.DISCUSSION...
An area of high pressure is building over southern California
today, starting a warming trend which will drive temperatures
above season averages. There is a 20 to 60 percent chance for
afternoon highs to exceed 105 degrees in the San Joaquin Valley
on Friday and Saturday, with localized areas up to 70 percent.
In addition, there is a 30 to 70 percent chance for highs to
exceed 100 degrees in the Sierra Foothills, including Lake
Isabella and Yosemite Valley. Minimum temperatures in the upper
60s for the valley areas, and the low to mid 70s in the foothill
areas, will pair with the triple digit heat to cause widespread
moderate heat risk for central California through the early part
of next week. As such, a Heat Advisory has been issued for a
large portion of the region, running from Friday morning through
late Tuesday evening.

The warming temperatures bring lowered relative humidity, with
widespread values 15 to 20 percent expected into the weekend;
desert values will continue to be in the single digits. This
will prolong dry conditions favorable for fire development,
however with subsiding air aloft associated with the area of
high pressure, winds will generally be light. The strongest
winds will be in typical wind-prone areas such as the Mojave
Desert Slopes, Lake Isabella, and Pacheco Pass, with the diurnal
cycle being the main driver.
