Grandma's Marathon Weather Watch

Grandma’s Marathon weekend in Duluth is turning wet—especially Friday—with showers and thunderstorms likely to drench afternoon events like the William A. Irvin 5k. Rain totals could hit half an inch, so pack your gear. While Thursday brings scattered light rain and cooler temps, the real drama hits Friday, with northern Minnesota bracing for soaked runners. But don’t despair—Saturday clears up beautifully under a high-pressure system, delivering mid-60s temps, light winds, and ideal marathon conditions. Just weather through Friday’s downpour and enjoy the sunshine on race day. Support the show:Get a discount at https://solipillow.com/discount/dnn.
