Oregon wakes under a muted sky this morning as cool, gray air settles across the Rogue Valley. Pavement glistens from overnight moisture, and low clouds cling to the hills outside Medford—a quiet December setup that hints at fog pockets forming again through the morning. The air feels crisp but still, and early travelers may notice visibility shifting from clear stretches to hazy, milky layers near open fields.

According to the National Weather Service, patchy fog remains possible before mid-morning, especially around Medford, Central Point, and stretches of Highway 62. Drivers should expect quick visibility drops in shaded valleys and prepare for damp roads. Use headlights early and allow extra distance in slower-moving areas.

Once fog lifts, sun returns with highs near 57° today and 58° Saturday, offering a brief window of mild December weather. To be fair, conditions stay calm for most of the weekend, but meteorologists are now tracking an approaching Pacific moisture push expected to reach southern Oregon late Sunday into Monday. Models show a “winter tease” setup—clouds thickening Sunday afternoon, followed by a slight chance of showers Monday and more widespread rain Tuesday through Thursday.

No snow concerns appear for the Rogue Valley at this time, though colder air in the Cascades will support mixed precipitation at higher elevations next week. Still, December transitions can shift quickly; any clearer early-morning skies may allow surface frost in outlying areas.

Plan errands or outdoor decorating earlier in the day for the best visibility. Fog may re-form late tonight and again Saturday night before the wetter pattern arrives.

Sunday: Patchy fog early, high 56°, clouds increase.
