August 25, 2020
Summary: The pattern we will be under this week is quite typical of late summer. Strong upper level high pressure continues to bake the Desert Southwest and interior southern California while a weak trough of low pressure lingers off the northern and central California coast. As is so often the case, we will be between these two forces of nature. The marine layer is roughly 1,800 feet deep at Fort Ord. the sea breeze is moving through the Delta as winds at Travis Air Force Base are out of the southwest at 21 MPH. However, winds further south at Pacheco Pass are dead calm. Some cooling will be noted over the northern San Joaquin Valley, however the central and south valley will remain in the upper 90s.
The monsoon continues to move into the Desert Southwest, however the winds aloft sandwiched between the southwestern high and that weak trough to our northwest will keep winds out of the south/southwest, causing the monsoon to tilt away from central California. Some models show a stronger trough moving into northern California about Tuesday of next week, however most continue to keep us sandwiched between those two main features.
Forecast: Mostly clear skies through Friday night. Mostly clear Saturday through Tuesday.

Two Week Outlook: August 31 through September 6: This model indicates a dominant ridge of high pressure will be along the west coast for, what else, above average temperatures. The flow aloft is projected to be mainly southwesterly for dry conditions.
September: This model is indicating basically the western half of the United States will have above average temperatures, continuing the trend of the summer season into the early fall. This model shows near average precipitation, which is minimal at best anyway.
September, October, November: This model always indicates above average temperatures for the western U.S. and this time around is no exception. As we head into the autumn season this model is indicating there will be equal chances of above or below precipitation.
Winds Discussion: Winds through Friday will be mainly out of the northwest at 5 to 12 MPH afternoons and evenings and 3 to 6 MPH nights and early mornings with periods of near calm conditions.
Rain Discussion: Expect dry conditions for the next 7 to 10 days.
Afternoon Dew Points Today: Low to mid 60s. Kern: Upper 50s to the lower 60s.
