AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
344 PM EDT SAT AUG 22 2009

.SYNOPSIS...
A WEAK COLD FRONT WILL CONTINUE ACROSS THE REGION THIS EVENING AND
THEN STALL OVER EASTERN NEW YORK. AN UPPER LEVEL LOW WILL REMAIN
ACROSS THE LOWER LAKES THROUGH SUNDAY AND BRING THE RISK OF A FEW
SHOWERS. HIGH PRESSURE WILL THEN BUILD IN EARLY NEXT WEEK FOR DRY
AND WARMER WEATHER FROM MONDAY INTO WEDNESDAY BEFORE ANOTHER COLD
CROSSES WEDNESDAY AND WEDNESDAY NIGHT. MUCH COOLER AIR WILL FOLLOW
THIS FRONT TO END THE WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
THE MAIN WEATHER FACTOR DURING THIS NEAR TERM PERIOD WILL BE AN
UPPER LEVEL TROUGH AXIS EXTENDING FROM NEAR LAKE HURON TO THE OHIO
VALLEY AS OF MID AFTERNOON. THIS FEATURE HAS ALREADY PRODUCED
SCATTERED SHOWERS AND THUNDERSTORMS ACROSS MAINLY THE WESTERN END OF
NEW YORK STATE AND NEARBY SOUTHERN ONTARIO DURING THE AFTERNOON. WE
EXPECT THAT THERE WILL BE A DECREASE IN ACTIVITY AFTER DARK WITH THE
LOSS OF DIURNAL HEATING. WE WILL CARRY CHANCE POPS THROUGH THE
NIGHT...LIKELY FOR AWHILE FOR THE FAR EASTERN ZONES AS AN IMPULSE
EAST OF THE ABOVE MENTION TROUGH RIDES NORTHWARD UP THE SPINE OF THE
APPALACHIANS.

DURING THE DAY SUNDAY WE WILL HAVE SCATTERED CONVECTION ONCE AGAIN
AS THE UPPER TROUGH CONTINUES TO SETTLE ACROSS OUR REGION. IT WIL
PROBABLY BE JUST SHOWERS BUT THUNDER CANNOT BE TOTALLY RULED OUT.
WITH A COLD POOL ALOFT WE ALSO HAD TO MENTION A CHANCE OF
WATERSPOUTS ACROSS LAKE ERIE.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
THE UPPER LEVEL TROUGH WILL LIFT OUT TO THE COAST SUNDAY NIGHT AS
HIGH PRESSURE BEGINS TO RIDGE ACROSS THE LOWER GREAT LAKES. THE
RIDGE WILL DOMINATE OUR WEATHER THROUGH TUESDAY NIGHT WITH DRY
CONDITIONS. TEMPERATURES WILL REBOUND TO THE SEASONABLE UPPER 70S ON
MONDAY AND A FEW DEGREES WARMER ON TUESDAY.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
AS HIGH PRESSURE MOVES OFF THE ATLANTIC COAST ON WEDNESDAY A COLD
FRONT WILL APPROACH FROM THE UPPER GREAT LAKES AND BRING THE THREAT
OF SHOWERS/TSTMS DURING WEDNESDAY AND WEDNESDAY NIGHT.

COOLER AIR WILL FOLLOW THE FRONT THURSDAY...WITH H85 TEMPS COOLING
TO BETWEEN 6 AND 10C. A NORTHEAST BREEZE CIRCULATING OUT OF A
SOUTHERN ONTARIO HIGH WILL KEEP TEMPERATURES IN THE LOWER 70S
THURSDAY IN SPITE OF AN ANTICIPATED INCREASE IN SUNSHINE. EXPECT
MORE SUNSHINE ON FRIDAY...BUT THE COOL NORTHEAST WILL PREVAIL.

IN TERMS OF NIGHTTIME TEMPERATURES...THURSDAY NIGHT WILL LIKELY BE
THE COOLEST OF THE SEASON SO FAR WITH MOST INLAND AREAS DIPPING INTO
THE 40S.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
VFR CONDITIONS WILL BE THE RULE THE REST OF THE DAYLIGHT HOURS BUT
FIRING CONVECTION WILL REDUCE CONDITIONS TO MVFR AND IFR IN
SHOWERS AND THUNDERSTORMS. CONVECTION WILL GENERALLY END A COUPLE
OF HOURS AFTER DARK. LIGHT WINDS AND LOW LEVEL MOISTURE IS
EXPECTED TO LEAD TO IFR CIGS AFTER FROM 09Z-12Z AFTER WHICH VFR
WILL BE THE RULE AGAIN.

OUTLOOK... SUNDAY AFTERNOON...MAINLY VFR WITH CHC SHRA.
MONDAY AND TUESDAY...VFR.
WEDNESDAY AND THURSDAY...VFR WITH SCATTERED SHRA/TSRA.

&&

.MARINE...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BRING GUSTY
WINDS THROUGH THIS EVENING. CONDITIONS BECOME FAVORABLE FOR POSSIBLE
WATERSPOUTS LATE TONIGHT AND SUNDAY ON THE LAKE ERIE NEARSHORES.

A RIDGE OF HIGH PRESSURE WITH GENERALLY LIGHT WINDS WILL BUILD
ACROSS THE LAKES THROUGH THE FIRST HALF OF THE WEEK. AN APPROACHING
COLD FRONT WILL RESULT IN FRESHENING SOUTHWEST WINDS TUESDAY NIGHT
AND WEDNESDAY.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
