We had more beautiful, seasonable late July weather for northern California on the second-to-last day of July, but our fire danger continues. A Red Flag Warning is in effect for Siskiyou and Modoc counties through Friday night due to gusty wind, hot highs, and dry air and fuels. Tonight will be a mostly clear to clear night with mild, seasonable lows ranging from the 40s and 50s in the mountains to the 60s and lower 70s in the foothills and valley. Friday will be a hot and breezy end to the month of July with seasonable temperatures continuing. Highs will range from the 80s and lower 90s in the mountains, and will range from the 90s to the lower 100s in the foothills and valley.
Several small disturbances will move toward northern California over the next seven days, but all we expect from those areas of low pressure are a few more clouds and stronger breezes at times. By late next week a deeper trough of low pressure from the Pacific Ocean will move toward the West Coast, and that will push the dominant ridge of high pressure currently over the western United States further to the east. That will bring a little more substantial cooling to our weather but it will only be slightly below average. Lows will remain seasonably mild, while highs will range from the 80s in the mountains to the 90s and lower 100s for the valley with a cooling trend.
