MUCH OF THE AREA LATE TONIGHT THROUGH SUNDAY. A FEW SCATTERED SNOW
SHOWERS WILL DEVELOP AS COLD AIR RUSHES BACK INTO THE AREA SUNDAY
WITH MORE ORGANIZED LAKE EFFECT SNOW EAST OF THE LAKES. THE COLDEST
AIR OF THE WINTER SEASON WILL THEN SETTLE IN FOR MUCH OF NEXT WEEK
WITH PERIODIC SNOW SHOWERS AND LAKE EFFECT SNOW EAST AND SOUTHEAST
OF THE LAKES.

&&

.NEAR TERM /THROUGH SUNDAY/...
SATELLITE IMAGERY THIS AFTERNOON SHOWING MOSTLY CLOUDY SKIES ACROSS
THE REGION AS MAINLY MID LEVEL CLOUD CONTINUES TO STREAM EAST ALONG
A STALLED OUT BAROCLINIC ZONE DRAPED FROM THE CENTRAL GREAT LAKES TO
THE OTTAWA VALLEY. THIS WILL CONTINUE TO BE THE CASE THROUGH THIS
EVENING WITH A FEW BREAKS IN THE CLOUDS NEAR THE PA STATE LINE AND
INTO THE FINGER LAKES. TEMPERATURES HAVE WARMED NICELY INTO THE
LOWER TO MID 40S IN MOST AREAS TODAY AS 850MB TEMPS APPROACH 0C WITH
STRONG MECHANICAL MIXING.

THOUGH THIS EVENING...BOTH THE NAM/GFS SUGGEST ANOTHER SURGE OF WARM
ADVECTION WILL CROSS THE REGION...ESPECIALLY FROM THE EAST END OF
LAKE ONTARIO INTO THE NORTH COUNTRY WHERE ISENTROPIC UPGLIDE WILL BE
MAXIMIZED. THIS WILL LIKELY PRODUCE A LITTLE LIGHT PRECIP. BOUNDARY
LAYER TEMPS WILL BE WARM ENOUGH CLOSE TO LAKE ONTARIO FOR MAINLY
RAIN...WITH A MIX OF RAIN AND SNOW FARTHER INLAND AND MAINLY SNOW
ACROSS THE HIGHEST TERRAIN. PRECIP AMOUNTS WILL BE LIGHT...SO DONT
EXPECT ANYTHING MORE THAN A LIGHT COATING AT THE HIGHEST ELEVATIONS.

LATER TONIGHT OUR FOCUS TURNS TO A STRONG MID LEVEL SHORTWAVE
APPROACHING WESTERN LAKE SUPERIOR THIS AFTERNOON. AN ASSOCIATED
SURFACE LOW WILL RAPIDLY DEEPEN AS IT TRACKS ACROSS THE UPPER LAKES
THIS EVENING AND INTO SOUTHERN QUEBEC BY EARLY SUNDAY MORNING...JUST
MAKING THE 24MB/24HOUR DEFINITION OF BOMBO-GENESIS. A STRONG COLD
FRONT TRAILING THIS LOW WILL ENTER WESTERN NY AROUND OR SHORTLY
AFTER 06Z SUN...AND REACH THE EASTERN LAKE ONTARIO REGION SHORTLY
AFTER 09Z SUN.

STRONG WINDS...THROUGH THIS EVENING...A LOW LEVEL JET WILL
STRENGTHEN AGAIN OVER THE REGION...BUT POOR LOW LEVEL LAPSE RATES
AND WARM ADVECTION WILL PREVENT MUCH OF THIS FROM MIXING DOWN.
FOLLOWING THE COLD FRONTAL PASSAGE...STRONG COLD AIR ADVECTION WILL
RAPIDLY STEEPEN LAPSE RATES AND PROVIDE DOWNWARD VERTICAL MOTION...
SETTING UP AN ENVIRONMENT SUPPORTIVE OF MIXING STRONG WINDS FROM
ALOFT DOWN TO THE SURFACE. ALSO...5-7MB PRESSURE RISES WILL PROVIDE
AN ISALLOBARIC BOOST TO THE WIND POTENTIAL. BUFKIT MOMENTUM TRANSFER
SCHEMES OFF THE 12Z GFS SUGGEST GUSTS TO 60MPH LATE TONIGHT INTO THE
FIRST HALF OF SUNDAY ACROSS MUCH OF THE AREA. FROM A CLIMATOLOGY
STANDPOINT...THIS IS A NEARLY CLASSIC SETUP WITH A RAPIDLY DEEPENING
SURFACE LOW PASSING JUST NORTH OF THE REGION WITH STRONG COLD AIR
ADVECTION AND STRONG WINDS ALOFT IN ITS WAKE. THE ONLY DIFFERENCE IN
THIS CASE IS THE WIND DIRECTION IS A LITTLE MORE WESTERLY THAN A
CLASSIC EVENT...AND THIS MAY HELP TO SPREAD THE STRONG GUSTS FARTHER
INLAND AWAY FROM THE LAKE PLAINS.

