...CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS WITH GUSTY OUTFLOW
WINDS...

.DISCUSSION...
Moist southwest flow coupled with afternoon heating and instability
will fuel another round of afternoon showers and thunderstorms
across the central Idaho mountains. Thunderstorms will produce gusty
outflow winds to 40 mph that could channel through valleys and impact
the fire even if storms aren`t nearby. This pattern will remain locked
in place, keeping a chance of afternoon and evening thunderstorms in
the forecast through next week. Temperatures will remain near normal
with light terrain driven winds outside of thunderstorms.
