Winter returns for a day

Low pressure over the western Great Lakes is moving east across New York State tonight and Monday. The storm has already produced heavy rain in Windsor and Detroit with warnings in place there. The rain has caused flooding in spots. Nearly 50mm of rain has occurred with thunderstorms as well being reported. The precipitation is creeping into the GTA at this hour. In Eastern Ontario and Montreal it has been a spectacular day, plenty of sunshine and very mild spring like temperatures. All that will end overnight as the precipitation shield begins to edge towards Kemptville. Look for snow and sleet to begin overnight and taper to flurries Monday. Between 10-15cm may occur in Kemptville. Further southwest along the 401 from Brockville to Trenton freezing rain is expected and it may be quite steady in places. A Freezing Rain Warning is in effect for those regions.

Winter Weather Advisories are in place for New York State for the same  mixture of snow and freezing rain. Further north and east in Montreal and southern Quebec, we will remain on the extreme northern edge of the  precipitation. It may snow lightly in Montreal on Monday with gusty northeast winds, and much colder temperatures then today.
