Aside from smoke from our area fires, we've had a much clearer day over northern California with the monsoonal clouds moving away. We can expect slightly cooler weather Wednesday, with another warming trend ahead. The monsoon moisture which was transported overhead late Sunday and Monday has been driven back into Nevada, leaving our region with a clearing sky along with smoke from our current fires. Tonight will be clear and mild with lows from the upper 40s and 50s in the mountains to the 60s and lower 70s in the foothills and valley. Wednesday will be bright and seasonable with some areas of smoke. Highs will range from the 80s and 90s in the mountains to the 90s and lower 100s in the foothills and valley.
Northern California will remain between a trough of low pressure off the West Coast and a ridge of high pressure over the Great Basin through the end of the workweek, which will provide fairly seasonable weather and plentiful sunshine. The ridge will begin pushing westward toward California late this week and this weekend, which will gradually warm our highs to a few degrees above average. Another chance of monsoonal moisture being moved around that high toward our region next week, but at this time little to no rain is in the forecast. We will get more clouds by early next week, however. Valley lows will remain in the 60s and lower 70s. Valley highs will range from the upper 90s to the lower 100s, peaking this weekend.
