December 17, 2018 Summary: Skies have cleared over sections of the west side of the valley north of Kern County.  However, plenty of upslope clouds continued to be banked up against the valley facing slopes of the surrounding mountains.  These clouds will more than likely remain through the night and into Tuesday morning.  Where it…

December 17, 2018 Summary: This storm has turned out to be a generous precipitation maker over northern California.  The Mt. Shasta/Siskiyou region has received 1-3 inches with 2-3 inches over the northern half of the Sierra Nevada.  Radar indicates the back side of the cold front will clear the valley later this morning.  By this…

December 16, 2018 Summary: Clouds are increasing over the  northern half of the valley at this hour.  Generally light precipitation is occurring from roughly a Bay Area/Sacramento line north.  The main frontal system is still just off the northern California coast.  It will spread significant amounts over the northern third of the state with possibly…

December 15, 2018 Summary: Generally clear skies prevail across the valley this afternoon with the exception of some high clouds which have spread as far southeast as Fresno County.  Those high clouds are well in advance of a massive low which is centered west of British Columbia with its associated cold front  moving into western…

December 15, 2018 Summary: Skies cleared overnight, allowing radiational cooling to lower temperatures at frost stations into the low to mid 30s.  The back side of the trough of low pressure is now into the interior west, allowing a very temporary ridge of high pressure to move overhead today and tonight.  The high, however, will…

December 14, 2018 Summary: Extensive cloud cover continues to move over central California ahead of an approaching and weakening trough of low pressure which will spread precipitation over parts of northern California tonight.  However, the frontal system will wash out before it reaches central California.  A weak ridge will very temporarily move in from the…

December 14, 2018 Summary: A blanket of high clouds based at between 2,000 and 2,500 feet moved in from the southwest overnight, resulting in fairly mild temperatures.  Most frost stations were in the mid to upper 30s.  One of those quirks of nature occurred overnight.  We have a surface high centered over the Great Basin…

December 13, 2018 Summary: It has been quite some time since we’ve seen wall to wall sunshine throughout the valley, but satellite imagery indicates there’s not a cloud to be found.  Visibilities are pretty good by December standards, running about 8 miles.  Temperatures and dew points are averaging about a degree higher than 24 hours…

December 13, 2018 Summary: A ribbon of fog has developed mainly along the west side of the valley this morning from northwest Kern County up through eastern Merced County.  Currently, there are two high pressure systems.  One is roughly right above us.  It has driven the freezing level back up to 12,400 feet.  The second…

December 11, 2018 Summary: Satellite imagery is depicting low clouds based at 3,200 feet over Porterville, Hanford, and Fresno.  Most of Kern County is relatively clear as is Madera County and points northward.  The low clouds along the eastern sector of the valley seem to be expanding towards the southwest.  There’s only a minimal amount…
