A fast-moving storm front will churn up winds and produce scattered rain across the Inland Empire Thursday, abruptly followed by a Santa Ana wind event, according to the National Weather Service.
The agency issued a Wind Advisory from 10 a.m. Thursday to 6 a.m. Friday, predicting winds ranging from 30 to 40 mph, with gusts to 55 mph in some locations.
According to the Weather Service, a trough of low pressure will sweep into the region from the Gulf of Alaska Wednesday night and Thursday morning, dragging moisture with it, though not in copious amounts.
“It will have enough available moisture to generate a few showers,” according to the NWS. “Behind the trough, the winds quickly shift offshore.”
There’s a 30% chance of precipitation in the Riverside metropolitan area Thursday.
Santa Ana conditions will ensue as the low is replaced by a ridge of high pressure settling over the Great Basin in Nevada and Utah, according to prognostication charts published by the NWS.
The ridge will hold in place into the weekend, when it gives way to another low, but no precipitation is in the forecast again until Tuesday.
High temperatures in the Riverside metropolitan area are expected to be in the mid 60s Thursday, with lows in the mid 40s. Highs will top out in the upper 70s Friday to Sunday, with lows in the upper 40s, forecasters said.
In the Coachella Valley, highs will be in the low 70s Thursday, and the mercury will steadily rise, with highs in the low to mid 80s Friday to Sunday, and lows in the mid 50s. In the Temecula Valley, temperatures will peak in the low 60s Thursday, with highs in the low to mid 70s Friday to Sunday, and lows in the mid 40s, according to the Weather Service.
