November 22, 2017 Summary:  There is a great deal of fog and low clouds from Fresno County northward, basically up the central and west side of the valley.  The fog is more patchy further south due to an off shore flow which is affecting southern California.  Dew points are slightly lower in Tulare County and…

November 21, 2017 Summary: A winter style warm air inversion is setting up over the valley floor.  The only difference is that there is not quite enough moisture available at ground level to create a full fledged fog regime.  Nevertheless, areas of fog and low clouds will again form towards the center of the valley,…

November 21, 2017 Summary:  A strong upper high center remains over the southwest of San Diego this morning.  The main storm track runs from southwest to northeast into the Pacific Northwest with clouds moving into northern California and with high clouds moving over central California, as well.  These clouds are simply overrunning the high and…

November 20, 2017 Summary: Temperatures this afternoon are running anywhere from one to six degrees warmer than 24 hours ago.  The freezing level is up at 12,800 feet, meaning the air aloft is also quite warm.  California is essentially cut in half with heavy cloud cover from Fresno north and generally clear skies to the…

November 20, 2017 Summary:  there is considerably less fog this morning due to a stream of mid and high level clouds which are caught up in a west/southwesterly flow aloft ahead of a weakening cold front which is now moving into northern California.  Doppler radar indicates there is quite a bit of shower activity over…

November 19, 2017 Summary:   Skies generally cleared overnight, allowing strong radiational cooling to occur.  Most frost stations were in the mid 30s to the lower 40s this morning and the usual fog prone locations lived up to their reputation as places like Lemoore, Hanford, Tulare, and Merced were each reporting a quarter mile visibility or…

November 18, 2017 Summary:   Skies have cleared over central California.  The lone exception is portions of Kern County where low clouds are still banking up against the north facing slopes of the Tehachapi Mountains.  These clouds will slowly dissipate as the surface flow briefly becomes off shore.  Temperatures this morning are generally in the upper…

November 17, 2017 Summary: Temperatures are close to 20 degrees cooler in Kern County than they were 24 hours ago.  Even further north, readings are a good 7 to 10 degrees off of yesterday’s readings.  A cooler air mass has now taken over behind a cold front which moved through during the predawn hours.  Temperatures…

November 17, 2017 Summary:   The atmospheric river of air finally moved southward overnight and is currently draped over the Kern County mountains and is moving into southern California.  Doppler radar is still showing pockets of showers, mainly on the east side of the valley from Fresno County southward, but as the main energy feed continues…

November 16, 2017 Summary: Down sloping off the Kern County mountains with a southeast flow up the valley has warmed temperatures well into the 70s this afternoon with some locations in Kern County pushing 80.  The air mass ahead of a frontal system and a very moist flow across north/central California this afternoon remains in…
