURTHER DOWN EARLY THIS
MORNING WITH READINGS BOTTOMING OUT IN THE LOW TO MID 40S BY
DAYBREAK.

LATER TODAY...HIGH PRESSURE AND DRIER AIR CENTERED OVER THE UPPER
GREAT LAKES WILL GRADUALLY BUILD INTO THE REGION. THIS WILL FIRST
BRING AN END TO ANY LEFTOVER SCATTERED LIGHT SHOWERS DURING THE
MORNING HOURS...BEFORE FORCING LINGERING LOW CLOUDS TO LIFT AND
EVENTUALLY SCATTER OUT FROM NORTH TO SOUTH BETWEEN THE LATE MORNING
AND AFTERNOON HOURS. DESPITE THE RESULTANT INCREASE IN AFTERNOON
SUNSHINE...850 MB TEMPS AVERAGING AROUND -1C WILL STILL TRANSLATE TO
A DAY OF MUCH COOLER TEMPERATURES...WITH HIGHS ONLY RANGING FROM THE
LOWER 50S ACROSS THE SOUTHERN TIER /WHERE CLOUDS WILL LINGER THE
LONGEST/ TO THE MID AND UPPER 50S ELSEWHERE...OR READINGS THAT WILL
BE A SOLID 5 TO 10 DEGREES F BELOW MID-MAY NORMALS.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
WEDNESDAY NIGHT HIGH PRESSURE WILL SETTLE DIRECTLY OVERHEAD. ANY
LEFTOVER DIURNAL CUMULUS OR STRATOCUMULUS WILL QUICKLY CLEAR
DURING THE EVENING. THIS WILL LEAVE CLEAR SKIES AND LIGHT WINDS IN
A COOL/DRY AIRMASS...WHICH WILL RESULT IN NEAR IDEAL RADIATIONAL
COOLING CONDITIONS BY MID MAY STANDARDS. EXPECT LOWS TO DROP INTO
THE MID TO UPPER 30S IN MOST AREAS AWAY FROM THE IMMEDIATE
LAKESHORES...WITH SOME OF THE NORMALLY COLDER SOUTHERN TIER
VALLEYS AND TUG HILL REGION POSSIBLY DROPPING INTO THE UPPER 20S
TO AROUND 30. THIS WILL BRING THE POTENTIAL FOR AT LEAST PATCHY
FROST TO MUCH OF THE AREA...WITH MORE WIDESPREAD FROST ACROSS THE
COLDER INTERIOR SOUTHERN TIER AND NORTH COUNTRY.

GIVEN THE FORECAST TEMPS...WE HAVE GONE WITH A FREEZE WATCH FOR
CATTARAUGUS...ALLEGANY...AND LEWIS COUNTIES WHERE THE COLDEST
TEMPERATURES ARE EXPECTED. IF CURRENT TRENDS CONTINUE...FROST
ADVISORIES MAY BE NEEDED FOR AT LEAST ONE MORE TIER OF COUNTIES
AROUND THE WATCH...AND POSSIBLY FOR MOST OF THE AREA.

HIGH PRESSURE WILL REMAIN OVERHEAD ON THURSDAY WITH ABUNDANT
SUNSHINE. AFTER A CHILLY START...TEMPERATURES WILL RECOVER INTO
THE MID 60S AT LOWER ELEVATIONS AND AROUND 60 ACROSS THE HIGHER
TERRAIN. STRONG DIFFERENTIAL HEATING AND LIGHT BACKGROUND SYNOPTIC
SCALE FLOW WILL ALLOW LAKE BREEZES TO FORM BY EARLY
AFTERNOON...KEEPING THE LAKESHORES COOLER. HIGH PRESSURE WILL
BEGIN TO DRIFT EAST INTO NEW ENGLAND AND THE MID ATLANTIC THURSDAY
NIGHT. THE AIRMASS WILL HAVE MODERATED SOME...SO LOWS WILL NOT BE
QUITE AS COLD AS THE PREVIOUS NIGHT. EXPECT MID 40S ON THE LAKE
PLAINS OF WESTERN NY WITH UPPER 30S TO AROUND 40 IN THE COOLEST
SOUTHERN TIER VALLEYS AND EAST OF LAKE ONTARIO. THE COLDER REGIONS
OF LEWIS COUNTY MAY AGAIN DROP COLD ENOUGH FOR FROST...BUT
OTHERWISE THE REST OF THE AREA WILL BE TOO MILD.

