Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
110 PM PDT Sat Jul 21 2018

.SYNOPSIS...
Weak high pressure will keep in the warmth but also the humidity
for the rest of this weekend across central California. There
remains the slight chance for afternoon and evening thunderstorms
over the high Sierra Nevada Mountains. Otherwise, it will remain
dry with slightly above normal temperatures into Monday. Even a
bigger heat wave is in store by the middle of next week.

&&

.DISCUSSION...
Moonsoon moisture will be first to mention in the short term
forecast. It will be of the mid and upper level variety this
evening and overnight. Thinking is there will enough for a partly
to mostly cloudy sky over central CA. This will spread northwest
from a thunderstorm complex currently over Las Vegas area. This
cloud cover will also keep the hot temperatures from falling much
this eve. In fact, parts of the San Joaquin Valley are likely to
hold in the 80s most of the night.

Current thinking is some clearing over the forecast area Sunday
morning. Actually, Sunday looks to be the least hot day of the
week with highs in the upper 90s to lower 100s across the valley
and adjacent lower foothills. Surface wind should remain light.

Current mesoscale models showing widely scattered thunderstorms
continuing over the Sierra Nevada crest each afternoon and
evening. It's hard to pinpoint where convection will be the
strongest over the mountains, but the instability will certainly
be in place from near Yosemite National Park to parts of the Kern
County Mountains.

Mid/upper level heights continue to build early next week, which
means even hotter conditions for the entire region. Excessive Heat
Watch will remain in place for the lower elevations beginning
Tuesday afternoon. Temperatures across the Kern County Desert and
San Joaquin Valley will easily exceed 100F almost all of next
week. It will also remain dry with lower humidities, which will
challenge ongoing wildfires in the Sierra. Will monitor both the
strong heat and wildfires as we move into the last full week of
July.

&&

.AVIATION...
Areas of MVFR visibility in smoke will continue in the vicinity of
the Ferguson Fire in Mariposa County for at least the next 24 hours.
A slight chance of thunderstorms will be possible near the Sierra
crest until about 04z today and Sunday. Gusty outflow wind can be
expected near any storms. Otherwise, VFR conditions will prevail
over the central California interior during the next 24 hours.
