August 5, 2019
Summary: Hottest temperatures in the valley yesterday, according to ag stations, were 104 at both east Porterville and Sanger, 105 at Rio Bravo, and 106 at east Clovis. California remains on the western edge of strong upper level high pressure centered over the Four Corners region of the Desert Southwest. The marine layer along the coast remains fairly shallow. The latest sounding at Monterey gives a depth of 1,200 feet. Satellite imagery shows considerable amounts of high clouds from the monsoon embedded within a southerly flow aloft which may dim the sun from time to time. Even so, triple digits can be expected through Tuesday. At that time, a low center currently west of Washington, will slowly drift southward to a position off the southern Oregon coast by Thursday. The high over the Four Corners region will drift into the southern plains. All of this means the winds aloft by Wednesday will be out of the southwest. By Thursday and Friday, the proximity of the low off the Oregon coast will cause the marine layer to deepen, allowing that all important modified sea breeze to move down the valley. By Friday, temperatures north of Kern County could actually dip into the low 90s with mid 90s in Kern County. Temperatures will remain in that range through Sunday. By Monday, the high will again become reestablished over the Four Corners region, shutting down the marine machine with warmer temperatures. However, excessive heat is not on the horizon. Even though we’re getting high level moisture from the monsoon, no precipitation over our region is expected.
Forecast: A mix of high clouds and sunshine today. Mostly clear tonight through Wednesday with periods of high clouds at times. Mostly clear Wednesday night through Monday and considerably cooler.

Two Week Outlook: August 12 through August18: 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 mainly out of the northwest at 5 to 15 MPH afternoons and evenings with local gusts to near 20 possible. Winds during the night and morning hours will be generally less than 10 MPH with periods of near calm conditions.
Rain: Expect dry conditions for the next week to ten days.
