SYNOP: (NWS SAN DIEGO)
A fair and seasonal mid Summer weather pattern will persist this week with a shallow marine layer supporting higher humidity and low clouds over coastal areas, spreading into the western valleys at times. Gusty late day and overnight westerly winds will continue as well near the passes and on the desert slopes. It will be warmer through midweek with lower relative humidity inland as the marine layer shrinks back toward the coast, elevating fire weather conditions. Thursday and Friday, stronger westerly winds and low relative humidity may result in critical fire weather for several hours each day on the desert slopes. Cooler again next weekend.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Dry conditions expected today and Monday with generally light afternoon breezes. Warming temperatures are likely Tuesday through Thursday, rising several degrees above normal. Cooler air returns late week through the weekend with gusty winds in the afternoons and a return to more elevated fire risk.

* Formation chance through 48 hours…low…30 percent.

* Formation chance through 5 days…low…30 percent.

Showers and thunderstorms located a few hundred miles south-southwest of the southern tip of the Baja California Peninsula are associated with a trough of low pressure. Development of this system is no longer expected.

* Formation chance through 48 hours…low…0 percent.

* Formation chance through 5 days…low…0 percent.