WITH ALL THIS IN MIND...WE HAVE ISSUED A HIGH WIND WARNING FOR THE
ENTIRE CWA FROM LATER TONIGHT THROUGH SUNDAY. WINDS OF THIS
MAGNITUDE WILL PRODUCE SCATTERED TREE DAMAGE AND POWER OUTAGES...AND
POSSIBLY SOME MINOR PROPERTY DAMAGE.

PRECIP...OVERNIGHT THERE WILL BE A BRIEF PERIOD OF LIGHT PRECIP
ALONG THE COLD FRONT ITSELF. THE BOUNDARY LAYER WILL BE QUITE MILD
AS THE FRONT APPROACHES...SO THIS MAY BE A MIX OF RAIN AND WET SNOW
OR EVEN ALL RAIN AT THE ONSET ACROSS LOWER ELEVATIONS. ANY RAIN WILL
QUICKLY CHANGE TO SNOW AS COLDER AIR FLOODS BACK INTO THE AREA IN
THE WAKE OF THE FRONT. GIVEN THE LACK OF MOISTURE ALONG THE FRONT
AND MARGINAL SURFACE TEMPERATURES AT FIRST...EXPECT LITTLE OR NO
ACCUMULATION OVERNIGHT AT LOWER ELEVATIONS...AND A COATING ACROSS
HIGHER TERRAIN.

ON SUNDAY...OUTSIDE OF LAKE EFFECT AREAS THERE WILL JUST BE A FEW
SCATTERED LIGHT SNOW SHOWERS WITH A SPOTTY DUSTING OF ACCUMULATION.
THE SNOW SHOWERS MAY BECOME A LITTLE MORE PERSISTENT ACROSS WESTERN
NY LATE IN THE DAY...BUT STILL ONLY EXPECT A DUSTING TO HALF INCH OR
SO.

OUR ATTENTION THEN TURNS TO LAKE EFFECT.

OFF LAKE ERIE...LAKE INDUCED EQUILIBRIUM LEVELS RISE TO AROUND 6K
FEET VERY LATE TONIGHT...THEN STAY THERE THROUGH SUNDAY. SOUTHWEST
FLOW IN THE WAKE OF THE COLD FRONT MAY BRIEFLY ALLOW THE FIRST LAKE
EFFECT TO SET-UP NEAR BUFFALO AND GENESEE COUNTY...BUT THIS WOULD BE
VERY...VERY BRIEF AS WINDS QUICKLY VEER WESTERLY BY MID MORNING...
FORCING LAKE EFFECT INTO THE TRADITIONAL SNOWBELTS OF SKI COUNTRY.
THE AIRMASS IS QUITE DRY...WHICH WILL GREATLY LIMIT INSTABILITY.
STRONG WINDS IN THE BOUNDARY LAYER WILL ALSO HURT ORGANIZATION WITH
ADDED SHEAR. WITH THIS IN MIND...ONLY EXPECT 1-2 INCHES IN
PERSISTENT BANDS THROUGH LATE SUNDAY AFTERNOON...MAINLY ACROSS THE
HIGHER TERRAIN OF SOUTHERN ERIE/WYOMING COUNTIES WELL SOUTH OF
BUFFALO AND INTO THE SOUTHERN TIER.

