Lewiston, Idaho

Headed out west this afternoon, to the rarely visited state of Idaho. Rarely visited by this site, anyway.

At 556PM, MT, Lewiston was reporting clear skies with a temperature of 78 degrees. A vast area of low pressure over western Wyoming was developing fairly widespread instability across the northern Rockies, including thunderstorms moving counterclockwise throughout the region. There were a few cells over the center of the state, east of Lewiston that were moving westward towards the city.
The upper level trough will pivot slowly towards the Plains, while the upper level low dig south into the southern Plains by early next week. As a result of these machinations, thunderstorms will become more infrequent in the northern Rockies, but Canadian and north Pacific air will continue to spill into the Idaho Chimney for a few more days, meaning Memorial ay will also be filled with clouds and rain.

Not everyone wants the showers in Lewiston, and hopefully there is plenty of blue sky for any northern Idaho cookouts. Here is the radar, showing storms moving towards Lewiston.
