Rain, thunderstorms could roll through

Sub-tropical moisture moved over San Diego County on Sunday, bringing a small amount of rain to the mountains and some inland valleys, and the pattern could continue Monday, a National Weather Service meteorologist said Sunday.

Thunderstorms could bring more rain, some locally heavy, on Monday, followed by drier weather, said Don Whitlow of the NWS.

“It’ll warm up a little more toward the end of the week,” Whitlow said.

He said the warming could send high temperatures into the low 90s in inland valley communities like El Cajon and Escondido, a rarity in what has so far been a cool summer.

Sunday, coastal temperatures remained in the high 60s or very low 70s, while it was mainly in the high 70s inland, according to the NWS.

While precipitation was reported as close as Lakeside and near Escondido, the only measurable amounts fell in far northeastern San Diego County.

About .05 inch of an rain fell in Palm Canyon near Borrego Springs, .02 inch to the north in Coyote Creek, and .01 inch was recorded in Oak Grove, according to the Weather Service.
