Area Forecast Discussion
National Weather Service Hanford CA
1223 PM PDT Sun Apr 18 2021


.SYNOPSIS...The upward trend in temperatures will continue through
Monday, with afternoon highs ending up 10 to 15 degrees above
normal levels. A weak disturbance late Tuesday into Wednesday
will bring cooler temperatures and breezy to locally gusty
conditions especially for the Kern County mountains and desert
areas, and increase chances of light precipitation to the higher
elevations of the Sierra on Wednesday and Thursday. Dry conditions
with increasing temperatures will return by the end of next week.

.DISCUSSION...Blocky pattern continues with an omega block pattern
in place over the eastern Pacific and west coast. The ridging
associated with this setup will continue to transition slowly
eastward and has brought warming temperatures. Monday high
temperatures will be running about 10 to 15 degrees above normal
levels which for both Fresno and Bakersfield currently sits at 75
degrees. There is a 98 percent chance on Monday that Fresno will
have a high temperature greater than 85 degrees, that percentage
drops a bit for Bakersfield to 84 percent. A few locations hitting
the 90 degree level is not out of the question and for Fresno
there is a 27 percent chance of that occurring but only a 12
percent chance for Bako.

Monday looks to be the warmest day of the workweek as slight
cooling takes place on Tuesday when a weak disturbance rides into
the region after it moves through the Pacific Northwest through a
saddle in the omega feature and transitions southeastward over the
west coast into our neck of the woods. This weak system will bring
some synoptic cooling, breezy to locally gusty conditions, and
slight chances of light precipitation for the higher elevations of
the Sierra. Expected precipitation amounts will be about two
hundredths of an inch or less where it does occur. The stronger
winds will be in the wind favored locations of the coastal hills
and the Kern County mountain passes and desert areas. At this time
the gusts in the Kern Mountains could approach 40 mph on Monday
night into Tuesday as the system approaches and again on Tuesday
night into Wednesday with the disturbance over the region.

Ridging then once again rebuilds into the region by late Thursday
and will bring a return to warmer temperatures. High temperatures
across the San Joaquin Valley on Friday and into the weekend will
be in the mid to upper 80s once again. But hey, we should
continue to enjoy this, because triple digits will be here before
we know it.
