Discussion: Multiple disturbances will traverse across the state throughout the next couple of days triggering off several rounds of showers and thunderstorms. In many locations these showers and storms will continue into the night. The greatest potential for severe weather is Sunday afternoon between state Route 200 and I-90, including the Lewistown area. Forecast models are indicating a line or band of storms will form as the storms move east with a high damaging wind potential (up to 75 MPH gusts are possible).
Showers and storms begin to wind down in central Montana Monday night. There will continue to be slight chances for showers and storms during the afternoon each day throughout the rest of the week. The storms will be isolated in nature and fueled by daytime heating as opposed to a larger system like we are seeing the next couple of days. Temperatures will also climb throughout the week peaking in the low 90s by Friday and next weekend.
