...SIGNIFICANT LAKE SNOWS WILL REDEVELOP ON WEDNESDAY...

.WHILE THE LAKE SNOWS FROM THE OVERNIGHT WILL CONTINUE TO WEAKEN
SOUTH OF BUFFALO AND OVER OPEN WATERS OF LAKE ONTARIO...THE STAGE
IS BEING SET FOR ANOTHER IMPRESSIVE ROUND OF LAKE SNOW.

A WEAK AREA OF LOW PRESSURE THAT WILL PASS JUST JUST TO THE SOUTH
OF NEW YORK STATE TODAY IS RESPONSIBLE FOR DISRUPTING AND
DISSIPATING LAST NIGHTS LAKE SNOW BANDS. AS THIS SYSTEM MOVES OFF
THE COAST OF LONG ISLAND TONIGHT...WESTERLY WINDS IN ITS WAKE WILL
ONCE AGAIN GENERATE SUBSTANTIAL SNOWFALL FOR AREAS EAST OF LAKE
ONTARIO. 

UNLIKE PREVIOUS LAKE ONTARIO SNOW BANDS THAT HAVE TARGETED AREAS
SOUTHEAST OF THE LAKE (IE. SOUTHERN OSWEGO COUNTY)...THE UPCOMING
LAKE SNOWS WILL IMPACT THE TUG HILL PLATEAU. THE LAKE SNOWS WILL
START ON WEDNESDAY MORNING...THEN WILL BECOME BETTER ORGANIZED
INTO A SINGLE PLUME OF HEAVY SNOW FOR THE AFTERNOON AND OVERNIGHT. 

THE SNOW WILL ALSO BE ACCOMPANIED BY INCREASING WESTERLY WINDS
WHICH COULD GUST TO 30 MILES AN HOUR AT TIMES. THIS WILL LIKELY
LEAD TO WHITEOUT CONDITIONS AND VERY HAZARDOUS DRIVING
CONDITIONS...WITH ONE TO TWO FEET OF WIND BLOWN FRESH POWDERY SNOW
REDUCING THE VISIBILITY TO A HUNDRED FEET AT TIMES.

30 MPH WILL RESULT IN HAZARDOUS DRIVING CONDITIONS.

IN LAKE EFFECT SNOW THE WEATHER CAN VARY FROM LOCALLY HEAVY SNOW
IN NARROW BANDS TO CLEAR SKIES JUST A FEW MILES AWAY. IF YOU WILL
BE TRAVELING ACROSS THE REGION BE PREPARED FOR RAPID CHANGES IN
ROAD AND VISIBILITY CONDITIONS.

NATIONAL WEATHER SERVICE BUFFALO NY
959 AM EST WED JAN 31 2007

...SIGNIFICANT LAKE SNOWS WILL CONTINUE THROUGHOUT TODAY...

.A COLD WEST TO SOUTHWEST OF AIR OVER THE EASTERN GREAT LAKES WILL
PRODUCE MORE SIGNIFICANT LAKE SNOWS THROUGHOUT TODAY. THE FLUFFY
LOW WATER CONTENT LAKE SNOW WILL BE ACCOMPANIED BY WINDS GUSTING
TO 30 MILES AN HOUR AT TIMES...SO ALONG WITH THE ACCUMULATIONS...
THERE WILL BE SOME BLOWING AND DRIFTING SNOW TO CONTENT WITH AS
WELL. 

FRESH SNOW ACCUMULATIONS FOR THE MIDDAY AND AFTERNOON WILL
GENERALLY RANGE FROM 6 TO 12 INCHES ACROSS THE WESTERN SOUTHERN
TIER...BUT A VERY IMPRESSIVE PLUME OF HEAVY LAKE SNOW OFF LAKE
ONTARIO WILL LIKELY PRODUCE MORE THAN A FOOT OF FRESH POWDER TO
THE TUG HILL PLATEAU.

GUSTY WINDS TO 30 MILES AN HOUR WILL BE PRESENT EAST OF LAKE
ONTARIO AS WELL. THIS WILL LEAD TO WHITEOUT CONDITIONS AND VERY
HAZARDOUS DRIVING CONDITIONS...WITH OVER A FOOT OF WIND BLOWN
FRESH POWDERY SNOW REDUCING THE VISIBILITY TO NEAR ZERO AT TIMES.

WHILE THE LAKE ERIE SNOWS WILL DIMINISH IN COVERAGE AND INTENSITY
THIS EVENING...ADDITIONAL SIGNIFICANT LAKE SNOWS WILL PERSIST

COUNTY.

THE SNOW WILL TAPER OFF LATE THIS AFTERNOON AS WINDS WILL BECOME
LESS FAVORABLE FOR LAKE SNOW PRODUCTION ACROSS THE REGION.

THIS ROUND OF LAKE SNOW WILL BE ACCOMPANIED BY WIND GUSTS TO 30
MILES AN HOUR...AND BECAUSE OF THE LOW WATER CONTENT OF THE

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BUFFALO NY
409 AM EST TUE JAN 30 2007

.UPDATE...

