...New SYNOPSIS, SHORT TERM, LONG TERM...

.SYNOPSIS...
Issued at 109 PM PDT Sat Apr 12 2025

Cooler temperatures continue tonight, but warmer and drier
conditions begin on Sunday and continue into early next week.
Close to normal temperatures return midweek.

&&

.SHORT TERM...
(This evening through Sunday)
Issued at 109 PM PDT Sat Apr 12 2025

Mostly clear skies leading into the night with pretty light to
moderate winds, as the trough begins to depart to the east making
room for a weak ridge to build. There is a chance for some patchy
low clouds or fog development overnight near Monterey Bay and North
Bay (especially near Napa), but after the early morning hours, clear
skies will return. With the ridging pattern, there will be moments
of offshore winds, which will help facilitate some warmer
temperatures and drier conditions on Sunday. Minimum temperatures
overnight will gradually increase but will remain mostly in the
40s but the noticeable temperature increase will be Sunday. Max
temperatures will rise about 5-15 degrees above normal for the
next couple of days, with inland areas seeing values in the mid
70s to low 80s and coastal areas will see mostly 60s to low 70s on
Sunday. With the uptick in temperatures for Sunday and Monday,
most of inland region is highlighted for minor HeatRisk, for those
who are extremely sensitive to heat.

.LONG TERM...
(Sunday night through next Friday)
Issued at 109 PM PDT Sat Apr 12 2025

Dry and warm conditions continue into Monday with a slight uptick in
max temperatures compared to Sunday. Clusters continue to show
agreement of the upper level low forming off the coast of southern
CA on Tuesday allowing for temperatures to gradually decrease to
values that reflect normal seasonal temperatures, especially inland.
With the low pressure forming, there is a chance for increase cloud
cover which will also help temperatures to moderate. Although the
NBM shows less than 10% chance for precipitation over our area on
Wednesday, expect dry conditions to continue through the week as
of now. Models also show another pattern change Friday where
another ridging pattern can possibly bring another weekend of
warmer temperatures. Stay tuned!
