May 5, 2022 The northern portion of the ridge of upper level high pressure which has driven temperatures into the lower 90s is breaking down. We should see one more day of lower 90s before a significant cooling trend begins Friday. Already this morning, the marine layer has deepened and is moving through the Delta.…

May 4, 2022 Relatively strong upper level high pressure will be right above California during the next 48 hours. At the surface, there is a very weak off shore flow, just enough to combine for a very warm day as readings trend upwards to around 12 degrees above average. This puts most locations in the…

April 28, 2022 A dry trough of low pressure is currently moving through California. Surface pressures are falling ahead of the trough over the Great Basin and are rising off shore. This will cause winds to crank up over the Kern County mountains and deserts. Even on the valley floor, the difference in pressure between…

April 27, 2022 We will continue to be under a quiet weather pattern in central California, although some increase in wind conditions will arrive tonight and Thursday due to the passage of a weak trough of low pressure. This will also lead to a marginal cooling trend as temperatures drop back into the mid 70s…
