   into Monday.

.DISCUSSION...

Warm and dry conditions expected today as ridging remains in
control of the large scale pattern over the area. Above normal
temperatures will rule with 90s across the Valley. This will bring
minor to moderate HeatRisk but no concerns for heat headlines.
Delta Breeze will continue to bring evening relief through the
Delta into the Sacramento area.

Thursday is a transition day as a cooling trend begins and
continues into the weekend. A deep trough from the Gulf of Alaska
will slowly dig into the Pacific Northwest Friday into the weekend
and gradually move east into the Great Basin. This will increase
onshore flow for our area on Friday and into Saturday, with
breezy southerly winds across the area and slightly increased
moisture profiles. There is a slight chance (10-20%) for light
showers and isolated mountain thunderstorms on Saturday,
primarily in the Burney Basin, southern Cascades, and far northern
Sierra.

As trough departs, potential for a north wind event increases for
Sunday into Monday. There is still some uncertainty in ensemble
solutions with timing, strength, and exact path of the trough,
but there is some potential for elevated fire weather conditions
on Sunday and into Monday. Check back in for updates to the
forecast as the weekend gets closer!

.AVIATION...
