Flooding concerns continue as runoff from the recent rain
continues to work its way downstream adding stress to waterways. A
couple of weak but cold storms move through today and Sunday/Monday.
Extended period of dry weather starts by the middle of next week.


Low pressure system along the coast will move southward during the
day and may bring a few stray showers to the interior valley this
afternoon. The mountains will see a few more showers but any
snowfall accumulations will be light and generally less than an
inch. The system will move south of the area overnight and
precipitation chances will diminish. Skies will become clear and
another cold night is on tap. Temperatures will lower into the
low to mid 30s by Sunday morning. The coldest temperatures look to
be over the north end of the valley.

Another cold system will move into the interior Sunday afternoon
and evening and bring more low elevation snow but in light
amounts. Have moved the timing back a few hours for the Winter
Weather Advisory due to the slower pace of the storm moving over
the interior.

A trough will remain over the region on Monday and residual
showers will likely linger over the mountains but for the most
part expect dry weather. Tuesday night as any lingering showers
diminish is when the interior region will start its extended
period of dry weather.



Dry weather is expected in the extended period as upper level
ridging forms over the west coast. A Pacific storm system weakens
the ridge near the end of the week. Current models keep
precipitation north of our forecast area. Temperatures warm
throughout the week with maximum temperatures within a few degrees
of average Tuesday and Wednesday, warming to a few degrees above
normal by the end of the extended period.



Mainly VFR conditions across the region except for occasional MVFR
ceilings over mountains next 24 hours with intermittent showers.
Snow levels 3000 feet and higher. Mainly northwest to northeast
winds below 10 knots at TAF sites. JBB

Winter Weather Advisory from 1 PM to 10 PM PST Sunday for Shasta
Lake Area / Northern Shasta County-West Slope Northern Sierra
Nevada-Western Plumas County/Lassen Park.

Flash Flood Watch through late Thursday night for Carquinez
Strait and Delta.
