Alaskan Gulf Storm Expected to Hit Glendora

A cold storm bearing down on San Gabriel Valley is expected to bring rain to Glendora starting Monday night into Tuesday morning, according to the National Weather Service.

"There are two systems rotating around a long-wave trough," National Weather Service meteorologist James Thomas told in a phone interview Monday evening.  "It's the same system bringing cooler air from the Gulf of Alaska."

There remains a 70 percent chance of showers into Tuesday morning, according to the NWS forecast.

"We're going to see it steady Tuesday morning, with showers likely Tuesday afternoon and into the evening hours," Thomas said. "By tomorrow night, the second system will be coming in, Tuesday night into Wednesday, and rain should pick up again, maybe ending Wednesday evening."

Clearer skies are expected Thursday into Friday. Lows in the 40s and 50 and highs in the late 60s and early 70s are expected to continue through the weekend, with mostly clear skies on Saturday and morning clouds on Sunday.

Record lows were set around the southland, with the closest reported at UCLA. An early morning reading of 47 degrees beat UCLA's previous record of 48, a record set in 1953.