OFF LAKE ONTARIO...MOISTURE WILL BE A LITTLE DEEPER HERE...WHICH
WILL ALLOW LAKE INDUCED EQUILIBRIUM LEVELS TO RISE TO 8-9K FEET.
BOUNDARY LAYER WINDS WILL BE EVEN STRONGER HOWEVER...WHICH WILL
PROBABLY PREVENT A COHERENT SINGLE BAND FROM FORMING MOST OF THE DAY
DESPITE LONG WESTERLY FETCH. EXPECT A BAND TO DEVELOP NEAR WATERTOWN
AT DAYBREAK...THEN QUICKLY MOVE SOUTH TO THE TUG HILL REGION. MOST
AREAS WILL ONLY SEE 1-3 INCHES...BUT AN ADDED BOOST FROM UPSLOPE
FLOW ON THE TUG HILL MAY PRODUCE SOME LOCAL 3-4 INCH AMOUNTS THERE.
THIS IS MARGINAL...BUT GIVEN THE STRONG WINDS AND POTENTIAL FOR
BLOWING/DRIFTING SNOW...WILL GO WITH A LAKE EFFECT SNOW ADVISORY
MAINLY FOR THE TUG HILL REGION FOR SUNDAY. BY EARLY SUNDAY EVENING
LAKE EFFECT WILL HAVE MOVED SOUTH OF THE TUG HILL AND INTO OSWEGO/N
CAYUGA/WAYNE COUNTIES. SEE THE SHORT TERM SECTION BELOW FOR MORE
DETAILS ON THAT STAGE.

TEMPERATURES WILL REMAIN MILD THROUGH MOST OF TONIGHT...THEN BEGIN
TO FALL SHARPLY FOLLOWING THE COLD FRONTAL PASSAGE LATE.
TEMPERATURES ON SUNDAY WILL BE DECIDEDLY NON-DIURNAL...WITH
TEMPERATURES STEADILY FALLING THROUGH THE 20S...AND INTO THE TEENS
BY LATE IN THE DAY ACROSS THE HIGHER TERRAIN OF THE SOUTHERN TIER
AND EAST OF LAKE ONTARIO.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
SUNDAY NIGHT COLD AIR WILL CONTINUE TO BE POURING OVER THE
RELATIVELY WARM EASTERN GREAT LAKES AS A BLOCKING PATTERN ALLOWS
ARCTIC AIR TO BE DISLODGE SOUTHWARD FROM THE POLES TOWARDS SOUTHERN
CANADA. TEMPERATURES ALOFT AT 850 HPA WILL BE DROPPING THROUGH THE TEENS
SUNDAY NIGHT AND TOWARDS -20 TO -21C DURING THE DAY MONDAY. THIS
COLDER AIR OVER THE LAKES WILL CREATE MODERATE TO EXTREME LAKE
INSTABILITY...AND ALSO PRODUCE A TROUGH AND CONVERGENT BOUNDARY OVER
THE LAKES LATER SUNDAY NIGHT AND INTO MONDAY. SYNOPTIC MOISTURE
SUNDAY NIGHT AND MONDAY IS STILL RELATIVELY ABUNDANT...GIVEN THE
DEEPENING COLD AIR MASS AND SNOWFALL WILL BE LIGHT IN DENSITY.

OFF LAKE ONTARIO...FOR SUNDAY NIGHT EXPECT A LAKE EFFECT SNOW BAND
OFF LAKE ONTARIO ORIENTED ALONG THE SOUTHERN SHORELINE OF THE LAKE AND
INLAND ACROSS WAYNE...CAYUGA AND SOUTHERN OSWEGO COUNTY. BOTH THE
12Z NAM AND REGIONAL CANADIAN HAVE LOW LEVEL LIFT...WITH A NORTHWEST
FLOW FROM THE NORTHERN SIDE OF LAKE ONTARIO...WHILE ALONG THE
SOUTHERN SHORELINE A MORE WESTERLY TO SOUTHWESTERLY FLOW WILL BE IN
PLACE. THIS LOW LEVEL CONVERGENCE...COUPLED WITH MOISTURE THROUGH
THE BOUNDARY LAYER AND DECREASING AMOUNTS OF WIND SHEER SHOULD ALLOW
FOR A NICE SINGLE BAND OF LAKE EFFECT SNOW OFF LAKE ONTARIO. THE NAM
IS EVEN HINTING AT POSSIBLE UPSTREAM CONNECTS TO GEORGIAN BAY AND
LAKE HURON LATER SUNDAY NIGHT. WE WILL HOIST A LAKE EFFECT SNOW
ADVISORY THROUGH SUNDAY NIGHT FOR WAYNE...NORTHERN CAYUGA AND OSWEGO
COUNTIES. FOR NOW WE WILL LEAVE MONROE...AND ORLEANS COUNTIES OUT OF
THE ADVISORY...THOUGH A SUBTLE SOUTHWARD SHIFT TO THE LAKE BAND FROM
OVER LAKE ONTARIO MAY CHANGE FINAL SNOW TOTALS. WINDS WILL BE LIGHT
BY MONDAY MORNING SO THAT ANY FALLING LAKE EFFECT SNOW OFF LAKE
ONTARIO WILL PRIMARILY BE OVER THE LAKE AND ALONG THE IMMEDIATE LAKE
SHORELINE.

