==============================================================================
SYNOP: (NWS SAN DIEGO)
High pressure will bring hot weather into next week except near the coast and in the higher elevations of the mountains. Southwest California will be on the western edge of monsoonal moisture for Friday through Sunday. There is a slight chance for thunderstorms with dry lightning in the mountains for Friday and Saturday afternoons. The marine layer will become shallower, to around 1200 feet, by the weekend into early next week. High pressure may weaken for the middle of next week with some cooling.

Maximum temperatures will be a little above normal away from the coastal areas through this weekend, with upper 70s and 80s across the mountains and 90s to 102 in the valleys.

· Minimum humidity will be mainly between 12% and 25% away from the coastal areas through this weekend.

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

· Isolated afternoon showers and thunderstorms will be possible near the Colorado River Saturday.

· Temperatures will cool a few degrees each day Monday through the middle of next week.

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

· Westerly afternoon and evening winds of 20 to 30 mph with gusts to 50 mph will surface across the mountain ridges and desert passes Monday through the middle of next week.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
The weather pattern will be more summerlike through the weekend as high pressure builds over the Four Corners region. This will result in hotter temperatures area wide and thunderstorm chances mainly in northwest Arizona.

CHANGES SINCE PREVIOUS BRIEFING
The Red Flag Warning remains in effect for today over western Arizona due to a risk for dry lightning. Continued moderate confidence that dry thunderstorms will develop this afternoon, with the best chance in northern Mohave County.

CONFIDENCE AND DETAILS
Mojave Desert & Southern Great Basin
HIGH Confidence
Prolonged exposure to heat can result in heat exhaustion or heat stroke.
Dehydration, hyperthermia, and heat cramps could affect those who do not take precautions.
Hot temperatures may increase heat-related emergency calls.

Details:
Today – Sunday Forecast High Temperatures:
Kingman, Owens Valley, Beatty, Rachel: 99-103
Las Vegas, Pahrump, Barstow, Morongo Basin: 106-109
Mesquite, Overton, Logandale: 108-112
Colorado River Valley from Hoover Dam to Lake Havasu City: 111-115
Death Valley (Furnace Creek): 119-122

Mohave County
MODERATE Confidence Isolated dry thunderstorms could produce lightning strikes which start fires and erratic, gusty winds which accelerate fire spread.

Details:
Red Flag Warning Today
Arizona Fire Weather Zone 102
Potential for dry lightning combined with low relative humidity values and cured fuels will result in dangerous fire weather conditions; especially across the Arizona Strip.

Strong wind gusts near thunderstorms may also aggravate the fire danger.

FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA
SOUTHWEST CALIFORNIA WILL BE IN THE WESTERN EDGE OF MONSOONAL
MOISTURE FOR FRIDAY THROUGH SUNDAY. THERE COULD BE A FEW SHOWERS
OR THUNDERSTORMS NEAR THE MOUNTAINS FOR FRIDAY AND SATURDAY
AFTERNOONS. NOT MUCH RAINFALL IS EXPECTED.
THURSDAY FRIDAY
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:
The potential for large fire will increase some through the weekend as temperatures become a little above normal. However, the large fire threat will not become elevated since humidity will stay above critical levels and winds will be light away from the deserts. Expect initial attack activity to increase a little through this weekend, but it will remain on the light side. The large fire threat and IA activity will decrease a little Monday through the middle of next week as temperatures cool.
