Your Cortland County weather forecast for Monday, June 21, 2021:
An approaching cold front will clash with hot and humid air and a moderate jet stream aloft to bring a chance for scattered severe thunderstorms this afternoon.
The morning hours will be a mix of sun and clouds. A few showers lingering from thunderstorms across the Great Lakes last night will also be possible, mostly before 8 AM.
Then, this afternoon, lines of showers and storms will develop. Multiple rounds of thunderstorms will be possible. Any storms will be capable of damaging winds, large hail, and frequent lightning. Not every storm will become severe, though.
