The episode as NWS BUF wrote it up.
A potent cold front crossed the region during the afternoon hours. Behind the front, windy conditions developed. Scattered power outages were reported across the western parts of the Niagara Frontier and the strong winds were funneled over Lake Erie. Sustained winds to 40 mph were measured at Niagara Falls International Airport and gusts to 61 mph were measured at Buffalo Niagara International Airport.

NWS Buffalo, NY wrote its last area forecast discussion before the first event at Dec 23, 7:54 PM EST, 50 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
754 PM EST SUN DEC 23 2007
.SYNOPSIS...
A STRONG LOW PRESSURE SYSTEM OVER THE UPPER PENINSULA OF MICHIGAN
WILL CONTINUE TO MOVE NORTHEAST INTO QUEBEC BY MONDAY MORNING AND
THEN INTO THE CANADIAN MARITIMES BY TUESDAY MORNING. A POWERFUL COLD
FRONT WILL CROSS THE REGION FROM WEST TO EAST BY EARLY THIS EVENING.
THIS FRONT WILL BE ACCOMPANIED BY HEAVY RAINFALL AND POSSIBLY STRONG
WINDS AND A FEW RUMBLES OF THUNDER. BEHIND THE COLD FRONT MUCH
COLDER AIR WILL RUSH INTO THE REGION WITH SNOW SHOWERS AND GUSTY
WINDS. LAKE EFFECT SNOW WILL DEVELOP NORTHEAST OF LAKE ERIE LATER
THIS EVENING AND NORTHEAST OF LAKE ONTARIO LATE TONIGHT. THE LAKE
SNOWS WILL CONTINUE NORTHEAST OF THE LAKES ON MONDAY BEFORE
WEAKENING AND PUSHING SLOWLY SOUTH ON CHRISTMAS EVE. MUCH MORE
TRANQUIL WEATHER IS THEN EXPECTED FOR CHRISTMAS DAY WITH JUST A
LITTLE LINGERING LIGHT LAKE EFFECT SNOW EAST OF LAKE ONTARIO.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
MANY CONCERNS IN THE NEAR TERM INCLUDING HEAVY RAINFALL...A FRONTAL
SQUALL LINE...GUSTY WINDS...AND LAKE EFFECT.
HEAVY RAINFALL...A 50 MILE WIDE SWATH OF MODERATE TO HEAVY RAINFALL
HAS DEVELOPED WITHIN THE WARM CONVEYOR AHEAD OF THE COLD FRONT WHERE
ANOMALOUSLY HIGH PWAT IS BEING DRAWN NORTH WITHIN THE INTENSE
SOUTHERLY LOW LEVEL JET. ANOTHER AREA OF HEAVY RAINFALL ASSOCIATED
WITH THE FRONTAL SQUALL LINE WILL COMBINE WITH THE FIRST AREA OF
HEAVY RAIN TO PRODUCE ABOUT AN INCH BASIN AVERAGE QPF FROM THE UPPER
GENESEE VALLEY INTO THE FINGER LAKES AND EASTERN LAKE ONTARIO
REGION. THERE MAY BE SOME LOCALLY HIGHER AMOUNTS WITH EMBEDDED
CONVECTION. THESE RAINS WILL BRING STREAMS AND SMALLER RIVERS TO
BANKFULL...AND WILL ALSO RESULT IN SUBSTANTIAL WITHIN BANK RISES ON
LARGER MAINSTEM RIVERS. WE WILL BE ISSUING URBAN/SMALL STREAM FLOOD
ADVISORIES TO HANDLE THIS ACTIVITY.
