AM frost gives way to afternoon showers Monday
SAN DIEGO (CNS) – Very cold weather and frost are expected in parts of San Diego County early Monday ahead of rain this afternoon.
A National Weather Service frost advisory for the valleys and deserts is scheduled to expire at 8 a.m. today. Forecasters said the advisory applied to far inland valleys and lower deserts "where little wind and clear skies will allow temperatures to fall rapidly,” possibly to below freezing.
Overnight temperatures were expected to fall to between 28 and 34 degrees. Forecasters urged residents to cover sensitive outdoor vegetation and bring pets inside. Mostly sunny conditions are expected in San Diego County later this morning, but an approaching trough of low pressure will bring cloudy skies and rain this afternoon and tonight, according to the weather service.
Showers and thunderstorms are likely in most areas other than the desert later today, and a slight chance of thunderstorms and mountain snowfall is in the forecast for tonight.
It will be mostly sunny throughout the majority of San Diego County Monday morning as a trough of low pressure will bring light rain and mountain snow in the afternoon and a chance of thunderstorms in areas other than the deserts Monday night.
High temperatures today will be:
- Around 59 degrees at the beaches
- Around 58 in the western valleys
- 48 to 53 near the foothills
- 57 to 62 in the mountains
- Around 66 in the deserts.
