Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
306 AM PDT Sun Apr 30 2017

.SYNOPSIS...A warming trend will be present across central
California through at least the middle of next week.

&&

.DISCUSSION...Upper level high pressure will remain the dominant
feature over the eastern Pacific through at least the middle of
next week. This will result in a warming trend across central
California. Temperatures this afternoon will be between 3 and 5
degrees warmer compared to yesterday afternoon and between 6 and 8
degrees warmer than normal.

The upper level ridge axis shifts over central California on
Wednesday...resulting in the warmest day of the week. Expect San
Joaquin Valley temperatures to warm into the upper 80s to mid
90s...around 10 degrees above normal. Temperatures expected to
cool a degree or two on Thursday...but hardly noticable...as the
upper ridge shifts east over southern California and Nevada.

An upper low is forecast to shift east toward the Pacific
Northwest coastline Friday morning with an associated digging
upper trough extending into southern California. The upper low is
then forecast to move nearly due south along the California
coastline...or depending on which model solution...directly south
through California. Either way...there does look to be a shift in
the weather pattern from hot and dry to much cooler and possibly
wet Friday into the weekend. It is still early...but as of
now...the forecast calls for a 20 degree drop in daytime high
temperatures from Thursday to Sunday.

Please continue to monitor the forecast for the latest
information.
