Overview

  • Most areas stay warm and largely dry through Friday daytime under high pressure before conditions turn unsettled.
  • Storms are most likely Friday evening into early Saturday in parts of the Plains and Midwest, with Kansas City flagged for Friday night thunderstorms that may produce 50–60 mph gusts and small hail.
  • Great Lakes and Upper Midwest forecasts favor multiple rounds of rain Saturday into Sunday, with Metro Detroit eyeing around an inch or more and 30–40 mph wind gusts by Sunday.
  • Frost and freeze concerns persist in Pennsylvania, with frost advisories and a Friday morning freeze watch reported for parts of the state as clear, chilly nights continue.
  • Behind the front, cooler, drier air returns early next week; Tropical Storm Lorenzo is weakening over open water, and the Climate Prediction Center is monitoring the Caribbean for possible late-October development.
