Warmer temps this weekend, then a “heatwave’ next week. A heatwave in March! Yes. We are looking at 20° – 25° above normal, as high pressure moves over CA and NV. So expect early Summer heat for sure. As we go into the last week of March, forecast models show the ridge starting to weaken. More updates Friday…DMATT
