SAN DIEGO — THE WEEK AHEAD:
A ridge of high pressure will remain over the region through Saturday. The ridge will suppress the marine layer, creating a chance for morning fog over the coastal areas.
A deep trough of low pressure will dig south into California late Sunday into Monday. Temperatures will drop to near seasonal average by Tuesday. There is still some uncertainty after Tuesday, because models are not agreeing on a solution, but temperatures may remain near average through the remainder of next week.
