A High Wind Warning is in effect for the Mojave Desert Slopes until 2 AM PDT Wednesday morning. Blowing dust will reduce visibilities at times.

High temperatures throughout Central California Thursday afternoon will be six to eight degrees warmer than Wednesday afternoon. Maximum temperatures across Central California Friday afternoon will be 3 to six degrees warmer than Thursday afternoon.

A warming trend is expected through this weekend. By Sunday afternoon, high temperatures across Central California will be around ten degrees above normal for this time of year. Here are probabilities of maximum temperatures of 90 degrees or higher for select locations in the San Joaquin Valley from Thursday, May 9th, 2024 through Monday, May 13th, 2024.

A few strong thunderstorms are possible in the Sierra Nevada each afternoon Friday through Sunday. The primary thunderstorm hazards will be dangerous cloud to ground lightning strikes, small hail, and wind gusts near 45 mph.

As temperatures trend upward through the week, by this weekend we will experience some of the warmest conditions so far this year. High temperatures on Saturday will be around 10 degrees above normal. These temperatures will lead to a few areas in the San Joaquin Valley with a moderate risk for heat related illness, Although much of the population will experience minor impacts, this level of heat can affect individuals who are sensitive to heat, such as older people and those with underlying medical conditions, especially those without effective cooling and/or adequate hydration. Conditions will be similar again on Sunday.
