Billings, MT – Montana residents can expect several days of seasonably warm weather this week, but gusty winds Monday and a developing weather system late in the week could bring a noticeable change across portions of the state.
According to the National Weather Service in Billings, temperatures will remain relatively mild through much of the week, with afternoon highs in the 60s and 70s before a possible shift toward cooler, windier and wetter conditions.
Wind Gusts Could Reach 40 MPH Monday Southeasterly winds are expected to increase Monday, October 19, particularly across far eastern Montana, where gusts could reach 20 to 40 mph.
Drivers of high profile vehicles should remain aware of changing crosswinds, especially along exposed highways.
Despite the breezy conditions, most locations will remain dry through the middle of the week.
Daytime temperatures are forecast to reach their warmest levels Thursday, while overnight lows generally range from the 30s to lower 50s.
Friday Rain Chances Increase Sharply Forecasters are monitoring a potential weather system that could bring precipitation, stronger winds and cooler temperatures late in the week.
Friday afternoon precipitation probabilities include:
Livingston: 85% Fort Smith: 80% Billings: 75% Roundup: 75% Big Timber: 70% Miles City: 60% These percentages represent the probability of measurable precipitation, not expected rainfall amounts.
Forecast Confidence Remains Limited The National Weather Service emphasized that confidence in the timing and impacts of the late week system remains low.
