In Santa Rosa Valley and, more broadly, across the state of California: Clear skies are expected this morning, with temperatures rising quickly into the very hot range, reaching between 68 and 99 degrees Fahrenheit by midday. Winds from the northwest will be moderate, with speeds up to 15 mph and gusts reaching 32 mph, providing some relief from the heat. No precipitation is anticipated throughout the day, so outdoor plans can proceed without concern for rain. As the afternoon progresses, temperatures are likely to remain high, with the hot conditions persisting into the evening. It’s important to stay hydrated and take precautions against the heat, especially during the peak afternoon hours. The wind may help keep the air feeling slightly cooler, but the high temperatures could still pose a risk of heat-related issues.