SNOW BAND OVER LAKE ERIE HAS BECOME DIFFUSE OVER LAND WITH LIGHT
SOUTHERLY WINDS DEVELOPING AHEAD OF THE SURFACE LOW. THE LAKE SNOW
WARNING FOR NORTHERN ERIE COUNTY HAS BEEN DROPPED.

&&

.PREV DISCUSSION...
/ISSUED 340 AM EST TUE JAN 30 2007/

SHORT TERM /TODAY THROUGH THURSDAY/...

LAKE SNOWS CONTINUE EARLY THIS MORNING BUT SHOULD BECOME MORE
DIFFUSE AS THE DAY WEARS ON, AND A CLIPPER SURFACE LOW BRINGS IN
WIND SHEAR. OVER LAKE ONTARIO, THE BAND ACROSS EASTERN WAYNE AND
NORTHERN CAYUGA COUNTIES HAS WEAKENED, HOWEVER THE BAND HAS
STRENGTHENED FURTHER WEST, WITH A COUPLE INCHES NOW POSSIBLE ALONG
THE SHORE IN NIAGARA AND ORLEANS COUNTIES. THE 06Z NAM KEEPS THE 925
MB OMEGA FEATURE JUST OFF SHORE.

OFF LAKE ERIE, THE STRONG OMEGA AT 12Z OVER ERIE COUNTY
DISSIPATES AT 15Z, WHICH SHOULD ALLOW THE BAND TO WEAKEN. WITH THE
BAND STILL SHOWING GOOD REFLECTIVITY ON RADAR, WE WILL LET THE DAY
SHIFT DROP THE WARNINGS WHEN THE BAND WEAKENS.

THE CLIPPER BRINGS A GENERAL LIGHT SNOW TODAY SOUTH OF LAKE
ONTARIO, AND THEN OROGRAPHIC CONVERGENCE BRINGS GOOD UPLIFT IN THE
NORTHWEST FLOW OFF LAKE ERIE...WE HAVE THUS ISSUED LAKE SNOW
ADVISORIES FOR CHAUTAUQUA CATTARAUGUS AND SOUTHERN ERIE COUNTIES
FOR TONIGHT AND WEDNESDAY.

OFF LAKE ONTARIO FLOW IS MORE WESTERLY, AND THE OMEGA IS
IMPRESSIVE INDEED. ANOTHER MODEL RUN IS NEEDED FOR CONFIRMATION,
SO WE HAVE ISSUED A LAKE SNOW WATCH FOR WEDNESDAY AND WEDNESDAY
NIGHT. IF THE NAM IS CORRECT, OVER 2 FEET OF SNOW IS POSSIBLE.

A QUICK BURST OF HEAVY LAKE SNOW MAY MOVE THROUGH THE BUFFALO AREA
WEDNESDAY NIGHT AS WINDS BACK AHEAD OF THE NEXT TROUGH.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...

WHILE THERE IS ABSOLUTELY NO DOUBT THAT TEMPERATURES DURING THIS
PERIOD WILL AVERAGE BELOW NORMAL...WE WILL BE LOSING OUR MUCH
PUBLICIZED CROSS POLAR FLOW. INSTEAD...A DEEP POLAR VORTEX WILL
REMAIN IN PLACE OVER EASTERN CANADA WITH SOME OF COLDEST AIR OF
THE NORTHERN HEMISPHERE CONTAINED WITHIN IT. IN A SENSE...WHAT
WILL BE MORE EVIDENT DURING THE PERIOD WILL BE A HIGH AMPLIFIED
+PNA PATTERN ALTHOUGH THE EFFECTS OF THE NAO CANNOT BE IGNORED.

THE BLOCKING GREENLAND RIDGE (-NAO) THAT HAS BEEN IN PLACE IS
EXPECTED TO BRIEFLY WEAKEN...AND THIS WILL ALLOW THE VORTEX TO
SETTLE TO THE SOUTH BEFORE TRYING TO LIFT OUT TO THE EAST. MEDIUM
RANGE GUIDANCE SHOWS THAT JUST AS THIS VORTEX TRIES TO LIFT OUT TO
THE NORTHEAST...THE GREENLAND BLOCK WILL ONCE AGAIN BECOME
ESTABLISHED. THIS WILL KEEP THE DEEP LONG WAVE TROUGH OVER THE
EASTERN TWO THIRDS OF NORTH AMERICA WITH ITS ASSOCIATED COLD AIR
REMAINING FIRMLY LOCKED IN PLACE.

THE WEAKENED STATE OF THE CURRENT EL NINO MAY HAVE HAD A HAND IN
ALLOWING THIS WHOLE PATTERN TO DEVELOP OVER THE PAST FEW WEEKS...BUT
THAT IS A DISCUSSION FOR A LATER TIME.

THE EFFECTS OF ALL OF THIS WILL BE THAT THE COLDEST AIR OF THE
SEASON IS FORECAST TO DROP OUT OF EASTERN CANADA DURING THE COURSE
OF THE WEEKEND AND EARLY NEXT WEEK. H8 TEMPS HAVE BEEN AVERAGING -15
TO -20C IN THE MOST RECENT COLD SPELL...BUT H8 TEMPS WILL LOWER TO
BETWEEN -22 AND -26C BY THE END OF THIS FORECAST PERIOD (SUN-MON).

