Fort Wayne, IN – Northern Indiana’s streak of unseasonably mild fall weather is about to come to an end. The National Weather Service (NWS) reports that a strong cold front will move through the region on Friday, bringing gusty winds, rain showers, and a sharp drop in temperatures by the end of the weekend. Residents should prepare for a dramatic shift from 60s to 40s, along with the potential for frost and even light snow in northern counties.
The Weather Pattern: From Warm Sunshine to Chilly Air
According to meteorologists with the NWS in Northern Indiana, Thursday will remain mostly sunny with comfortable highs between 55°F and 58°F, marking the last mild day before the cold front’s arrival. Winds from the southwest will gradually increase through the day, gusting up to 25 mph by Friday, ahead of the approaching system.
“The pattern shift will be quick and noticeable,” forecasters said. “Rain and strong winds will accompany the front Friday, followed by a much colder weekend.”
The mild, breezy conditions on Thursday will give way to widespread rain on Friday morning, continuing into the afternoon and tapering late Friday night. Behind the front, temperatures will drop sharply, falling into the 30s early Saturday and struggling to reach the mid-50s during the day.
Friday’s Cold Front and Rainfall Details
Friday will mark the arrival of a strong fall cold front, bringing a surge of moisture and wind across northern Indiana. Forecasters say rain will begin in southwestern counties by sunrise and become widespread by midday. Wind gusts between 25 and 30 mph will make travel feel even chillier.
By Friday evening, temperatures are expected to fall quickly, and the rain will transition to isolated showers overnight, setting the stage for a brisk weekend. While severe storms are not expected, heavier downpours may occur briefly during the frontal passage.
Weekend Forecast: A Chilly, Breezy Turn
Saturday will bring a noticeable drop in temperatures. Highs will only reach the low to mid-50s, with breezy northwest winds and lingering clouds. A few spotty showers could develop during the day, especially in northern counties.
By Sunday, a colder air mass will settle over the Great Lakes region. Daytime highs will struggle to reach the low 40s, and overnight lows could dip near freezing, leading to widespread frost by Monday morning.
“We’re watching for the season’s first widespread frost, especially across rural and outlying areas,” said NWS meteorologist Matthew Mosteiko. “Gardeners should plan accordingly.”
In far northern areas such as South Bend and LaPorte, colder air flowing over Lake Michigan could produce light lake-effect rain or snow showers, signaling the first taste of winter conditions.

It’s also a good time to switch to winter gear and check vehicle antifreeze levels ahead of the first major temperature drop.
Homeowners are advised to disconnect garden hoses, cover sensitive plants, and protect outdoor faucets as freezing conditions become possible Sunday night.
