A cold front moving through Friday will bring cooler temperatures and the potential for the season's first snowflakes in valley locations, including the Treasure Valley and Magic Valley, as winter weather patterns begin to establish across Idaho.

Today Through Friday: Cold Front Arrival

An upper-level trough will move through all day Friday, bringing a cold front Friday morning. Fog may reform in sheltered valleys Friday morning as surfaces remain fairly saturated, though pre-frontal winds and partly cloudy skies lower confidence in fog development.

As the front passes Friday morning, precipitation chances rise to 40 to 60% in high elevations and 10 to 20% in lower elevations. Precipitation will remain generally north of Mountain Home, but snow levels will drop from 5,000 to 6,000 feet
