A sharp cooldown is expected to hit northeast Montana this week, with temperatures dropping from highs around 60°F on Monday to the 30s and 40s by Tuesday. Rain showers on Monday will transition to a mix of rain and snow by Wednesday night, creating hazardous travel conditions across the region.

Why it matters

Sudden changes in weather can pose significant risks for drivers and outdoor activities in rural Montana, where long stretches of highway and county roads may become treacherous. The transition from mild, dry weather to a colder, wetter pattern could impact travel, school schedules, and other daily routines across communities along the Hi-Line.

The details

According to the National Weather Service in Glasgow, dry and seasonable conditions will hold through the weekend, with highs ranging from the low 50s to upper 60s. However, a cold front moving in on Sunday night will bring increasing chances for showers across the region into Monday. By Tuesday, colder air will push in, dropping highs into the 30s and low 40s, especially along the Hi-Line and U.S. Highway 2. The most significant change arrives by Wednesday night into Friday, when additional moisture combines with the colder temperatures to bring a mix of rain and snow, potentially creating slick travel conditions.

• Dry, seasonable conditions through the weekend (March 25-26)
• Cold front moves in Sunday night (March 26)
• Rain showers develop on Monday (March 27)
• Temperatures drop into the 30s and 40s on Tuesday (March 28)

What’s next

Residents should prepare for rapidly changing conditions, including wet roads transitioning to icy patches later in the week. Additional weather advisories are likely as precipitation type and timing become clearer.
