NEVADA COUNTY, Calif. — Temperatures in the triple digits are a possibility this week in the western part of Nevada County, according to the National Weather Service.

A high-pressure system over the region is the reason for the above-average temperatures, which are forecast to reach 10 to 13 degrees over the norm, said Jason Clapp, meteorologist with the weather service.

“You guys are right around the century mark, which is significant,” Clapp added.

Temperatures in the Sierra Foothills will creep closer to 100 Tuesday and Wednesday, hitting triple digits Thursday and Friday before falling slightly over the weekend.

Meanwhile, in the Truckee area, a high temperature of 89 degrees is forecast Tuesday, with temps between 90 and 93 degrees on tap for Wednesday through Friday, according to NWS.

At Lake Tahoe, temps are expected in the upper-80s all week. Low temps in Truckee, meanwhile, are forecast to be in the 40s this week.

A different weather system with cooler air moving into the state will cause the slight temperature drop by pushing the high-pressure system away, Clapp said.

Average temperatures in July for Grass Valley hover around 87. Average temperatures for Sacramento are 94. The capital will see highs hitting 106 this week, Clapp said.

There’s no chance of rain for Nevada County in the near future, he added.

The higher temperatures and lack of humidity also bring fire concerns, the weather service states.

Joanne Drummond, executive director of the Fire Safe Council of Nevada County, advised people avoid using steel-bladed motors when clearing defensible space and instead use a string motor. Work should be done before 10 a.m., before temperatures begin their climb.
