Rain goes away but frost expected at night

SAN DIEGO COUNTY - Weather experts say chilly weather and patchy frost are in store in San Diego County tonight, Dec. 31, but no more rain or snow was expected, according to the National Weather Service.

Forecasters expected areas of frost over parts of the deserts and in wind-sheltered valleys tonight along with low nighttime temperatures through Wednesday,

NWS meteorologist Tina Stall said chilly temperatures, with lows in the 30s, could stick around for the next few nights, but "as we get toward the weekend, it may warm up a little bit."

Additional rain and snowfall were not expected, she said.

"It looks looks like the precipitation is pretty much done for probably at least the rest of the work week, probably through the weekend as well," Stall said.

However, lingering snow from the passing winter storm could cause icy road conditions.

"If you get any melt during the day it could re-freeze again at night, causing areas of black ice, so roads can still be slick," Stall said.

The California Highway Patrol reported that around 6:40 p.m. Sunday, Dec. 30, Sunrise Highway was completely iced over near state Route 79. It was later closed on the north end.

The county's Department of Public Works had snow plow crews that worked through the night to clear the roads, but icy conditions remained in some mountain areas.

Snow gates were open on Sunrise Highway about 11:30 a.m., but chains were still required, according to the DPW.
