A cool and wet closeout
The end of April will see a marine layer bringing clouds and a drop in temperatures.
A cool, wet weather pattern is developing across Southern California, with a deep marine layer bringing clouds and a drop in temperatures that will persist through the week.
“We’re going to have well below normal temperatures over the next couple of days,” said Ariel Cohen, a meteorologist for the National Weather Service in Oxnard. “It will be pretty cool ... quite chilly to close out April.”
In general, the highs through at least Wednesday are expected to be five to 10 degrees below seasonal averages, Cohen said.
Along the coast, temperatures will probably remain in the 50s. Inland valleys will top out in the 60s, while in the mountains, highs could stay in the 40s.
This weather pattern will bring sporadic precipitation to the region, but if an area receives rain — and many places won’t, Cohen said — totals for the week aren’t expected to surpass one-tenth of an inch.
“We’re not looking for any serious rain,” Cohen said.
There will be “patchy drizzle, on and off ” through at least Wednesday and possibly into Thursday, driven by that marine layer.
There will be a slight chance for showers Thursday through Saturday — offshoots from a stream of storms that will mostly take aim farther east, the meteorologist said.
“We’ll be getting — at most — a couple of light showers, but the real impacts will be over the Great
Plains of the U.S.,” Cohen said. “Most areas [in Southern California] probably won’t be getting a whole lot of anything.”
The National Weather Service’s Climate Prediction Center has forecast that below-average temperatures are likely to persist in Southern California through at least May 1, with a chance for precipitation that’s slightly above average.
The long-range forecast for May doesn’t show atypical temperatures or rainfall. High temperatures are forecast to creep back up, and rain should become infrequent.
