 NEXT WEATHER MAKER:

SW flow aloft is pushing monsoon moisture up into SW Montana Wednesday afternoon and evening. This is also pushing more wildfire smoke up into the region so look for worsening air quality. The biggest concern Wednesday afternoon and evening is garden variety thunderstorms. This means most storms will be weak but a few stronger storms are possible. Some storms could produce hail and stronger outflow winds and plenty of lightning. Hopefully most storms will also produce some brief moderate to heavy rainfall.
