RIVERSIDE (CNS) – Winter weather will close out the week, with a rainstorm forecast to sweep across the Inland Empire Friday night into Saturday morning.

“Rainfall is expected … across Southern California, with higher rainfall totals in portions of Orange, Riverside and San Bernardino counties,” the National Weather Service said in a statement. “The most widespread precipitation is expected Friday evening through overnight.”

Forecasters said a trough of low pressure originating from the Pacific Northwest will roll into the region, blanketing the area with widespread rainfall, though the heaviest downpours are expected between the early evening and midnight hours Friday.

“Snow levels will be very high with this system, above 9,000 feet,” the weather service said. “All the precipitation that occurs in the mountains will fall as rain.”

The lack of freezing precipitation is likely to be welcome relief to residents of the mountain communities along Highway 243 in the San Bernardino National Forest, where cold storms in recent weeks increased snowpacks to the point that some roads were impassable.

Although most of the communities south of the San Gorgonio Pass and west of Palm Springs have dug out, residents of a few hamlets in the San Bernardino Mountains to the north remain buried.

Meteorologists said precipitation in the Riverside metropolitan area will be anywhere from a quarter to a half inch, while Riverside County locations closer to the mountains could receive up to an inch.

“Rainfall will end on Saturday morning, with dry and warmer days in store Sunday and Monday, as high pressure aloft pushes into the western states,” the NWS stated.

Daytime temperatures in Riverside metro on Thursday will be near 70 degrees, while on Friday, the mercury will settle just below 60, with lows around 50 Thursday and Friday nights.

In the Coachella Valley, temperatures will top out in the low to mid- 70s Thursday and Friday, with lows in the mid-50s, while in the Temecula Valley, temps will peak in the upper 60s on Thursday and the upper 50s on Friday, with lows in the mid to upper 40s, according to the NWS.

Expected rainfall from rainstorm in Riverside County March 10, 2023.
