Special weather statement in effect for:
- Ottawa North - Kanata - Orléans
- Ottawa South - Richmond - Metcalfe
Very mild air makes a brief visit today, then windy and turning colder as winter returns by Tuesday.
A deep low pressure area over northern lower Michigan will track across Northeastern Ontario today then into Northwestern Quebec this evening. Most of the rain has quickly moved off into Quebec, with just scattered showers expected today. Very mild air will pay a brief visit to the regions today with temperatures getting into the low to mid teens in many areas, with even a few upper teens possible such as in the Cornwall area this afternoon.
Meanwhile a sharp Arctic cold front will blast east across the regions later today. It will be heralded by strong and gusty southwesterly winds, with gusts of 80 km/h being common over Southern Ontario and in Eastern Ontario near the north shore of Lake Ontario. A few gusts of 85 to 90 km/h are quite possible in some exposed areas. These strong and gusty winds will result in difficult driving conditions, especially on highways subject to strong cross winds.
Wind warnings are in effect for some locales near the Great Lakes.
Winter will return quickly tonight with temperatures in the wake of the front falling to just below freezing tonight, except in Eastern Ontario where they will drop to the low single digits. The return of colder air will result in the lake effect snow machine starting up tonight, with flurries to the Lee of the Great Lakes developing tonight. Snow squalls are possible over areas east of Lake Huron and Georgian Bay on Tuesday. Snow squall watches and warnings may be required as necessary.
