Precipitation on the way

Another round of wet and wintry weather is upon us in eastern Ontario. Low pressure over the Midwest will slide down the St. Lawrence Valley late today and tomorrow. Along the storm track we can expect some snow changing to freezing rain and eventually rain overnight tonight in Kemptville. The type and duration of precipitation will be based on how quick the cold air is flushed out of the valley The rain snow mix is already into the GTA and should move into our region this evening. Expect 20-25mm of rain and snow over the next 24 hours. With milder air Wednesday I expect mostly rain. The roads could be slippery tonight and and early Wednesday, especially in the Ottawa Valley.

While no warnings are in place for Ontario, a Winter Weather Advisory is in place for all of northern New York State including Ogdensburg and Watertown. They are forecasting 5-12cm of snow before the changeover to rain tonight.
