==============================================================================
SYNOP: (NWS SAN DIEGO)
High pressure will continue the hottest weather through Monday. A shallow marine layer will keep coastal areas cooler with higher humidity. Southwest California will be on the western edge of monsoonal moisture through Saturday. Isolated showers or thunderstorms are possible near the east slopes of the mountains late this afternoon and again late Saturday afternoon. Any thunderstorms may produce gusty winds and a few dry lightning strikes, but not much rainfall. A weak trough of low pressure near the West Coast will spread slow cooling inland for Tuesday through Thursday of next week.

Maximum temperatures will be around 5 degrees above normal away from the coast through this weekend, with upper 70s and 80s across the mountains and 90s to 104 in the valleys.

· Minimum humidity will remain mainly between 12% and 25% away from the coastal areas through Saturday.

· Westerly winds of 15 to 25 mph with gusts to 40 mph will surface across the desert passes during the late afternoons and evenings through this weekend. Otherwise, winds will be less than 15 mph.

· Isolated afternoon showers and thunderstorms will be possible over the Sierra Crest today and near the Colorado River Saturday.

· A cooling trend will occur Monday through the middle of next week and then there will be little change in temperature late next week.

· Temperatures will be 5 to 10 degrees below normal Wednesday through the end of next week.

· Minimum humidity will be mainly in the single digits across the deserts and across the mountains of Southern California Sunday through the end of next week.

· Westerly winds of 20 to 30 mph with gusts to 50 mph will surface across the desert passes Monday through the end of next week.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Mid level moisture combined with a weak disturbance brushing northwest Arizona could help enhance mainly dry thunderstorm development across the higher terrain of Mohave County again today. Elsewhere across southern Nevada and southeast California, there will be increased cloud cover but fairly stable conditions. A weak West Coast trough will return Sunday into next week and bring a dry southwest flow back to our region with temperatures lowering a few degrees.

FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA
THERE COULD BE ISOLATED SHOWERS OR THUNDERSTORMS OVER THE MOUNTAINS THIS AFTERNOON AND SATURDAY AFTERNOON AS SOUTHERN CALIFORNIA WILL BE AT THE WEST EDGE OF MONSOONAL MOISTURE. VERY LITTLE RAINFALL IS EXPECTED.

SPECIAL NOTES:

DAILY FUELS/FIRE POTENTIAL:
The potential for large fire will be low through the end of next week due to the absence of excessive heat, strong winds, and abundant lightning away from the deserts. Fuel moisture will be near to above normal and ERCs will be near to below normal away from the deserts through the end of next week. Expect light initial attack activity across the region through the end of next week.

TROPICAL EAST PACIFIC REPORT:
For the eastern North Pacific…east of 140 degrees west longitude:

Showers and thunderstorms associated with a tropical wave a few hundred miles south of the southwestern coast of Mexico have become slightly better organized since yesterday. Some development of this
system is possible during the next day or so before environmental conditions become less conducive over the weekend while the wave moves to the west-northwest at 10 to 15 mph.

* Formation chance through 48 hours…low…20 percent.

* Formation chance through 5 days…low…20 percent.

A tropical wave located about 1600 miles southwest of the southern tip of the Baja California peninsula is producing disorganized cloudiness and showers. Development, if any, of this system should be slow to occur over the next couple of days while the wave moves westward at 10 to 15 mph.
