Summary: Strong upper level high pressure is centered over Arizona this morning and continues to cause mid and high level moisture to rotate in from the south via the monsoon. Doppler radar shows isolated showers over southern California and it is possible isolated thunderstorms could break out over the summit of the Sierra Nevada this afternoon and again Wednesday afternoon.
The proximity of the high means triple digits will continue today then a southward movement of the thermometer will begin Wednesday as the high over the Desert Southwest begins to shift eastward, eventually ending up over Texas by Friday.
In the meantime, a low center located several hundred miles off the coast of northern Oregon and Washington will drift slowly east/southeast and will move into southern Oregon and northern California Friday and Saturday. no rain will be associated with this low as it moves inland, but cooler air will move in aloft. A strong onshore flow will develop with a rapidly deepening marine layer for a major cooling trend Thursday through Saturday. it’s possible, especially north of Kern County, that some locations may not even reach the 90 degree mark.
By Sunday, the low will have moved into the northern Rockies and weakened while upper level high pressure begins to become reestablished over the Desert Southwest. It will connect with another high center well off the southern California coast. Triple digits may revisit the valley by Tuesday of next week.
Medium range models show nothing unusual as the summertime high remains over the Desert Southwest with low pressure off the coast of the Pacific Northwest.
Forecast: Mostly clear but variable high clouds will mix in from time to time through Wednesday. continued hot today with a slow cooling trend beginning Thursday. Mostly clear Thursday through Saturday and cooler. Mostly clear Saturday night through Tuesday with a warming trend.

Two Week Outlook: August 13 through August19: this model actually shows much of the U.S. enjoying below average temperatures. The exception is the western one-third where temperatures will be marginally above average. No precipitation is expected at this time.
August: This model projects fairly persistent upper level high pressure over the Desert Southwest. The monsoon shows up, as it typically does this time of year, but it generally produces little to no precipitation over the valley. The bottom line, temperatures will be marginally above average with typically dry conditions.
August, September, October: The 90 day outlook doesn’t really give strong indicators one way or the other. As far as precipitation is concerned, this model is projecting near average totals for the next three months. This model also projects above average temperatures for much of the western U.S.
Winds: Winds will be generally at or less than 12 MPH today and less than 8 MPH tonight. Winds Wednesday will be mainly out of the northwest at 5 to 15 MPH with locally stronger gusts, mainly along the west side. Winds Thursday through Friday will be out of the northwest at 10 to 20 MPH at times with local gusts to 30 MPH possible along the west side, especially along the Interstate 5 corridor.
Rain: Expect dry conditions for the next week to ten days.
