June 6, 2020
Summary: The low pressure system which resulted in a few light showers has accelerated eastward only to be replaced by a strong trough of low pressure currently centered off the coast of the Pacific Northwest. A big trough extends southward into California. Temperatures will continue to tumble today and Sunday. In fact, readings are already anywhere from 9 to 16 degrees cooler than 24 hours ago.
There’s a great deal of wind energy in the mid and upper levels of the atmosphere. That, combined with a 13 millibar difference in pressure between San Francisco and Las Vegas will result in a continuation of gusty winds down the valley through Sunday. There is also a 5 millibar difference in pressure just between Salinas and Fresno. It’s rare to see temperatures only in the mid 70s this time of year, but that’s what we’re expecting Sunday as the coolest air aloft arrives and couples with a valley pooled with cooler marine air.
No precipitation is expected from this point on with the possible exception of the high Sierra. A flat zone of upper level high pressure will stretch across the eastern Pacific beginning Monday and into California, lasting through Thursday. This will maintain a dry westerly flow aloft and will bring about a significant warming trend. Mid to upper 90s are anticipated by midweek, however excessively hot temperatures are not expected at this time.
Models continue to show another trough of low pressure moving into the western U.S. beginning Friday for the next round of cooler weather.
Forecast: Mostly clear to occasionally partly cloudy through Sunday evening. Expect breezy and much cooler conditions. Mostly clear Sunday night through Thursday with a warming trend. Mostly clear Thursday night through Saturday with a cooling trend.
