1107 PM EDT SAT AUG 9 2008

...THE SMALL STREAM FLOOD ADVISORY REMAINS IN EFFECT UNTIL 1230 AM 
EDT FOR SOUTHWEST ERIE AND CHAUTAUQUA COUNTIES...

NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATES THAT OVER 2 INCHES 
OF RAIN HAS FALLEN OVER THE PAST 3 HOURS ALONG PORTIONS OF THE 
CHAUTAUQUA RIDGE FROM ARKWRIGHT TO FORESTVILLE...THE CATTARAUGUS 
INDIAN RESERVATION...AND EVANS. MORE SHOWERS MOVING INTO THE AREA 
WILL BRING UP TO A HALF INCH OF ADDITIONAL RAINFALL THROUGH 1230 AM 
EDT.

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY 
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL 
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED 
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
740 PM EDT SAT AUG 9 2008

.SYNOPSIS...
A LOW PRESSURE SYSTEM OVER THE CENTRAL GREAT LAKES AND ITS
ASSOCIATED COLD FRONT WILL DROP SOUTHEAST INTO WESTERN NEW YORK
TONIGHT AND SUNDAY...BRINGING MORE UNSETTLED WEATHER BACK INTO THE
REGION. A FEW MORE SHOWERS AND THUNDERSTORMS ARE FORECAST TO
LINGER INTO MONDAY AND MONDAY NIGHT AS THIS SYSTEM MOVES EAST INTO
NEW ENGLAND...THEN HIGH PRESSURE IS EXPECTED TO BRING A RETURN TO
DRIER AND QUIETER WEATHER FOR TUESDAY.

&&

.NEAR TERM /THROUGH SUNDAY/...
A VERY ACTIVE NIGHT IS AHEAD FOR WESTERN NEW YORK...AS WIDESPREAD
SHOWERS AND THUNDERSTORMS OVER SOUTHERN ONTARIO AND WESTERN LAKE
ONTARIO WILL PIVOT ACROSS OUR REGION. AS OF 22Z (6 PM)...THE
STRONGER STORMS ALONG THE LEADING EDGE OF THE PCPN WERE MOVING TO
THE EAST-NORTHEAST...AND THUS STAYING JUST ON THE NORTHERN FRINGES
OF OUR FORECAST AREA.

AS THE EVENING PROGRESSES THOUGH...THE LARGE OUT OF SEASON UPPER
LEVEL STORM CENTERED OVER THE SOO WILL DROP TO THE SOUTHEAST ACROSS
LAKE HURON AND GEORGIAN BAY. THE CORRESPONDING AREA OF PCPN OVER
SOUTHERN ONTARIO WILL THEN SETTLE OVER OUR REGION. HAVE RAISED POPS
TO 100 FOR THE VAST MAJORITY OF THE REGION FOR TONIGHT...AND WHILE
THERE WILL BE THE RISK OF STRONG TO SEVERE THUNDERSTORMS...WE
BELIEVE THAT THERE MAY BE A GREATER POTENTIAL FOR HEAVY RAINS.

THE LOCALLY RUN MESOSCALE WRF MODELS ARE IN STRONG AGREEMENT OF
HEAVY PCPN COMING FROM THE APPROACHING AREA OF SHRA/TSRA...WITH
AMOUNTS OF ONE TO AS MUCH AS TWO INCHES POSSIBLE. THE BULK OF THE
ACTIVITY WILL OCCUR OVER THE FAR WESTERN COUNTIES BETWEEN 03 AND
07Z...OVER THE FINGER LAKES REGION BETWEEN 05 AND 09Z AND EAST OF
LAKE ONTARIO BETWEEN 09 AND 14Z. THE HIGHER QPF IS ALSO SUGGESTED BY
THE 18Z OPERATIONAL NAM/WRF...AND HAVE USED THIS TO RE-POPULATE THE
GRIDS (THEREBY ADJUSTING QPF FORECAST). THE UPDATED GRIDS AND
WORDED PRODUCTS ARE ON THE STREET. A NEW HWO HAS BEEN ISSUED AS
WELL.

AS FOR SEVERE POTENTIAL...INSTABILITY IS LIMITED WITH LOW DEW PTS
AND WIND FIELDS ARE NOT IMPRESSIVE..BUT COLD POOL WILL LOWER
FREEZING LEVELS DRAMATICALLY SO THERE IS POTENTIAL FOR HAIL.

MODELS ALL SHOW A DRY SLOT PIVOTING INTO WESTERN AREAS TOWARD
DAYBREAK SO WILL LOWER POPS SIGNIFICANTLY...BUT STILL HOLD THEM
IN LOW CHC CATEGORY.

