.DISCUSSION...
Seasonal conditions are currently resent for central California
as zonal flow is gradually setting up over the region. This
pattern is resulting from a trough located over the northeast
Pacific and an area of high pressure building over the Desert
Southwest. Temperatures through the weekend are expected to be
near average for this time of year, with widespread highs in the
San Joaquin Valley in the upper 90s; there is also a 20 to 50
percent chance for triple-digit temperatures Friday and
Saturday. The warming temperatures will result in a decrease in
relative humidity over the area. Weekend minimum values of 20 to
25 percent are expected for the San Joaquin Valley, and Sierra
foothill and mountain areas along with values less than 10
percent in the Kern Desert. There is also potential for gusty
winds in the typical wind-prone locations, including Pacheco
Pass, Lake Isabella, and the Mojave Slopes with the upcoming
pattern. This may further enhance fire risk when combined with
the lowered RH values.

A brief cooldown is anticipated early next week as a shortwave
low pressure trough passes through northern California and the
Pacific Northwest. For Monday, there is less than a 40 to 50
percent chance to exceed 95 degrees in the San Joaquin Valley.
This cooldown will quickly be replaced with a warming trend for
the remainder of the week as high pressure builds in. There is a
35 to 85 percent chance for afternoon highs to exceed 100
degrees Wednesday through the weekend, and a low chance (15 to
25 percent) to exceed 105 degrees.
