What the forecast actually says

Area Forecast Discussions are the real forecasts, written 3 to 4 times daily by NWS meteorologists reading the models and interpreting what they mean for your area. They offer far deeper insight than any weather app, but they're written in dense meteorological shorthand. Plaincast uses Anthropic's Claude to summarize them into plain English, side by side with the annotated original.

Moderate risk for sneaker waves along the Lost Coast and Mendocino Coast through Wednesday.
Elevated fire danger through Tuesday for interior areas due to breezy afternoon winds.
Near to slightly below normal interior temperatures expected through the middle of next week.
Coastal stratus likely to form each night and clear each afternoon through at least the middle of next week.
Hot interior temperatures likely late next week.
Near to slightly below normal temperatures likely for the interior areas, while near to slightly above normal coastal temperatures are likely for the coastal areas for the coming days. Breezy afternoon winds elevate fire danger in eastern Trinity, eastern Mendocino, and Lake counties. Hot interior temperatures return late next week.
The weak marine inversion and light nearshore winds allowed coastal temperatures to remain above normal with the immediate coast observing mid 60s to low 70s, and tying a record at Weather Forecast Office EKA on Woodly Island. Winds offshore slightly increase and turn more northerly, which could knock coastal temperatures back towards normal (low to mid 60s); however, the weak marine inversion remains in place through mid next week. The Mendocino Coast will see breezier afternoon winds which will support closer to normal temperatures.
The troughing pattern has also brought breezy afternoon winds of 20 to 25 mph in the interior areas, mainly in the higher elevations and channeled terrain (such as Clear Lake and the Trinity River valley). Low afternoon relative humidities in Trinity, eastern Mendocino, and Lake Counties along with these winds brings an elevated fire weather threat.
There is high confidence in high pressure rebuilding over the area late next week. the blend-of-models forecast is showing moderate to high probabilities for high temperatures in the triple digits for most interior valleys Friday into the weekend. JB/JJW