ON SUNDAY...MODELS IN BETTER AGREEMENT NOW IN DROPPING UPPER LOW
ACROSS SRN ONTARIO TO ERN LK ERIE BY AFTERNOON AND THEN DOWN INTO
NRN PA SUN EVENING. SFC FEATURE IS A BIT FURTHER EAST...BUT NOT BY
MUCH...CROSSING FAR WRN NY DURING THE DAY. THIS WILL PLAY HAVOC
WITH OUR WIND FIELDS AND RAINFALL POTENTIAL. FOR NOW...WILL
CONTINUE WITH DRY SLOT SCENARIO INTO CNTRL NY BY EARLY
AFTERNOON...THEN CLOSING OFF. IN WEST...A FAIRLY DRY MORNING WILL
GIVE WAY TO INCR POPS AGAIN IN AFTERNOON AS WRAPAROUND PIVOTS
AROUND THE LOW AS IT PULLS EAST AND SOUTH. WETTEST PERIOD NR LK
ERIE MAY ACTUALLY BE LATER SUN AFTERNOON AND EVENING. AS FOR
WINDS...WILL PLAY THEM SOUTHWEST AND WEST NR LK ERIE AND FAR WRN
LK ONTARIO...BUT L/V TO EASTERLY FOR AWHILE ACROSS E LK ONTARIO
ZONES. THEY SHOULD BE QUITE LIGHT THOUGH AS WELL BE NEAR CENTER OF
ENTIRE SYSTEM AND NOT THE PERIPHERY WHERE WINDS WOULD BE STRONGER.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
DURING THE SHORT TERM PERIOD...THE CLOSED UPPER LOW WILL DRIFT FROM
A POSITION NEAR BUFFALO SUNDAY EARLY EVENING TO THE BINGHAMTON AREA
DURING THE COURSE OF SUNDAY NIGHT...BEFORE MOVING ON TO NEW ENGLAND
ON MONDAY AND THE EVENTUALLY MAINE COAST MONDAY NIGHT.

WITH THE LOSS OF DAYTIME HEATING SUNDAY NIGHT...EXPECT THAT SUNDAY
AFTERNOONS WIDESPREAD DIURNALLY-DRIVEN CONVECTION WILL GRADUALLY
WEAKEN AND BECOME MORE SCATTERED WITH TIME...THOUGH IT WILL LIKELY
NOT SHUT OFF COMPLETELY WITH THE CORE OF THE UPPER LOW AND
ASSOCIATED COLD POOL SLOWLY WORKING ACROSS THE AREA. AT THIS
POINT...HAVE ELECTED TO KEEP THINGS SIMPLE IN THE FORECAST WITH
BROADBRUSH LIKELY POPS EARLY IN THE EVENING...GRADUALLY TAPERING
DOWN TO THE CHANCE/SCATTERED RANGE DURING THE REMAINDER OF THE
NIGHT. WHILE THERE IS AT LEAST SOME POTENTIAL FOR SOME LAKE
ENHANCEMENT TO SET UP BEHIND THE LOW LATER SUNDAY NIGHT...THERE
REMAINS CONSIDERABLE UNCERTAINTY WITH RESPECT TO THE EXACT TRACK OF
THE LOW...AND EXACTLY HOW THE LOW LEVEL WIND FIELDS WILL EVOLVE
BEHIND ITS PASSAGE. WITH AT LEAST SOME DOUBT IN MY MIND AS TO
WHETHER A SUFFICIENTLY ALIGNED FLOW TO SUPPORT LAKE EFFECT WILL
DEVELOP...HAVE OPTED TO NOT INDICATE ANY AREAS OF LAKE ENHANCEMENT
IN THE FORECAST AT THIS TIME.

DURING MONDAY...WILL LEAVE A CHANCE OF CONVECTION IN THE FORECAST AS
MOISTURE CONTINUES TO WRAP AROUND THE SLOW MOVING CLOSED LOW...WITH
THE HIGHEST POPS FOUND ACROSS THE NORTH COUNTRY...WHICH WILL BE
SUBJECT TO ANOTHER VORTICITY LOBE WRAPPING AROUND THE BACK SIDE OF
THE LOW CENTER.

AS THE UPPER LOW PULLS FURTHER AWAY FROM OUR REGION MONDAY
NIGHT...WILL FINALLY DROP POPS BELOW THE CHANCE THRESHOLD FROM
SOUTHWEST TO NORTHEAST AS FORCING WEAKENS...AND LOW LEVEL
RIDGING/DRIER AIR BEGINS BUILDING IN FROM THE CENTRAL GREAT LAKES.

TEMPERATURES THROUGH THE PERIOD WILL REMAIN BELOW NORMAL DUE TO THE
INFLUENCE OF THE UPPER LOW AND COLD POOL...WITH 850 MB TEMPS OF +9C
OR SO ONLY SUPPORTING HIGHS IN THE LOWER 70S ON MONDAY.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
IN GENERAL...THE EXTENDED PORTION OF THE FORECAST WILL CONTINUE TO
FEATURE LARGE-SCALE UPPER RIDGING ACROSS THE WESTERN PART OF NORTH
AMERICA...WITH A DOWNSTREAM TROUGH REMAINING IN PLACE ACROSS THE
EAST. AS A RESULT...WE SHOULD CONTINUE TO SEE TEMPERATURES AVERAGING
A BIT BELOW NORMAL DURING THIS PERIOD...ALONG WITH PERIODIC CHANCES
FOR CONVECTION.

