AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
359 PM EDT WED JUN 27 2007

.SYNOPSIS...
A COLD FRONT IS FORECAST TO MOVE INTO WESTERN NEW YORK LATE TONIGHT
BRINGING WITH IT A HIGHER THREAT OF SHOWERS AND STORMS. THE SHOWERS
SHOULD END ACROSS NORTHERN AREAS EARLY THURSDAY WITH THE THREAT OF
SHOWERS LOWERING FROM NORTHWEST TO SOUTHEAST DURING THE DAY AS THE
FRONT MOVES SOUTHEAST OF THE AREA. A FEW DAYS OF PLEASANTLY COOL AND
DRY WEATHER IS THEN EXPECTED FRIDAY INTO THE WEEKEND ALTHOUGH THERE
IS A CHANCE OF A SHOWER SATURDAY EAST OF LAKE ONTARIO.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
COLD FRONT APPROACHES AND CROSSES AREA AFTER MIDNIGHT...REACHING SRN
TIER BY DAYBREAK. AREA ESPCLY WEST OF THE GENESEE VALLEY SHLD GET
DECENT SHOT OF RAIN FROM TSTM COMPLEX CURRENTLY MOVING INTO SW
ONTARIO PROVINCE. ANY TSTM COULD GET LOCALLY HVY DOWNPOUR. LKLY POPS
FOR SHWRS/TSTMS LOOKS GOOD FOR THE AREA. SEVERE TSTM WATCH CONTINUES
UNTIL 8 PM FOR CAYUGA COUNTY.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
THURSDAY, MAIN COLD FRNT MOVES SE OF BUF/IAG/ART EARLY IN THE
MORNING. WILL KEEP LKLY POPS WITH TSTMS ACROSS THE SOUTHERN TIER IN
THE MORNING WITH CHC OF SHWRS BETWEEN SOUTHERN TIER AND BUF/ROC AREA
WITH NO MENTION OF SHWRS NORTH COUNTRY. THREAT OF SHWRS WILL DROP TO
CHANCE RANGE ONLY ACROSS THE SOUTHERN TIER IN THE AFTERNOON WITH
SOME CLRING DURG THE AFTERNOON NORTH OF THE SOUTHERN TIER. TEMPS
BEHIND FRONT WILL DROP TO THE 70S.

THURSDAY NIGHT, COLD FRNT WELL SOOUTH AND EAST OF THE AREA BUT THERE
WILL BE LINGERING CLOUDS IN THE EVENING ACROSS THE SOUTHERN TIER.
DRIER AND COOLER AIR WILL WORK SOUTH AND EAST ACROSS THE AREA AS
HIGH PRESSURE BEGINS TO BUILD EAST FROM THE WESTERN LAKES.

FRIDAY, STILL LOOKS NICE AS A RIDGE OF HIGH PRESSURE BUILDS EAST
FROM THE WESTERN LKS WITH TEMPS GENLY IN THE 70S WITH LOW HUMIDITY.
LATE FRIDAY NIGHT A WEAK TROUGH IS EXPECTED TO DROP SOUTH TWD THE ST
LAW VALLEY. PUT CHC OF A SHWR IN GRIDS ACROSS ST LAW AREA FOR MARINE
INTERESTS.

