Area Forecast Discussion
National Weather Service Hanford CA
144 PM PDT Sat Jun 1 2019

.SYNOPSIS...
An area of low pressure will remain over Southern California
tonight and Sunday and influence the weather over our forecast
area. This feature will continue to bring a continued threat of
afternoon and evening thunderstorms over mainly the mountain
areas. However, isolated storms are even possible over the east
side of the San Joaquin Valley and into the Kern County desert for
the remainder of the weekend. Temperatures will remain generally
seasonal for this time of year until Monday, and then warmer than
average temperatures are expected as high pressure builds over the
area.

&&

.DISCUSSION...Showers and isolated thunderstorms have developed
over the Sierra Nevada and Kern County mountains. Scattered
showers and thunderstorms are also possible once again over the
higher terrain to the west of I-5 in Fresno County. Storm motion
is generally from the east at this time but remains very slow, so
heavy rain is once again a possibility with the strongest storms.
Drifting of debris clouds and even isolated thunderstorms is a
possibility on the east side of the San Joaquin Valley later this
afternoon into this evening, as the upper-level low remains
centered off the coast of Santa Barbara, or south of the Channel
Islands. Temperatures are a bit warmer this afternoon compared to
this time yesterday but are expected to remain around or slightly
above seasonal averages for the remainder of this weekend.

This upper-level low will make little eastward progression through
Sunday. Thus, the threat for more afternoon and evening showers
and thunderstorms continues over the mountain areas, though is
expected to begin to decrease by early in the week. The upper-
level low will slowly move to the east on Monday and over the
Colorado River Valley by the afternoon and into the evening.
However, residual moisture will likely trigger additional
thunderstorms over the Sierra Nevada as late as Tuesday.
Otherwise, expect significantly warmer temperatures, or around 5
to 10 degrees above average during the middle part of the week.
It appears this warmth will be short-lived, and a return to
lower temperatures, or several degrees below average, remains a
possibility by Friday and next weekend as a trough of low
pressure moves over the Pacific Northwest and Northern California.
Precipitation associated with this system remains well north of
our forecast area, per latest model runs.

In addition to the current weather concerns, melting snowpack will
continue over the higher elevations of the Sierra Nevada. Rivers
and creeks will continue to rise over the next several days as
more snow melts, and temperatures warm.

&&

.AVIATION...
Scattered thunderstorms will impact the mountains until about 03z
Sunday. Regardless, VFR conditions will prevail at MCE, MER, FAT,
VIS, and BFL through at least the next 24 hours.

&&

.AIR QUALITY ISSUES...
None.

&&

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

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