AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
541 PM EDT TUE JUN 24 2014

.SYNOPSIS...
LOW PRESSURE WILL MOVE THROUGH THE CENTRAL GREAT LAKES AND INTO
QUEBEC PROVINCE TONIGHT. ITS ASSOCIATED COLD FRONT WILL BRING
SHOWERS AND THUNDERSTORMS TO THE AREA THIS AFTERNOON THROUGH
WEDNESDAY. THE FRONT WILL PASS THROUGH THE REGION WEDNESDAY NIGHT
FOLLOWED BY HIGH PRESSURE AND FAIR WEATHER THROUGH FRIDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
CONVECTION DEVELOPING RAPIDLY OVER WESTERN NEW YORK AND POINTS SOUTH
AND WEST.  EXPECT CONVECTION TO SPREAD INTO FINGER LAKES AND NORTH
COUNTRY 22Z-02Z.

WITH PWATS APPROACHING 2.00 INCHES TODAY...MODEST INSTABILITY
(BUFKIT SOUNDINGS SHOWING 500-1000 J/KG) AND A DEEP WARM LAYER (WBZ
NEAR 12K)...THE ATMOSPHERE WILL BE PRIMED FOR HEAVY RAIN WITH ANY
THUNDERSTORMS. HAVE MEDIUM CONFIDENCE THAT CONVECTION THIS AFTERNOON
INTO EARLY TONIGHT COULD POTENTIALLY PRODUCE RAINFALL RATES UP TO 2
INCHES PER HOUR...ESPECIALLY IF CONVECTIVE LINES ORIENT THEMSELVES
FROM SOUTHWEST TO NORTHEAST WHICH WILL RESULT IN PERSISTENT
DOWNPOURS.  FLASH FLOOD WATCH IS IN EFFECT FOR WESTERN NEW YORK
COUNTIES ALONG AN WEST OF THE GENESEE RIVER UNTIL 04Z WED. THIS
INCLUDES BUFFALO...ROCHESTER...JAMESTOWN...AND NIAGARA FALLS.

ADDITIONALLY...A FEW OF THE STRONGER STORMS THIS EVENING MAY PRODUCE
SOME GUSTY WINDS...ISOLATED GUSTS UP TO 50 KNOTS POSSIBLE.

MORE SHOWERS AND THUNDERSTORMS WILL DEVELOP OVERNIGHT INTO WEDNESDAY
ALONG AND AHEAD OF SURFACE FRONT THAT WILL BE SLOWLY MOVING
SOUTHESTWARD ACROSS THE AREA.  PWATS AROUND 2 INCHES AND CONTINUED
INSTABILITY MAY RESULT IN ADDITIONAL HEAVY RAINFALL POTENTIAL
ESPECIALLY EAST OF GENESEE VALLEY.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
WEDNESDAY NIGHT A WAVE OF LOW PRESSURE TRACKING ALONG A COLD FRONT
STRETCHED ACROSS CENTRAL NEW YORK WILL SHIFT EAST INTO NEW ENGLAND.
THIS WILL BE STEERED ALONG BY A SHARP MID-LEVEL SHORTWAVE SHIFTING
EAST ACROSS THE LOWER GREAT LAKES. MOST OF THE SYNOPTIC MOISTURE AND
FORCING WILL ALSO SHIFT EAST WITH THE SURFACE WAVE AS A DRIER
NORTHWEST FLOW DEVELOPS BEHIND THE COLD FRONT. THIS SHOULD BRING AN
END TO THE LARGE MAJORITY OF SHOWER AND THUNDERSTORM ACTIVITY ACROSS
CENTRAL NEW YORK WITH THE ENTIRE FORECAST AREA LARGELY DRY BY
EARLY THURSDAY.

