AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
1200 PM EDT MON JUL 25 2011

.SYNOPSIS...
WEAK LOW PRESSURE OVER GEORGAIN BAY WILL MOVE NORTHEAST TODAY AND
WILL LIFT AN ILL DEFINED FRONTAL BOUNDARY BACK ACROSS OUR REGION
IN THE PROCESS. THIS WILL HELP TO GENERATE SCATTERED SHOWERS
THUNDERSTORMS TODAY...WITH THE RISK OF STRONG TO SEVERE STORMS OVER
THE FINGER LAKES. THE BASE OF AN UPPER LEVEL TROUGH WILL THEN SWING
BY THE REGION ON TUESDAY...POSSIBLY SPARKING A FEW MORE SCATTERED
SHOWERS OR THUNDERSTORMS. HIGH PRESSURE WILL THEN BUILD ACROSS THE
LAKES TO PROVIDE US WITH A SUNNY AND PLEASANT DAY WEDNESDAY WITH LOW
HUMIDITY.

&&

.NEAR TERM /THROUGH TONIGHT/...
...SEVERE THUNDERSTORMS WATCH 683 IN EFFECT UNTIL 23Z FOR MUCH OF
OUR CWA...

THE LATEST SURFACE MAP SHOWS LOW PRESSURE CENTERED OVER WESTERN LAKE
ONTARIO WITH A TRAILING COLD FRONT PUSHING THROUGH LAKE ERIE. VERY
MOIST AND INCREASINGLY UNSTABLE AIR SOUTH AND EAST OF THE FRONT WILL
CONTINUE TO GENERATE SHOWERS AND THUNDERSTORMS. SOME STORMS WILL BE
SEVERE AS THE DEEP LAYERED SHEAR BECOMES EVEN MORE FAVORABLE AS THE
UPPER LEVEL JET STREAK APPROACHES FROM THE CENTRAL GREAT LAKES.
DAMAGING WINDS FROM BOWING ECHOES AND LARGE HAIL ARE THE PRIMARY
SEVERE WEATHER THREATS.

THE LAKE BREEZE DOWNWIND OF LK ERIE WILL HELP TO DESTABILIZE THE
ATMOSPHERE ACROSS MUCH OF THE NIAGARA FRONTIER...WHILE RAIN COOLED
AIR WILL KEEP THE AIR MOST STABLE ACROSS JEFFERSON COUNTY.

THE STORMS WILL ALSO BE ACCOMPANIED BY HEAVY RAIN WHICH IS CERTAINLY
WELCOME AFTER THE PROLONGED DRY WEATHER OF THE PAST COUPLE MONTHS.
BASIN AVERAGE QPF TODAY SHOULD BE IN THE VCNTY OF A QUARTER TO ONE
HALF INCH. HOWEVER...SITES THAT EXPERIENCE STORMS COULD PICK UP OVER
ONE INCH OF RAIN.

TEMPERATURES TODAY WILL CONTINUE TO AVERAGE ABOVE NORMAL FOR MOST
SITES...WITH H85 TEMPS OF 16C SUPPORTING HIGHS OF 80 TO 85. THE
WARMEST CONDITIONS WILL BE FOUND ALONG THE NIAGARA ESCARPMENT AND
ACROSS THE GENESEE VALLEY.

TONIGHT...OUR REGION WILL BE FOUND IN SOMEWHAT OF A LULL BETWEEN TWO
SHORTWAVES. THE FIRST WILL BE EXITING ACROSS THE ST LAWRENCE VALLEY.
WHILE THERE COULD BE SOME LEFTOVER SHRA/TSRA EARLY TONIGHT...
ESPECIALLY EAST OF THE GENESEE VALLEY...THE BULK OF TONIGHT SHOULD
BE RAIN FREE.

THE SECOND SHORTWAVE WILL TAKE AIM ON THE REGION LATE TONIGHT FROM
THE UPPER GREAT LAKES AS IT WILL DROP SOUTHEAST ACROSS GEORGIAN
BAY. SHOWERS AND THUNDERSTORMS FROM THIS FEATURE SHOULD HOLD OFF
UNTIL AFTER DAYBREAK TUESDAY.

