Sunny and mild Thursday ahead of a cloudier, showery end of the week | San Diego Local Forecast

A comfortable Thursday, but a trough of low pressure will bring chance for light rain & mountain snow with gusty winds and much cooler temperatures.

SAN DIEGO — A weak ridge of high pressure moved over us on Wednesday. It will linger through Thursday with mild temperatures, dry conditions and a mostly sunny sky. Thursday afternoon will lead to another day of mild temperatures, mostly in the 70s, along with sunshine and a light breeze. Overall it's a very comfortable day, but a precursor to what's expected to come starting on Friday.

A cold low pressure system will create a dip in the jet stream and close in on Southern California Friday. The wind will start to pick up on Thursday evening with the strongest wind gusts expected in the mountains and the desert. Rain chances will also increase on Friday with that day being the more favorable one for wet weather.

As of Wednesday evening, the best window for scattered rain will be on Friday morning. We are still looking at chances for wet weather throughout the rest of Friday with spotty showers possible through Saturday. 

The cold nature of this system shows a chance for snowfall in our local mountains. It would be light, but we could see up to an inch above 4,500 feet.

The low will start to make its exit on Saturday leaving a dry and cooler air mass behind. We will dry out by the second half of the weekend. On Sunday morning, patchy frost will be a hazard for the inland valleys with overnight temperatures in the 30s in spots. 

A ridge of high pressure will strengthen over us on Tuesday and Wednesday and lead to warmer temperatures that will be near to slight above seasonal midweek.
