A storm system rolling into the Inland Empire will produce rain and moderate snowfall at higher elevations Thursday afternoon, according to the National Weather Service.
Forecasters said the trough of low pressure sliding into the region from the northwest will spread wet weather throughout Southern California, though intensity levels will vary.
“Showers will develop (Wednesday) night and continue into Thursday afternoon, with showers ending from the northwest early Thursday evening,” the NWS stated. “Rainfall will range from one-tenth to one-quarter inch near the coast, to one-half to one-inch in the mountains. Less than one-tenth is expected in the deserts.”
Freezing levels will generally hold around 6,500 feet but could dip lower overnight, meteorologists said. A few inches of snow may fall in the mountain communities within and around the San Bernardino National Forest.
Forecasters warned that “gusty southwest to west winds” were likely in mountains and passes as the storm front traverses the area mostly into Thursday morning.
The system will exit the region by Thursday evening, followed by an immediate drying out going into the weekend, according to the NWS.
However, another storm system gaining energy in the Gulf of Alaska is predicted to envelope most of California by Monday night, according to NWS prognostication charts. The trough may generate moderate to heavy precipitation in the Inland Empire, but forecast models had not yet indicated potential accumulations.
The highs in the Riverside metropolitan area will top out in the upper 50s, with lows near 40. In the Coachella Valley, temperatures will peak in the low 60s, with lows in the upper 40s, while in the Temecula Valley, highs will reach the mid-50s, with lows in the upper 30s, according to the NWS.
