June 2, 2021 Both Lemoore and Taft registered highs of 107 yesterday for tops in the valley.  Los Banos, on the other hand, had a high of 99.  That location benefited from some leaking modified marine air through Pacheco Pass.  The center of circulation of a strong dome of upper level high pressure will be…

June 1, 2021 All of the key signs are there for a heat wave which could easily match a mid summer episode.  Above the valley floor, the air mass is extremely warm.  Sandburg at an elevation of 4,100 feet was reporting a temperature of 74 degrees at 6 am.  Even way up at Bear Peak…

May 29, 2021 The marine layer at Monterey is roughly 2,700 feet deep.  Pressure is lower over the Desert Southwest than it is off shore.  This is allowing a shallow intrusion of marine air to move through the Delta and Pacheco Pass.  Currently, winds at the top of the dam at Pacheco Pass are sustained…

May 28, 2021 Currently, there is a weak trough of low pressure moving through the northern Rockies while a zone of weak upper level high pressure extends from off shore California into the Desert Southwest.  There is enough of an on shore flow to modify temperatures just a bit from Merced County northward.  Winds at…

May 27, 2021 We are  still being governed by weak features this morning.  a trough of low pressure is currently moving into the Pacific Northwest while a weak zone of upper level high pressure extends from the eastern Pacific Ocean into the Great Basin with a weak west/northwest flow aloft.  A very weak ripple of…

May 26, 2021 The overall weather pattern is still governed by weak features.  A weak trough of low pressure extends from Montana southwestward into southern California while weak upper level high pressure governs the eastern Pacific into northern California.  Satellite imagery shows high clouds moving into southern California on a weak southwesterly flow aloft with…

May 25, 2021 Tests are taking longer than expected. Reports will resume tomorrow morning, May 26. Thank you, John and Trudy

John is scheduled for a PET scan Tuesday morning, May 25.  We will issue a short report upon our return to the office.  Thank you for your continued patience.   May 24, 2021 This new week will be quite uneventful and will be governed by weak features.  For example, we currently have weak upper level…

May 22, 2021 Temperatures early this morning have dropped to 39 degrees at Lindsay, Orange Cove, and Sanger.  All other locations are in the low to mid 40s.  Temperatures will begin to head north again today as the center of circulation has now moved into central Nevada.  The freezing level this morning over Oakland is…
