KEY MESSAGES
* Today-Wednesday:
- Temperatures begin a cooling trend today and Wednesday to near normal temperatures, with below normal temperatures expected Wednesday in areas adjacent to the Delta.
- Smoke will continue to impact areas in the vicinity of the Green Fire, though more southerly winds this evening and on Wednesday should keep most smoke out of the Valley during the day.
- Locally breezy northerly flow in the northern/central Sacramento Valley and adjacent terrain which may allow smoke from the Green Fire into the Valley, mainly in the overnight through morning timeframe.
- Onshore flow and Delta Breeze influence expected through the weekend, bringing minor cooling and overnight relief to the Delta and adjacent Valley.
- Breezy to gusty southerly winds expected this evening, especially in the vicinity of the Delta.
- Probability of gusts 30 mph or greater this evening: - 20 to 50% in the central and northern Sacramento Valley - 60 to 95% in the Delta and vicinity - Humidities improve slightly throughout this week, especially closer to the Delta.
