A Red Flag Warning is active across the valley and foothills right now, and is set to stay in place through 5pm Tuesday. The biggest concerns that prompted the Red Flag Warning are above average temperatures, gusty North winds, and very low humidity. We are starting out with clear skies, breezy North winds, and low humidity for the start of your Monday. Temperatures have dipped into the 50's to mid 60's overnight in the valley and in to the 30's to 40's in most mountain areas. Winds are out of the Northeast to 10mph early today, but will be picking up out of the North this afternoon. Sustained winds will likely reach 15mph out of the North, and there will be potential for gusts up to around 30mph. Humidity has not recovered well overnight, with some parts of the valley under 30 percent this morning. Humidity could dip to as low as 5 percent this afternoon, which is dangerously dry. Temperatures are projected to climb into the low to mid 90's in the valley this afternoon, and into the high 70's to mid 80's in the foothills and mountains. The low humidity could lead to fires starting very easily, while the strong winds could push any active fires to spread rapidly.
The Red Flag Warning is set to continue on Tuesday. Most of the conditions will stay similar to Monday, but temperatures are projected to be a couple of degrees warmer. Most areas of the valley will be in the mid 90's on Tuesday afternoon. The warming trend will continue into Wednesday, but the Red Flag Warning is set to expire at 5pm Tuesday. Wednesday looks likely to be the hottest day of your extended forecast, with high temperatures reaching mid 90's to low triple digits in the valley. Similar conditions will persist on Thursday, but we will likely see a degree or two drop from Wednesday.
A cooling trend is expected to take hold of Northern California on Friday and will ramp up this weekend. High temperatures will drop back down into the high 80's to low 90's on Friday in the valley and further cooling is expected for the weekend. High temperatures are currently projected to end up in the mid to high 70's on both days this weekend, and there will be a chance for showers across the Northern 3rd of our area. Cooler temperatures look like they will persist into next week, and the potential for showers will continue.
