It will be warm and dry again Monday in San Diego County, but the National Weather Service forecasts a “big change” on Tuesday.
“We will continue to see very warm conditions today, but a big change is on the way” the weather service advised. “A cold low pressure system from the northwest will bring much cooler and windier conditions on Tuesday along with a chance of showers.”
The change in weather will begin with a cooling onshore breeze and possible morning fog.
Highs on Monday will be 70 to 75 near the coast, 76 to 81 inland, 78 to 83 in the valleys, 69 to 75 in the mountains and 83 to 88 in the deserts.
The coolest day of this week was predicted to be Tuesday, when high temperatures could be 5 to 10 degrees below average. Gusty west winds were expected over the mountains, deserts, and coastal waters, forecasters said.
There was a slight chance of rain and mountain snow on Tuesday.
Accumulations look mostly light, a tenth of an inch or less west of the mountains, with no accumulation expected in the desert. Given the inside track of the low pressure system, winds will be the main impact of this system.
West to northwest winds were expected to strengthen Monday evening through Tuesday over the ocean waters with gusts potentially reaching 25 to 30 knots. The winds were likely to produce rough seas that will be hazardous to small craft.
At county beaches, a short-period wind swell was expected to produce periods of elevated surf late Tuesday through Wednesday, mainly on west-facing beaches. Increased risks for rip currents were likely to accompany the surf.
Dry conditions with a gradual warming trend were predicted for Wednesday through the end of the week.
