...CHANCE OF THUNDERSTORMS WITH GUSTY OUTFLOW WINDS EACH DAY...

A stationary weather pattern will keep southwest flow over the 
central Idaho mountains through the week ahead. Pacific moisture, 
coupled with afternoon heat and instability will lead to daily 
shower and thunderstorm development. The greatest threat for 
thunderstorms will to impact the fire site will be between 3 PM

aren't nearby. Locally heavy rain is also possible from 
thunderstorms. Temperatures will be near normal through the week 
with generally light terrain driven winds outside of thunderstorms.
