Cool down underway

A cold front has passed across the St. Lawrence Valley and is now south of Montreal. Most of the precipitation in the region is over after a couple of millimeters of rain and a trace of snow today. Winds have been gusty all day out of the southwest during most of the daylight hours and now the northwest gusting to 50km/h. The temperature started the day rather cold but rose dramatically at noon from -1C to 5C here in Montreal in a matter of minutes. My official high here on Ile Perrot was an unseasonably mild 6C at 1:47pm. It is slowly falling tonight with any wet surfaces expected to freeze up in the next few hours. We are currently 2C on Ile Perrot dropping to an overnight low of -11C.
