Dry and warmer weather is likely to continue through Tuesday afternoon in most parts of San Diego County, according to the National Weather Service.
The marine layer will gradually become more and more shallow early this week with low clouds and fog sticking closer to the coast and western coastal valleys.
High temperatures Tuesday are expected to be 66 to 70 near the coast, 71 inland, 71 to 76 in the western valleys, 67 to 77 in the mountains and 91 to 95 in the deserts, NWS said.
Beyond that, development of a very strong upper-level low pressure system will cause a quick bout of offshore winds Wednesday. This occurrence will drop temperatures in the deserts by a few degrees, while areas west of the mountains will persist with warmer weather.
Another gradual warming trend looks likely heading into this weekend, with no precipitation in the foreseeable future, according to meteorologists.
