AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
836 AM EDT SAT APR 11 2009

.SYNOPSIS...
HIGH PRESSURE BUILDING ACROSS THE GREAT LAKES WILL BRING DRY BUT
CHILLY WEATHER FOR THE WEEKEND EXCEPT FOR A CHANCE OF SOME
FLURRIES SOUTH OF LAKE ONTARIO ACROSS THE FINGER LAKES REGION LATE
TONIGHT. TEMPERATURES WILL SLOWLY MODERATE TO MORE SEASONABLE LEVELS
MONDAY AND TO ABOVE NORMAL LEVELS TUESDAY WITH HIGH PRESSURE KEEPING
DRY AIR OVER THE REGION.

&&

.NEAR TERM /THROUGH TONIGHT/...
LOW PRESSURE WILL MOVE OFF THE EAST COAST TODAY WHILE HIGH PRESSURE
BUILDS SOUTHEAST FROM THE UPPER GREAT LAKES. FAIR AND DRY CONDITIONS
WILL PREVAIL TODAY, BUT A COOL NORTHERLY FLOW AHEAD OF THE HIGH WILL
KEEP HIGH TEMPERATURES ABOUT 5 DEGREES BELOW NORMAL. THE COLD AIR
WILL DEEPEN IN THE NORTHERLY FLOW TONIGHT WITH 850 MB TEMPERATURES
FALLING TO AROUND -12C. A CAP AROUND 5K FEET WILL LIMIT CONVECTION,
BUT IT WILL BE COLD ENOUGH FOR INCREASED CLOUD COVER AND SOME LAKE
GENERATED FLURRIES SOUTH OF LAKE ONTARIO.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
DRY AND CHILLY CONDITIONS WILL CHARACTERIZE THE WEATHER THROUGH MUCH
OF THIS TIME PERIOD. A DEEP UPPER LEVEL TROUGH IS EXPECTED TO TRACK
SOUTHEAST ACROSS THE NEW ENGLAND STATES EASTER SUNDAY AND SUNDAY
EVENING.

THE SURFACE LOW THAT IS ASSOCIATED WITH THE UPPER TROUGH WILL HEAD
NORTHEAST TOWARD THE CANADIAN MARITIMES SUNDAY...WHILE COOL HIGH
PRESSURE BUILDS SOUTHEAST ACROSS THE GREAT LAKES. THE PRESSURE
GRADIENT BETWEEN THE DEPARTING LOW AND GREAT LAKES HIGH WILL BE
ENOUGH TO CREATE A RATHER CHILLY BREEZE ON SUNDAY. TEMPERATURES WILL
STRUGGLE TO REACH THE LOW TO MID 40S WITH 850 MB TEMPERATURES
FORECAST TO AVERAGE AROUND -10 TO -12C EARLY IN THE AFTERNOON.

AS THE HIGH BUILDS ACROSS NEW YORK STATE SUNDAY NIGHT...THE WINDS
WILL SUBSIDE. THE PRESENCE OF VERY DRY AIR (DEWPOINTS RANGING
THROUGH THE TEENS) WITH MAINLY CLEAR SKIES WILL ALLOW TEMPERATURES
TO DROP TO 20 TO 25 ACROSS MUCH OF WESTERN NEW YORK WITH TEENS
ACROSS INTERIOR SECTIONS OF THE SOUTHERN TIER AND EAST OF LAKE
ONTARIO.

THE SURFACE HIGH IS FORECAST TO RIDGE SOUTH INTO THE MIDDLE ATLANTIC
STATES MONDAY. WARM AIR ADVECTION ALOFT WILL BE ACCOMPANIED
BY A CORRESPONDING INCREASE IN SURFACE TEMPERATURES THAT SHOULD
REBOUND TO AROUND NORMAL LEVELS MONDAY AFTERNOON AFTER A CHILLY
MONDAY MORNING. HIGHS SHOULD RANGE FROM 50 TO 55 ACROSS MUCH OF THE
REGION FROM THE FINGER LAKES WEST TO UPPER 40S ACROSS THE NORTH
COUNTRY.