FRONTAL SQUALL LINE...A NARROW SQUALL LINE ALONG THE SURFACE COLD
FRONT CONTINUES TO SLOWLY INTENSIFY...BUT SO FAR IS NOT PRODUCING
ANY STRONG WINDS. THIS IS LIKELY DUE TO THE FACT THAT THE STRONG
WIND FIELD IS ORIENTED PARALLEL TO THE VARIOUS ENHANCED LINE
SEGMENTS WITHIN THE SQUALL LINE. WATER VAPOR IMAGERY SHOWING A
STRONG MID LEVEL VORTICITY MAXIMA AND JET STREAK WRAPPING AROUND THE
SOUTHERN EDGE OF THE DEEPENING MID LEVEL CYCLONE. SHORT TERM MODEL
GUIDANCE SHOWS THIS FEATURE EVENTUALLY CATCHING UP TO THE SURFACE
COLD FRONT AND SQUALL LINE. AS THIS OCCURS...LARGE SCALE FORCING FOR
ASCENT WILL INCREASE ATOP THE SQUALL LINE AND SHOULD RESULT IN
FURTHER INTENSIFICATION. AGREE WITH SPC THINKING IN SWOMCD
DISCUSSION THAT THIS FEATURE MAY ALLOW THE LOW/MID LEVEL WINDS TO
VEER TO BECOME MORE PERPENDICULAR TO THE SQUALL LINE. IF THIS WERE
TO OCCUR WE WOULD SEE THE COLD FRONT SURGE EASTWARD WITH AN
INCREASING DAMAGING WIND THREAT OVER THE EASTERN PORTION OF THE CWA
LATE THIS AFTERNOON AND EARLY EVENING.
POST FRONTAL WINDS...WINDS HAVE ACTUALLY DECREASED IMMEDIATELY
BEHIND THE COLD FRONT...LIKELY DUE TO A SHORT WAVE SURFACE RIDGE
JUST BEHIND THE FRONT AS SUGGESTED BY SHORT TERM NAM/WRF GUIDANCE
AND MSAS REAL TIME ANALYSIS. WINDS INCREASE AGAIN FARTHER WEST IN
THE STRONGER GRADIENT AND DEEPER COLD AIR ADVECTION WITH GUSTS IN
THE 35-40 KNOT RANGE ACROSS WESTERN OHIO AND SOUTHERN LOWER
MICHIGAN. WE WILL HOLD ONTO THE HIGH WIND WARNING INTO TONIGHT IN
EXPECTATION OF OUR WINDS ALSO INCREASING THIS EVENING AS WE GET
DEEPER INTO THE COLD AIR. WE MAY NOT SEE WARNING CRITERIA WINDS...
BUT IT WILL GET CLOSE AND MAY STILL LEAD TO SOME ISOLATED TREE AND
POWERLINE DAMAGE.
LAKE EFFECT...OUR FINAL CONCERN FOR TONIGHT IS LAKE EFFECT
POTENTIAL. INTENSE LOW LEVEL COLD AIR ADVECTION BEHIND THE FRONT
WILL ALLOW LAKE INDUCED INSTABILITY TO INCREASE RAPIDLY THIS
EVENING. LAKE INDUCED EQUILIBRIUM LEVELS RISE TO ABOUT 10 THOUSAND
FEET OVERNIGHT WITH LAKE INDUCED CAPE PEAKING AROUND 250J/KG. WHILE
THESE VALUES ARE NOT OVERLY IMPRESSIVE...THEY ARE SUFFICIENT FOR
ORGANIZED LAKE SNOWS. AMBIENT SYNOPTIC SCALE MOISTURE IS INITIALLY
SPARSE THIS EVENING WITHIN MID LEVEL DRY SLOT...HOWEVER OVERNIGHT
WRAP AROUND MOISTURE ADVECTS BACK INTO THE EASTERN GREAT LAKES WITH
A MORE FAVORABLE BACKGROUND MOISTURE PROFILE. SYNOPTIC SCALE FORCING
FOR ASCENT IS FAVORABLE WITH STRONG CYCLONIC FLOW IN THE LOW/MID
LEVELS. MAIN LIMITING FACTOR IS THE VERY STRONG WINDS. 850MB WINDS
ARE PROGGED TO BE AROUND 50 KNOTS OVERNIGHT...WHICH IS TYPICALLY THE
UPPER BOUND IN WHICH LAKE EFFECT CAN FORM. THE STRONG WINDS GREATLY
INCREASE THE EFFECTIVE SHEAR IN THE COLUMN...AND TEND TO TEAR THE
BANDS APART BEFORE THEY BECOME WELL ORGANIZED.