OFF LAKE ERIE...ALSO EXPECT LAKE EFFECT SNOW TO BE CONTINUING SUNDAY
NIGHT...THOUGH WITH WEAKER LOW LEVEL CONVERGENCE SNOWFALL RATES AND
TOTALS WILL LIKELY BE LOWER WHEN COMPARED TO LAKE ONTARIO. LAKE
INDUCED EQUILIBRIUM LEVELS SUNDAY NIGHT RISE TO AROUND 8K FEET OFF
LAKE ERIE.

ELSEWHERE A FEW SCATTERED SNOW SHOWERS MAY FALL SOUTH OF LAKE
ONTARIO...WHILE THE NORTH COUNTRY WILL LIKELY REMAIN DRY OVERNIGHT
WITH POSSIBLE PATCHY CLEARING.

TEMPERATURES SUNDAY NIGHT WILL BE SOME 10 TO 15 DEGREES COLDER THAN
SATURDAY NIGHT...AND SOME 15 TO 30 DEGREES COLDER ACROSS THE EASTERN
LAKE ONTARIO REGION. LOWS WILL DROP BACK INTO THE TEENS SOUTH OF
LAKE ONTARIO...WHILE ACROSS THE NORTH COUNTRY LOWS IN THE SINGLE
DIGITS...TO BELOW ZERO ARE LIKELY.

MONDAY BECOMES A LITTLE COMPLEX WITH LIGHT WINDS...AND LAND BREEZES
STEERING THE LAKE BANDS EARLY...WHILE SYNOPTIC SNOW ENTERS THE
REGION LATER. FOR THE MORNING HOURS WINDS BECOME LIGHT AS HIGH
PRESSURE FROM ONTARIO CANADA NOSES SOUTHWARD TOWARDS LAKE ONTARIO.
THIS WILL LIKELY ALLOW FOR LAKE EFFECT SNOW TO BECOME FOCUSED ALONG
THE IMMEDIATE LAKE ONTARIO SHORELINE...WITH POSSIBLY MUCH OF THE
SNOW REMAINING OVER THE BODY OF WATER.

WINDS OVER LAKE ERIE WILL BE A KNOT OR TWO STRONGER...ENOUGH THAT
LAKE EFFECT SNOW WILL LIKELY BEGIN TO SHIFT NORTHWARD TOWARDS
BUFFALO. A SHORTWAVE MONDAY OVER THE WESTERN GREAT LAKES WILL
QUICKLY RACE SOUTHEASTWARD DEEPENING THE LONG WAVE TROUGH OVER THE
EASTERN GREAT LAKES. THIS SHORTWAVE WILL LIKELY BRING SOME SYNOPTIC
SNOW ROUGHLY TO AREAS SOUTH OF THE THRUWAY. AS THE SHORTWAVE CARRIES
EASTWARD LATER MONDAY AND MONDAY NIGHT ACROSS
PENNSYLVANIA....SYNOPTIC SNOW WILL CARRY EASTWARD THROUGH THE FINGER
LAKES REGION.

BEHIND THE SHORTWAVE LAKE EFFECT SNOW WILL AGAIN RE-ENERGIZE OFF
BOTH LAKES MONDAY NIGHT THROUGH TUESDAY NIGHT. THOUGH INSTABILITY
WILL BE GREAT WITH EXTREME INSTABILITY AND LAKE EQUILIBRIUM LEVELS
RISING TO OVER 12K FEET LOW LEVEL OMEGA AND CONVERGENCE WILL NOT BE
AS GREAT...NOR IS THE AMBIENT MOISTURE. WILL CONTINUE WITH LIKELY TO
CATEGORICAL POPS DOWNWIND OF THE LAKES WITH SEVERAL INCHES OF SNOW
FALLING IN FAVORED LOCATIONS.

