RIVERSIDE (CNS) – The mercury will hit triple digits throughout the Inland Empire Thursday and through the week, with a heat advisory taking effect and prompting the National Weather Service to urge residents to take precautions.
“Temperatures over the interior will continue to trend upward Thursday, with the deserts and hotter valleys likely reaching/surpassing 100 degrees,” the NWS said in a statement Thursday.
The advisory takes effect at 10 a.m. and continues until 8 p.m. Sunday.
“Take extra precautions if you work or spend time outside,” the Weather Service stated. “Drink plenty of fluids, stay in an air-conditioned room and stay out of the sun.”
Temps are likely to be 5 to 10 degrees above average, forecasters said, noting that a ridge of high pressure stalled over Arizona will expand westward, displacing moisture and drying out inland Southern California.
Daytime highs in the Coachella Valley will hover around 115 degrees until the end of the week, with lows only dropping to the mid 80s, according to the NWS.
In the Riverside metropolitan area, the highs until Saturday will peak at or just over 100 degrees, with overnight lows around 65, while in the Temecula Valley, coastal breezes and marine layers will keep the mercury from exceeding 90 for most of the week, with lows falling to around 60, forecasters said.
