A high-pressure system over the central San Joaquin Valley continued to heat the region Monday, bringing near-record temperatures to the area.
Fresno’s high Monday hit 94 – one degree short of the record set in 1964. Tuesday’s high is expected to hit 93, just short of the record of 95 set in 1991, the National Weather Service says.
On Saturday, Hanford set a record of 100 degrees, breaking the old record of 93 set in 1999. On the same day, Madera tied a record of 95 set in 1999. Fresno’s high of 97 was 2 degrees below the record of 99 set in 1991.
The weather service says the high pressure will begin to break down by mid-week and a weather system moving north from Baja California will bring a chance of showers and thunderstorms to the region by Wednesday.
