Snow in late April
Despite the fact it was 17C today and sunny, the entire region is expecting some wet snow over the next 24-36 hours. Winter Storm Warnings are in effect for the Eastern Townships, the Beauce and Quebec City regions for 5 to 20cm of wet snow beginning overnight. An upper level low will slide across the St. Lawrence Valley with moisture and very cold temperatures funneling into the region on strong northeast winds. The heaviest snow will fall at levels above 1000 feet, but indications are that we may even see a slushy accumulation at lower elevations including Montreal where it will be a blustery 4C tomorrow. The snow is also expected in the Adirondacks of NY and northern Green Mountains of Vermont with nearly 30cm expected by Wednesday morning with Winter Storm Watches currently in place. Winds will be gusty out of the northeast from 40-70km/h in the St. Lawrence Valley. A cold rain will mix with snow for most of the event at lower elevations. The system will move to our east by late Wednesday. If travelling east along Highway 10 or 20 or south into Vermont on Interstate 89 and especially 91, expect low visibility and slippery roads at higher elevations. More information on this developing storm will be posted late tonight.
