Midweek will turn wet throughout the Inland Empire, as a storm system ushers in low intensity rainfall, none of which is expected to trigger flooding.

According to the National Weather Service, a Pacific storm will make landfall Tuesday night, and the atmospheric river will generate the highest precipitation rates Wednesday, tapering off and being replaced by a weaker system Thursday and Friday.

Mountain areas could receive as much as four inches of precipitation, with snow levels above 9,000 feet Wednesday and lowering to 5,000 feet later in the week as a colder trough of low pressure grazes the region, forecasters said.

“The high deserts will see a decent amount of rain, with .5-.75 inches through Wednesday afternoon. Farther south, the rain amounts will be much lower,” according to a weather service statement.

The Riverside metropolitan area is likely to receive about one-third of an inch Wednesday, while Lake Elsinore could get about a half-inch, and Coachella Valley communities may see trace amounts of rain, according to meteorologists.

The Riverside County Emergency Management Department was monitoring the weather system, but officials were not anticipating the need for cautionary advisories in locations around the Temescal Valley and Lake Elsinore that are prone to flooding, mud and debris flows from the burn-scarred Cleveland National Forest.

The Riverside County Flood Control & Water Conservation District is still digging out and repairing culverts, washes and canals overwhelmed by tons of mud and debris during the damaging Feb. 14 storm, which prompted the Board of Supervisors to declare a local emergency.

According to the weather service, the trough that will glance the Inland Empire Thursday and Friday will not pack significant rain potential, but temperatures will dip slightly below their seasonal averages.

The high in Riverside Friday is predicted to top out at 58 degrees, while the mercury in Palm Springs will plateau at 62, according to the Weather Service.