SATURDAY, UPPER TROUGH VCNTY OF THE ST LAW VALLEY WILL BRING A
CHANCE OF SHWRS TO PORTIONS OF EASTERN LAKE ONTARIO REGION.
ELSEWHERE EXPECT PTLY-MSTLY SUNNY SKIES WITH MOST SUN ALNG SOUTHERN
TIER. TEMPS SOME 8-9 DEGREES BELOW NORMAL, VCNTY OF 70.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
THE REGION WILL BE UNDER THE INFLUENCE OF A COOL UPPER TROUGH ALOFT
ACROSS THE NORTHEASTERN STATES AND COOL SURFACE HIGH PRESSURE
CENTERED OVER THE CENTRAL GREAT LAKES AND MID WEST. TEMPERATURES
WILL RANGE ABOUT 8 TO 10 DEGREES BELOW NORMAL THROUGH THE WEEKEND
(NEAR 70). THE HIGH PRESSURE CENTER WILL BUILD FARTHER TO THE EAST
ON SUNDAY AS THE UPPER TROUGH SLIDES A BIT MORE TO THE EAST. ONLY
AFTER THE HIGH CENTER MOVES EAST OF THE REGION ON MONDAY AND TUESDAY
WILL A WARMING TREND RETURN WITH AFTERNOON HIGH BACK CLOSER TO THE
UPPER 70S TO LOW 80S...CLOSE TO SEASONAL NORMALS. WITH THE WARMER
TEMPERATURES WILL COME ANOTHER CHANCE OF RAIN TUESDAY NIGHT AND
WEDNESDAY. GFS TAKES A LOW PRESSURE CENTER SOUTH OF THE REGION...BUT
THIS TRACK IS STILL RATHER UNCERTAIN. A TRACK NORTH OF THE REGION
WILL BRING MORE WARM AIR AND CONTINUE THE MID WEEK WARMING TREND.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
DIURNAL HEATING AND INCREASING INSTABILITY HAVE SET OFF SOME
SCATTERED THUNDERSTORMS...PARTICULARLY ACROSS INTERIOR SECTIONS
AWAY FROM ANY LAKE INFLUENCES THIS AFTERNOON. GIVEN THE AMOUNT OF
ATMOSPHERIC MOISTURE THAT WILL BE AVAILABLE...THERE WILL BE THE
POTENTIAL FOR ANY STORM TO PRODUCE IFR VSBYS IN HEAVY RAIN...BUT THE
CELLS WILL MOSTLY MISS THE TAF LOCATIONS.

A COLD FRONT LOCATED OVER THE UPPER MIDWEST WILL DROP SOUTH ACROSS
THE AREA THIS EVENING THROUGH THURSDAY MORNING. THIS FRONT WILL
BRING A HIGHER LIKELIHOOD OF SHOWERS AND THUNDERSTORMS ALONG WITH A
RISK OF LOWER CIGS AND VSBYS. AFTER THE FRONT PASSES THROUGH THE
AREA BY MID DAY THURSDAY...DRIER AND COOLER WEATHER WILL RETURN WITH
VFR CONDITIONS EXPECTED TO LAST INTO THE WEEKEND.

&&

.MARINE...
PREFRONTAL WINDS UP THE FULL LENGTH OF LAKE ERIE WARRANT CONTINUING
SMALL CRAFT ADVISORY FOR BUFFALO HARBOR AND UPPER NIAGARA RIVER.
WINDS WILL DIMINISH AFTER 01Z...BUT WILL BE REPLACED BY LIKELIHOOD
OF STRONG THUNDERSTORMS BETWEEN 01Z AND 04Z (9PM TO MIDNIGHT).
SHOWERS AND THUNDERSTORMS WILL COME TO AN END BY EARLY THURSDAY
MORNING WITH THE PASSAGE OF THE COLD FRONT. WINDS WILL SWITCH TO
NORTHWEST THURSDAY EVENING AND REMAIN SO FOR FRIDAY AND
SATURDAY...VARYING FROM NORTHWEST TO NORTHEAST AT TIMES. LIGHTER AND
VARIABLE WINDS WILL ACCOMPANY HIGH PRESSURE ON SUNDAY.

&&

.HYDROLOGY...
OUR PARCHED REGION LOOKS TO GET SOME LIMITED RELIEF DURING THE
NEXT 24 HOURS OR SO. SCATTERED STORMS COULD DROP LOCALLY HEAVY
AMOUNTS THIS AFTERNOON INTO EARLY EVENING...BUT THEY WILL BE SPOTTY
AND AWAY FROM THE LAKES. MORE GENERAL QPF TONIGHT SHOULD AVERAGE
0.25 TO 0.5 INCH WITH A FEW SPOTS HIGHER. WE THEN LOOK TO BE DRY
FOR THE NEXT SEVERAL DAYS.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
NY...NONE.
