SYNOPSIS: A deepening marine layer will return along the coast with patchy drizzle. King tides combined with tidal anomaly will continue to bring the threat of coastal flooding in low-lying areas around Humboldt Bay today. A series of frontal systems moving north of the area will bring a chance of light rain orsprinkles across the northern portion of the area through the weekend, especially for Del Norte and Humboldt counties.
King Tides from December 3rd to the 7th may lead to minor coastal flooding in low-lying areas mainly around Humboldt Bay.
TODAY:
Inland: Patchy fog before 10am. Otherwise, mostly sunny, with a high near 63. Calm wind becoming north northwest 5 to 8 mph in the morning.
Along the Coast: A slight chance of drizzle after 10am. Mostly sunny, with a high near 58. North northwest wind around 8 mph.
TONIGHT:

Extended Forecast: Weather systems moving from the north will bring light rain chances to the northernmost counties (Del Norte and Humboldt) through the weekend, while southern areas stay mostly dry. Early next week, high pressure is expected to rebuild over the region. However, there’s significant uncertainty in the forecast – weather models show an even split between drier conditions and light daily rain (0.10-0.25 inches) continuing Monday through Wednesday, mainly affecting the North Coast.
