Eureka, CA – The North Coast woke under a silvery chill this morning as a Frost Advisory remains in effect until 9 a.m. Temperatures across coastal Humboldt County hover near 36°F, coating rooftops and car windshields in thin ice as the region prepares for the Thanksgiving travel rush.
According to the National Weather Service, calm winds and clear early skies have allowed cold air to settle in overnight, setting the stage for one of the coldest mornings of the month. Drivers should use caution on shaded roads or bridges where patchy frost may linger through mid-morning.
By midday, the chill eases under partly sunny skies, with highs reaching 57°F. Thanksgiving Day brings milder air and a 30% chance of light rain developing after 4 p.m. — enough to dampen travel plans along Highway 101 and coastal routes north toward Crescent City.
Showers may continue into Thursday night, followed by drier, mostly cloudy weather Friday and Saturday. Afternoon highs remain in the upper 50s through the weekend with light winds. Though no major storm systems are forecast locally, forecasters are tracking a powerful Arctic front expected to drop south across the U.S. beginning December 1. That system could unleash heavy snow and blizzard conditions across northern and central states, potentially complicating post-holiday travel nationwide.
For now, North Coast residents can expect cool mornings, light rain chances, and manageable travel conditions — a crisp, quiet stretch before winter’s first real push arrives.
5-Day Outlook for Eureka:
- Wednesday: Mostly sunny, high 57°F
- Thursday (Thanksgiving): Chance of showers, high 59°F
- Friday: Mostly cloudy, high 58°F
- Saturday: Partly sunny, high 56°F
- Sunday: Mostly sunny, high 57°F