TEMPERATURES MONDAY AND TUESDAY WILL BE WELL BELOW NORMAL VALUES FOR
THIS TIME OF YEAR. MONDAY'S VALUES WILL BE SOME 10 TO 15 DEGREES
BELOW NORMAL...AND TUESDAY 15 TO 25 DEGREES BELOW NORMAL. LOOK FOR
HIGHS MONDAY TO BE IN THE TEENS NORTH COUNTRY TO LOW 20S SOUTH OF
LAKE ONTARIO...WHILE TUESDAY WILL LIKELY BE EVEN COLDER WITH HIGHS
IN THE SINGLE DIGITS NORTH COUNTRY TO TEENS SOUTH OF LAKE ONTARIO.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
THIS TIME PERIOD WILL CONTINUE WITH THE COLD CONDITIONS...AND LAKE
EFFECT SNOW...AND EVEN WITH A TEMPORARY BREAKDOWN OF THE AMPLIFIED
FLOW...EVEN THE WARMEST TEMPERATURES THIS PERIOD WILL STILL REMAIN
WELL BELOW NORMAL VALUES.

ON WEDNESDAY AN EASTERN PACIFIC TROUGH WILL BE PUSHING INLAND ACROSS
THE PACIFIC NW AND BRITISH COLUMBIA WHICH WILL ACT TO FLATTEN SOME
THE WESTERN RIDGE. MEANWHILE OVER THE EASTERN PORTION OF NORTH
AMERICA A STILL -1 TO -2SD TEMPERATURE ANOMALIES WILL BE CENTERED
NEAR QUEBEC WITHIN A DEEP LONGWAVE TROUGH WHOSE AXIS WILL BE ALONG
THE EASTERN COASTLINE.

AT 850 HPA TEMPERATURES WILL AVERAGE BETWEEN -19 TO -22C ACROSS THE
LAKES...WHICH ARE AROUND +2 TO +3C. THIS WILL YIELD EXTREME LAKE
INSTABILITY...THOUGH A MAJOR LIMITING FACTOR FOR SNOW WILL BE THE
LACK OF SYNOPTIC MOISTURE OVER THE LAKES. YET EVEN WITH THIS LIMITED
MOISTURE...FLUFFY LAKE EFFECT SNOW WILL LIKELY DEVELOP NEAR THE
LAKES...AND ESPECIALLY ALONG THE SOUTHERN SHORELINE OF LAKE ONTARIO
WHERE ADDED CONVERGENCE WILL BE FOUND.

THIS WEAK CONVERGENT BOUNDARY WILL SETTLE SOUTHWARD THROUGH
WEDNESDAY NIGHT SHIFTING THE LIKELIHOOD FOR LAKE EFFECT SNOW
SHOWERS FARTHER SOUTHWARD OFF LAKE ONTARIO...WHILE ENHANCING
ACTIVITY OFF LAKE ERIE. AN UPPER LEVEL SHORTWAVE CROSSING THE REGION
WEDNESDAY NIGHT WILL ALSO LIKELY ENHANCE SNOW SHOWER ACTIVITY...THUS
CONTINUING WITH CHC POPS FARTHER INLAND ACROSS THE SOUTHERN GENESEE
VALLEY AND FINGER LAKES REGION. WINDS WILL BECOME LIGHT THROUGH THE
NIGHT AND THE LAKE EFFECT SNOW BANDS MAY RETREAT CLOSER TO THE
SHORELINE UNDER A TEA KETTLE SCENARIO.

ACROSS THE NORTH COUNTRY EXPECT MAINLY DRY CONDITIONS WEDNESDAY AND
WEDNESDAY NIGHT AS COLD CYCLES SOUTHWARD AHEAD OF THE CENTER OF AN
ARCTIC HIGH OVER WESTERN QUEBEC.

