Friday was a quiet weather day for northern California, ahead of hotter and potentially more dangerous changes this weekend and early next week. A Red Flag Warning is in effect from Saturday evening through Monday morning. Tonight will be a quiet night for our area with some areas of smoke and high, thin clouds. Overnight lows will range from the 30s and 40s in the mountains to the 50s and lower 60s in the foothills and valley. Saturday will be a mostly sunny and breezy day with stronger wind developing late Saturday. Highs will begin their rapid warming trend, ranging from the upper 70s and mid 80s in the mountains, and from the lower 80s to near 90 degrees in the valley and foothills.
A strong ridge of high pressure will build over California and the rest of the West Coast this weekend and will persist through most to all of next week. We will have more sunshine, some areas of smoke, and more strong gusty wind Sunday and Monday. It is the wind, dry air and heat which are leading to the continuation of the Red Flag Warning through at least Monday morning. The wind will relax for the latter half of next week, but extra precautions need to be taken Saturday through Monday to ensure more fires don't begin in our area. Highs will rise for all areas through the middle of next week before modestly cooling late next week. Most highs will be in the 90s, with some lower 100s possible.
