A Wind Advisory has been issued for San Diego inland and mountain areas from 10 AM Tuesday until 12 PM Thursday. East winds 20-30 mph with gusts up to 50 mph will be strongest on Wednesday morning. The strongest winds will be in the foothills and adjacent valleys. The gusty winds can blow around unsecured objects.
THE WEEK AHEAD:
Surface high pressure is strengthening over the Great Basin. Offshore flow will start off in a more north to south direction, turning into a east to west orientation by Wednesday morning. Winds could gust around 60 mph in the more wind-prone locations. Offshore flow will be weaker Thursday and linger into Friday.
Temperatures will warm up through the week with temperatures peaking on Thursday. Very slightly cooler conditions Wednesday with the increased winds, but will catch up on the warming for Thursday. Afternoon highs will be 10-20 degrees above seasonal average Tuesday through Friday. Conditions will be different going into the weekend.
Low pressure troughing will come this weekend, leading to an end to the offshore flow and the return of onshore flow. Temperatures rapidly drop into the weekend, with nearly 20 degrees different from Friday into Sunday. The storm looks to impact the region Sunday into early Monday with rain.
