With an arctic air mass over our region and deep snow pack, temperatures fell rapidly last evening after sunset. We managed to reach –18C (0F) by 5pm here in Montreal, and dipped all the way down to –23C (-10F) at the airport at 7am and –25C (-13F) at my home. Skies will remain sunny today with the temperatures slowly warming to –13C for a high by late in the day. They will remain steady overnight tonight or slowly increase as skies cloud over and light snow develops from west to east. The snow will continue most of the day Friday but be very light with perhaps 2 to 4cm falling in the next 36 hours. Temperatures, on gusty southwest winds between 30-50km/h in the St. Lawrence Valley, will warm to –5C. The weekend at this point looks sunny for Saturday but more light snow Sunday from another clipper type system. Temperatures will be near normal, -3C for highs and –14C for lows.
Other cold spots last night included –28C at Sherbrooke, -27C at Mirabel and Kemptville, Ontario. Across the Adirondacks temperatures dropped as cold as –30C (-26F).
