Tuesday: Tornado threat with today's severe storms
Storms will develop late Tuesday afternoon, but will diminish by midnight.
The greatest risk for severe weather will occur in the late afternoon, extending into the early evening hours, as well.

Initially, as the storms first push in, a risk for hail will be the primary hazard, but will transition to strong wind gusts and a tornado threat.
However, there is some uncertainty in the northward extent of instability and how far east the organized storm activity will reach. Regardless, be prepared for severe weather and take cover immediately, if threatening weather approaches.

Hot and humid conditions are expected to persist through Wednesday for the eastern half of the region, with temperatures reaching the upper 20s and lower 30s. Temperatures will remain very warm through Thursday for the Moosonee area, but most of the region will be much cooler.