TEMPERATURES TONIGHT WILL SETTLE INTO THE LOWER 60S FOR MOST
AREAS...WITH 50S ACROSS THE SRN TIER AND ALSO THE TUG HILL PLATEAU.
THESE TEMPS WILL BE SOME OF THE LOWEST IN NEARLY TWO WEEKS.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/...
ON TUESDAY...A FAIRLY POTENT SECONDARY SHORTWAVE WILL DROP SOUTHEAST
AROUND THE BACKSIDE OF THE EASTERN CANADIAN UPPER LOW...WITH ITS
AXIS PUSHING THROUGH THE CWA BETWEEN THE LATE MORNING AND EARLY
AFTERNOON HOURS...ALONG WITH AN ASSOCIATED SECONDARY SURFACE TROUGH.
LIFT FROM THESE FEATURES WILL INTERACT WITH LAKE-DRIVEN INSTABILITY
EARLY IN THE DAY...AND THEN DIURNALLY-DRIVEN INSTABILITY LATER ON TO
PRODUCE SOME MORE SCATTERED CONVECTION...THOUGH RELATIVELY LIMITED
MOISTURE SHOULD ACT TO KEEP THIS ACTIVITY FROM BECOMING MORE
NUMEROUS/WIDESPREAD. HAVE CONTINUED WITH A RANGE OF CHANCE POPS TO
COVER THIS CONVECTION...WITH THE HIGHEST PROBABILITIES RESERVED FOR
THE NORTH COUNTRY...WHERE THERE WILL BE STRONGER LIFT AND SOMEWHAT
DEEPER MOISTURE. ALL OF THIS SHOULD END BY EARLY EVENING WITH
THE PASSAGE OF THE MAIN SHORTWAVE TROUGH...WITH A MIX OF SUN AND
CLOUDS AND SOMEWHAT BREEZY CONDITIONS OTHERWISE CHARACTERIZING THE
DAY. WITH 850 MB TEMPS OF ROUGHLY +11C TO +14C IN PLACE AND DECENT
MIXING EXPECTED...HIGH TEMPS TUESDAY SHOULD AVERAGE OUT RIGHT AROUND
NORMAL...OR IN THE UPPER 70S TO LOWER 80S.

FOLLOWING THE PASSAGE OF THIS SHORTWAVE...DRIER AND QUIET CONDITIONS
WILL RETURN FOR TUESDAY NIGHT AND WEDNESDAY AS SURFACE HIGH PRESSURE
BUILDS EAST FROM THE CENTRAL GREAT LAKES AND ONTARIO...AND HEIGHTS
REBOUND ALOFT. WITH THE SURFACE HIGH PARKED DIRECTLY OVERHEAD...
WEDNESDAY SHOULD TURN OUT TO BE THE NICEST DAY OF THE UPCOMING
WEEK...WITH ONLY SOME CIRRUS-LEVEL CLOUDINESS SPREADING ACROSS THE
AREA DURING THE AFTERNOON AS WARM ADVECTION COMMENCES ALOFT. UNDER
LIGHT WINDS AND A FAIR AMOUNT OF SUN...850 MB TEMPS OF +11C TO +14C
SHOULD ONCE AGAIN SUPPORT WIDESPREAD HIGHS IN THE UPPER 70S TO LOWER
80S...AND THIS WILL BE COUPLED WITH COMFORTABLE HUMIDITY LEVELS AS
SURFACE DEWPOINTS ARE EXPECTED TO REMAIN IN THE MID TO UPPER 50S.

WEDNESDAY NIGHT THROUGH THURSDAY NIGHT...THE SURFACE HIGH WILL SLIDE
EAST AND EVENTUALLY DRIFT OFF THE ATLANTIC COAST...ALLOWING A WARM
FRONT TO PUSH INTO THE AREA FROM THE CENTRAL LAKES AND OHIO
VALLEY...IN ADVANCE OF UPPER RIDGING SLIDING EASTWARD FROM THE
MISSISSIPPI VALLEY. THE OPPORTUNITY FOR CONVECTION WILL RETURN AS
THE WARM FRONT PUSHES INTO OUR AREA...WITH THE NAM/GFS/GEM/ECMWF ALL
HINTING AT THE POTENTIAL FOR ONE OR MORE MESOSCALE CONVECTIVE
SYSTEMS TO AFFECT THE AREA GIVEN OUR FAVORABLE POSITION ON THE EDGE
OF THE BUILDING UPPER RIDGE...AND SEVERAL SHORTWAVES SLIDING THROUGH
THE PREVAILING WEST-NORTHWESTERLY FLOW ALOFT. GIVEN THE INHERENT
UNCERTAINTIES IN TRYING TO TIME AND PLACE THESE FEATURES THIS FAR
OUT...WILL JUST CONTINUE TO BROADBRUSH LOW CHANCE POPS FOR NOW...
THOUGH THIS PERIOD WILL NEED TO BE CLOSELY WATCHED IN UPCOMING
DAYS.

DURING THIS LATTER HALF OF THE PERIOD...WE CAN ALSO EXPECT
SUMMERTIME EXPECT HEAT AND HUMIDITY TO MAKE A RETURN AS WARMER AND
MORE HUMID AIR ASSOCIATED WITH THE ADVANCING RIDGE FLOODS BACK INTO
OUR REGION. 850 MB TEMPS SHOULD CLIMB BACK TO BETWEEN +16C AND +19C
BY THURSDAY AFTERNOON...WHICH WILL BE SUPPORTIVE OF HIGHS WELL INTO
THE 80S OUTSIDE OF ANY CONVECTION...WHILE SURFACE DEWPOINTS RISE
BACK TO THE UPPER 60S AND LOWER 70S.

