Fort Wayne, IN – Clear skies and calm winds will allow temperatures to plunge across northern Indiana late Thursday night, bringing a widespread risk of patchy frost to open areas and low-lying fields. The National Weather Service in Northern Indiana warns that sensitive vegetation may be damaged if left uncovered overnight.
According to the National Weather Service, frost is most likely away from Lake Michigan, especially in rural and sheltered zones from Fort Wayne to Elkhart, and south toward the Wabash Valley. The coolest readings are expected early Friday morning, with lows dipping into the mid-30s. The same pattern may repeat late Friday night and again early next week as high pressure keeps skies clear.
Drivers on U.S. 30 and I-69 could encounter areas of reduced visibility before dawn due to light frost and shallow ground fog. Homeowners are urged to protect plants, bring pets indoors, and ensure outdoor hoses and sprinklers are drained to avoid damage.
Conditions will gradually moderate into the weekend, with highs rebounding to near 70 degrees by Saturday and plenty of sunshine. No precipitation is expected through early next week, though overnight lows will remain seasonably chilly.
According to the NWS, spotter activation is not anticipated during this period as stable air dominates the region.
