.DISCUSSION...

...Next 7 days...

The strong upper level high pressure will move
off to the east a bit this weekend as some energy pushes into the
Pacific Northwest. This will bring slightly cooler temperatures
this weekend but still very much above normal with normals from 65
to 70 and highs still from the mid to upper 80s. The energy
moving across PacNW will bring a breezy period to the west
Sacramento Valley Sunday but will be well below advisory criteria
but will continue to dry out fuels. Fire weather concerns are
minimal with this, for now. The upper ridge does build back to the
west once again early in the week, and even being on the western
side of it, it still will bring unseasonable temperatures. Hottest
conditions will continue to be from Sacramento southward closer
to the base of the ridge. Daily record highs will once again be
possible to likely in Sacramento, Modesto and Stockton through mid
week.

If you are outside or planning outdoor activities this weekend
into next week, please remember to drink plenty of water and wear
sunscreen. As this is an anomalous heat event, individuals may
not be fully acclimated to the emerging heat. Local waterways are
also running very cold due to snowmelt.
