Area forecast discussion
National Weather Service San Joaquin Valley - Hanford California
210 PM PDT sun Apr 30 2017

Synopsis...a strong ridge of high pressure will remain over
region for the next several days with warming and dry weather.

&&

Discussion...sunny skies again this afternoon with high pressure
in control. Water vapor imagery shows the ridge axis centered out
near 130w with quite extensive coverage of the east Pacific. Not
too much change in the forecast thinking this afternoon as
forecast models continue to agree in slowly moving the ridge axis
towards the coast this week. Models bring the highest heights
across the forecast area on Thursday and this should be the
warmest day with highs in the lower elevations reaching into the
lower 90s. With the full sun and warming temperatures, the may
snowmelt season will get into full swing.

By late in the week models continue to bring a big change to the
pattern as a trough of low pressure and an eventual closed low are
projected by GFS and European model (ecmwf) in the Friday to Sunday time frame.
Today's GFS is trending farther east and now brings the low over
land instead of down the coast. The European model (ecmwf) continues to project the
low will take a coastal track and close off west of Point
Conception by Monday. Lots of time to figure out this pattern
change so will just make minor changes to the weekend forecast
with slight chance of precipitation for much of the area. It will
be cooler everywhere for sure however.
