Holiday Weekend Forecast Weekend Boating Forecast Memorial Day Climate Stats
After some patchy fog to start today, look for clouds to increase this afternoon as a weak boundary to stretch across the region. There is a chance for showers with isolated thunderstorms that may develop during the heating of the day. A better chance of showers arrive later tonight into Sunday as an upper-level trough of low pressure moves into the region and a surface low pressure passes to our south. These showers will be joined by a chance of thunderstorms on Sunday afternoon with locally heavy rain possible. The chance for showers continues into Memorial Day as a closed upper low moves across southern Ontario and an associated upper-level trough pushes into Wisconsin. The combination of cool air aloft and daytime heating will also bring a slight chance of thunderstorms to the region during the afternoon hours. Temperatures are forecast to be above normal today, but fall below normal by Memorial Day.
