July 29, 2019
Summary: Some of the more noteworthy high temperatures yesterday were as follows: Arvin, Maricopa, and Bakersfield all hit 110 followed closely by Sherwood and east Clovis at 109. All other locations were between 105 and 108.
Today will be hot but not quite as hot as yesterday as the strong upper high which 24 hours ago was centered over southern California has shifted to the east into Arizona. By midweek, it will be over Colorado and New Mexico.
Meanwhile, a weak trough of low pressure has established itself over the Pacific Northwest with the southern portion of this trough digging southward into northern California. These features this time of year are typically very weak and this one is no exception. However, a push of modified marine air is already pushing through the Delta and this could lower temperatures into the mid to upper 90s north of Merced County. The central and south valley will still endure one more day of triple digits with the hottest readings coming out of Kern County.
The combination of slightly lower pressures aloft and shallow intrusion of marine air into the valley will lower temperatures into the upper 90s Tuesday and all the way through Saturday. In other words, readings will be close to seasonal averages.
The winds aloft this week will be out of the southwest, keeping the monsoon south of central California. One surge of monsoonal moisture will effect southeast California Tuesday and Wednesday, but these southwesterlies aloft will shear this moisture eastward before it has a chance to move much further north.
This will begin to change during the second half of the coming weekend. Models are consistent in showing the high shifting back towards the west. The clockwise flow around the high will again turn the winds aloft out of the south, favoring more monsoonal moisture moving into central California by Monday. Hot conditions will also return next week as we once again find ourselves on the western side of high pressure over the Desert Southwest.
Forecast: Other than occasional high clouds, it will be mostly clear and not quite as hot through Friday mostly clear Saturday through Monday and becoming hot again Monday.

Two Week Outlook: August 5 through August11: Overall, upper level high pressure remains anchored over the Desert Southwest with an active monsoon moving into the Desert Southwest, the Great Basin and the Sierra Nevada. There’s always a slight chance of sprinkles during the monsoon season, but overall, temperatures will remain dry with above average temperatures.
July: July, of course, is typically hot and if this model has any credence, it will be hotter than average. With a dominant Four Corners high and a trough over the middle of the country, usual July dry conditions will prevail.
July, August, September: This model is indicating that the western U.S., including California, will experience above average temperatures overall during the mid to late summer period. Precipitation is expected to be near average, which, of course, is very little and there’s no reason to believe otherwise.
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.