&&

.LONG TERM /FRIDAY THROUGH SUNDAY/...
FRIDAY STILL APPEARS TO BE THE HOTTEST AND MOST UNCOMFORTABLE DAY
OF THE UPCOMING WEEK. 850 MB TEMPS WILL PEAK IN THE +18C TO +21C
RANGE AS THE AXIS OF THE UPPER RIDGE PASSES BY JUST TO OUR
SOUTH...AND SUCH READINGS SHOULD BE SUPPORTIVE OF HIGHS IN THE UPPER
80S TO MID 90S...WITH THE HOTTEST READINGS FOUND AWAY FROM ANY LAKE
INFLUENCES. COUPLED WITH THE HEAT...HUMIDITY LEVELS WILL REMAIN
OPPRESSIVE...WITH SURFACE DEWPOINTS LINGERING WITHIN A FEW NOTCHES
OF THE 70 DEGREE MARK.

AS THE DAY PROGRESSES...A WEAK SURFACE COOL FRONT WILL SLIDE
SOUTHEAST INTO THE AREA FROM THE CENTRAL GREAT LAKES...IN
ASSOCIATION WITH A DECENT SHORTWAVE TROUGH SLIDING EAST-SOUTHEAST
ACROSS ONTARIO PROVINCE. THIS FEATURE SHOULD HELP TO TRIGGER AT
LEAST SOME MORE SCATTERED SHOWERS AND THUNDERSTORMS AS IT SLIDES
THROUGH THE AREA FRIDAY AFTERNOON AND EVENING...FOR WHICH CHANCE
POPS REMAIN IN THE FORECAST.

FOLLOWING THE PASSAGE OF THIS COOL FRONT FRIDAY EVENING...HIGH
PRESSURE WITH SLIGHTLY DRIER/LESS HUMID AIR WILL BUILD EAST ACROSS
THE GREAT LAKES SATURDAY AND SUNDAY. THIS WILL SET THE STAGE FOR
MAINLY DRY WEATHER BOTH DAYS...ALONG WITH SOMEWHAT LESS
UNCOMFORTABLE TEMPERATURES AND HUMIDITY LEVELS. SFC DEWPOINTS WILL
DROP BACK A BIT TO THE MID 60S...WHILE 850 MB TEMPS WILL SLIDE BACK
ONLY TO THE +14C TO +17C RANGE...WHICH WILL STILL BE SUPPORTIVE OF
HIGHS WELL INTO THE 80S BOTH DAYS.

&&

.AVIATION /16Z MONDAY THROUGH FRIDAY/...
VFR CONDITIONS WILL BE IN PLACE EARLY THIS MORNING...DESPITE THE
PRESENCE OF A STATIONARY FRONT THAT EXTENDS FROM SOUTH OF BUFFALO TO
ABOUT ELMIRA AND SCRANTON. SHOWERS OVER THE SRN TIER ARE JUST NOW
STARTING TO DOT THE KBUF RADAR. THIS COVERAGE WILL GRADUALLY
INCREASE TO THE NORTH AS THE FRONTS LIFTS NORTHEAST DURING THE
COURSE OF THE MORNING.

DESPITE THIS ACTIVITY...VFR CONDITIONS WILL PREVAIL WITH ONLY
LOCALIZED MVFR CIGS/VSBYS IN HEAVIER SHRA/TSRA. IN THE WAKE OF THE
WARM FRONT DURING THE MIDDAY AND AFTERNOON...THERE WILL BE THE RISK
FOR SOME STRONGER CONVECTION. STORMS COULD BECOME STRONG TO
SEVERE...ESPECIALLY FROM THE FINGER LAKES EASTWARD.

VFR CONDITIONS ARE THEN FORECAST FOR TONIGHT...ALTHOUGH SOME
LOCALIZED FOG COULD DEVELOP OVERNIGHT WHERE HEAVIER RAINFALL
OCCURRED FROM THE AFTERNOON.

OUTLOOK...
TUESDAY...VFR/MVFR WITH A CHANCE OF SHRA/TSRA.
WEDNESDAY AND THURSDAY...VFR.
FRIDAY...VFR/MVFR WITH A CHANCE OF SHRA/TSRA.

&&

.MARINE...
A WEAK WARM FRONTAL BOUNDARY OVER SOUTHERN NEW YORK WILL LIFT
NORTHEAST ACROSS LAKES ERIE AND ONTARIO TODAY. WHILE WINDS AND WAVES
WILL REMAIN BELOW SMALL CRAFT CRITERIA...THERE WILL BE THE RISK OF
THUNDERSTORMS.

THIS RISK WILL BE TEMPORARILY REMOVED FROM THE LAKES IN THE WAKE OF
THE FRONT TONIGHT. GENERALLY MODERATE WESTERLIES WILL BE IN PLACE
WITH MINIMAL WAVE ACTION.

FOR TUESDAY...THE PASSING OF A VIGOROUS UPPER LEVEL DISTURBANCE
COULD GENERATE MORE SCATTERED THUNDERSTORMS. A HIGHER RISK WILL BE
FOUND ON LAKE ONTARIO. WINDS TUESDAY WILL FRESHEN FROM THE WEST-
SOUTHWEST... AND THIS WILL PRODUCE WAVES OF 2-4 FEET...WHICH IS JUST
UNDER SCA CRITERIA.

CALMER CONDITIONS CAN BE EXPECTED TUESDAY NIGHT AND WEDNESDAY AS
HIGH PRESSURE WILL BUILD ACROSS THE LOWER LAKES.