UPSTREAM RADARS SHOW LAKE SNOWS INCREASING IN INTENSITY OFF LAKE
MICHIGAN THIS AFTERNOON. IT SHOULD BE NOTED THAT 850MB TEMPS ARE
3-4C COLDER THERE THAN THEY WILL BE HERE. STILL...THAT IS A GOOD
SIGN THAT OUR LAKE EFFECT WILL BE ABLE TO FORM DESPITE THE STRONG
WINDS. GIVEN THE LIMITING FACTOR OF STRONG WINDS...HAVE OPTED TO
KEEP AMOUNTS IN ADVISORY CRITERIA. ASSUMING THE BAND FORMS...IT WILL
SET UP INITIALLY ACROSS THE NIAGARA PENINSULA INTO PORTIONS OF
NIAGARA AND ORLEANS COUNTIES AND POSSIBLY GRAND ISLAND LATER THIS
EVENING. THE BAND WILL PROBABLY NOT SINK SOUTH INTO METRO BUFFALO
AND GENESEE/MONROE COUNTIES UNTIL LATE TONIGHT.
HAVE KEPT THE LAKE EFFECT SNOW/BLOWING SNOW ADVISORIES IN
PLACE...BUT PUSHED BACK STARTING TIME UNTIL 00Z FOR NIAGARA/ORLEANS
AND NORTHERN ERIE COUNTIES AND 09Z FOR GENESEE COUNTY. ALSO ADDED
MONROE COUNTY TO THE ADVISORY STARTING AT 09Z GIVEN THAT THE STRONG
WINDS ARE LIKELY TO ALLOW THE LAKE BANDS TO PUSH WELL INLAND.
IT SHOULD BE NOTED THAT WHILE WE WILL HAVE LAKE SNOWS AND STRONG
WINDS...SINGLE BANDS OF LAKE EFFECT SNOW CREATE THEIR OWN LOCALIZED
WIND FIELDS WITH MUCH LIGHTER WINDS WITHIN THE BAND AND STRONGER
WINDS NEAR THE PERIPHERY. WE WILL NOT HAVE THE STRONG WINDS AND
HEAVY SNOW CO-LOCATED IN SPACE AND TIME...THEREFORE THERE WILL NOT
BE ANY BLIZZARD CONDITIONS.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
MAIN CONCERN WILL REVOLVE AROUND THE MESOSCALE THROUGH THE SHORT
TERM PERIOD WITH ONGOING LAKE EFFECT. THE AIRMASS WILL SLOWLY MODIFY
THROUGH THE PERIOD WITH 850MB TEMPS AROUND -11C AT 12Z MONDAY
WARMING TO NEAR ZERO BY WEDNESDAY.
OFF LAKE ERIE...EXPECT A BAND OF LAKE EFFECT SNOW TO BE ONGOING AT
12Z MON FROM THE NORTHERN HALF OF METRO BUFFALO NORTHEAST TO
ROCHESTER. LAKE INDUCED THERMODYNAMICS WILL DETERIORATE THROUGH THE
DAY WITH EQUILIBRIUM LEVELS FALLING TO AROUND 6 THOUSAND FEET BY
EVENING. EXPECT THE LAKE SNOWS TO REACH THEIR PEAK INTENSITY MONDAY
MORNING BEFORE SLOWLY DIMINISHING DURING THE AFTERNOON AND SINKING
SLOWLY SOUTH INTO THE SOUTHERN SUBURBS BY LATE AFTERNOON. WILL GO
WITH ADDITIONAL ACCUMS OF 3-5 INCHES IN THE MOST PERSISTENT BANDS.
AGAIN...THE STRONG WINDS ARE THE MAIN UNCERTAINTY WITH RESPECT TO
THE ABILITY OF LAKE SNOWS TO BECOME WELL ORGANIZED. IT IS POSSIBLE
THESE AMOUNTS MAY NEED TO BE INCREASED OR DECREASED SIGNIFICANTLY.
