SYNOP: (NWS SAN DIEGO)
Dry weather is expected to persist through much of next week with high temperatures fluctuating a few degrees around average. Slow cooling into Saturday, slow warming for Sunday through Tuesday, then a little cooler for Wednesday through Friday. A marine layer fluctuating around 1500 feet deep will keep areas near the coast cooler with higher humidity. Inland humidity will remain lower.

Gusty southwest to west winds in the mountains and deserts during the late afternoon into the evening will be a little stronger for today and Saturday.

Highs through the weekend running 2-5 degrees below normal with readings in the 70s at the coast and in the mountains to the upper 80s to lower 90s in the valleys. By next Monday and Tuesday, highs will return to the upper 90s to 103 in the valleys.

· Minimum RH will generally be in the teens the next few days with fair to good recovery at night.

· Local north winds of 20-30 mph with gusts to 40 mph will be possible in Santa Barbara County during the evening into the overnight hours the next few days. Some stronger gusts may occur Saturday night into Sunday morning.

· Persistent west winds of 20-30 mph with gusts to 40 mph through the Kern County Mountains, Antelope Valley, Banning Pass and points eastward in the high desert this weekend.

· No thunderstorms through the period.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Monsoonal moisture moves out of our area today, though residual moisture could result in isolated showers and thunderstorms this afternoon in Mohave County. As drier air moves in, fire weather concern increases, particularly with localized breezy conditions.
The most elevated risk looks to be in northern Lincoln County where maximum wind gusts range between 25 and 30 kts. Sunny, dry conditions will prevail through the remainder of the forecast period with RH values in the single digits. Wind speeds at for the moment remain below fire weather criteria, though we will continue to monitor for updates.

DAILY FUELS/FIRE POTENTIAL:
After a significant outbreak of lightning Wednesday and yesterday’s sparse lightning coverage, there may be some holdover fire activity in the upper elevations of the Sierras eastward into the Inyo National Forest. The highest concentration of lightning may have been over the northern Inyo National Forest the past two days which may be the focus of resource demand through the weekend. The weather will generally be unsupportive of large fire growth, but breezy weather in the Kern County Mountains and in Santa Barbara County may allow for rapid rates of spread despite higher than average RH. Next week, expect ignition components to rise substantially due to sunny and warmer weather. Resource demand may be moderate today and Saturday if holdover fires are detected over Central CA, otherwise expect light demand through the period. Out of region demand continues to accelerate due to gusty winds and lightning over the Pac. Northwest and Great Basin

============================================================
THIS DAY IN WEATHER HISTORY:
2018: High sea surface temperatures (SSTs) peaked at the La Jolla Scripps buoy, reaching an all-time maximum of 79.5F, approximately 10 degrees above normal for the date and the highest ever SST measurement from any Southern California buoy. Numerous other buoys reported temperatures above 78F. Although SSTs peaked on this day, they remained well above normal for several months during the summer. Minimum temperatures were much higher than normal at the coast, and it was exceptionally muggy.

2005: A Mesoscale Convective System (MCS) swept into the region from Nevada, bringing thunderstorms to the region for a 21st consecutive day. The thunderstorms associated with the MCS rolled through the deserts from San Bernardino to San Diego County, causing flash flooding that resulted in 12 swift water rescues. They also produced severe winds that downed trees and whipped up a dust storm with near zero visibility in the Coachella Valley
2000: Dense fog over the coastal waters caused a lone boater, en route from Oceanside to San Diego on a 24 foot sailboat to become disoriented. After spending two days lost at sea she was forced to call the Coast Guard on this day. Her vessel was located 40 miles south of Point Loma using Navy prototype radio signal direction finder equipment

1998: The remnants of Tropical Storm Frank produced showers and thunderstorms from the coast to the deserts. Thunderstorms in the Inland Empire produced severe downburst winds that downed trees in tore a 90 ft section of roof from a hotel in Riverside.

1989: One of the most severe convective outbreaks of record in Southern California began on 8/7 and continued until 8/11, when it climaxed. On this day a thunderstorm unloaded torrential rains on Yuma, AZ with 5.82 inches of rain in 24 hours, a new record for the state (remarkably the normally driest part of the state) and double the annual average. Up to 1000 homes were flooded with water to five feet deep. On this day a thunderstorm dropped 0.75 inch hail on Desert Hot Springs and over one inch in Idyllwild. More than a half inch fell on Palm Springs on 8/10.

1941: A heavy thunderstorm struck Needles. Flash floods and debris flows damaged streets and highways. Several motorists were stranded, but no one was hurt.

1936: A tropical cyclone tracked north northwestward across the Gulf of California with the remnants tracking northward into western Arizona. Locally heavy rainfall occurred in the mountains surrounding LA.
==================================================================

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

Showers and thunderstorms associated with a broad area of low pressure located near the Gulf of Tehuantepec have become a little more concentrated overnight. Conditions are forecast to be
conducive for some additional development over the weekend and a tropical depression could form within the next few days while the system moves west-northwestward at 10 to 15 mph, just off the southwestern coast of Mexico. Regardless of development, this system could product locally heavy rainfall along portions of the
southern and southwestern coast of Mexico during the next couple of days.

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

* Formation chance through 5 days…medium…50 percent.

An area of low pressure is forecast to develop several hundred miles southwest of the southern tip of the Baja California peninsula by early next week. Environmental conditions are expected to gradually become more conducive for development through the middle of next week while the system moves westward or west-northwestward at 10 to 15 mph.

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

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