...Winter weather arrives this weekend...
A strong Pacific storm system will move into the northwest this weekend. Showers and a few thunderstorms will overspread central and southeast Idaho on Saturday...with snow only at the highest elevations. Saturday night...snow levels will fall dramatically resulting in snow falling at the valley floors including the Snake River Plain by Sunday morning.
Snowfall amounts will be heaviest across the northern mountains with 4 to 8 inches possible in the central mountains...and 3 to 6 inches possible in the upper snake Highlands and along the Idaho/ Montana border Saturday night and Sunday. The Snake River Plain may see snow accumulate along the I-86/I-15 corridor Sunday morning with around an inch possible on the valley floor and up to 3 inches on the benches. The southern Highlands can expect 3 to 5 inches in the mountains and around an inch in the valleys.
A small change in the track of the storm system could easily leave the Snake River Plain will little precipitation...while the situation for the mountains would likely remain unchanged.
Stay tuned for updates on this storm system. If traveling into the mountains...especially Saturday night and Sunday...be prepared for winter conditions.
