Grand Forks, ND – The fall chill is sharpening across the Red River Valley this morning as cooler air slides in from Canada. Streets glisten from light overnight rain, and the air carries that late-October bite signaling change ahead. After a mild start, winds will shift Friday, dropping highs into the low 40s by Saturday with overnight lows near freezing.

According to the National Weather Service, residents in Grand Forks and East Grand Forks can expect a steady cool-down through the weekend. Friday may bring a mix of light rain and the season’s first trace of wet snow north of town. While no accumulation is expected yet, it marks the region’s earliest flirtation with winter conditions.

Saturday and Sunday turn breezy but mostly dry, with highs recovering slightly into the mid-40s and upper 50s by Sunday. Wind gusts up to 25 mph could make outdoor activities feel colder, especially during Halloween cleanups or late trick-or-treat events.

Looking further ahead, early November models show an active northern jet stream forming, raising the odds of measurable snow between November 8 and 21 across Minnesota, Wisconsin, Michigan, and parts of the Dakotas. Residents are urged to prep winter gear, check vehicle antifreeze, and finish outdoor yard work before next week’s colder surge sets in.

For now, the Red River Valley holds steady — but the first true taste of winter may be just days away.
