Idaho, USA – A quiet, gray dawn settles across Boise as low clouds drift over damp pavement and faint halos glow around streetlights. The air feels still and cool, and patchy fog already curls through the Treasure Valley, hinting at slower starts for early Thanksgiving travelers.
According to the National Weather Service in Boise, areas of fog expand around sunrise today, especially along I-84 between Nampa and Boise. Visibility may drop quickly, so drivers should slow down early and use low beams rather than brights. Light rain lingers in some pockets, adding a wet sheen to roads and parking lots. Residents heading out for school runs or early shopping should expect cautious travel until conditions lift later in the morning.
According to meteorologists, the calm air continues tonight as another round of patchy fog forms after midnight and stretches into Tuesday morning. This setup brings a classic late-fall pattern: mild afternoons, chilly mornings, and a steady transition toward a broader November shift. Models hint at a Winter Tease by midweek, with a weak disturbance sliding north and introducing a slight rain chance Wednesday. Any precipitation stays light, but the timing matters for those beginning Thanksgiving trips.
According to Idaho Transportation Department officials, fog remains the primary concern through midweek. The agency urges drivers to allow extra space on I-84, especially through Meridian and east Boise, where dense fog often clings to the valley floor. Shoppers and commuters should plan flexible schedules when fog advisories appear.
A calmer pattern emerges into the weekend. Sunshine mixes with crisp late-fall air on Friday and Saturday, offering ideal conditions for early holiday decorating, yard cleanup, or short regional drives. After all, November can pivot fast, and another system may build early next week.
