September 1, 2020
Summary: The marine layer along the coast allowed temperatures from Merced County north to remain in the mid 90s yesterday. The depth of the marine layer at Fort Ord is now roughly 2,000 feet. However, there is no strong push of sea breeze into the valley at this hour. Winds at Travis Air Force Base in the Delta are sustained at just 14 MPH. further south, through Pacheco Pass, winds are just 4 MPH, so readings, especially from Fresno County south, will be nearing the century mark each day through Thursday.
A strong high is located off the coast of the Pacific Northwest. It’s projected to slide down over California Thursday and Friday. The high will shift a bit further east over Nevada by Saturday as a big ridge builds up into the Pacific Northwest. This pattern will be custom made for a late summer heat wave, even though today is the first day of meteorological fall. The Labor Day weekend will be a sizzler as some models indicate readings will push the 110 degree mark, pushing temperatures into record territory. The high will also block any moisture from the monsoon from moving into California.
A very amplified pattern will begin Sunday as a large high covers the western U.S. for much of next week. Locations east of the Rockies will be enjoying well below average temperatures as Canadian air sweeps southward. In other words, the unrelentless summer of 2020 is like the pandemic: it just doesn’t seem to want to quit.
Forecast: Clear skies through Thursday night. Clear and hot Friday through Tuesday.
