Weather Trivia

Did you know?
The Dryden and Vermilion Bay region often sees above-normal dew points in late September—especially when easterly winds pull in moisture from the Great Lakes. These humid air masses lead to thick fog and muggy mornings, and increase the risk for afternoon pop-up thunderstorms, just like what’s possible today and Monday.

Keep the umbrella handy today—and prepare to trade it for sunglasses by midweek! Stay informed with the NetNewsLedger Weather Desk.
