.DISCUSSION...

...Sunday through Monday... A weak trough will disrupt ridging
aloft this afternoon and evening. While there is still a non-zero
chance for precipitation in Shasta County this evening, most
likely high-res solutions show little to no rain reaching the
ground. Ridging builds back in on Monday, starting a gradual
warming trend across interior NorCal. North to east winds will be
breezy through the northern and central Sacramento Valley and the
Sierra mountains/foothills on Monday with gusts 15-25 mph at
times. These winds will work against widespread dense fog
development in the central Sacramento Valley, but isolated
coverage is still possible in the southern Sacramento Valley, with
more widespread dense fog likely in the northern San Joaquin
Valley tonight and Monday night.


...Tuesday through Saturday... Ridging continues to build across
the area through much of next week, bringing gradually warming
temperatures, along with continued chances for morning fog. Temperatures
will climb to above normal by mid-week, and strong inversions
will keep conditions warm and dry in the foothills through
midweek. Otherwise, breezy offshore flow is expected at times.

Ensemble guidance highlights another shortwave trough approaching
the region towards next weekend which is expected to bring cooler
temperatures and potential for unsettled weather. There is still a
high degree of uncertainty in the timing and amounts of any
precipitation however, so check back in as we get closer for
forecast updates.