MONDAY NIGHT WILL FEATURE A GRADUAL INCREASE IN UPPER LEVEL CLOUDS
AND MILDER OVERNIGHT TEMPERATURES AS WARM AIR ADVECTION CONTINUES
AHEAD OF AN APPROACHING MIDWEST LOW. LOWS MONDAY NIGHT SHOULD ONLY
DROP TO THE MID 30S ACROSS WESTERN AREAS...LOWER 30S ACROSS THE
FINGER LAKES AND MID TO UPPER 20S EAST OF LAKE ONTARIO.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
A TRANSITION TO ABOVE NORMAL TEMPERATURES IS EXPECTED DURING THIS
FORECAST PERIOD AS THE RIDGE OF AN OMEGA BLOCK IS FORECAST TO EDGE
EAST ACROSS THE GREAT LAKES AND OHIO VALLEY.

WILL CUT BACK ON THE CHANCE OF RAIN ON TUESDAY TO AREAS JUST ACROSS
THE SOUTHERN TIER, AS THE LATEST GFS AND ECMWF KEEP THE RAIN MORE TO
OUR SOUTH, AND THEN JUST BRING IT UP TO AROUND BUFFALO TUESDAY
NIGHT. AREAS FURTHER TO THE EAST AND NORTH SHOULD REMAIN DRY. EXPECT
DRY CONDITIONS WEDNESDAY AS THE LOW SLIDES OFF THE MIDDLE ATLANTIC
COAST. HIGH PRESSURE RIDGING SOUTH FROM ONTARIO PROVINCE SHOULD
BRING MORE DRY WEATHER THURSDAY. THE LATEST GFS 500MB ENSEMBLE MEAN
SUGGESTS THAT THE RIDGE WILL REMAIN INTACT LONG ENOUGH TO KEEP
THINGS DRY THROUGH FRIDAY.

AREA TEMPERATURES ARE EXPECTED TO WARM INTO THE MID AND UPPER 50S
WEDNESDAY THROUGH FRIDAY...WITH LOWER 60S POSSIBLE ACROSS PARTS OF
THE GENESEE VALLEY.

&&

.AVIATION /13Z SATURDAY THROUGH WEDNESDAY/...
LOW PRESSURE WILL MOVE EAST OFF THE MARYLAND COAST THIS WHILE HIGH
PRESSURE BUILDS IN FROM THE UPPER LAKES. CLOUDS ARE THINNING AND
SKIES SHOULD CLEAR THIS MORNING WITH UNLIMITED VFR CONDITIONS
CONTINUING.

COLD AIR MOVING IN FROM THE NORTH WILL GENERATE CLOUDS AND
AND FLURRIES SOUTH OF LAKE ONTARIO TONIGHT. THERE MAY BE
OCCASIONAL MVFR CONDITIONS AT ROCHESTER OVERNIGHT OTHERWISE VFR
WILL PREVAIL.

SUNDAY...VFR.
MONDAY...VFR.
TUESDAY...GENERALLY VFR...BUT MVFR IN SCATTERED SHOWERS.
WEDNESDAY...VFR.

&&

.MARINE...

SMALL CRAFT ADVISORIES HAVE BEEN ISSUED FOR THE SOUTH SHORE OF LK
ONTARIO AS NORTHERLY WINDS OF 15 TO 20 KTS ARE ALREADY PRODUCING
AT LEAST 4 FT WAVES AS OF 12Z. THESE WINDS WILL HOLD THROUGH MIDDAY
THEN DIMINISH SOME THIS AFTERNOON BEFORE PICKING UP AGAIN LATER
TONIGHT. WILL HAVE ADVISORY UNTIL 3 PM AND REVISIT LATER. LOW
PRESSURE SLIDING OFF THE VIRGINIA COAST AND HIGH PRESSURE BUILDING
ACROSS THE GREAT LAKES WILL BRING A BRISK NORTHEAST TO NORTH FLOW
TODAY. COLDER AIR TONIGHT WILL BRING INCREASING NORTHWEST WINDS.
THE HIGH WILL THEN BUILD OVER THE LOWER LAKES AND PERSIST WITH
RELATIVELY LIGHT WINDS FROM SUNDAY NIGHT THROUGH FRIDAY.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
NY...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 3 PM EDT THIS AFTERNOON FOR LOZ042-
