Frost Warning

Residents of Timmins, Ontario woke to a late season snowfall on Sunday. After very warm temperatures last week, most of the east is in for a very cold Monday with flurries and frost. ( Photo
After last weeks record warmth, it appeared we were finally past winter. Not so much this morning as very strong northwest winds have driven temperatures down to the single digits in Montreal. It was quite a cold and windy Mother's Day with temperatures struggling to reach 10C. By late afternoon another shot of cold air moved in with winds gusting to 70km/h and temperatures dropping to 4C. There was even reports of small hail here on L'Ile Perrot and some light snow in the Ottawa Valley and across the Laurentiens late last night. This morning it is blustery and cold with temperatures in the 2 to 4C range (35-40F) and windchill values below freezing. You will feel it when you step outside this morning as I did walking the dog. It will remain cloudy today with sprinkles and very windy once again 40-60km/h. Temperatures will reach 10C by this afternoon. Tonight, we have a frost warning in effect for metro Montreal and southern Quebec as well as the Champlain Valley. Lows by Tuesday morning will drop to near 0C (32F) with frost away from major metro regions. Frost warnings are also in effect for wide areas of southwest Ontario. Conditions will warm up moving into the middle portion of the week as a warm front begins to moderate temperatures with a chance of rain by Wednesday. At this time the first long weekend of the summer looks good with sunshine and warmer temperatures.

Over the weekend snow fell in northeast Ontario and portions of northwest Quebec with 26cm at Timmins and 30cm in Chapleau.
