Well, once again we find the upper low to the northeast of the area still having sway for the region for one more day.
Thursday morning the center of the low is located over Newfoundland, Canada and will open up as it moves northeastward in favor of another system diving southward through James Bay (we’ll get to that one in a moment).
So, for Thursday, overall we are looking at an unstable atmosphere, mainly in the afternoon with a general cyclonic flow aloft as well as embedded vorticity. This instability should be further aided by a slightly warmer afternoon as well as a bump up in surface dew points. This will mean showers and thunderstorms around during the afternoon, though it’ll be a lot of hit-or-miss activity, similar to Wednesday. These showers and thunderstorms will diminish Thursday evening with the loss of heating and some clearing should occur.
Friday, the previously mentioned James Bay system will have a short-wave trough break away from the main core of the low and it will dive southward through northern Ontario, but we’ll just warm up here on westerly winds.
