Area Forecast Discussion
National Weather Service Hanford CA
219 AM PDT Thu Jul 29 2021

.SYNOPSIS...
Slightly warmer than average high temperatures look likely into
the foreseeable future over the forecast area. Monsoonal moisture
will provide the Sierra Nevada with a chance of afternoon and
evening thunderstorms each day until Sunday.

&&

.DISCUSSION...The current pattern with warm weather and
afternoon/evening mountain thunderstorms will continue until at
least Sunday, though with some increase in coverage of showers
and thunderstorms on Friday and Saturday. Areas impacted will
include the Sierra Nevada foothills, the Kern County
mountains/desert, and the east side of the San Joaquin Valley.
Although, the east side of the Central Valley may not pick up much
more than a sprinkle or a light shower in terms of rainfall.
However, isolated thunderstorms could move into this area,
especially if development occurs over the foothills due to the
southeasterly flow aloft. The primary threats of thunderstorms
will include brief heavy rainfall, dangerous lightning, and gusty,
erratic winds.

The potential for flash flooding producing storms will become
more favorable by Friday, with the greatest likelihood over the
Sierra Nevada, as precipitable water (PWAT) will noticeably
increase, per ensemble guidance in the short-term. It does not
appear as favorable for today, as PWAT values are not expected to
remain quite as high. However, expect another round of isolated
thunderstorms over at least the higher elevations of the Sierra.

We are not expecting much change in temperatures over the next
several days, and many locations will remain in the triple digits
in terms of daily maxima for much of the period. However, the
forecast for Saturday is a bit tricky, depending on cloud cover
and storm development from the previous afternoon and evening.
Overall, highs could reach the upper 90's in the Central Valley
and the Kern County desert areas, though the warmest locations may
still report readings around the century mark on Saturday.
Probabilities of highs remaining in the triple digits are still
around 45 to 50 percent for this weekend, per blended guidance.

As for next week, a drying trend is expected as the flow aloft
turns to the southwest. However, the upper-level ridge will remain
over much of the southern half of California and the Desert
Southwest, so daily high temperatures will likely remain around
100 degrees in the warmest valley locations and 100 to 105 degrees
in the Kern County desert. Overall, the first week of August will
be seasonably warm, as this period, as well as much of the latter
half of July, is the warmest time of the year in terms of
climate.

&&

.AVIATION...
Showers and isolated thunderstorms likely through 03Z Thur in the
Sierra, primarily north of Sequoia National Park. Otherwise, VFR
conditions will prevail through the next 24 hours.

&&

.AIR QUALITY ISSUES...
On Thursday July 29 2021... Unhealthy for sensitive groups in
Fresno... Kern... Madera... Merced and Tulare Counties and Sequoia
National Park and Forest.
