Every reporting weather station between Bakersfield to just south of Redding is reporting visibilities anywhere from 0 to ¼ of a mile.  The weak trough of low pressure that moved through to our north yesterday evening has also lifted the fog deck higher into the atmosphere.  T he fog now covers the lower foothills on…

December 21, 2020 Summary: Upper level high pressure is weakening ahead of a fast moving trough of low pressure moving into the Pacific Northwest.  Hazy sunshine is dominant from roughly  Visalia southward in the south valley.  Porterville has warmed up to 58 degrees as has Bakersfield.  It is downright cold from central Tulare County northward…

Dense fog ranging from 0 visibility to ¼ mile extends from just west of Bakersfield northward into the lower Sacramento Valley.  Right along the edge of the fog bank in the citrus belt near the Sierra Nevada foothills, temperatures rocketed down into the mid to upper 20s with mid 30s towards the center of the…

Summary: We are very close to a full fledged fog regime.  Kern County and areas along the foothills on both sides of the valley have generally clear skies with readings in the low to mid 50s.  However, from roughly just north of Delano northward through Merced County, visibilities in many locations were still down to…

Dense fog is more widespread this morning than any morning so far this winter.  The fog extends from southwest of Bakersfield clear into the lower Sacramento Valley.  Some of the foothill communities are still in the clear, but it is approaching Lindsay and Porterville.  This is one of those classic winter mornings where a race…

December 19, 2020 Summary: Upper level high pressure continues to shift eastward over California as a warm air inversion tightens up over the valley floor.  As of 1:30, the sun was shining in most areas of the valley with temperatures approaching the 60 degree mark.  Both Madera and Merced were still under a low overcast…

California is now on the eastern flank of upper level high pressure over the eastern Pacific.  This high will slowly shift eastward, blanketing California and into the interior west.  This is tightening the warm air inversion above the valley floor.  The balloon sounding above Oakland a few hours ago indicated the freezing level has risen…

December 18, 2020 Summary: We are now under the eastern rim of upper level high pressure over the eastern Pacific which is creating a north/northwest flow aloft.  As of 1:00pm, the fog and low clouds had not burned off in some areas of the valley.  For example, Visalia was reporting a low cloud deck at…

Infrared satellite imagery which depicts fog and low clouds indicates plenty of both blanketing Tulare and Kern Counties with even a ribbon of low clouds as far north as eastern Fresno County.  In the wake of yesterday’s uneventful storm, we are now under a north/northwest flow aloft which is sandwiched between building high pressure off…

December 17, 2020 Summary: The shower activity has ended over the valley floor with only dismal amounts of rain.  Most locations reported just trace amounts to a few hundredths.  The trough of low pressure is now moving into Nevada and southern California.  There is currently a  brisk northwest flow wrapping around the backside of the…
