The temperatures will be much warmer tonight and Tuesday. West of the Alaska Range, lows tonight will be near 5°F and highs tomorrow will be in the mid to upper 20's. Due to higher elevations, the Rainy Pass checkpoint will likely be 10°F colder than this and the Rohn checkpoint will be about 3°F cooler.
The winds will remain out of the SSW tonight into tomorrow. The wind speeds in the stretch of trail ahead for Anna and Kristy will reach as high as 20-25 mph tonight and tomorrow. While the temperatures will be warmer than they were yesterday, the higher winds will keep wind chill temperatures below 0°F overnight and in the single digits during the day Tuesday.
Snowfall is highly likely for at least the next 24 hours. Accumulations will be from 1-4" tonight and an additional 1-3" during the day tomorrow. The highest chance for heavy snow will occur through Tuesday afternoon after which it will transition to light snow. This may reduce visibility, especially if the winds reach 20-25 mph