SINCE THE LAKES ARE STILL WIDE OPEN (FOR THE TIME BEING)...THE
BITTERLY COLD AIR WILL CERTAINLY CONTINUE TO GENERATE LAKE SNOWS
WITH THE LAKE SNOW BELTS SOUTHEAST OF BOTH LAKES BEING THE FAVORED
REGIONS FOR MORE SIGNIFICANT ACCUMULATIONS. REGIONWIDE...SCT -SHSN
WILL BE COMMON PLACE DURING THE PERIOD WITH SFC TEMPS AVERAGING AT
LEAST 10 TO 15 DEGREES BELOW NORMAL FOR THE WEEKEND THROUGH EARLY
NEXT WEEK. NOW FOR SOME DETAILS...

A FAIRLY VIGOROUS SHORTWAVE WILL CROSS THE UPPER GREAT LAKES ON
FRIDAY. H8 TEMPS LOOK LIKE THEY WILL BE JUST A LITTLE TOO MILD AT
THAT TIME FOR ANY REAL LAKE EFFECT...ALTHOUGH WEAK SYNOPTIC LIFT
FROM THE PASSING SHORTWAVE COUPLED WITH SOME LAKE ENHANCEMENT WILL
BE ENOUGH TO WARRANT AT LEAST CHC POPS FOR SOME -SHSN.

AS THE SHORTWAVE WILL LIFT OUT ACROSS QUEBEC FRIDAY NIGHT AND
SATURDAY...THE LEADING EDGE OF THE NEXT ARCTIC AIRMASS WILL POUR
ACROSS THE EASTERN GREAT LAKES. THIS WILL RESULT IN WIDESPREAD -SHSN
FOR THE REGION WITH SIGNIFICANT LAKE SNOWS ANTICIPATED FOR SITES
SOUTHEAST OF THE LAKES.

A REINFORCING SHOT OF TRUE ARCTIC AIR MOVE ACROSS THE REGION LATER
SUNDAY INTO MONDAY WITH THE LAKE EFFECT MACHINE IN HIGH GEAR. SFC
TEMPS ACROSS THE REGION FOR SUNDAY AND MONDAY WILL NOT MAKE IT OUT
OF THE TEENS WHILE OVERNIGHT LOWS WILL RANGE FROM THE SINGLE DIGITS
IN MOST AREAS TO BELOW ZERO ACROSS THE NORTH COUNTRY AND IN SOME OF
THE DEEPER SOUTHERN TIER VALLEYS.

AVIATION /08Z-06Z/...

BAND OF HEAVY LAKE EFFECT SNOW CONTINUES TO CREEP NORTH TOWARDS
THE KBUF TERMINAL. VWP PROFILE OFF CLE RADAR ALREADY SHOWING SOME
SIGNS OF VEERING IN THE LOWEST FEW KM...AND EXPECT LAKE ERIE BAND
TO REACH ITS NORTHERNMOST POSITION OVER THE NEXT FEW HOURS.
NORTHERN EDGE OF BAND MAY IMPACT KBUF WITH RESTRICTED VSBY/CIGS
THROUGH ABOUT 09Z BEFORE BEGINNING TO SETTLE SOUTH. EXPECT THE
CORE OF THE BAND WITH THE MOST INTENSE SNOWFALL RATES TO REMAIN
JUST SOUTH OF THE TERMINAL...BUT IT WILL BE VERY CLOSE.
ELSEWHERE...ALL OTHER TERMINALS SHOULD REMAIN BETWEEN LAKE BANDS
THROUGH MOST OF THE PERIOD. APPROACH OF WEAK CLIPPER ON TUESDAY
AND CORRESPONDING INCREASE IN LOW LEVEL MOISTURE SHOULD BRING A
DETERIORATION OF CIGS FROM W TO E. SUBTLE UPSLOPE FLOW DURING TUE
AFTERNOON WITHIN DEVELOPING COL REGION NW OF CLIPPER LOW MAY BRING
SOME LIGHT SNOW TO THE WESTERN TERMINALS...ESPECIALLY KROC WHICH
MAY RECEIVE SOME ENHANCEMENT OFF LAKE ONTARIO LATE IN THE PERIOD.

MARINE...

A CLIPPER LOCATED OVER NORTHERN MICHIGAN EARLY THIS MORNING WILL
CONTINUE TO TRACK TO THE EAST AND CROSS SOUTHERN NEW YORK
STATE/NORTHERN NEW YORK STATE THIS AFTERNOON. VARIABLE WINDS WILL
KEEP WAVES UNDER SMALL CRAFT ADVISORY CRITERIA TODAY...BUT AS THE
WESTERLY GRADIENT TIGHTENS BEHIND THE DEPARTING LOW...WINDS AND
WAVES WILL LIKELY RESULT IN SMALL CRAFT ADVISORY CONDITIONS OVER
THE EASTERN END OF LAKE ERIE TONIGHT AND ALONG ALL NEARSHORES ON
BOTH LAKES ON WEDNESDAY.
