AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
525 PM EDT TUE APR 26 2011

.SYNOPSIS...
A LINE OF SHOWERS AND GUSTY THUNDERSTORMS WILL CROSS THE AREA FROM
WEST TO EAST THIS EVENING WITH POSSIBLE STRONG WINDS AND HAIL.
CLOUDS AND SOME SUNSHINE ON WEDNESDAY AND REMAINING WARM WITH
INCREASING LIKELIHOOD OF SHOWERS AND THUNDERSTORMS LATER IN THE DAY
AND ESPECIALLY AT NIGHT AHEAD OF A COLD FRONT. A COLD FRONT WILL
CROSS THE REGION THURSDAY MORNING WITH TEMPERATURES DROPPING BACK
CLOSE TO AVERAGE. DRY WEATHER WILL FINALLY RETURN BY SATURDAY ALONG
WITH MILD SPRING TEMPERATURES.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AT 19Z WATER VAPOR IMAGERY AND VISIBLE SATELLITE SHOW TWO BOUNDARIES
THAT WILL IMPACT OUR CWA AREA WITH SHOWERS AND STRONG TO SEVERE
THUNDERSTORMS THIS AFTERNOON AND THROUGH THE OVERNIGHT PERIOD. ONE
BOUNDARY...ACROSS THE FINGER LAKES REGION WILL BRING SHOWERS AND
THUNDERSTORMS ACROSS THE FINGER LAKES AND THE NORTH COUNTRY THIS
LATE AFTERNOON. THE SECOND BOUNDARY IS LOCATED ACROSS EASTERN OHIO
AND SOUTHWESTERN ONTARIO WITH ADDITIONAL SHOWER AND THUNDERSTORM
ACTIVITY FORMING ON THE LEADING EDGE OF A MID LEVEL 80 KNOT SPEED
MAX AND SFC CONVERGENCE.

AT THE SFC A WARM FRONT IS LEFT DRAPED ROUGHLY ALONG THE THRUWAY
THIS LATE AFTERNOON...NORTH OF BUFFALO AND SOUTH OF BOTH NIAGARA
FALLS AND ROCHESTER. SOUTH OF THIS WARM FRONT TEMPERATURES WARMED
INTO THE UPPER 70S TO EVEN A FEW 80S UNDER MOSTLY SUNNY SKIES.
EXPECT THIS WARM FRONT TO SLOWLY LIFT NORTHWARD THROUGH THE
OVERNIGHT.

ALOFT A CLOSED LOW IS LOCATED ACROSS THE WESTERN GREAT LAKES WITH AN
EXPANSIVE RIDGE OF HIGH PRESSURE ACROSS THE WESTERN ATLANTIC AND
EAST COAST.

SCATTERED SHOWERS AND THUNDERSTORMS WILL REMAIN ACROSS WESTERN AND
CENTRAL NEW YORK IN THE AFTERNOON HEATING AHEAD OF THIS SECONDARY
BOUNDARY SEEN ON SATELLITE AND ON THE FRINGE OF THE UPPER LEVEL
CLOSED LOW. INSTABILITY REMAINS ACROSS THE ENTIRE CWA WITH CAPES
APPROACHING 500 TO 1000 J/KG...AND LI'S -2 TO -4. NORTH OF THE WARM
FRONT STORM HELICITY VALUES REMAIN IMPRESSIVE EARLY AND STORMS
TRACKING ACROSS THE WARM FRONT WILL BE MONITORED FOR ROTATION.

TRACKING THIS SECONDARY BOUNDARY EXPECT A LINE OF SHOWERS AND
THUNDERSTORMS TO ENTER WESTERN BETWEEN 5 PM AND 7PM...AND THEN TRACK
QUICKLY EASTWARD ACROSS THE REGION. A FEW OF THESE STORMS WILL
LIKELY BECOME STRONG OR SEVERE WITH 0-6KM SHEAR REACHING 40 TO 45
KNOTS. PWATS APPROACH +2 TO +3 SD THIS LATE AFTERNOON AND
EVENING...SO IN ADDITION TO THE GUSTY WINDS AND POSSIBLE HAIL...ANY
STORM HAS THE POTENTIAL TO PRODUCE A QUICK DOWNPOUR. TOWARDS THE
NORTH COUNTRY EXPECT SOME WEAKENING TO THESE STORMS AS THEY RUN INTO
SLIGHTLY LESS INSTABILITY. CURRENT THINKING IS DOWNPOURS WILL BE BRIEF
AND SCATTERED ENOUGH THAT RIVERS AND CREEKS SHOULD BE ABLE TO HANDLE
THE RAINFALL TONIGHT. HOWEVER ANY TRAINING STORMS CAN LEAD TO LOCAL
HYDRO ISSUES TONIGHT.

