First heat wave of summer looms


Temperatures are forecast to be in the triple digits for the next 10 days. Highs should range from 100 to 105 throughout the period. A 40 percent chance of a thunderstorm in Three Rivers is predicted for Thursday.

Monsoonal moisture will make its way northward from Baja California, bringing unstable weather across the Sierra Nevada with each day featuring a buildup of thunderheads as moisture increases. The tropical moisture will fill in during the weekend between low pressure offshore and high pressure parked over the Great Basin.

It’s not uncommon to experience triple digits in June. It is, however, unusual for the run of consecutive triple-digit days to last more than a week. The mean high temperature of 105 degrees is short of the daily all-time record but the run of consecutive days in triple digits may be the longest ever in June for Kaweah Country.

High temperatures in the nearby mountains above 7,500 feet will top out around 80. Nighttime temperatures will dip into the refreshingly low 50s.  

The local cooling center for those who need to come in out of the heat is Three Rivers Library.

Due to the extreme fire danger in Three Rivers, the surrounding foothills, at Lake Kaweah, and in Sequoia-Kings Canyon National Parks, FIREWORKS ARE ILLEGAL in these areas. 

Because of the prescribed fire in Sequoia National Park this week and high pressure parked over the region, the air quality in Three Rivers climbed as high as Level 4: Unhealthy.
