Area forecast discussion, Jul 11, 1:34 PM EDT, 1 hour 28 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
134 PM EDT WED JUL 11 2007
.SYNOPSIS...
LOW PRESSURE TRACKING NORTHEAST FROM ONTARIO INTO QUEBEC WILL PUSH A
COLD FRONT ACROSS OUR REGION TODAY FOLLOWED BY NOTICEABLY
COOLER...MORE COMFORTABLE CONDITIONS TONIGHT AND THURSDAY. THE
COOLER CONDITIONS WILL PERSIST THE REST OF THE WEEK. IT WILL BE
GENERALLY DRY AS WELL...THOUGH THERE WILL BE A RISK OF A SHOWER OR
TWO THURSDAY NIGHT AND FRIDAY AS AN UPPER LEVEL DISTURBANCE CROSSES
THE REGION.
&&
.NEAR TERM /THROUGH TONIGHT/...
THE APPROACHING COLD FRONT IS ON OUR WESTERN DOORSTEP AS OF
14Z...WITH SEVERAL CLUSTERS OF CONVECTION AFFECTING BOTH THE EASTERN
AND WESTERN ENDS OF THE CWA AT THIS TIME. LOOKING AT EVERYTHING AS A
WHOLE...THE LEADING BATCH OF THE PRECIP IS ALREADY MUCH FURTHER EAST
THAN WAS ADVERTISED IN THE PREVIOUS FORECAST...WHILE THE OVERALL
AREAL COVERAGE IS STILL MUCH MORE SPOTTY/SCATTERED THAN PREVIOUS
THINKING...OR MORE IN LINE WITH THE FASTER AND DRIER GFS AS OPPOSED
TO THE SLOWER AND WETTER NAM. THAT SAID...OVER THE PAST HOUR THE
CONVECTION OVER WESTERN NY HAS BEEN SHOWING SIGNS OF BECOMING MORE
ORGANIZED AND CONCENTRATED...WHICH MAKES SENSE CONSIDERING WE ARE
NOW GETTING A LITTLE HEATING...AND THE FRONT AND ITS ASSOCIATED
UPPER SUPPORT /RRQ OF A WELL-DEFINED 300 MB JET STREAK/ ARE NOW
WORKING INTO THE AREA FROM THE WEST. WOULD TEND TO THINK THAT THE
CONVECTION WOULD TEND TO CONTINUE TO INCREASE IN STRENGTH AND
COVERAGE AS IT WORKS EAST LATE THIS MORNING AND AFTERNOON...WITH
ENOUGH DYNAMICS AND INSTABILITY /SBCAPES OF AROUND 1000 J/KG/
EXPECTED TO BE AVAILABLE TO WARRANT A CONTINUATION OF CATEGORICAL
POPS FROM THE GENESEE VALLEY EASTWARD. FURTHER TO THE WEST...EXPECT
THAT THE AREAL COVERAGE WILL NOT HAVE THE OPPORTUNITY TO GET AS
WIDESPREAD PRIOR TO THE FROPA...SO HAVE OPTED TO DROP POPS BACK TO
THE LIKELY RANGE AND USE THE FEW QUALIFIER ACROSS FAR WESTERN NY.
AS FOR THE TIMING OF THE ENDING OF THE PRECIP...THAT STILL LOOKS
REAL GOOD...GENERALLY EARLY AFTERNOON WEST...MID AFTERNOON CENTRAL
AND LATE AFTERNOON EAST WITH A GOOD CLEARING TREND FOLLOWING
THEREAFTER...SO HAVE ONLY MADE MINOR ADJUSTMENTS TO THAT IN THE
GRIDS/TEXT PRODS.
AS FOR A SEVERE THREAT...THE BEST CHANCE FOR ANY SEVERE WX APPEARS
TO BE FROM OUR FAR EASTERN ZONES EASTWARD...WHICH WILL SEE THE
MOST HEATING/INSTABILITY AND MOST ORGANIZED CONVECTION PER THE
LATEST SPC DAY 1 OUTLOOK. FURTHER WEST...FAIRLY EXTENSIVE CLOUD
COVER SHOULD RESULT IN A MINIMAL SEVERE THREAT...BUT WELL BE
MONITORING THE SITUATION CLOSELY.
AS FOR TEMPS...BASED ON CURRENT OBS /WHICH ARE ALREADY AT OR ABOVE
FORECAST MAXES/ AND RADAR AND SATELLITE TRENDS...HAVE OPTED TO RAISE
THESE A SOLID CATEGORY OR TWO...PARTICULARLY FROM THE GENESEE VALLEY
EASTWARD TO THE NORTH COUNTRY. ACROSS OUR FAR EASTERN ZONES...TEMPS
ARE ALREADY IN THE LOWER 80S...AND COULD GET AS HIGH AS THE MID 80S
BEFORE THE PRECIP ARRIVES GIVEN 850 MB TS OF +16/+17C.
OTHERWISE...NO CHANGES BEYOND THE FIRST PERIOD AS MUCH DRIER AND
STABLE CONDITIONS WILL PREVAIL TONIGHT AS HIGH PRESSURE NOSES IN
BEHIND THE FRONT. HIGH CONFIDENCE IN THIS PERIOD OF THE FORECAST.
&&
.SHORT TERM /THURSDAY THROUGH SATURDAY/...