ON FRIDAY HIGH PRESSURE WILL DRIFT OFF THE EAST COAST AND ALLOW A
MILDER AIRMASS TO BEGIN TO MOVE BACK INTO THE REGION. A MID LEVEL
SHORTWAVE WILL MOVE QUICKLY EAST ACROSS THE GREAT LAKES DURING THE
AFTERNOON AS A WELL DEFINED WARM FRONT DEVELOPS NORTHEASTWARD OUT
OF THE OHIO VALLEY. THE COMBINATION OF INCREASING LARGE SCALE
ASCENT FROM THE MID LEVEL SHORTWAVE AND CONVERGENCE/ISENTROPIC
LIFT ALONG THE WARM FRONT WILL BRING INCREASING RAIN CHANCES FROM
WEST TO EAST LATER IN THE DAY...LASTING THROUGH AT LEAST A PORTION
OF FRIDAY NIGHT AS THE WARM FRONT MOVES NORTHEAST ACROSS THE AREA.
MODEL GUIDANCE HAS BEEN FAIRLY CONSISTENT WITH THIS OVER THE PAST
24 HOURS...WITH ENOUGH CONFIDENCE TO INCREASE POPS TO LIKELY.
LATEST GFS CONTINUES TO SHOW LITTLE IF ANY INSTABILITY...SO HAVE
LEFT MENTION OF THUNDER OUT. TEMPERATURES WILL CONTINUE TO WARM
WITH HIGHS IN THE LOWER TO MID 70S IN MOST AREAS ON FRIDAY.
OVERNIGHT LOWS FRIDAY NIGHT WILL BE MUCH MILDER...WITH LOW TO MID
50S IN MOST AREAS UNDER MORE CLOUD COVER.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
TEMPERATURES WILL WARM TO ABOVE AVERAGE ONCE AGAIN THROUGH THE
LONG TERM PERIOD...WITH THE WARMTH PEAKING SUNDAY AND MONDAY WHEN
TEMPERATURES WILL LIKELY RISE INTO THE 80S ONCE AGAIN FOR HIGHS.

ON SATURDAY THE WARM FRONT WILL BECOME MORE ILL-DEFINED AS IT
DRIFTS ACROSS THE AREA AND INTO NEW ENGLAND. THE DEEPER MOISTURE
WILL REMAIN TO OUR SOUTH FROM THE OHIO VALLEY INTO SOUTHERN NEW
ENGLAND...BUT ENOUGH MOISTURE AND ASCENT MAY REMAIN TO SUPPORT A
LOW CHANCE OF A SHOWER OR THUNDERSTORM. THE GREATEST CHANCES WOULD
LIKELY BE ALONG AND INLAND FROM ANY LAKE BREEZE BOUNDARIES THAT
FORM. BY SUNDAY THE DEEPER MOISTURE WILL SETTLE A LITTLE FARTHER
SOUTH AS BUBBLE OF HIGH PRESSURE AND DRIER AIR BUILDS ACROSS
QUEBEC. THIS SHOULD CONFINE ANY RAIN CHANCES TO THE SOUTHERN TIER
AND EXTENDING SOUTH INTO PA...WITH THE REST OF THE AREA REMAINING
DRY.

BY MONDAY A MUCH STRONGER MID LEVEL TROUGH WILL MOVE EAST ACROSS
THE GREAT LAKES WITH A STRONG COLD FRONT CROSSING THE AREA MONDAY
NIGHT IN THE LATEST 12Z GFS AND ECMWF. THIS FRONT WILL BRING A
BETTER CHANCE OF MORE WIDESPREAD SHOWERS AND POSSIBLY A FEW
THUNDERSTORMS.

BY TUESDAY THE COLD FRONT SWEEPS EAST OFF THE EASTERN SEABOARD...
WITH A MUCH COOLER AND DRIER AIRMASS BUILDING INTO THE GREAT LAKES
STATES.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
VFR CONDITIONS IN PLACE EARLY THIS MORNING WITH LINGERING OVC CIGS
AND SCATTERED SHOWERS FOCUSED MAINLY EAST OF LAKE ONTARIO TO THE
SOUTH OF KART. RECENT MVFR CIGS AT KJHW HAVE LIFTED TO VFR.

AFTER DAYBREAK...HIGH PRESSURE AND DRIER AIR CENTERED OVER THE UPPER
GREAT LAKES WILL GRADUALLY BUILD INTO THE REGION. THIS WILL BRING AN
END TO ANY LEFTOVER SCATTERED SHOWERS DURING THE MORNING...AND WILL
ALSO FORCE CIGS TO LIFT TO VFR AND THEN SCATTER OUT FROM NORTH TO
SOUTH BETWEEN THE LATE MORNING AND AFTERNOON HOURS.

OUTLOOK...
TONIGHT THROUGH THURSDAY NIGHT...VFR.
FRIDAY...VFR FRIDAY MORNING...THEN SHOWERS LIKELY WEST OF KROC IN
THE AFTERNOON ALONG WITH POSSIBLE REDUCTIONS TO MVFR.
FRIDAY NIGHT...VFR/MVFR WITH SHOWERS LIKELY.
SATURDAY...MAINLY VFR WITH A CHANCE OF SHOWERS AND THUNDERSTORMS.
SUNDAY...MAINLY VFR WITH A
CHANCE OF SHOWERS SOUTH OF KBUF/KROC.

&&

.MARINE...
A BRISK WESTERLY FLOW OF COOLER AIR WILL CONTINUE TO PRODUCE ADVISORY-LEVEL
WINDS AND WAVES ACROSS THE LOWER GREAT LAKES THROUGH THIS MORNING.
HIGH PRESSURE WILL THEN BUILD ACROSS THE REGION THROUGH
TODAY...ALONG WITH IMPROVING CONDITIONS. TRANQUIL WEATHER CAN THEN
EXPECTED THURSDAY AND MUCH OF FRIDAY AS THE HIGH WILL SLOWLY DRIFT
EASTWARD AND EVENTUALLY OFF THE ATLANTIC COASTLINE. AN APPROACHING
WARM FRONT WILL BRING A RENEWED CHANCE OF CONVECTION BY THE WEEKEND.
