Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
238 AM PDT Mon Oct 23 2017

.SYNOPSIS...Dry weather and above normal temperatures will prevail
through the forecast.

&&

.DISCUSSION...An upper level ridge of high pressure will continue
to build north into the Pacific northwest today...resulting in a
warming trend across the area. Temperatures this afternoon will be
anywhere from 7 to 10 degrees warmer compared to yesterday
afternoon and between 5 and 10 degrees above normal for this time
of year.

Surface high pressure will begin to build over the Great Basin
today into Tuesday with low pressure off the southern California
coastline. This will bring offshore winds to the area...dropping
relative humidity values...especially over the Kern County
mountains. Surface pressure gradients tighten on Tuesday morning
resulting in northeast wind gusts in excess of 45 mph over the
Kern mountains. The dry conditions in combination with strong
offshore winds will create critical fire weather conditions today
into Tuesday. Please continue to monitor the forecast for the
latest information.

Otherwise...continued warming is expected as the ridge amplifies
into the middle of the week. Wednesday looks to be the warmest day
of the week...with temperatures between 10 and 15 degrees above
normal. In fact...a few valley spots could reach the low 90s.

Although we are a full month into Fall...Summer will not let up
in central California. According to the Climate Prediction Centers
6 to 10 and 8 to 14 day outlook...there is still a good chance of
above normal temperatures into the first week of November.
