National Weather Service San Joaquin Valley - Hanford California
302 am PST Mon Nov 20 2017
a weak disturbance will mainly bring high clouds to central
California with a slight chance of showers near Yosemite today.
Otherwise, a ridge of high pressure builds over the region through
the week. This will result in dry conditions and warming
temperatures. Temperatures will be well above normal most of the
large area of high pressure over the region will hold in through
the week. A cold front moving into the pacnw is bringing clouds
and precip into nrnca. We have kept in a slight chance of showers
across Yosemite, but otherwise it will be dry. Some valley fog has
developed...but nothing dense yet. Plenty of high and mid level
moisture moving across the region.
Temperatures have gradually been warming up and will continue to
near record levels by Wednesday and even possibly on Thanksgiving
day. Unseasonably warm conditions through the week. Dry with only
some patchy ground fog possible in parts of the sjv.
Models are advertising a cold front to approach the region from
the northwest by Sunday and a possible chance of showers mainly across
the Sierra on Monday. It is still a ways out and confidence is low
for that potential system.
areas of MVFR with local IFR conditions in fog across the San
Joaquin Valley until 18z Monday. Otherwise, VFR conditions will
prevail across the central California interior during the next 24 hours.
