Another chance of precipitation will arrive across the Inland Empire Friday through Sunday, though the amounts may be quite light, according to the National Weather Service.
The agency said that troughs of low pressure curving south from the North Pacific will lead to an increase in moisture and opportunities for rainfall.
NWS forecasters said the pattern shift will lead to a “weak atmospheric river” rolling over Southern California, with the earliest chance of precipitation sometime Friday afternoon.
“There is still quite a bit of spread in rainfall amounts,” the Weather Service stated. “Periods of showers are expected through the weekend into early next week as troughs line up to periodically pass the U.S. West Coast.”
Current trends show less than a half inch of rain likely in most locations through the weekend.
Meteorologists said winds will pick up noticeably with the passing of each trough, but the greatest gusts will be within the passes and around the mountains. Highest speeds will be 55 mph.
Above average temperatures will hold until Friday, when the inclement weather arrives.
For the Riverside metropolitan area, highs Tuesday to Thursday will be in the low to mid 80s, with overnight temperatures in the mid 50s. Friday to Sunday, the daytime mercury will peak at or just below 70, with lows in the low 50s.
In the Coachella Valley, upper 80s to low 90s will be the norm Tuesday to Thursday, dropping to the mid 60s at night, while Friday to Sunday, the temperature band will be low 80s to upper 50s.
The Temecula Valley’s temp range will roughly approximate the Riverside area’s, forecasters said.
