It already started heating up in northern California this afternoon, and much hotter weather is coming our way in the short term. Excessive Heat Warnings go into effect Friday afternoon. Be sure to stay cool and stay safe! High pressure is in control of our weather pattern at this time and it won't be loosening its grip anytime soon. Tonight will be clear and mild with lows in the 50s in the mountains, 60s and 70s in the foothills and valley. Friday will be mostly sunny to sunny and hotter. Highs will range from the 90s in the mountains and foothills to the 100s and lower 110s in the valley.
Saturday and Sunday should be the hottest days for our region, and records will be threatened. We will have dangerous heat in virtually all parts of northern California, so please make sure your kids and pets are same, check on seniors to be sure they're staying cool, drink plenty of water, seek the shade and air conditioning, and do what you can in the morning when it is cooler. We can expect a gradual cooling of our weather from Monday through next week, but it will still be hotter than average a week from now, and lows will not cool very well, leading to little relief at night, either.
