Fresno will reach 108 degrees Monday.
An Excessive Heat Warning for the San Joaquin Valley and Coastal Hills remains in effect until 8 PM Monday night. An Excessive Heat Warning means that a prolonged period of dangerously hot temperatures will occur. Heat related illnesses, such as heat exhaustion and heat stroke are likely if precautions are not taken. Drink plenty of fluids, stay out of the sun, and remain in an air-conditioned room. As always, never, ever leave a child or pet in an enclosed automobile.
Fresno reached a high of 103 degrees Sunday afternoon. It would have been warmer except for wildfire smoke in the air blocking some of the heating of the sun.
Monsoon showers and thunderstorms will return to mountain areas Monday afternoon. Beginning Tuesday, a change in the weather pattern allows cooler, cleaner air to enter the Valley from the west.