THIS COLDEST AIRMASS OF THE SEASON WILL SEND TEMPERATURES WEDNESDAY
AND WEDNESDAY NIGHT SOME 10 TO 20 DEGREES BELOW NORMAL. HIGHS
WEDNESDAY IN THE TEENS SOUTH OF THE LAKES...AND SINGLE DIGITS IN THE
NORTH COUNTRY. TO PUT THIS COLDNESS INTO CONTEXT FOR THE NORTH
COUNTRY THE LAST TIME THE WATERTOWN AIRPORT HAD A DAY REMAIN IN THE
SINGLE DIGITS OR COLDER WAS JANUARY OF 2010.

THURSDAY LIGHT COLD NORTH WINDS WILL BE POURING OVER THE EASTERN
GREAT LAKES. WITH THESE LIGHT WINDS...EXPECT ANY SNOW EARLY THURSDAY
TO BE MORE OF THE TEA KETTLE...WITH LAND BREEZE CIRCULATIONS
FORMING THE BANDS OF LAKE SNOWS OVER THE LAKES. AGAIN THE LIMITING
FACTOR WILL BE THE LACK OF DEEP SYNOPTIC MOISTURE TO FEED INTO AND
FORM THESE LAKE EFFECT SNOW SHOWERS. AFTER SUNRISE...AND SLIGHT
WARMING OF THE LAND MASS THESE BANDS OF SNOW SHOULD BECOME MORE
CELLULAR...THOUGH POSSIBLY PUSHING INLAND WITH THE LIGHT NORTHERLY
SYNOPTIC FLOW. WILL AGAIN PLACE HIGHEST POPS JUST SOUTH OF THE
LAKES...WITH CHC FARTHER INLAND. HIGH PRESSURE OVER QUEBEC AND
NORTHERLY FLOW WILL CONTINUE WITH THE DRY DAY THURSDAY ACROSS THE
NORTH COUNTRY. THOUGH 850 HPA TEMPERATURES DROP A DEGREE OR SO
COLDER...WINDS WILL VEER TO SOUTHERLY THROUGH THE AFTERNOON...AND
MAY BRING A SLIGHTLY WARMER DAY ON THURSDAY TO THE REGION...THOUGH
STILL WELL BELOW NORMAL TEMPERATURES.

THIS CONVERGENT BOUNDARY WILL BEGIN TO FADE THROUGH THE DAY
THURSDAY...WITH LIKELY MANY AREAS FREE OF SNOW SHOWERS THURSDAY
EVENING. HOWEVER THE TROUGH THAT TEMPORARILY BROKE DOWN THE WESTERN
RIDGE WILL NEAR THE REGION LATER THURSDAY NIGHT. SOUTHERLY WINDS
AHEAD OF THE TROUGH WILL KEEP THURSDAY NIGHT NOT AS COLD AS PRIOR
NIGHTS...THOUGH A WIDESPREAD SYNOPTIC SNOW MAY BEGIN TO EFFECT THE
REGION LATER THURSDAY NIGHT AND THROUGH THE DAY ON FRIDAY. THIS
SOUTHERLY FLOW AHEAD OF THE TROUGH WILL INCREASE BOUNDARY LAYER
MOISTURE WITH NOW PLENTY OF MOISTURE IN THE SNOW GROWTH ZONE FOR
FORMATION OF DENDRITIC SNOWFLAKES. GIVEN THE TIME DISTANCE...WILL
CONTINUE WITH HIGH CHC POPS THURSDAY NIGHT AND FRIDAY...THOUGH
THOUGH THE 12Z GFS AND 12Z ECMWF ARE IN GOOD AGREEMENT WITH THIS
SHORTWAVE NEARING US WITH THE 12Z ECMWF SLIGHTLY FASTER.

BY SATURDAY THIS SYSTEM WILL BE WELL TO OUR EAST WITH AGAIN
TEMPERATURES ALOFT FALLING BACK TOWARDS -20C. THIS COLD NORTH TO
NORTHWESTERLY FLOW WILL MAINTAIN THE CHC FOR LIMITED LAKE SNOWS
DOWNWIND OF THE EASTERN GREAT LAKES. TEMPERATURES ON SATURDAY WILL
RETURN BACK TO SOME 10 TO 15 DEGREES BELOW NORMAL WITH HIGHS IN THE
TEENS SOUTH OF LAKE ONTARIO...AND LOW TEENS FOR MUCH OF THE
NORTH COUNTRY.

