SHORT TERM
Tonight through Thursday night...Dense fog has mostly mixed out of the region this afternoon as a low pressure system continues to move into the region tonight. Precipitation will start tonight, with snow falling across most of the region early Wednesday morning, then mixing to rain-snow mix through the mid-morning. Patchy fog will then reform in most lower elevation valleys this evening ahead of incoming precipitation.
Temperatures will continue to warm through the afternoon, with snow levels rising to 3500-4500 feet by the later afternoon.
Steady rain will fall for valleys below about 4000 feet through the evening, as the main warm front passes through by early afternoon. Rain and snow showers, some convective in nature, will then filter into the region with northwest winds as a weak cold front moves through by Wednesday evening. Rain will continue to be the main precipitation type through the evening for the Snake River Valley, with mountains switching back to snow by Wednesday night. Snowfall totals by Thursday morning over higher mountain summits will range from 8 to 12 inches, with mountain valleys seeing anywhere from 2 to 4 inches of snow.
McCall, ID has a forecast total of 3 inches of snow with about a 40% chance of exceeding 4 inches by Thursday morning. A few snow showers will linger in the West Central-Owyhee Mountains into Thursday morning, but accumulations will be minimal.
Temperatures will then continue a warming trend back to near normal by Thursday night.

LONG TERM
Friday through Tuesday...A broad upper ridge is still favored by all the models to strengthen across the west through the period, resulting in a warming trend from below-normal temperatures Fri-Sat to above normal Mon-Tue. However, fast-moving short wave upper troughs are progged to move through the Pacific Northwest for periods of precipitation, mainly over the weekend. Snow levels are expected to remain above valley floors for mostly rain in the lower elevations and rain/snow in the higher elevations. The bulk of the precip is shown to occur across the north, with Burns, Boise, and Jerome on the southern fringes of the precip.
