Thunderstorms Through Tuesday

Pattern Change to Cooler and Showery Starts Wed

Planning to be outdoors Monday or Tuesday across the Northern Rockies? Scattered showers and thunderstorms are expected, especially during the afternoon and evening hours. Lightning, brief heavy rain, and gusty outflow winds will be the primary concerns.

A cool and showery pattern is expected to begin on Wednesday and last at least through the end of the week. Periodic showers and thunderstorms will bring wetting rains. There is a also slight chance (5-10%) of locally heavy rain causing debris flows on burn scars and flood prone areas. A significant rain event (0.50" or more) is looking more likely, with moderate to high confidence (50-70% chance). Daytime temperatures will also cool to seasonable levels.