&&

.AVIATION /21Z SATURDAY THROUGH THURSDAY/...
VFR CONDITIONS WILL PREVAIL THROUGH THE FIRST HALF OF TONIGHT. AFTER
MIDNIGHT A STRONG COLD FRONT WILL CROSS THE AREA WITH A BRIEF PERIOD
OF RAIN/SNOW MIX CHANGING TO ALL SNOW...AND LIKELY PRODUCING MVFR
CONDITIONS. FOLLOWING THE PASSAGE OF THE COLD FRONT...EXPECT A MIX
OF VFR/MVFR CONDITIONS IN SCATTERED SNOW SHOWERS LATE TONIGHT
THROUGH SUNDAY...WITH STEADIER SNOW SHOWERS AND IFR DEVELOPING
SOUTHEAST OF THE LAKES SUNDAY AFTERNOON AS LAKE EFFECT SNOW BEGINS.

THE BIG STORY WILL BE WINDS. GUSTS IN THE 20-30 KNOT RANGE WILL BE
COMMON THROUGH THE REST OF TODAY. THIS EVENING THE SURFACE WINDS
WILL DIMINISH A LITTLE...BUT WINDS ALOFT WILL STRENGTHEN AS A LOW
LEVEL JET CROSSES THE AREA. THIS WILL PRODUCE SIGNIFICANT LOW LEVEL
WIND SHEAR THROUGH THE FIRST HALF OF TONIGHT.

AFTER 06Z A STRONG COLD FRONT WILL CROSS FROM WEST TO EAST ACROSS
THE REGION. JUST BEHIND THE COLD FRONT SURFACE WINDS WILL INCREASE
DRAMATICALLY...AND WILL PEAK SUNDAY MORNING WHEN WIND GUSTS MAY
REACH 50 KNOTS. WINDS WILL THEN GRADUALLY DIMINISH SUNDAY AFTERNOON.

OUTLOOK...
SUNDAY NIGHT THROUGH WEDNESDAY...PERIODS OF MVFR/IFR IN SNOW SHOWERS
AND LAKE EFFECT SNOW.
THURSDAY...VFR/MVFR WITH A CHANCE OF SNOW SHOWERS.

&&

.MARINE...
A RAPIDLY DEEPENING AREA OF LOW PRESSURE WILL MOVE BY JUST TO THE
NORTH OF THE REGION TONIGHT WITH A POWERFUL COLD FRONT CROSSING THE
LOWER LAKES AFTER MIDNIGHT. WINDS WILL BECOME SOUTHWEST TO WEST AND
RAPIDLY INCREASE OVERNIGHT AND PEAK SUNDAY MORNING. EXPECT SOLID 40
KNOTS SUSTAINED ON LAKE ERIE AND 45 KNOTS ON LAKE ONTARIO PRODUCING
HIGH END GALE WARNING CONDITIONS. WE CONSIDERED RAISING A STORM
WARNING ON THE EAST HALF OF LAKE ONTARIO...BUT FOR NOW WILL HOLD
WITH HIGH END GALES AFTER COORDINATION WITH ENVIRONMENT CANADA.
WINDS OF THIS MAGNITUDE WILL PRODUCE SIGNIFICANT WAVE HEIGHTS OF
ABOUT 15 FEET ON LAKE ERIE AND 20 FEET ON LAKE ONTARIO.

WINDS AND WAVES WILL BEGIN TO DIMINISH BELOW GALES LATE SUNDAY
AFTERNOON THEN DIMINISH FURTHER SUNDAY NIGHT AS THE PRESSURE
GRADIENT RELAXES.

&&

.TIDES/COASTAL FLOODING...
NORMALLY IN A STRONG WIND EVENT WE MAY HAVE SOME CONCERN FOR
LAKESHORE FLOODING ON LAKE ERIE...HOWEVER LAKE ERIE IS BELOW THE
HISTORICAL AVERAGE ELEVATION THIS WINTER. BECAUSE OF THIS LOWER
STARTING POINT...THE RISE IN ELEVATION DUE TO A SEICHE IS ONLY
EXPECTED TO RISE THE LAKE LEVEL TO AROUND 5-6 FEET ABOVE LOW
WATER DATUM...WELL BELOW THE 8 FOOT FLOOD STAGE.
