.DISCUSSION...

...Today...
Near normal temperatures continue today, with mid to upper 80s
expected in the Valley, Delta, and lower foothills. Daytime
humidities remain low, generally between 10 and 25% (lowest in the
northern Sacramento Valley). This, in combination with lingering gusty
winds means elevated fire weather conditions remain in the
northern Sacramento Valley through the afternoon and early evening.

...Monday and Tuesday...
Precipitation chances for Monday and Tuesday have virtually
disappeared with the most recent forecast update. Temperatures
will remain near normal through Tuesday (low to mid 80s for the
Valley), with a slight increase to daytime relative humidities.
The Delta and adjacent portions of the Valley will see breezy to
gusty winds on Monday afternoon/evening (65 to 90% chance of 30
mph or higher gusts in the Delta, 30 to 50% in the nearby
Valley), though minimal impacts are expected currently.

...Wednesday through Saturday...
Northerly winds increase as the early-week trough shifts into the
Great Basin. Gusty winds and low humidity will bring increased
fire weather concerns across the Valley, Delta, and lower
foothills, especially Wednesday and Thursday. To this point, we
have issued a Fire Weather Watch from 11am Wednesday to 5pm
Thursday. Temperatures trend higher starting mid-week as well,
with widespread Moderate HeatRisk, areas of Major HeatRisk, and
potential for triple digit high temperatures in the Valley, Delta,
and lower foothills through the weekend.
