.DISCUSSION...
Deep trough digging over Central California is providing the
area with a significant cool-down. Yet, along with a drop in
temperatures, winds have seen a significant increase as strong
winds blanket Central California. The lack of moisture across
the region has also elevated the concerns of fire starts as
windy and dry conditions exist this Saturday. Both wind fire
weather products are in effect during trough passage with
conditions settling down on Sunday.

After having temperatures reach the century mark late in the
week, Probability of Exceedance (PoE) of reaching 90 degree will
remain at low percentages over the weekend as Valley
temperatures struggle to reach 90 degrees. PoE of 90 degrees
reaches the 50% mark by Monday and shows a steady claim during
the week. PoE of 100 degree hits the 50% mark on Thursday with
PoE of reaching 95 degrees at 80%-95%. Therefore, will expect
max temperatures to hover near 100 degrees later in the week and
into the weekend. While some uncertainty exist in the later
periods, will expect max temperatures to hit 100 degrees at the
more favored locations around the Friday and next Saturday time
frame.

Wind will remain an issue as the next disturbance is ready to
cross the district later today. Ensembles surface pressure
analysis is indicating the gradient from KSFO to KLAS reaching a
range of 16mb-19mb this afternoon. At these levels, wind
gusting to 50-60 mph have high confidence of occurring as PoE
values sit at around 70%-90% range. Therefore, will maintain the
High Wind products in place and extend the Red Flag Warning
through Sunday as humidity will be slow to rise during the
weekend. By Sunday afternoon, ensembles cut the gradient in half
as winds are expected to diminish. Afterward, the slow building
of the ridge pattern will keep winds down as temperatures take
center stage for the next warm-up later in the week.
