.DISCUSSION...
High pressure is building over our area with an upper-level
shortwave off the Central CA coast based on latest satellite
images. Expect warmer temperatures today and a gradual warming
this weekend into early next week. High temperatures in the
warmest locations will reach the mid to upper-90s today, and a
few locations, such as in the Indian Wells Valley in
northeastern Kern County, reach into the triple digits by
Saturday. Thunderstorms in the Sierra Nevada have a low to
moderate (15-30%) chance of development this afternoon and will
likely dissipate by the early evening. Slight (10-20%) chances
for afternoon thunderstorms continue over the weekend.
Otherwise, dry conditions prevail throughout our portion of
Central CA.

High temperatures will continue to warm Sunday into early next
week. More locations can expect to reach triple digits. Chances
for triple digit heat from Saturday into the middle of next week
range from 25-50 percent in the SJ Valley to around 30-60
percent for the Kern County desert, with the best chances
towards Ridgecrest/Inyokern. Afternoon humidity will also remain
quite low in these hot spots and could lower a bit by the
middle of the week. A low to moderate risk for grass or brush
fires exists. Practice cold water safety if venturing into the
lakes and waterways, as water continues to flow cold and fast!
