Good morning everyone!
As we gear up for the week, be sure to prepare for a wet weather pattern to develop across Idaho. In short— grab the umbrellas!
A low-level trough just off the coast will slowly inch inland to start the week. Ahead of the trough, southwest flow keeps temperatures mild and unseasonably warm.
WEATHER FORECAST: Valley rain, mountain snow forecasted through Wednesday
As the system moves inland, stronger westerly flow aloft taps into a deep plume of Pacific moisture, bringing widespread rain and mountain snow through Wednesday.
Snow levels will start around 5,000–6,000 feet today, then rise to 6,500–7,500 feet in northern areas and 7,500–8,500 feet in southern areas by Tuesday evening. Heavier snow will be confined above 6,000–7,000 feet, where 8–16 inches will be common, with locally higher amounts.
Higher elevation mountain valleys may see a wintry mix early, then transition mostly to rain.
The bulk of the moisture arrives on Tuesday, with widespread rain and mountain snow likely across the area.
Light mountain showers begin this afternoon in areas like McCall, but the steadier, more widespread precipitation develops late tonight and continues through Tuesday. Expect on-and-off showers mainly on Tuesday, with lingering precipitation into Wednesday as a weak cold front moves through the area.

Winds will remain breezy, with the strongest winds expected on Wednesday across the Magic Valley, where gusts could reach 35–45 mph.
That wind will kick up dust across the southern swath of the state, meaning— Don't wash the car just yet!
