Temperatures are forecast to peak into the 100s for many interior valley locations Sunday. Relative humidity will be dry in the mid teens with moderate RH recovery overnight. An approaching low pressure system will slightly cool temperatures and pull moisture across the area early next week. This system will increase chances of thunderstorms over the interior Monday and Tuesday, with the highest chances of storms in Trinity and interior Humboldt counties during the peak of the afternoon Monday. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-300545- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 1044 AM PDT Sun Jun 29 2025 The marine layer has pulled back to the coast which will allow for another seasonably warm and dry day across the district.
