normal by the end of the week.

.DISCUSSION...
Upper level ridging is spreading in from the Pacific and this is
going to be the dominate weather pattern through the weekend and
into next week. After a cool start with upper 40s and lower 50s in
the Valley and 20s and 30s in the mountains, temperatures have
warmed significantly. Temperatures this afternoon have been 4 to
9 degrees higher than yesterday. The temperatures will trend
higher through the weekend, with little or no Delta breeze
expected. Low to mid 90s are expected in the Valley Saturday, mid
to upper 90s on Sunday. The northern Sacramento Valley could see
temperatures reaching the 100s Sunday afternoon. Monday may be
slightly less hot as the ridge axis shifts east of the region.

Surface high pressure building to the north will increase the
pressure gradient and surface winds this weekend. Breezy
northerly winds coupled with low humidity will bring periods with
increased fire danger late Saturday into early Monday. This bears
watching, with potential fire products if winds trend stronger. EK

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)

High pressure ridging shifts east as an upper trough moves into
the Pacific Northwest. The weather for the extended period remains
dry, with the main effects being a gradual downward temperature
trend through the week. Highs will be below normal by Thursday
and Friday. EK
