RIVERSIDE (CNS) – Temperatures will remain around average Friday, Sept. 25 in the Inland Empire, but a high-pressure system is expected to arrive on Sunday and bring hot weather along with an increased risk of wildfires next week, according to the National Weather Service.
An upper ridge will begin building in the region on Sunday and cause temperatures to rise through at least Tuesday, forecasters said. Gusty winds and low humidity are also expected in the mountains on Sunday and Monday, significantly raising the threat of wildfires.
High temperatures today could reach 104 degrees in the Coachella Valley, 95 in the San Gorgonio Pass near Banning, 91 in Riverside, 89 in Lake Elsinore, 87 in Temecula, 92 in Hemet and 79 in Idyllwild.
Highs in the Coachella Valley are expected to climb to 109 on Sunday, then 110 on Monday, forecasters said. In the Riverside metropolitan area, the mercury could reach 100 on Sunday, then 101 on Monday.