OFF LAKE ONTARIO...EXPECT A SIMILAR TREND TO LAKE ERIE ABOUT 6 HOURS
LATER. LAKE SNOWS WILL DEVELOP NORTH OF WATERTOWN ACROSS THE
THOUSAND ISLANDS BY MONDAY MORNING. THIS BAND WILL LIKELY DEVELOP A
DYNAMIC UPSTREAM CONNECTION TO THE LAKE ERIE BANDING FEATURE...WHICH
MAY AID IN FURTHER ORGANIZATION. THE STRONG WINDS WILL ALSO BE A
PROBLEM HERE AND MAY INHIBIT BAND ORGANIZATION. WILL CHANGE THE LAKE
EFFECT SNOW WATCH TO A LAKE SNOW/BLOWING SNOW ADVISORY AND RUN THIS
FROM EARLY MONDAY MORNING THROUGH 08Z TUE. BAND WILL SLOWLY SINK
SOUTH THROUGH WATERTOWN MONDAY TO THE TUG HILL MONDAY NIGHT.
UPSLOPING SHOULD AID IN CONTINUING ACCUMULATING SNOW ACROSS THE TUG
HILL INTO MONDAY NIGHT. A HEADLINE MAY EVENTUALLY BE NEEDED FOR
NORTHERN OSWEGO COUNTY...BUT WILL NOT CONSIDER FOR THIS PACKAGE.
LAKE SNOWS WILL END OFF LAKE ERIE BY EARLY CHRISTMAS MORNING AS
TEMPERATURES ALOFT BECOME TOO WARM TO SUPPORT LAKE EFFECT. SNOW WILL
END EAST OF LAKE ONTARIO BY CHRISTMAS AFTERNOON. CHRISTMAS NIGHT AND
WEDNESDAY SHOULD BE DRY WITH AT LEAST PARTIAL CLEARING AS A RIDGE OF
HIGH PRESSURE BUILDS INTO THE REGION.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
GOING TO KEEP THIS RELATIVELY SHORT CONSIDERING THE HIGH IMPACT
SITUATION WE ARE DEALING WITH IN THE SHORT TERM. AS INDICATED IN
PREVIOUS DISCUSSIONS, THE LONGWAVE PATTERN HAS BECOME VERY TYPICAL
OF A LA NINA COLD SEASON ACROSS THE NORTHERN HEMISPHERE...A SIGNAL
THAT THE ATMOSPHERE HAS FULLY COUPLED TO THE OCEANIC FORCING. THE
LONGWAVE PATTERN ACROSS NOAM WILL TRANSITION TO A TYPICAL LA NINA
BASE STATE DURING THE LONG TERM PERIOD WITH THE MEAN TROUGH
RELOADING ACROSS THE WEST AND RIDGING STRENGTHENING ACROSS THE
SOUTHEAST. THIS WILL CONTINUE TO PROVIDE AN ACTIVE SOUTHWEST TO
NORTHEAST STORM TRACK ACROSS THE NATION THROUGH THE LONG TERM. IN
OUR NECK OF THE WOODS IT ALSO STRONGLY SUGGESTS THAT ANY REALLY COLD
AIR IS NOT GOING TO SHOW ITS FACE AROUND HERE AT LEAST THROUGH NEXT
WEEKEND.
THE MODEL GUIDANCE IS COMING TOGETHER A BIT MORE ON THE TIMING AND
AMPLITUDE OF INDIVIDUAL SHORTWAVES MOVING OUT OF THE LONG WAVE
TROUGH IN THE WEST. NEWEST GFS ALONG WITH THE ECMWF AND VARIOUS
ENSEMBLE MEMBERS SHOW A WEAKENING SYSTEM MOVING TOWARDS THE OHIO
VALLEY AND NORTHEAST WEDNESDAY NIGHT THROUGH THURSDAY. ANOTHER
SYSTEM PROGGED TO MOVE THROUGH THE GREAT LAKES REGION LATE IN THE
WEEKEND WITH SOME DIFFERENCES IN TIMING. ONCE AGAIN, THE BIG NEWS IS
THAT THERE IS NO SIGNIFICANTLY COLD AIR IN STORE FOR US IN THE NEXT
WEEK OR SO.
&&
.AVIATION /01Z MONDAY THROUGH FRIDAY/...
