Area Forecast Discussion National Weather Service Boise ID 147 PM MST Wed Feb 11 2026

SHORT TERM
Tonight through Friday night...Showers dry up this evening with a slight chance lingering over higher terrain along the ID/NV border into Thursday. Increased moisture near the surface will lead to fog and low-cloud development across SE Oregon and areas of SW Idaho. Leaning toward low-clouds being the dominant feature in the lower Snake Plain with greater fog coverage across SE Oregon and higher terrain of SW ID (to include the western Magic Valley) where clouds will be more likely to intersect the terrain. In these areas have gone with dense fog wording but not enough coverage to warrant products.
Thursday is mostly dry with fog/stratus breaking by early afternoon. With the upper trough axis overhead, or just to the east, we could see afternoon 'popcorn' showers over the mtns of SE Oregon and w-central ID and have a slight chance (15%) to cover the potential. Another round of fog/stratus Thursday night as a flat ridge works in aloft. Clouds will increase on Friday as another trough approaches the West Coast and southwest flow increases moisture aloft. Temperatures through the period will be at or slightly above normal.

LONG TERM
Saturday through Wednesday...The long term continues to look wet and unsettled, with more cooling than previous forecasts as well. A deep longwave trough will remain positioned along the west coast as subsequent lows from the Gulf of Alaska keep it stalled and energetic through Wednesday. The forecast Saturday and Sunday calls for increasing clouds, with a 20-30% chance of precipitation. More widespread precipitation is expected north and west of the area, and will move in later in the long term. Over the weekend the wetter flow is kept out of the area by strong southwest flow aloft, which will keep temperatures about 5 degrees above normal. The low amplifies Monday and Tuesday and we move into the more favorable moisture band. Precipitation chances increase to 40-80% Monday evening through Tuesday, highest in mountains. Temps cool down to a few degrees below normal by Wednesday, and unsettled conditions continue.
