Environment Canada has upgraded its storm watch to a storm warning for a large part of southern Ontario, stretching all the way east to Kingston, but so far Ottawa has not been issued a warning.

Ottawa can expect significant rain and ice pellets Thursday night and Friday, and significant ice pellets and snowfall amounts "in excess of 15 cm" are possible, along with the threat of freezing rain, the weather agency said.

CBC Ottawa climatologist Ian Black said the latest weather models show snow starting in Ottawa very early Friday with freezing rain a definite threat.

The weather agency also notes Friday is expected to be windy.

The long-range forecast calls for Saturday to be cloudy with a 70 per cent chance of flurries and a high temperature of 4 C. Sunday is expected to be sunny, and temperatures are expected to rise into next week.
