Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
1257 PM PDT Tue Oct 23 2018

Clear, chilly nights and mostly sunny, warm days can be
expected over the central California interior through the
weekend. High temperatures will cool to near normal by early
next week with a continuation of dry weather.


The beautiful fall weather looks to continue into next week as
central California will be the beneficiary of moderate to strong
ridging while a fairly active northern stream continues across
the CONUS. High temperatures will remain near to slightly above
later this week while overnight temperatures remain cool under
clear skies will allow for good radiational cooling. Patchy haze
will be possible each night for areas in the central San Joaquin
Valley due to these nighttime cooling temperatures and weak winds.

Smoke will still be an issue for parts of the central eastern
Tulare County over the next several days as the Alder Fire burns.
Weak winds will allow the diurnal wind regime to direct the smoke
downhill overnight and mostly upslope during the days. The smoke
therefore looks to remain a very localized issue.

Save a few weak cool frontal passages with minimal impacts
through the weekend, the only other feature that looks interesting
at this time is a trough that drops southward late Sunday night
into Monday morning. However, it looks to stay just a bit too far
north which should minimize impacts, some gusty onshore winds and
even a marine intrusion may be the only impact. But, if the models
trend further south with this system that could create
precipitation chances especially for the higher elevations and
then followed by a northerly and cooler flow to the region. We
will continue monitoring that as we move through the coming days.


VFR conditions will prevail at MCE, MER, FAT, VIS, and BFL through
at least the next 24 hours. A dissipating cold front will approach
the San Joaquin Valley tonight, resulting in no more than few to
scattered clouds at or above 10,000 feet.





The level of certainty for days 1 and 2 is high.
The level of certainty for days 3 through 7 is medium.

Certainty levels include low...medium...and high. Please visit
