944 FNUS56 KEKA 151837 FWFEKA FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA NATIONAL WEATHER SERVICE Eureka CA 1137 AM PDT Sun Jun 15 2025 ...Locally elevated fire weather conditions expected Monday and Tuesday afternoons and evenings in Zone 264... .DISCUSSION...Warmer inland temperatures today. An approaching shortwave trough is bringing some weak elevated instability and moisture this afternoon. Moisture is lacking, but a low chance (up to 5%) exits for isolated dry thunderstorms this afternoon and evening for mainly Humboldt and Del Norte counties as this feature interacts with the higher terrain. Colder cloud tops and a cumulus field are observed on satellite over Humboldt and Del Norte counties this afternoon. Trinity County has a brief chance this afternoon and a second chance in far NE portions of the county Monday afternoon for an isolated thunderstorm as the trough axis passes. Northerly winds are increasing in southern Mendocino and Lake County this afternoon. These winds will further increase Monday afternoon over the interior ridges, mainly in southern Mendocino and Lake counties. These mainly diurnally- driven afternoon winds will trend slightly lower Tuesday, but will increase again late next week with a stronger trough and front. Minimum RH values will trend lower early to mid next week, with some values in the mid to upper teens Wednesday. Locally elevated to some brief critical fire weather conditions will develop with these afternoon wind pulses and lowering RH.
