Dry air with some moderate wind continues above the marine layer, with RH as low as 10-20% at some inland sites above 2,000 feet. Despite the dry air aloft, the wind direction remains onshore through the week, preventing critical fire weather conditions. A small disturbance may deepen the marine layer a bit on Monday before weak ridging returns. A more robust system will bring strong onshore winds to the coast next weekend. ...Discussion from SFOFWFEKA... 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. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-161000- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 254 PM PDT Sun Jun 15 2025 Dry air with some moderate wind continues above the marine layer, with RH as low as 10-20% at some inland sites above 2,000 feet.