BEHIND THIS LINE OF SHOWERS AND THUNDERSTORMS EXPECT SKIES TO
CLEAR...ESPECIALLY ACROSS WESTERN NEW YORK AND THE GENESEE VALLEY.
WITH CLEARING SKIES AND LINGERING MOISTURE IN THE LOWER LEVELS
PATCHY FOG WILL LIKELY DEVELOP OVERNIGHT AND TOWARDS THE DAWN
HOURS. TEMPERATURES TONIGHT WILL REMAIN MILD WITH LOWS IN THE
50S...WITH A FEW 60S IN SPOTS.

TOMORROW WINDS WILL BEGIN TO SHIFT TO SOUTHEAST WELL AHEAD OF THE
NEXT FRONTAL BOUNDARY. THERE MAY BE A LITTLE SFC CONVERGENT SHOWER
ACTIVITY ACROSS THE NORTHERN NIAGARA PENINSULA IN THE MORNING.
ELSEWHERE WITH INSTABILITY REMAINING EVEN IN THE EARLY MORNING HOURS
AND GIVEN THAT WE ARE IN ROUGHLY THE SAME AIRMASS...CANNOT RULE OUT
A SHOWER OR THUNDERSTORM AT ANY TIME TOMORROW UNDER ANY WEAK IMPULSE.
ACTIVITY WILL BECOME MORE WIDESPREAD LATER TOMORROW AND OVERNIGHT
AHEAD OF THE NEXT UPPER LEVEL FEATURE TO SWING ACROSS THE REGION.

TEMPERATURES AT 850 REMAIN +12 TO +14C AND UNDER A CLOUDS AND SOME
SUNSHINE EXPECT TEMPERATURES TOMORROW TO REACH INTO THE 70S ACROSS
THE CWA.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
LOW PRESSURE ACROSS THE OHIO VALLEY WILL LIFT INTO THE CENTRAL LAKES
WEDNESDAY NIGHT...BRINGING A STRONG COLD FRONT ACROSS THE REGION
THURSDAY MORNING. AHEAD OF THIS BOUNDARY...THERE WILL CONTINUE TO BE
A SIGNIFICANT THREAT FOR SEVERE WEATHER. THE REGION WILL BE FIRMLY
IN THE WARM SECTOR AHEAD OF THE BOUNDARY...WITH MODEST SURFACE BASED
CAPES IN PLACE...EVEN OVERNIGHT. WIND FIELDS WILL ALSO BE FAVORABLE
FOR ORGANIZED CONVECTION...WITH SEVERAL RUNS OF THE GFS/NAM
INCREASING 850 MB WINDS TO AROUND 60 KTS...AND THIS IN A SHEARED
ENVIRONMENT. FINALLY WE WILL HAVE A SHORTWAVE AND FRONTAL BOUNDARY
CROSS...PROVIDING A POTENTIAL FOCUS FOR STORMS. THE MAIN LIMITING
FACTOR WILL BE THE TIMING...WITH ALL OF THIS COMING LATE WEDNESDAY
NIGHT...WHEN THE ATMOSPHERE TYPICALLY STARTS TO STABILIZE AS IT WILL
BE FAR REMOVED FROM DAYTIME HEATING. WHILE IT IS STILL A WAYS OFF
FOR ENHANCED WORDING...WILL CONTINUE A STRONG MENTION IN THE HWO FOR
THE POTENTIAL OF SEVERE WEATHER. THIS IS LIKELY TO CONTINUE TO BE A
DIFFICULT FORECAST UPSTREAM CONVECTION DEVELOPS WEDNESDAY AFTERNOON
AND EVENING. THIS APPEARS TO BE AN EVENT WHERE STORMS WILL DEVELOP
UPSTREAM AND MOVE INTO THE AREA...RATHER THAN DEVELOP ACROSS OUR
REGION.

IN ADDITION TO THE SEVERE WEATHER THREAT...ADDITIONAL RAINFALL MAY
BE ENOUGH TO CAUSE LOCALIZED FLOODING. EXPECT ANY FLOODING TO BE
LOCALIZED...POTENTIALLY FROM TRAINING OR PERSISTENT CELLS...BUT
GIVEN THE WET CONDITIONS ALREADY...ANY RAINFALL IN EXCESS OF AN INCH
BEARS WATCHING.

