Get ready for intense heat to return for the remainder of your work week across Northern California. High pressure is buidling Westward from the 4 corners region over the next few days and will be the dominant impact on our forecast through Friday. An Excessive Heat Warning has been issued by the National Weather Service out of Sacramento for our entire valley and foothill areas from 11am this morning through 10pm Friday night. Skies are clear for the start of your Wednesday and we'll be staying sunny for the foreseeable future. Temperatures are starting out a little warmer this morning. Valley areas have dipped into the high 60's to low 70's this morning, and mountain areas are starting out in the 40's to 50's early today. Winds will be out of the North to around 10mph and humidity is expected to dip into the 10 to 25 percent range this afternoon. High temperatures are projected to end up in the 104 to 108 degree range in the valley today and mountain areas will mostly end up in the low to mid 90's this afternoon. The hot and dry weather will result in high fire danger in our region today. The good news is that winds are expected to stay on the lighter side, which should prevent a Fire Weather Watch or Red Flag Warning from being issued.
The peak of the heat is expected on Thursday, with temperatures climbing into the 105 to 110 degree range in the valley. Heat related illness will be a major concern over the next few days. You're advised to stay hydrated, avoid outdoor activities if you can, and to dress in loose fitting and light colored clothing. We'll be staying very toasty on Friday, but temperatures are projected to drop by 2 or so degrees compared to Thursday. A modest cooling trend will then return for your weekend, but we'll still be hot on Saturday. Valley highs are projected to end up in the mid 90's to low triple digits on Saturday afternoon. A more substantial drop in temperatures will be on tap for Sunday, with valley highs projected to top out in the low to mid 90's to end your weekend. We'll be staying sunny and dry through your extended forecast. High temperatures will climb back into the mid to high 90's towards the middle of next week.
