SYNOP: (NWS SAN DIEGO)
Fair and mild weather will continue today with areas of fog this morning and again tonight and Sunday morning. For Sunday into Monday, low pressure from the north will bring much cooler weather, gusty onshore flow and rain and mountain snow showers. A period of strong north to northeast winds is possible Monday night through Tuesday night as the storm system moves east. A northwest flow pattern will prevail for the remainder of the week with near normal temperatures, and another chance of light precipitation Friday and next Saturday.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
The area will enjoy dry and mild weather today before a low pressure system drops down from the north Sunday and over San Diego Sunday night and Monday bringing cooler temperatures, gusty north winds and scattered rain showers and snow showers. The best potential for precipitation will be south of I-40 Monday. The system will move away Tuesday leaving a dry pattern much of the rest of the week.
