First SNOW

10PM Update: The picture is grainy, but you get the idea. Snow is still falling here off the western tip of Montreal island. The temperature is currently 1C at my home. Surprisingly it is 0C at the airport but the observer is still reporting light rain. The snow is sticking to cars, trees and our lawn but not the pavement at this time. Watch for icy and slippery spots as the snow continues into the overnight period and the temperatures chill a degree or two more.

Update 8:05pm: As of 8pm the temperature has dropped to 1.7C here on Ile Perrot and the rain has changed to snow. It is still raining at the airport at 0.8C.

Low pressure and associated cold front is moving across the St. Lawrence Valley this evening. Cool air is spilling into the region and changing rain to snow across eastern Ontario and southern Quebec. At 7pm snow is falling in Ottawa at 0C and the temperature has dropped to 1C with light rain in Montreal. The rain should change to snow here before 9pm. Look for light wet snow to continue into the overnight hours. Accumulations will be from 2-4cm locally with higher amounts of 5-10cm across the higher elevations of upstate New York and Vermont. If you are travelling tonight watch for slick spots and lower visibility in any snow. At this time Halloween Sunday looks breezy and chilly with just a chance of showers for the trick or treaters.
