San Diego, CA – A major weather transition is approaching the San Diego area, with temperatures expected to plunge from Friday’s forecast high near 95 degrees to approximately 70 degrees by Wednesday, Oct. 21, when showers become likely. The 25-degree decline will develop over several days, replacing unusually hot conditions with cooler, potentially wetter weather.

Friday’s expected high near 95 degrees falls to approximately 90 Saturday, 86 Sunday and 80 Monday. By Tuesday, temperatures should reach only about 71 degrees, followed by 70 Wednesday and 68 Thursday…
