Summary: A shallow intrusion of marine air moved down the valley overnight. Temperatures as of 6:00am were generally 4 to 6 degrees cooler than 24 hours ago. Dew points are anywhere from 8 to 15 degrees lower. It will definitely be a bit more comfortable today than we’ve seen in a while. The latest sounding at Fort Ord indicates the depth of the marine layer is just about 2,000 feet.
In the broad picture, strong upper level high pressure remains over the Desert Southwest and southern California where the relentless heat of the summer will continue for two more days. Northern and central California will be the benefactors of a weak trough of low pressure. In all likelihood, areas especially north of Kern County, will see readings no higher than the mid 90s which is just about average for late August.
The weak trough currently overhead will weaken as we move into the weekend for a minor warming trend.
Looking ahead to next week, some models show an elongated high building from Oregon and across northern California and into Nevada. By the middle of next week, if this pattern does set up, widespread triple digits will make their triumphant return.
In the tropics, we will have to watch two brand new named storms. Tropical storm Isele and tropical storm Hernan are each projected to be near somewhere around the southern tip of Baja beginning Saturday. for now, it appears any moisture from these storms will remain to our south, however it is something to keep an eye on.
Forecast: Mostly clear skies through Sunday night. Mostly clear Monday through Thursday.

Two Week Outlook: September 2 through September 8: 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 Sunday 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: Mid to upper 50s. Kern: Low to mid 50s.
