 NEXT WEATHER MAKER

Next 2 days (Wednesday & Thursday) will be very active across Montana. Wednesday is the day for severe storms to build over SW Montana especially east of the divide. Some storms could produce 1" or greater diameter hail and/or wind gusts up to or over 58 mph. Both can produce property damage. Locally heavy rainfall is possible with these storms and flash flooding is a concern Wednesday afternoon. Thursday the severe weather threat should shift over into Eastern counties of Montana but there is still a good chance we will see hit and miss afternoon thunderstorms across SW Montana.
