NATIONAL WEATHER SERVICE REPORT

SYNOPSIS: Another hot and dry day expected today for the interior. There is a slight chance for dry thunderstorms in Del Norte County this afternoon and evening. Stratus likely to remain persistent on the coast. Sunday night into Monday there is a chance for a wetting rain in the northern portion of the area and interior highs down into the 70s.

TODAY: 

Inland: Sunny, with a high near 90. Calm wind becoming south southwest 5 to 9 mph in the afternoon.

Along the Coast: Patchy fog before 8am. Otherwise, partly sunny, with a high near 63. West southwest wind 5 to 7 mph.

TONIGHT:  

Inland: Partly cloudy, with a low around 54. South wind 5 to 7 mph becoming calm in the evening. 

Along the Coast: Patchy drizzle after 11pm. Patchy fog. Otherwise, mostly cloudy, with a low around 56. West wind around 5 mph becoming calm in the evening.

Extended Forecast: A low-pressure system offshore is slowly shifting toward the Pacific Northwest, which will help deepen the marine layer and keep the coast cloudy and cooler, while the inland areas remain warmer. There’s a small chance of isolated thunderstorms this afternoon and evening, especially in parts of Siskiyou and Del Norte Counties, though rain chances remain low for now. By late Thursday into Friday, drizzle or light coastal rain becomes possible, with a slight chance of pockets of heavier showers. Looking ahead to Sunday night into Monday, a stronger system could bring more widespread rainfall, especially to Del Norte, Humboldt, and Trinity Counties, with a good chance for meaningful totals there.
