June 10, 2022 A zone of upper level high pressure stretches from one center well off shore to another directly over California to yet a third high center over the Four Corners region. This will result in very hot weather this weekend although a bit of moderation will occur Sunday as a trough of low…

June 9, 2022 Upper level high pressure off the California coast will slowly link up with another high over the southern Plains, essentially developing a heat belt from Texas to California. Hot weather will begin today with readings over the century mark Friday through Sunday. I noted the temperature at 6:00am at Sandberg was 62…

June 8, 2022 low pressure just off the British Columbia coast is actually retrograding, meaning it’s moving northwestward into the Gulf of Alaska. This is allowing high pressure currently over the Desert Southwest to link up with another high off the southern California coast. This high is actually expanding northward now into the Pacific Northwest.…

June 7, 2022 The flow of modified marine air has ceased from moving down the valley as upper level high pressure slowly increases above California. Blended model information keeps the high at pretty much status quo through Wednesday with readings moving into the mid to upper 90s. The high will begin to expand further north…

  June 6, 2022 There is still a fairly steep pressure gradient between the coast and the interior west. The current altimeter reading at San Francisco is at 30.00 inches of mercury while at Las Vegas the reading is at 29.71. As a result, a fairly stiff northwesterly breeze is blowing down the valley. The…

June 4, 2022 At the upper levels of the atmosphere, there is a fairly robust low pressure system centered just west of Vancouver Island. The jet stream is flanked underneath the low and runs from west to east across the eastern Pacific and into northern California. Doppler radar is actually picking up virga from the…

June 3, 2022 The marine layer along the coast has now deepened enough to allow a shallow intrusion of modified sea breeze to move down the valley. The result will be a minor cooling trend. The cooling will be most pronounced today from Merced north as they have a nice air conditioning vent known to…

June 2, 2022 California is on  the far back side of upper level high pressure which is currently moving eastward into the middle of the country. A large low center is located several hundred miles off the Washington coast and is developing a trough southeastward into northern California. Mid 90s can be expected for one…

June 1, 2022 The marine layer has crept back towards the beaches this morning as upper level high pressure, which was off shore yesterday, will move overhead today. This will result in temperatures jumping from yesterday’s mid 80s to the mid 90s today. A trough of low pressure will stretch from off shore Washington down…

May 31, 2022 Today is the last day of meteorological spring. The month of May will go down as completely dry for the valley which pretty much caps off yet another dry year. Precipitation is around 60% to 65% of average at most locations. Meteorological summer begins tomorrow and, just as the calendar flips, temperatures…
