SAN DIEGO — The sunshine was back this afternoon! This led to warmer temperatures for most of the county as daytime highs were mainly in the 70s. Today was likely the warmest day of the week.
Yesterday, it was 70 degrees in June at the San Diego International Airport, and only the third day since the start of May to make it to 70 degrees. Thursday brought a report performance.
But of course, those marine layer clouds will start to roll back in tonight. We will kick off our Friday with the marine layer. A weak area of high pressure has moved in as the low lifts. This will give our atmosphere another chance to dry out by the afternoon hours and lead to more hours of sunshine.
Temperature-wise, we will stay below seasonal due to the push of the cool, marine air and the returning marine layer. Despite temperatures peaking in widespread 70s on Thursday and again Friday, expect daytime highs will remain cooler than usual for this time of the year (2 to 10 degrees).
SEASONAL (AVERAGE) HIGHS:
- Coast near 71 degrees
- Inland valleys near 81 degrees
- Mountains near 76 degrees
- Desert near 101 degrees
The onshore breeze, we have felt for much of the week, will remain intact through Saturday. It will be a breeze, west of the mountains, mainly in the teens. The stronger winds will continue to impact the mountains and the desert with sustained westerly winds shifting from 20 - 30 mph and gust peaking 40 - 55 mph.
AT THE COAST:
A south swell generated high surf that was still lingering Thursday. The surf was up to six feet, highest north of Carlsbad through Orange County. The surf will start to subside by Friday. Expect the surf to be two to four feet with a moderate risk of rip currents at our local beaches.
The afternoon sunshine expected on Friday will be short-lived.
Another area of low pressure looks to move in over the weekend. This will reinforce a stubborn marine layer, below seasonal temperatures (10 to 15 degrees inland), and a westerly breeze with stronger gusts in the mountains and desert.
As of this evening's model runs, rain chances will bump up over the weekend, mainly north of us. There is a chance for rain and a few thunderstorms favoring San Bernardino County mountains.
Locally, there is a slim chance in our mountains, but light rain cannot be entirely ruled out on Sunday. West of the mountains, we could see patchy drizzle and showers with a deepening of the marine layer Friday night through Saturday morning and a repeat performance Saturday night through Sunday morning.
