Daily Forecast: July 1, 2023
Tomorrow will bring another day full of a mix of sun and cloud to much of the region. Temperatures will remain warm and humid.
Poor air quality is expected once again tomorrow due to large concentrations of ozone near the surface, caused by the hot and humid temperatures. Some areas will continue to see smoke tomorrow as well, which may cause reduced visibility as well as poor air quality.
We will be monitoring the potential for some severe weather in Eastern Ontario tomorrow afternoon and evening. More forecast details will be posted in an update tomorrow when more data becomes available.
Several alerts remain in effect tonight due to ongoing severe thunderstorms in Midwestern Ontario. More thunderstorms are expected through the late night hours.
Happy Canada Day from Advance Weather!
