WITH 850 MB TEMPERATURES OFF 12Z KBUF SOUNDING AT -14C...WITH 850
MB AIR FORECAST TO DROP TO NEAR -16C BY 00Z THIS EVENING. BASED
ON OVERNIGHT AND MORNING AMOUNTS ACROSS THE HIGHER SPOTS OVER
CHAUTAUQUA AND CATTARAUGUS COUNTIES OF 2-4 INCHES...AND WITH
ADDITIONAL LOCAL AMOUNTS OF 4-8 INCHES EXPECTED THIS AFTERNOON
AND TONIGHT WILL ISSUE A LAKE EFFECT SNOW WARNING FOR THOSE TWO
COUNTIES. LAKE EFFECT PARAMETERS BECOMING INCREASINGLY FAVORABLE
TONIGHT THROUGH FRIDAY NIGHT ACROSS THE TUG HILL AS WESTERLY FLOW
BECOMES BETTER ALIGNED...WITH THEREFORE GO AHEAD AND ISSUE A LAKE
EFFECT SNOW WARNING THERE AS WELL WITH THIS UPDATE PACKAGE.

.PREV DISCUSSION...
/ISSUED 739 AM EDT THU APR 5 2007/

AVIATION /12Z-12Z/...

LOW PRESSURE CENTERED OVER SOUTHWEST QUEBEC WILL DRIFT SLOWLY TO THE
EAST AND WEAKEN TODAY WHILE A SECOND LOW LIFTS NORTH UP THE NEW
ENGLAND COAST. COLD AIR CIRCULATING AROUND THESE LOWS WILL MAKE THE
ATMOSPHERE UNSTABLE ENOUGH TO GENERATE SNOW SHOWERS THROUGHOUT THE
FORECAST PERIOD. EXPECT MAINLY MVFR CONDITIONS WITH THE SNOW
SHOWERS...BUT THE VISIBILITY WILL LOWER TO IFR AT TIMES IN
OCCASIONAL BURSTS OF STEADIER SNOW...ESPECIALLY ACROSS THE HIGHER
ELEVATIONS EAST OF THE LAKES.

PREV DISCUSSION...
/ISSUED 300 AM EDT THU APR 5 2007/

SHORT TERM /TODAY THROUGH SATURDAY/...

AN UPPER LOW WILL KEEP COLD AIR OVER THE AREA THROUGH SATURDAY.
SHORT WAVES AS SEEN IN THE SPOKES OF VORTICITY WILL MIGRATE
THROUGH THE LOW BRINGING SNOW SHOWERS FROM TIME. 850 MB
TEMPERATURES OF -14 WILL BE COLD ENOUGH FOR LAKE ENHANCEMENT IN
OROGRAPHIC LIFT OFF LAKE ERIE...AND OVER THE TUG HILL WHERE WINDS
WILL LINE UP OFF LAKE ONTARIO TONIGHT THROUGH SATURDAY.
ACCUMULATIONS OFF LAKE ERIE WILL BE LIMITED DUE TO THE ICE COVER.
THERE IS ALSO A QUESTION ABOUT HOW MUCH THE LAKE SNOWS WILL BE
DISRUPTED BY THE STRONG APRIL DIURNAL HEATING WHICH WOULD NOT BE A
FACTOR IN THIS PATTERN IN THE MID WINTER. EAST OF LAKE ONTARIO THE
NAM QPF HAS VALUES BELOW LAKE SNOW WARNING CRITERIA, BUT THEY
ARE SOMETIMES TOO LOW, SO WE HAVE RAISED THEM ENOUGH TO KEEP THE
LAKE SNOW WATCH GOING FOR TONIGHT. THE DAY SHIFT WILL NEED TO
DECIDE ON AN ADVISORY OR WARNING AFTER LOOKING AT THE NEXT RUN.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...

THE LARGE CLOSED UPPER LOW WILL PERSIST ACROSS SOUTHEASTERN CANADA
AND THE NORTHEAST UNITED STATES THROUGH EASTER SUNDAY. TEMPERATURES
WILL BE WELL BELOW THROUGH THEN WITH AREAS OF LAKE EFFECT
PRECIPITATION COMMON PLACE SOUTHEAST OF THE LAKES AND AT LEAST
SCATTERED ACTIVITY IN THE CYCLONIC FLOW.

THE LOW FINALLY BEGINS TO WITHDRAW NORTHEAST SUNDAY NIGHT BUT
ANOTHER DIGGING TROUGH OVER THE UPPER LAKES REGION WILL KEEP
TEMPERATURES BELOW NORMAL THROUGH AT LEAST MONDAY NIGHT.
SLIGHTLY MILDER TUESDAY AND WEDNESDAY BUT A SYSTEM FORECAST TO
DEVELOP OVER THE OHIO VALLEY AND MOVE EAST WILL LEAD TO A THREAT OF
A COLD RAIN WEDNESDAY. THIS WOULD KEEP HIGHS IN THE 40S. WE WILL GO
WITH HPC VALUES AT THIS TIME WHICH ARE HIGHER BUT LOOK FOR POSSIBLE
CHANGES IN UPCOMING FORECASTS.

MARINE...

DEEP LOW PRESSURE CENTERED NORTH OF GEORGIAN BAY WILL CONTINUE TO
CIRCULATE MUCH COLDER AIR ACROSS THE LOWER LAKES REGION FOR THE NEXT
FEW DAYS AT IT MOVES SLOWLY EAST. THE COLDER AIR POURING ACROSS THE
LAKES WILL PRODUCE ENOUGH INSTABILITY FOR WINDS TO MIX DOWN FROM
ALOFT. SMALL CRAFT ADVISORIES REMAIN IN EFFECT THROUGH FRIDAY FOR
THE SOUTH SHORES OF LAKE ONTARIO.

WEDNESDAYS BRISK SOUTHWEST WINDS FORCED THE ICE ON LAKE ERIE BACK
INTO THE EASTERN END OF THE LAKE.  THEREFORE...THE SMALL CRAFT
ADVISORY FOR THE EASTERN END OF LAKE ERIE HAS BEEN CANCELED.

SNOW SHOWERS WILL CONTINUE MOVING OVER THE REGION THIS MORNING.
BRIEF HEAVY SNOW SHOWERS COMBINED WITH STRONG WINDS CAN PRODUCE NEAR
WHITEOUT CONDITIONS, ESPECIALLY OVER THE SOUTHERN TIER. POOR
VISIBILITIES ALONG WITH SLICK ROAD CONDITIONS CAN MAKE TRAVEL VERY
HAZARDOUS. ALLOW EXTRA TIME AND SLOW DOWN FOR YOUR MORNING COMMUTE.
