Thursday will become showery, gusty, and slightly cooler as a low pressure system approaches the region. Then, a strong cold front will pass through late Thursday night into Friday morning, lowering temperatures by 10-20 degrees and bringing windy conditions for Friday. Rain showers and high mountain snow will continue Friday morning, before tapering off from west to east Friday afternoon/evening.
A cluster of showers and thunderstorms moving south to north could produce strong outflow winds up to 60 mph, brief heavy rain, and small hail. Heavy rainfall will bring a flash flood threat over the Crooked and Wapiti burn scars, with a Flash Flood Watch in effect.