THE COLD FRONT HAS MOVED THROUGH ALL TAF SITES. WE EXPECT
IMPROVEMENTS TO VFR IN SOME AREAS BUT LAKE EFFECT SNOW WILL BECOME
MORE ORGANIZED NORTHEAST OF BOTH LAKES OVERNIGHT. WE ALSO EXPECT
WIND GUSTS IN EXCESS OF 40 KNOTS ESPECIALLY IN FUNNELED AREAS
NORTHEAST OF LAKE ERIE.
MONDAY AFTERNOON AND MONDAY NIGHT CONDITIONS ARE EXPECTED TO BE MVFR
FOR CIG AND VFR FOR VSBY OVERALL. HOWEVER, A NARROW BAND OF LAKE
EFFECT SNOW IS EXPECTED TO REMAIN IN PLACE OFF BOTH LAKE ERIE AND
ONTARIO. OFF ERIE, THE 15 MILE WIDE BAND WILL BE BETWEEN KBUF AND
KJHW AND WILL PRODUCE LIFR CONDITIONS. OFF LAKE ONTARIO THE 20 MILE
WIDE BAND WILL BE LOCATED BETWEEN KART AND KSYR AND ALSO PRODUCE
LIFR CONDITIONS
LOOKING FURTHER AHEAD...HIGH PRESSURE WILL BUILD ACROSS THE AREA
TUESDAY ENDING THE LAKE EFFECT POTENTIAL. IMPROVEMENT TO VFR AT ALL
SITES IS EXPECTED TUESDAY THROUGH WEDNESDAY NIGHT. A WEAK FRONTAL
BOUNDARY IS EXPECTED TO CROSS THE AREA THURSDAY...BRINGING THE
POTENTIAL FOR SOME RESTRICTIONS TO CIG AND VSBY IN SNOW SHOWERS. NO
SIGNIFICANT WEATHER IS EXPECTED AT THIS POINT FOR THURSDAY NIGHT BUT
ANOTHER SYSTEM COULD BRING PRECIPITATION AND REDUCE PREVAILING
CONDITIONS TO THE AREA ON FRIDAY. TIMING ON THESE FEATURES HOWEVER
IS SUBJECT TO CHANGE.
&&
.MARINE...
MAIN CONCERN ACROSS THE EASTERN GREAT LAKES IS GALE AND STORM FORCE
WINDS TONIGHT. WINDS IN THE WAKE OF THE STRONG COLD FRONT WILL
STRENGTHEN OVERNIGHT AND WE WILL KEEP STORM WARNINGS FOR ERIE AND
GALES FOR ONTARIO.
MODEL GUIDANCE SHOWS THESE STRONG WINDS CONTINUING THROUGH ALL OF
MONDAY AND INTO MONDAY NIGHT AS THE INSTABILITY OVER THE WARM LAKES
ENSURES EXCELLENT MIXING OF THE STRONGER WINDS ALOFT DOWN TO THE
SURFACE. SEE NO NEED TO CHANGE THE TIME TAGS ON THE WARNINGS AT
THIS POINT.
BY TUESDAY THE MAIN LOW WILL MOVE OFF THE NEW ENGLAND COAST AND
LOOSEN ITS GRIP OVER THE EASTERN GREAT LAKES. WARNINGS WILL BE
DROPPED BY THEN.
THE REST OF THE WEEK LOOKS RELATIVELY QUIET.
&&
.TIDES/COASTAL FLOODING...
THE LAKESHORE FLOOD WARNING HAS BEEN CANCELLED. THE PEAK LAKE
LEVEL WAS 6.5 FEET JUST BEFORE 6 PM. FLODD STAGE IS 8 FEET. STRONG
SOUTHWEST WINDS WILL CAUSE THE LAKE LEVEL TO FALL AND RISE A
COUPLE MORE TIMES OVERNIGHT BUT IT WILL NOT GO AS HIGH AS THE
INITAL SURGE. HOWEVER WITH THE LAKE LEVEL HIGHER THAN RECENT DAYS
WE STILL EXPECT BEACH EROSION FROM 14 TO 18 FEET WAVES.
