TOTAL OF 15 TO 20 CENTIMETRES OF SNOW BY THIS AFTERNOON.
SNOWFALL WARNING FOR NORTH BAY – NIPISSING. SNOW HEAVY AT TIMES WILL CONTINUE THIS MORNING ACROSS THE NORTH BAY – NIPISSING REGION AS AN ALBERTA CLIPPER MOVES THROUGH FROM THE US MIDWEST. COLD SOUTHWESTERLY WINDS ARE PICKING UP ADDITIONAL MOISTURE FROM NORTHERN LAKE HURON AND ICE FREE AREAS OF GEORGIAN BAY AND AS A RESULT ARE ENHANCING THE SNOW ASSOCIATED WITH THE ALBERTA CLIPPER. THE SNOW WILL COME TO A QUICK END BY THIS AFTERNOON AS A SHARP ARCTIC COLD FRONT RACES THROUGH IN THE WAKE OF THE ALBERTA CLIPPER. TOTAL SNOWFALL AMOUNTS OF 15 TO 20 CM ARE EXPECTED BY THE TIME THE SNOW ENDS. MOTORISTS SHOULD BE PREPARED FOR DANGEROUS WINTER DRIVING CONDITIONS AND WHITEOUT CONDITIONS FROM BURSTS OF HEAVY SNOW AND ACCUMULATING SNOW. TRAVEL PLANS SHOULD BE ALTERED ACCORDINGLY. WIND CHILLS FOR A LARGE PART OF NORTHERN ONTARIO. AN ARCTIC HIGH PRESSURE RIDGE BUILDING INTO NORTHWESTERN ONTARIO HAS CAUSED WINDS TO DIMINISH TO 10 KM/H OR LESS ACROSS THE DISTRICT EARLY THIS MORNING. WITH LIGHT WINDS EXPECTED TODAY UNDER THE RIDGE EXTREME WIND CHILLS WILL NOT BE AN ISSUE. HOWEVER EXTREME WIND CHILLS MAY RETURN AGAIN ON WEDNESDAY AS WINDS PICK UP ONCE AGAIN IN ADVANCE OF YET ANOTHER BITTERLY COLD ARCTIC HIGH PRESSURE SYSTEM SLIDING SOUTHEAST ACROSS THE PRAIRIES. WIND CHILL WARNINGS MAY HAVE TO BE ISSUED AGAIN LATER TODAY OR TONIGHT FOR LARGE PARTS OF NORTHERN ONTARIO AS A RESULT.
