Through Tuesday, San Diego will be cloudy with a risk of precipitation due to a thick marine layer. Later this week, the cool and overcast weather will give way to warmth and sunshine.
A thick, obstinate marine layer contributed to the’meh’ Monday in San Diego. Even though there was a brief period of partial clearing in the afternoon, the vast majority of cities west of the mountains were covered in significant amounts of cloud throughout the day. The depth of the marine layer will be helped by a low pressure area over the west. As it lingers, be prepared for the possibility of spotty precipitation and inland fog.
Tuesday’s chances of the marine layer lifting are modest, but conditions should be similar to Monday’s, with the potential for Tuesday afternoon sunshine. Tuesday’s temperatures will continue below seasonal levels as the storm system over the West that was discussed earlier pushes additional cool air our way. Tomorrow, the cooler air will momentarily reduce the desert’s heat.
As a longwave trough moves south, pressure gradients are starting to constrict. Through midweek, we will contend with an increase in wind speed in addition to morning clouds. Up until early Wednesday morning, the mountains and desert of San Diego County are under a Wind Advisory. Up to 60 mph gusts are anticipated.
This week, there are predicted to be two significant wind occurrences. The first one took place from Monday night through Tuesday, and the second one will occur from Tuesday through Wednesday. Even areas to the west will experience an increase in these events, while the strongest winds will be noted in mountain and desert microclimates. You can see in the chart below how the county will experience a rise on Monday and Tuesday, especially. The highlands and deserts will experience gusts that can reach 60 mph.
MICROCLIMATE FORECAST FOR TUESDAY:
ALONG THE COAST:
Through Tuesday, the surf will continue to be 2 to 4 feet high with a moderate risk of rip currents. By the middle of the week, the height of the waves will rise. On Wednesday, expect rip currents with a high risk and surf heights between 3 and 5 feet.
A ridge of high pressure causes a gradual clearing and a lowering of winds, which ushers in changes from Thursday through the weekend. Beginning on Thursday, the ridge will significantly increase afternoon high temperatures as well. The 8-Day Forecast down below will show you that change. Particularly on Saturday, daytime highs will reach a peak 5 to 10 degrees above normal.