MODEL AGREEMENT IS FAIRLY GOOD IN BRINGING THE BOUNDARY THROUGH THE
REGION THURSDAY MORNING...WITH THE SLOWER NAM/SREF AND THE FASTER
GFS/EUROPEAN ONLY A COUPLE HOURS APART ON TIMING. THE SEVERE WEATHER
THREAT WILL EFFECTIVELY END WITH THE FRONTAL PASSAGE...THOUGH
SOUTHWEST WINDS SHOULD PICK UP BEHIND IT...WITH GUSTS OF AT LEAST 40
MPH LIKELY ON THE NIAGARA FRONTIER. OUTSIDE OF POTENTIAL TIMING
ERRORS IN THE FRONTAL PASSAGE...EXPECT THE POST FRONT ENVIRONMENT TO
BE RAIN-FREE. TEMPERATURES WEDNESDAY NIGHT SHOULD BE UNSEASONABLY
WARM...THEN HOLD STEADY OR DROP DURING THE DAY THURSDAY WITH THE
PASSAGE OF THE FRONT.

THE NEXT FEATURE TO INFLUENCE OUR WEATHER WILL BE MUCH MORE
MODEST...AS A 500 MB TROF PASSES TO THE NORTH OF THE REGION. MODELS
FAIRLY SPREAD ON THE TIMING OF THE PASSAGE OF THE TROF...BUT
CONSENSUS OF THE 12Z RUNS IS A FEW HOURS SLOWER THAN PREVIOUS
FORECAST. CONTINUE WITH LIKELY POPS WITH THIS FEATURE...CENTERED
AROUND 12Z FRI MORNING. WHILE A 3 TO 6 HOUR PERIOD OF SHOWERS IS
LIKELY...THE DAY SHOULD NOT BE A WASH OUT...AND SHOWERS SHOULD NOT
BE HEAVY ENOUGH TO CAUSE ANY ADDITIONAL FLOODING CONCERNS.
TEMPERATURES WILL BE COOLER BEHIND THE FRONT...WITH HIGHS IN THE
UPPER 40S TO LOWER 50S ON FRIDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
OVERALL...LOOKS TO BE A MUCH LESS EVENTFUL PERIOD...WITH GENERALLY
SEASONABLE WEATHER...AND GENERALLY SHOWERY PRECIPITATION ON THE LIGHT
SIDE. HIGH PRESSURE WILL BUILD ACROSS THE REGION FRIDAY NIGHT AND
SATURDAY...WITH FAIR WEATHER LIKELY ACROSS THE REGION. A COUPLE OF
THE 12Z RUNS WERE A BIT SLOWER IN EXITING A SHORTWAVE...BUT FOR NOW
OPT TO KEEP THIS DRY.

INCREASING UNCERTAINTY FOR THE LATTER PORTION OF THE PERIOD...AS THE
GFS/GGEM/EUROPEAN CONTINUE TO OFFER FAIRLY DIFFERENT SOLUTIONS IN
HANDLING THE NEXT SHORTWAVE. WHAT THEY DO AGREE ON...IS THAT IT HAS
NORTHERN AND FAIRLY DRY ROOTS...SO AGAIN PRECIPITATION SHOULD
GENERALLY BE ON THE LIGHT SIDE. BASICALLY KEEP CHANCE POPS GIVEN
DIFFERENCES IN TIMING AMONG THE MODELS...BUT DO UP TO 40 POPS...WITH
SEVERAL RUNS NOW SUPPORTING SOME PRECIPITATION.

FEATURE APPEARS TO EXIT EAST BY TUESDAY...THOUGH THERE IS SOME
CHANCE IT WILL LINGER...SCALE BACK TO 20 SLIGHT CHANCE POPS.

&&

.AVIATION /21Z TUESDAY THROUGH SUNDAY/...
WIDESPREAD CONVECTION ACROSS THE FORECAST AREA THIS
AFTERNOON/EVENING. EXPECT INSTABILITY TO CONTINUE INTO THE EVENING
HOURS WITH THUNDERSTORMS POSSIBLE AT MOST OF THE TAF SITES THROUGH
AROUND 00Z. HEAVIEST LINE OF CONVECTION IS LOCATED ACROSS THE
GENESEE VALLEY MOVING EAST WITH ANOTHER LESSS ORGANIZED LINE OF
SHOWERS MOVING OFF OF LAKE ERIE. HAVE LEFT POSSIBILITY FOR TS IN
ALL TAFS THOUHG 00Z WITH THE EXCEPTION OF KJHW WHICH AS THE
HEAVIEST CONVECTION HAS MOVED OFF TO THE EAST. OTHERWISE FEW
CHANAGES TO THE REST OF THE PACKAGE AT THIS TIME.

