SYNOP: (NWS SAN DIEGO)
Hot and dry inland through Monday. A shallow marine layer will keep coastal areas cooler with higher humidity. Isolated showers or thunderstorms are possible near the mountain crests and desert slopes this afternoon, mainly in San Diego and Riverside Counties. Any thunderstorms may produce gusty winds and isolate dry lightning. Seasonably dry weather with slightly below normal temperatures Tuesday through the end of next week.

There will be little change in the weather this weekend.

· Temperatures will remain in the 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.

· Winds will be light, except for westerly late afternoon and evening winds of 15 to 25 mph with gusts to 40 mph through the desert passes.

· Scattered showers and thunderstorms will form near the Colorado River this afternoon through Sunday morning.

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

· Minimum humidity will be mainly between 12% and 25% through the end of next week, except there will be widespread single digits and teens above and inland from the marine layer Monday.

· Westerly afternoon and evening winds of 20 to 30 mph with gusts to 50 mph will surface across the desert passes early next week and then decrease back to 15 to 25 mph with gusts to 40 mph Wednesday through the end of next week.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
A low grade monsoon pattern will continue this weekend with limited moisture and very hot conditions. Isolated thunderstorms should be confined to northwest Arizona and Lincoln County today. A weak West Coast trough will move inland Monday and bring a dry southwest flow back to our region with temperatures
trending down several degrees by mid week.

FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA

THERE COULD BE ISOLATED SHOWERS OR THUNDERSTORMS OVER THE MOUNTAINS THIS AFTERNOON AS SOUTHERN CALIFORNIA WILL BE AT THE WEST EDGE OF MONSOON MOISTURE. VERY LITTLE RAINFALL IS EXPECTED,MINIMIZING THE FLASH FLOOD THREAT. DRYING WILL OCCUR ON SUNDAY THROUGH THE WEEK, AND NO FLASH FLOODING IS EXPECTED.

Inland Empire
NONE NONE
San Bernardino County Mountains
NONE NONE
High Desert Including Apple and Lucerne Valleys NONE NONE
San Gorgonio Pass Near Banning NONE NONE

Flash Flood Codes: GREEN: NONE YELLOW: LOW ORANGE: MODERATE RED: HIGH

DAILY FUELS/FIRE POTENTIAL:
Above normal fuel moisture and below normal ERCs will keep the large fire threat low through the end of next week. Also, the absence of significant fire weather will keep the potential for large fire low through much of of next week. However, an increase in westerly afternoon winds along with very low humidity will increase the large fire threat on Monday. Expect light initial attack activity to continue across the area through the end of next week.
