Upper-Level Low Exits Central Montana, Winds and Storm Threats Persist

Overview

• The upper-level low moving out of central Montana will raise snow levels, end high-elevation mountain snow, and change remaining precipitation to rain as it tapers off.
• Strong gusty winds are expected to sweep into eastern Montana with peak gusts around 30 to 40 mph and periodic gusts over 20 mph elsewhere.
• Seasonable warming into the 70s and 80s will increase atmospheric instability and support daily afternoon shower and thunderstorm chances through midweek.
• A series of midweek shortwave disturbances could produce isolated severe storms with damaging winds, large hail, and rare tornadoes though exact timing and locations remain uncertain.
• Forecasts lean toward a milder, more stable holiday weekend with late-week conditions most unsettled and residents advised to stay weather aware for rapidly changing storms earlier in the week.