THURSDAY SHOULD BE A PLEASANT DAY WITH HIGHS IN THE 70S AND DRY AIR
PERSISTING. THERE WILL BE AN INCREASE IN CLOUDINESS HOWEVER AS AN
UPPER TROUGH CONTINUES TO DIG INTO THE CENTRAL GREAT LAKES.
SOUNDINGS BECOME MORE UNSTABLE IN THE AFTERNOON BUT WE WILL NOT GO
ANY HIGHER THAN THE 20 POPS THAT ARE ALREADY IN THE GRIDS. THE
PREVIOUS GRIDS ALSO LOOK GOOD FOR THURSDAY NIGHT AND FRIDAY WITH
CHANCE POPS AS THE UPPER TROUGH MOVES FURTHER EAST WITH SOME SHORT
WAVE ENERGY SWINGING THROUGH THE BASE OF THE TROUGH. THERE SHOULD BE
QUITE A BIT OF CLOUDINESS AS WELL KEEPING HIGHS ON FRIDAY IN THE
LOWS 70S WITH SOME UPPER 60S ACROSS THE HIGHER ELEVATIONS. WE WILL
ADJUST THOSE GRIDS DOWN A BIT FROM THE PREVIOUS PUBLISH.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
FAIRLY PLEASANT SUMMER WX IN STORE THROUGH THIS PERIOD ALTHOUGH A
GENERAL WARMING TREND WILL BE IN STORE AS UPPER FLOW FLATTENS OUT
AND SFC RIDGING TAKES HOLD. WE DO HAVE A WEAK TROF DROPPING ACROSS
THE AREA SAT NT WITH CHC POPS BUT IT LOOKS TO CLEAR REGION EARLY
SUNDAY SO WILL GO FOR A DRY DAY. 850MB TEMPS OF 10C OR SO SUPPORT
U70S. RIDGE BEGINS TO BUILD ON MONDAY SO WILL BUMP TEMPS UP A
FEW...THEN SOME LOW CHC POPS MONDAY NIGHT WITH A BIT OF A WARM
FRONT LIFTING BY TO OUR NORTH AND WEST. TUES AND WED LOOK QUITE
SUMMERY. BOUNDARY SHOULD STAY TO OUR NORTH SO WE WILL BE
ENTRENCHED IN WARM SECTOR WITH 850MB TEMPS RISING TO
16-18C...EASILY SUPPORTING M-U 80S ONCE AGAIN. CANT RULE OUT
AFTERNOON CONVECTION BUT POPS SHOULD REMAIN NO HIGHER THAN 20 BOTH DAYS.
&&
.AVIATION /17Z WEDNESDAY THROUGH SUNDAY/...
SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A SHARP COLD FRONT WILL
CONTINUE TO CROSS OUR EASTERN SECTIONS THIS AFTERNOON. CONDITIONS
WILL LOWER TO IFR AT TIMES WITH THE STORMS...BUT SHOULD IMPROVE TO
VFR A COUPLE HOURS AFTER FROPA...OR BY 20Z AT KBUF/KIAG...22Z AT
KJHW AND KROC...AND BY 00Z AT KART. FINE VFR FLYING CONDITIONS
TONIGHT AND THURSDAY WITH SOME SOME SCATD CU.
LOOKING FURTHER OUT IN TIME...LOOK FOR GENERALLY VFR CONDITIONS ON
THROUGH THE WEEKEND WITH POSSIBLE BRIEF LOWERINGS TO MVFR
THURSDAY NIGHT AND FRIDAY IN A FEW SCATD SHOWERS...AND AGAIN
SATURDAY NIGHT WITH A WEAK FRONTAL PASSAGE.
&&
.MARINE...
WINDS WILL TURN BRISK WEST TO NORTHWEST FOR AWHILE THIS EVENING
FOLLOWING THE FRONTAL PASSAGE BUT DIMINISH QUICKLY TOWARD MORNING.
THESE WINDS WILL BE FAVORABLE FOR WAVES TO BUILD TO 4 FEET OR
SLIGHTLY HIGHER ALONG THE SOUTH SHORE OF LAKE ONTARIO FROM ABOUT
HAMLIN BEACH TO MEXICO BAY LATER TONIGHT SO THE SMALL CRAFT
ADVISORY WILL BE CONTINUE IN THAT AREA.
WINDS WILL BE FAIRLY LIGHT ON THURSDAY EXCEPT FRESHEN UP A BIT OUT
OF THE SOUTHWEST OVER EASTERN LAKE ERIE AND THE BUFFALO HARBOR
DURING THE AFTERNOON. LIGHTER WINDS WILL PREVAIL FRIDAY AND
THROUGH THE WEEKEND.
&&
.HYDROLOGY...
OUR REGION HAS BEEN VERY DRY BUT THE MORNING/MIDDAY THUNDERSTORMS
PROVIDED A GOOD DRENCHING FOR MUCH OF THE AREA FROM THE SOUTHERN
TIER INTO THE GENESEE VALLEY. RADAR INDICATIONS ARE THAT AS MUCH
AS ONE TO TWO INCHES FELL IN SOME SPOTS...PEAKING FROM EASTERN
CHAUTAUQUA INTO WESTERN CATTARAUGUS AND FAR SOUTHERN ERIE
COUNTIES. MUCH LESS FELL IN THE BUFFALO AREA HOWEVER...GENERALLY
UNDER A QUARTER INCH. LOOK FOR A SOLID ONE HALF TO ONE INCH ACROSS
THE BLACK RIVER BASIN LATER TODAY.
