Area Forecast Discussion
National Weather Service Sacramento CA
1005 PM PDT FRI SEP 23 2016

.SYNOPSIS...
Very warm and dry through early next week with breezy north winds at
times through the weekend.

&&
.DISCUSSION...
Although max temps were a few degrees below normal on Fri...they
were some 5 to 10 degrees warmer than Thu. This (Fri) will be the
last day of below normal max temps for awhile...most likely until
next Thu...so prepare for summer-like temps during the first week of
autumn. 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...but it will continue
to very warm through the middle of next week.

A mid cloud deck is spilling over the building ridge and into Norcal.
The clouds have been persistent over the Nrn portion of the CWA...
with a few sprinkles reported midday in the RDD area...but have been
eroding as they make their way Swd towards the I-80 corridor. This
looks like the trend through about 12z Sat when finally the clouds
will erode/dissipate according to the RH profiles. This will pave
the way for sunnier skies for the weekend. JHM

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
