Weekend Update

The image above is from NOAA in the US and shows the plume of smoke extending from the Quebec wildfires north of Montreal southeast across our region and into New England this past Monday.

Showers overnight have ended this morning with just some low clouds and fog persisting in most areas. Skies will clear out and it will be a sunny, slightly humid, and warm day with temperatures either side of 25C across the area. Low pressure in the Great Lakes will move across the St. Lawrence Valley with showers and thunderstorms beginning overnight and continuing into Saturday. The anticipated cloud cover will keep temperatures down around 20C both Saturday and Sunday. A second area of low pressure over the Ohio Valley will slide to the east and just to the south of Montreal on Sunday. The track of this system may keep most of the precipitation south of the city, but we can't rule out a stray shower. The annual Tour de L'Ile will be running in Montreal on Sunday with thousands of cyclists participating. While it will be a decent day, bringing a raincoat along for the ride is not a bad idea.