PREVIOUS DISCUSSION...BEHIND THE LINE OF CONVECTION...EXPECT SOME CLEARING
WITH CIGS DROPPING TO MVFR FOR A TIME. HAVE ONLY LOWERED VSBYS
INTO MVFR CATEGORY...THOUGH WITH CLEARING CAN SEE SOME IFR VSBYS
IN THE LINGERING HUMID AIRMASS. ADDITIONAL SHOWERS WILL AGAIN
CROSS INTO PORTIONS OF WESTERN NEW YORK TOMORROW MORNING...WITH
THE KIAG TERMINAL THE MOST LIKELY AREA FOR SHOWERS ON A SOUTHEAST
WIND.

WITH INSTABILITY REMAINING THROUGH THE MORNING AND
AFTERNOON...CANNOT RULE OUT A SHOWER AT ANY TIME THROUGH THE
MORNING...THOUGH THE LIKELY TIME PERIOD WILL HOLD OFF TILL AFTER
18Z.

OUTLOOK...
WEDNESDAY NIGHT...MVFR/VFR IN OCCASIONAL SHOWERS AND THUNDERSTORMS.
THURSDAY AND FRIDAY...MVFR/VFR. A CHANCE OF SHOWERS.
SATURDAY...VFR.
SUNDAY...MVFR/VFR IN A CHANCE OF SHOWERS.

&&

.MARINE...
WILL MAINTAIN SMALL CRAFTS ON WESTERN LAKE ONTARIO THROUGH THE
EVENING HOURS AS WAVES WILL BEGIN THIS TIME FRAME AROUND 4 FEET AND
EASTERLY WINDS AT 20 KNOTS. A LINE OF SHOWERS AND THUNDERSTORMS WILL
CROSS LAKE ERIE AND LAKE ONTARIO THIS LATE AFTERNOON AND EVENING
WITH SOME OF THESE STORMS POSSIBLY BECOMING STRONG TO SEVERE. WINDS
TONIGHT WILL DIMINISH AND SOUTHEAST WINDS VEERING TO SOUTHWEST WILL
REMAIN BELOW SMALL CRAFT ACTIVITY THE REMAINDER OF THE NIGHT AND WEDNESDAY.
TOWARDS WEDNESDAY NIGHT EXPECT WINDS AND WAVES TO AGAIN INCREASE
WITH SMALL CRAFTS POSSIBLE.

ANY THUNDERSTORMS LATE THIS AFTERNOON AND EVENING AND AGAIN LATER
WEDNESDAY MAY PRODUCE LOCALLY GUSTY WINDS AND HIGHER WAVES.

&&

.HYDROLOGY...
ON THE RIVERS AND CREEKS...MOST OF THE FASTER RESPONDING CREEKS IN
THE BUFFALO AREA HAVE ALREADY CRESTED. THE EXCEPTION IS ON THE
ELLIOTT CREEK IN WILLIAMSVILLE...WHERE AN EARLY EVENING CREST
WILL LIKELY BE NEAR FLOOD STAGE. THE TYPICALLY SLOW RESPONDING
TONAWANDA CREEK WILL NOT CREST FOR SOME TIME...BUT IT IS POSSIBLE
THAT WILL EVENTUALLY APPROACH FLOOD STAGE...BUT NOT UNTIL MID TO
LATE WEEK.

OVERNIGHT AND WEDNESDAY...PRECIPITATION WILL BE GENERALLY SHOWERY.
IN GENERAL...STORMS WILL BE MOVING FAIRLY FAST...WHICH WILL LIMIT
RAINFALL IN ANY ONE LOCATION. HOWEVER...GIVEN THE WET
ENVIRONMENT...IT WILL ONLY TAKE AN INCH TO START TO CAUSE ISSUES
IN SOME SPOTS...SO WILL HAVE TO MONITOR CAREFULLY FOR ANY SLOW
MOVING HEAVY RAINERS.

THE NEXT FOCUS WILL MOVE THROUGH ON WEDNESDAY NIGHT INTO THURSDAY
MORNING...DROPPING A MEAN OF AROUND A HALF INCH...WITH LOCALLY
HIGHER AMOUNTS IN SLOW MOVING CELLS. THIS MAY BE ENOUGH TO PUSH
SOME OF THE FASTER RESPONDING CREEKS TO FLOOD AGAIN...AND WILL
ALSO HAVE TO MONITOR FOR THE POSSIBILITY OF FLASH FLOODING IF CELLS
DO REDEVELOP OUT AHEAD OF THE BOUNDARY.

&&