MODEL MOISTURE PROFILES SHOW PLENTY OF LOW LEVEL MOISTURE WILL
LINGER BEHIND THE FRONT SO CLOUDY SKIES WILL LINGER THROUGH
WEDNESDAY NIGHT AND MUCH OF THURSDAY. THE UPSLOPE FLOW OFF THE LAKES
MAY EVEN ALLOW FOR SOME STRAY SPRINKLES OR LIGHT SHOWER ACROSS THE
HIGHER TERRAIN ON THURSDAY MORNING. HIGH PRESSURE WILL SETTLE OVER
NEW YORK FOR THE REMAINDER OF THE WEEK KEEPING DRY CONDITIONS WITH A
MUCH BETTER OPPORTUNITY FOR SUNSHINE BY FRIDAY. HUMIDITY LEVELS WILL
ALSO BE MUCH MORE COMFORTABLE AS DEWPOINTS DROP FROM THE MID 60S
WEDNESDAY NIGHT TO MID 50S BY FRIDAY AFTERNOON. SURFACE TEMPS WILL
AVERAGE NEAR SEASONABLE LEVELS WITH HIGHS IN THE MID 70S TO LOW 80S
AND LOWS FALLING DOWN TO THE MID 50S TO AROUND 60 AT NIGHT.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
HIGH PRESSURE CENTERED OVER NEW YORK AND NEW ENGLAND ON SATURDAY
WILL SETTLE SOUTH OFF THE EAST COAST BY EARLY NEXT WEEK. A SOUTHERLY
FLOW ON THE WEST SIDE OF THE SURFACE HIGH WILL SEND WARMTH AND
HUMIDITY FROM THE GULF OF MEXICO NORTHWARD WHILE AN IMPRESSIVE 588DM
RIDGE BUILDS OVER THE OHIO VALLEY AND LOWER GREAT LAKES. EXPECT
TEMPERATURES TO REACH 10 OR MORE DEGREES ABOVE NORMAL THROUGH THE
LONG TERM PERIOD WITH THE ADDED EFFECTS OF HIGH HUMIDITY PUSHING
HEAT INDEX READINGS INTO THE MID 90S IN SPOTS. THE COMBINATION OF
THE HEAT AND HUMIDITY WILL PRODUCE AN ENVIRONMENT FOR THE
DEVELOPMENT OF DIURNAL SHOWERS AND THUNDERSTORMS SUNDAY...MONDAY AND
ESPECIALLY POSSIBLE TUESDAY WHERE MEDIUM RANGE GUIDANCE SHOWS THE
POTENTIAL FOR A SIGNIFICANT SHORTWAVE TO DRIVE CONVECTION ACROSS OUR
REGION.

&&

.AVIATION /22Z TUESDAY THROUGH SUNDAY/...
SCATTERED CONVECTION CONTINUES TO DEVELOP ACROSS WNY THIS AFTERNOON.
CURRENT THINKING IS THAT LAKE SHADOWING SHOULD KEEP KBUF/KIAG CLEAR
OF CONVECTION FOR AT LEAST THE NEXT 2-3 HOURS...THOUGH SCT SHRA/TSRA
WILL BE FOUND FARTHER INLAND ACROSS WNY. TSRA CURRENTLY MOVING
THROUGH KROC SHOULD CLEAR OUT AFTER 22Z...AGAIN AT LEAST FOR 1-2
HOURS.

AM CONTINUING TO MONITOR A BROKEN COMPLEX OF SHRA/TSRA TO OUR WEST
EXTENDING FROM SRN ONTARIO TO EAST OF CYYZ. THIS COMPLEX IS
ASSOCIATED WITH A WEAK SHORTWAVE ALOFT AND MAY LEAD TO ANOTHER ROUND
OF TSRA ACROSS WRN/NCNTRL NY BETWEEN 00-06Z...WITH A GENERAL
DOWNTREND IN CONVECTIVE INTENSITY AND COVERAGE AFTER 06Z WITH THE
LOSS OF DIURNAL HEATING.

AFTER A QUIET PERIOD DURING THE MORNING HOURS...ANOTHER ROUND OF
WIDESPREAD CONVECTION WILL BE LIKELY WED AFTERNOON.

OUTLOOK...
WEDNESDAY NIGHT...SHOWERS AND THUNDERSTORMS.
THURSDAY THROUGH SUNDAY...NO SIGNIFICANT WEATHER EXPECTED.

&&

.MARINE...
IT WILL BE UNSETTLED DURING THE NEXT 36 HOURS AS THEIR WILL BE THE
RISK OF THUNDERSTORMS. MARINERS SHOULD THUS BE ALERT FOR SPECIAL
MARINE WARNINGS THROUGH WEDNESDAY.

MODERATE SOUTHERLIES WILL BE FOUND ACROSS THE LOWER GREAT LAKES THIS
AFTERNOON WITH THE OFFSHORE FLOW PUSHING THE HIGHEST WAVES INTO
CANADIAN WATERS. AS A COLD FRONT APPROACHES TONIGHT...WINDS WILL
VEER TO THE SOUTHWEST WHILE WAVES WILL REMAIN BELOW SMALL CRAFT
CRITERIA.

THE FRONTAL BOUNDARY WILL STALL JUST TO THE SOUTH OF LAKES ERIE AND
ONTARIO ON WEDNESDAY...SO UNSETTLED CONDITIONS WILL LIKELY REMAIN IN
PLACE ALTHOUGH WINDS WILL GENERALLY BE LIGHT.

FAIR WEATHER WILL RETURN TO THE LOWER GREAT LAKES FOR THURSDAY
THROUGH SATURDAY.
