December 27, 2017 Summary: Visibilities this afternoon are about 3 to 4 miles from Madera southward to Bakersfield.  Air temperatures are actually a bit cooler than 24 hours ago with readings generally in the upper 50s to the lower 60s.  Upper level high pressure continues to be anchored off the California coast with the storm…

December 27, 2017 Summary: The weather pattern for the remainder of the week will be stagnant as strong upper level high pressure continues to create a warm inversion above the valley floor.  Temperatures at about 4,000 feet are actually in the low 50s.  the freezing level is at 12,100 feet.  In the meantime, on the…

December 26, 2017 Summary: Temperatures have warmed into the low to mid 60s this afternoon which is anywhere from 4 to 7 degrees warmer than yesterday.  Abundant sunshine and building upper level high pressure are moving daytime temperatures upward.  Dew points are running in the mid to upper 30s this afternoon, pretty much a ditto…

December 26, 2017 Summary: There were two layers of cloud cover streaming overhead during the night.  one was based at 15,000 feet and the second was at 18,000 feet.  These clouds did an excellent job of keeping temperatures in the 30s overnight.  The coldest location I could find was 30 at McFarland.  That will not…

  Christmas Day, 2017 Summary: The main emphasis of this report will  be on overnight low temperatures.  Once again,  cloud cover will play a central role, especially during the early morning hours. Satellite imagery shows is a batch of high clouds just off the central coast which will move on shore later this evening.  However,…

Summary: A veil of high clouds based above 20,000 feet continues to stream over northern and central California.  From the Tehachapi Mountains southward, skies are largely clear.  These high clouds continue to overrun a ridge of upper level  high pressure located just off shore and are projected by models to continue to do so through …

Summary: A veil of high clouds based above 20,000 feet continues to stream over northern and central California.  It certainly helped last night as just about all frost stations were in the mid 30s as of 6:00am.  Model information this Christmas Eve shows the high will remain anchored off shore with a westerly flow riding…

Summary: Skies are mostly clear over the southern 2/3 of the valley this afternoon with mid and high-level clouds from Fresno County northward.  These clouds continue to move over the top of strong high pressure off shore then slide southeastward along the eastern rim of the high.  They eventually dissipate over the Desert Southwest.  This…

Summary: Considerable amounts of high, mainly thin, clouds are streaming in, overrunning a strong ridge of upper level high pressure located off shore.  Even with the high clouds, temperatures in the coldest locations dipped into the upper 20s last night with widespread lower 30s.   The off shore ridge will remain along the west coast…
