Deepening marine layer and fairly benign large scale pattern setting up for the next several days. Ample marine layer moisture aided by robust onshore flow will keep humidities high below about 2,000 to 2,500 feet. Otherwise continued dry above. Breezy W-NW winds each afternoon. ...Discussion from SFOFWFEKA... Warm and dry conditions continue this week. Afternoon RH remain low, into the teens or 20s, while overnight recoveries remain good in the valleys and moderate to good in the higher terrain. Afternoon northwesterly breezes of 15-20 mph are possible in the interior valleys today through Wednesday. Slightly stronger northwesterly winds are possible Wednesday to Friday, with gusts up to 25 mph possible in the valleys and gusts to 30-35 mph possible in the highest terrain. Late this week into the weekend, a ridge starts to build while an upper-level low is likely to form off the coast. Higher temperatures are forecast with triple digits possible in the valleys. If the upper-level low off the coast is positioned in a way to bring enough moisture into the area, convection is not out of the question with any thunderstorms likely to be dry. Confidence is low (less than 10%) at this time. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-250945- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 239 PM PDT Tue Jun 24 2025 Deepening marine layer and fairly benign large scale pattern setting up for the next several days.
