Get ready for an even hotter day on the way for your Wednesday. A Heat Advisory is in place for the valley, foothills, and the Northern Mountains through 11pm Thursday night. Skies are mostly clear across Northern California this morning, but haze and smoke from wild fires will have an impact on air quality today. Many areas are starting the day with haze, but some of that will clear out after this morning. Temperatures have dipped into the mid 70's in the valley overnight, and into the 50's to 60's in the mountains. Winds are mostly light, and out of the Northeast this morning, but will be shifting to the Northwest this afternoon. Northwest winds are expected to be up to around 10mph this afternoon. Humidity is projected to dip into the 10 to 25 percent range later today, which is a bit lower than the last few days. We do still have a very slight threat of active weather in the mountains this afternoon, but the best chance will remain to our South today. High temperatures will range from around 106 to 111 degrees in the valley today, and from 95 to around 105 degrees in the mountains. The hotter temperatures, Northwest winds, and lower humidity will all combine to result in higher fire danger this afternoon.
The peak of the heat for this week is now projected to be on Thursday. Temperatures will end up a degree or two hotter than what is expected for this afternoon. That leaves the valley in the 107 to 112 degree range for your Thursday afternoon. You may want to plan your Thursday around staying indoors during the peak heat of the day. There is a very modest dip in temperatures on the way for your Friday. Most areas are expecting to top out around 3 degrees cooler than Thursday. That puts us in the 104 to 109 degree range for your Friday afternoon. Temperature will then stay in that same range through the weekend, leaving the region with temperatures that are well above average for this time of year. Please make sure to keep a close eye on loved ones during this stretch of hot weather. Heat related illness will be very possible over the next week.
