November 19, 2020 – A few lingering showers this morning across far northern California, otherwise dry weather thru the weekend. Mild days and cool nights expected with areas of morning frost across the Central Valley.
Discussion
Radar indicates some light showers continuing early this morning across Shasta County while the remainder of the forecast area has returned to dry weather after another day of active weather on Wednesday. Surface observations across the Central Valley are reaching saturation with generally light winds, and some patches of fog have begun to develop despite the area of high clouds moving overhead.
Upper trough continues to weaken over NorCal today as the stronger short-wave brushing across far northern California lifts out into the northern Rockies. The remaining showers over the far northern portion of the state are expected to taper off this morning. Some patches of thicker fog will be possible in the Sacramento and Stockton areas during the morning commute.
Otherwise, dry weather with relatively mild days and cool nights is expected through the weekend. Light to moderate northerly flow will develop through the Central Valley today ushering in drier air, so less late-night and morning fog is expected by Friday, but areas of early morning frost will become likely for wind- sheltered areas along the eastern half of the valley.
Extended discussion (Monday through Thursday)
Generally tranquil weather is expected to continue into early next week. 00Z GFS and ECMWF maintain dry conditions for much of the area with precipitation chances remaining to the north and west. National Blend of Models trickles some precipitation chances inland to the northern Sacramento Valley and northern Sierra for late Sunday/Monday with minimal QPF.
