Glasgow, Mont. – Thunderstorms could disrupt weekend plans across northeast Montana as storm chances build Saturday afternoon and linger into Monday before a sharp turn toward dry, hot conditions.
According to the National Weather Service in Glasgow, a 30 percent chance of storms develops Saturday afternoon, with gusty east winds reaching 20 mph. Showers and storms become more likely Sunday, with a 40 percent chance of rain and isolated thunder rolling through Valley County. Monday brings another round of scattered storms, though the risk drops to 20 percent by evening.
The unsettled pattern could make travel tricky along U.S. Highway 2 and rural roads, especially during late afternoon and evening hours when storms are most likely. Gusts may exceed 25 mph in some areas, creating difficult driving conditions for high-profile vehicles. Residents are urged to keep an eye on weather alerts and avoid open areas during lightning.
By Tuesday, skies clear and heat builds, with Glasgow expected to reach 96 degrees. The drier stretch should continue through midweek, offering relief from the wet weekend but raising fire weather concerns.
Warnings and advisories may be issued if storms intensify, especially Sunday afternoon.
