A SIGNIFICANT SHIFT IN THE CURRENT WEATHER PATTERN IS ABOUT TO
UNFOLD ACROSS ONTARIO. A STRONG ARCTIC COLD FRONT SLICING SOUTHEAST
FROM THE NORTHERN PRAIRIE PROVINCES WILL COMBINE WITH PRONOUNCED
JET STREAM ENERGY EJECTING FROM THE AMERICAN SOUTHWEST TO SPAWN A
SIGNIFICANT STORM CENTRE OVER THE GREAT LAKES BEGINNING WEDNESDAY.

EARLY INDICATIONS ARE THAT THE STORM WILL MOST LIKELY MOVE THROUGH

NOTEWORTHY WEATHER CONDITIONS ACROSS THE NORTH. THIS WILL INCLUDE
APPRECIABLE RAIN..GALE FORCE WINDS..AND EVENTUALLY HEAVY SNOW AND
POTENTIAL OFFLAKE SNOWSQUALLS AS IT EVOLVES INTO A WINTERLIKE
STORM.

THE SIGNIFICANT SNOW WILL PROBABLY AFFECT REGIONS NEAR AND TO THE
NORTHWEST OF LAKE SUPERIOR. CONDITIONS MAY DETERIORATE RAPIDLY WITH
RAIN CHANGING TO SNOW OVERNIGHT TUESDAY NIGHT INTO WEDNESDAY MORNING
ACCOMPANIED BY SLIPPERY DRIVING CONDITIONS AS THE MERCURY FALLS

FALLING SNOW. AS A RESULT A WINTER STORM WATCH HAS BEEN HOISTED FOR
A BAND OF REGIONS EXTENDING FROM FORT FRANCES AND THUNDER BAY
NORTHEAST TO THE SIOUX LOOKOUT AND LAKE NIPIGON AREA.

FURTHER EAST RAIN IN ADVANCE OF THE STORM CENTRE WILL SOAK
NORTHEASTERN ONTARIO WEDNESDAY. AS THE COLD FRONT BLASTS ACROSS
THE DISTRICT IN THE WAKE OF THE STORM THURSDAY..SHOWERS WILL
BECOME MIXED WITH WET FLURRIES IN MANY AREAS..ALONG WITH TEMPERATURES
MORE TYPICAL OF NOVEMBER.

THE FIRST SIGNIFICANT LAKE EFFECT FLURRIES AND SNOWSQUALLS OF THE
SEASON MAY ALSO DEVELOP EAST OF LAKE SUPERIOR ON THURSDAY AND
PERSIST INTO NEXT WEEKEND IF THE AIRMASS GETS AS COLD AS CURRENT
INDICATIONS SUGGEST.

TRACK OF THIS STORM. ENVIRONMENT CANADA CONTINUES TO CLOSELY MONITOR
THE FORMATION AND TRACK OF THIS POTENTIALLY HIGH IMPACT STORM.

..BIG CHANGES ON TAP BEGINNING WEDNESDAY..

A SIGNIFICANT CHANGE IN THE WEATHER PATTERN IS ABOUT TO UNFOLD OVER
ONTARIO. THE SUMMERLIKE WEATHER WITH WARM AIR AND SUNSHINE OVER THE
THANKSGIVING WEEKEND HAS COME TO AN END WITH THE PASSAGE LAST NIGHT
OF A WEAK COLD FRONT TO JUST SOUTH OF THE LOWER GREAT LAKES. CLOUDS
AND PERHAPS THE ODD SPRINKLE WILL BE FEATURED TODAY ALONG WITH
TEMPERATURES ABOUT 5 DEGREES COOLER THAN YESTERDAY.

HOWEVER..A MORE SIGNIFICANT CHANGE IS ABOUT TO TAKE PLACE.

A SHARP ARCTIC COLD FRONT BLASTING TOWARDS THE DISTRICT FROM THE
PRAIRIES WILL UNITE WITH PRONOUNCED JET STREAM ENERGY EJECTING FROM
THE AMERICAN SOUTHWEST TO SPAWN A SIGNIFICANT FALL STORM OVER THE
GREAT LAKES ON WEDNESDAY.

INDICATIONS ARE THAT THE DEEPENING STORM CENTRE WILL MOST LIKELY
MOVE THROUGH LAKE SUPERIOR INTO NORTHERN ONTARIO WEDNESDAY.
INCREASING SOUTHERLY WINDS IN ADVANCE OF THE STORM CENTRE AND ARCTIC
FRONT WILL DRAW UP THE MILD AIR AGAIN FROM JUST SOUTH OF LAKE ERIE..
BUT THIS TIME ACCOMPANIED WITH SHOWERS AND ISOLATED THUNDERSTORMS.

THE ARCTIC FRONT WILL THEN BLAST ACROSS SOUTHERN ONTARIO WEDNESDAY
NIGHT ACCOMPANIED BY SHOWERS..STRONG WINDS..AND POSSIBLE
THUNDERSTORMS AGAIN. IN THE WAKE OF THE FRONT MUCH COLDER AIR WILL
QUICKLY FLOOD IN THURSDAY WITH TEMPERATURES PLUNGING TO VALUES
MORE TYPICAL OF NOVEMBER. AS A RESULT THE LAKE EFFECT MACHINE IS
EXPECTED TO KICK INTO GEAR..WITH SHOWERS NEAR THE GREAT LAKES AND
POSSIBLE FLURRIES AND SNOWSQUALLS INLAND OVER HIGHER GROUND TO THE
EAST OF LAKE HURON AND GEORGIAN BAY.

THE FIRST APPRECIABLE SNOWFALL OF THE SEASON IS POSSIBLE IN SOME
AREAS OF THE SNOWBELTS ALONG WITH LOCAL WHITEOUT CONDITIONS IN
BURSTS OF HEAVY SNOW AND LOCAL BLOWING SNOW. THIS WILL GIVE MOTORISTS
A FIRST TASTE OF HAZARDOUS WINTER DRIVING CONDITIONS.

IN ADDITION WATERSPOUTS WILL BE POSSIBLE OVER THE GREAT LAKES..
ALONG WITH GALE FORCE WINDS.

THIS IS AN EARLY ALERT TO THE POTENTIAL FOR SIGNIFICANT WEATHER.
THERE IS STILL SOME UNCERTAINTY IN THE TIMING AND TRACK OF THIS
DEVELOPING STORM. ENVIRONMENT CANADA IS CLOSELY MONITORING
THIS VERY INTERESTING SITUATION.

LISTEN FOR FURTHER STATEMENTS. ADDITIONAL INFORMATION
MAY ALSO BE FOUND BY CONSULTING THE LATEST PUBLIC FORECAST.
