August 22, 2019
Summary: A trough of low pressure is currently moving into the interior west via the Pacific Northwest and northern California. This has somewhat increased the onshore flow, allowing a minimal amount of modified marine air into the valley. This will result in one more day of near average temperatures. There are two high centers out there. One is located over the Four Corners region of the Desert Southwest and the other off the Pacific coast. Models show the off shore high moving over California during the weekend, sending temperatures back into triple digits. Hotter locations by Friday will tease with the century mark with readings generally in the 100 to 105 degree range Saturday through Wednesday of next week.
Tropical storm Ivo will move up the Baja coast over the weekend then will turn into a subtropical low off the southern California coast Monday and off the central California coast Tuesday and Wednesday. it’s possible we could see some mid and high level clouds by the middle of next week, but no precipitation is expected other than some afternoon and evening thunderstorms over the high Sierra.
By Thursday and Friday of next week, a trough of low pressure will be moving into the Pacific Northwest, weakening the high and lowering temperatures back into double digits.
Forecast: Other than some high clouds today, it will be mostly clear with a slow warming trend through Sunday. Mostly clear and hot Sunday night through Tuesday. Mostly clear to occasionally partly cloudy Wednesday through Thursday and continued hot.

Two Week Outlook: August 29 through September 4: Above average temperatures can be expected during this time frame. There is indication on this model that we could see a visit from the monsoon or even the possibility of tropical moisture moving into at least southern California. The chance of rain will remain very low with the exception of the mountain areas. Nevertheless, eyes to the south would be wise as we move into the latter part of the month.
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 15 MPH through Sunday and mainly out of the northwest afternoons and evenings. During the later night and morning hours, winds will be generally at or less than 8 MPH with periods of near calm conditions.
Rain: Dry conditions will prevail for the next week and more than likely for at least the next 10 days. The only wild card, and it’s a small one, will be tropical storm Ivo which will move northwestward off the Baja, California coast over the weekend. This feature will turn into a subtropical low off the southern California coast Monday and will be off the central California coast Tuesday and Wednesday. the remnants of this low may move over the valley Wednesday or Thursday, but at this juncture it just appears we’ll see some mid and high clouds with the chance of thunderstorms over the high Sierra.
