==DISCUSSION==

AN ALBERTA CLIPPER CURRENTLY TRACKING SOUTHEASTWARD THROUGH THE
DAKOTAS IS EXPECTED TO TRACK ACROSS THE US MIDWEST TONIGHT AND
THURSDAY THEN TRACK JUST SOUTH OF LAKE ERIE ON FRIDAY. THIS CLIPPER
MAY INTENSIFY INTO A WINTER STORM AS IT APPROACHES SOUTHERN ONTARIO.

SNOW AHEAD OF THIS CLIPPER WILL START SPREADING INTO SOUTHERN ONTARIO
FROM MICHIGAN AND LAKE HURON ON THURSDAY WITH PERHAPS A COUPLE CM OF
SNOW BY THURSDAY EVENING IN A SWATH OF REGIONS EXTENDING FROM LAKE
HURON TO WESTERN LAKE ONTARIO.

AS THE CLIPPER GETS CLOSER, LATEST INDICATIONS SUGGEST IT WILL
INTENSIFY THURSDAY NIGHT, WITH AN EXPANDING AREA OF HEAVY SNOW
EXPECTED TO MOVE INTO MOST OF SOUTHERN AND PARTS OF EASTERN ONTARIO.
SOME FREEZING RAIN AND ICE PELLETS ARE POSSIBLE OVER THE EXTREME
SOUTHWEST.

SNOW, HEAVY AT TIMES IS EXPECTED TO CONTINUE WELL INTO FRIDAY AS THE
STRONG CLIPPER SAILS BY JUST SOUTH OF THE GREAT LAKES.

MANY PARTS OF SOUTHERN AND EASTERN ONTARIO MAY RECEIVE 15 CM OF SNOW
FROM THIS STORM BY FRIDAY EVENING. SOME AREAS MAY RECEIVE HIGHER
AMOUNTS, WITH 25 CM NOT OUT OF THE QUESTION. THIS WILL DEPEND
ON THE EXACT TRACK AND INTENSITY OF THIS LOW, AND ENHANCEMENT IN
THE COLD EASTERLY FLOW OFF OF LAKE ONTARIO FOR EXAMPLE. TOTAL SNOW
AMOUNTS MAY BE SOMEWHAT LOWER OVER THE EXTREME SOUTHWEST DUE TO SOME
FREEZING RAIN AND ICE PELLETS.

BRISK EASTERLY WINDS WILL ALSO RESULT IN BLOWING SNOW IN MANY AREAS
THURSDAY NIGHT AND FRIDAY.

TRAVELLING CONDITIONS WILL DETERIORATE AND BECOME HAZARDOUS IN THE
SNOW AND BLOWING SNOW THURSDAY NIGHT AND FRIDAY. THERE MAY BE A
SIGNIFICANT IMPACT ON THE COMMUTE TO WORK ON FRIDAY MORNING AND
POSSIBLY FRIDAY AFTERNOON IN HEAVY SNOW AND BLOWING SNOW.

THERE IS STILL SOME UNCERTAINTY AS TO THE EXACT TRACK AND INTENSITY
OF THE LOW, WHICH WILL AFFECT WHERE THE HEAVIEST SNOW FALLS. HOWEVER
THE MANY OF LATEST COMPUTER MODELS HAVE CONTINUED TO SUGGEST A MORE
INTENSE VERSION OF THIS WINTER STORM IS POSSIBLE.

ENVIRONMENT CANADA IS CLOSELY MONITORING THIS SITUATION. THE
WINTER STORM WATCH MAY BE EXPANDED FURTHER TO THE NORTHEAST
AS THE EVENT DRAWS CLOSER. WARNINGS MAY ALSO BE ISSUED FOR MANY
REGIONS AS WELL.

REFER TO YOUR LOCAL PUBLIC FORECAST FOR FURTHER DETAILS.
