December 4, 2021 Low clouds and fog, which gained a firm foothold in the lower Sacramento and northern San Joaquin Valleys the past few mornings spread southward overnight. They have now reached the base of the Tehachapi Mountains. Every location between Delano and Sacramento is reporting ¼ mile visibility or less. Since the fog developed…

December 4, 2021 There is quite a bit of fog north of Visalia. In fact, Visalia, Madera, and Merced were all reporting a visibility of ¼ mile or less. Ground fog is also widespread over the northern San Joaquin/lower Sacramento Valley. There is a weak upper low off the southern California coast. It’s a dry…

December 2, 2021 Strong upper level  high pressure extends from the eastern  Pacific across California to a second high over the Great Basin. At the surface, high pressure remains centered over Utah, generating a weak off shore flow. There are two  low centers. One us just off the southern California coast while the second is…

December 1, 2021 Temperatures will be pushing record values today and Thursday. A strong ridge of upper level high pressure covers the eastern Pacific and extends through California and into the Great Basin. The balloon sounding over both Oakland and Vandenberg indicated an easterly flow from ground level through 30,000 feet. A rather stiff pressure…

At the surface, high pressure is centered over southern Idaho, maintaining an off shore flow. The current altimeter reading at Boise, Idaho is 30.36 inches of mercury…

November 29, 2021 The valley floor has essentially dried out due to the long period of dry weather. Hanford received .07 back on November 8th while Bakersfield picked up .01. So despite the fact we have a strong warm air inversion above the valley floor, fog will have a difficult time getting a foothold. The…

November 27, 2021 There are certainly signs that the valley floor has dried out. Only patchy fog prevails even though we’re under a strong warm air inversion. visibilities from Bakersfield to Madera generally range from 5 to 9 miles. There was good radiational cooling again last night under clear skies with widespread low to mid…

November 26, 2021 The drier and somewhat colder air mass has now settled on the valley floor. There is much less fog this morning, however there is an area of high clouds moving overhead. This is also helping to inhibit the formation of fog. With a drier air mass, radiational cooling has a chance to…

That weak trough of low pressure that moved through with very little fanfare about 36 hours ago did leave a somewhat colder air mass in its wake. In some cases, the first frost of the season occurred overnight with widespread low to mid 30s in the rural areas. The coldest I could find in the…
