DISCUSSION

Issued at 1059 AM MST Wed Nov 11 2026

High pressure continues to build and shifts east through Friday. We remain on the dry side other than some high and mid level clouds streaming across the state. Temperatures will remain ABOVE AVERAGE with 50s and 60s for highs. We will need to see if the downslope pushes above the low/mid 60s across portions of the Snake Plain, Magic Valley, and adjacent bench areas.

The first wave or low crosses the state Friday evening through Saturday night. While we will see some light precipitation across the Wood River Valley and Sawtooths later in the evening, the bulk of the moisture falls after midnight through late Saturday afternoon and early evening. With the storm splitting and the main low drops southeast toward the Four Corners, the bulk of the moisture will be across the Wood River Valley, Sawtooths and surrounding mountains, South Hills/Albion Mountains, and the southeast highlands. Other areas will see light precipitation overall. Those areas mentioned are looking at 0.25-0.50" for totals in terms of rain or melted snow. There a few spots across the highest elevations of the mountains around Ketchum and the South Hills/Albion Mountains are pushing 0.50-0.70". Amounts are similar across most versions of the GFS and ECMWF, including ensembles and AI versions...although there are some spatial differences with the amounts closer to the Utah border. The AI version of the GFS is an extreme outlier is pushing more than 1" across the spine of the Sawtooths, which we are currently not going to account for due to the extremeness of the totals. Snowfall will generally be above 7000ft, although some higher valleys like the Stanley Basin will see some light accumulations. Totals will generally up to 3" with another 1-2" where we see higher pockets of precipitation. Temperatures drop back into 30s and 40s for highs. We will see a few showers lingering Sunday, but mostly dry until the next low shifts inland. The Blend of Models brings moisture Sunday night, but the overall trends have been to hold off until Monday...or at least shifting the bulk of the moisture in Idaho. The pattern with the storm looks very similar, with split flow and the bulk of the storm passing to our south. Temperatures briefly rebound 5-10 degrees vs Saturday, but quickly drop again once the lows moves our way.
