Rain expected as storm Blanca passes through SoCal

The NWS says temperatures Monday will surpass 100 degrees in some locations. But on Tuesday, a low-pressure system will bring moisture into SoCal.

As moisture from tropical storm Blanca rolls into SoCal, forecasters predict a 20 percent chance of showers and isolated thunderstorms in Los Angeles and Ventura counties Tuesday afternoon.

"Then on Wednesday, the low shifts a little bit farther East and takes a slight chance of storm activity off to just the mountains and deserts," said Stuart Seto, weather specialist with the National Weather Service.

Seto said humidity will increase near the mountains Tuesday. The showers and possible thunderstorms will likely pass by Thursday, he said. 

California started the week with a spring heat spell on Monday with temperatures surpassing 100 degrees in some locations from the inland valleys and deserts of Southern California to the inland parts of the San Francisco Bay Area.

Warming will extend to the coastline in some areas, with highs reaching into the 80s Tuesday.

Temperatures will cool down but stay slightly above normal this week and next, said Seto. Expect temperatures to reach the mid-70s in downtown Los Angeles and the 80s throughout the valleys.

"Next week, we got high pressure returning so temperatures will be warming up again — so get ready for summer time," said Seto.