IN TERMS OF PRECIPITATION CHANCES...EXPECT DRY CONDITIONS ON TUESDAY
AS HIGH PRESSURE RIDGES IN FROM THE CENTRAL GREAT LAKES. THIS WILL
THEN BE FOLLOWED BY A RENEWED THREAT OF MORE SHOWERS AND
THUNDERSTORMS WEDNESDAY THROUGH FRIDAY AS ANOTHER CLOSED UPPER LEVEL
LOW DIGS SOUTHEAST ACROSS THE GREAT LAKES AND NORTHEAST. THE BEST
CHANCES FOR PRECIPITATION NOW APPEAR TO BE ON THURSDAY AND
FRIDAY...WHEN THE CORE OF THIS SYSTEM IS EXPECTED TO PASS ACROSS THE
FORECAST AREA. THIS SHOULD FOLLOWED BY A RETURN TO DRIER WEATHER ON
SATURDAY AS THE LOW PULLS OUT ACROSS NEW ENGLAND...AND SURFACE BASED
RIDGING BUILDS EAST ACROSS THE GREAT LAKES IN ITS WAKE.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
A SEVERE WEATHER THREAT WILL REMAIN IN PLACE FROM ROC WEST TO LAKE
ERIE THIS EVENING.

AN ANOMALOUSLY DEEP UPPER LEVEL STORM SYSTEM DROPPING SOUTHEAST FROM
LAKE HURON WILL CIRCULATE WIDESPREAD SHRA/TSRA ACROSS WESTERN NEW
YORK TONIGHT...WITH SOME OF THE STORMS POSSIBLY CONTAINING SOME HAIL
AND WIND GUSTS TO 40 MPH. ALONG WITH THE RISK OF STRONG TO SEVERE
WEATHER...CIGS/VSBYS WILL DROP TO MVFR LEVELS WITH OCCASIONAL IFR
CIGS POSISBLE LATE. AS A RESULT...THE CURRENT VFR CONDITINOS ARE
EXPECTED TO DETERIORATE AS THE NIGHT PROGRESSES. THIS WILL BE THE
CASE FOR ALL OF THE WRN NEW YORK TAFS...WITH THE EXCEPTION OF KART
WHICH WILL LIEKLY REMAIN VFR UNTIL AFTER DAYBREAK SUNDAY.

THE STORMS WILL BE FAIRLY SLOW MOVING...SO THEY WILL HAVE A GREATER
CHANCE OF IMPACTING AIRPORT OPERATIONS AND THUS PROMOTING DELAYS.

FOR SUNDAY...THE DEEP UPPER LEVEL STORM WILL DROP DIRECTLY ACROSS
THE FAR WESTERN COUNTIES. THIS WILL RESULT IN AN INCREASING RISK OF
SHRA/TSRA DURING THE COURSE OF THE DAY. DESPITE THIS...MOST SITES
WILL EXPERIENCE VFR CONDITIONS ON SUNDAY...ALTHOUGH THE CHANCE FOR A
COUPLE HOURS OF MVFR CIGS WILL BE POSSIBLE. THE HIGHEST CHANCE FOR
MVFR CIGS SUNDAY WILL BE FOUND EAST OF LK ONTARIO WHERE THE RISK OF
SHRA/TSRA WILL BE GREATEST.

OUTLOOK...
MONDAY...VFR/LOCALLY MVFR IN SCATTERED SHOWERS/THUNDERSTORMS.
TUESDAY THROUGH THURSDAY...GENERALLY VFR.

&&

.MARINE...
MODERATE SOUTHWEST WINDS WILL BECOME LOCALLY GUSTY IN THUNDERSTORMS
AS THEY CROSS THE REGION TONIGHT...THEN WILL BECOME LIGHT ON SUNDAY
AS LOW PRESSURE PASSES SOUTHEAST ACROSS WESTERN LAKE ONTARIO INTO
WESTERN NEW YORK. WINDS WILL TEND SOUTHWEST AND WEST ON THE LAKE
ERIE AND WESTERN LAKE ONTARIO WATERS...BUT BE VARIABLE OR BACK TO
EASTERLY OVER EASTERN LAKE ONTARIO DURING SUNDAY. AS THE LOW CROSSES
THE AREA SUNDAY NIGHT AND MONDAY...GENERALLY LIGHT WINDS WILL
FRESHEN AND TEND NORTHWESTERLY IN ITS WAKE...THOUGH WINDS AND WAVES
ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA AT THIS
TIME.

WATERSPOUTS WILL ALSO BECOME A DISTINCT POSSIBILITY ONCE AGAIN LATER
TONIGHT AND SUNDAY AS A COLD POOL ALOFT OVERSPREADS THE AREA...AND
WILL LIKELY REMAIN SO THROUGH SUNDAY NIGHT AND MONDAY MORNING.
