Hot and Dry Through the Weekend

The National Weather Service is warning of an “elevated fire danger ” over the interior areas of Southwest California including Pasadena, as an extended period of hot and very dry conditions continue through the weekend.

In a Hazardous Weather Outlook updated Friday morning, the NWS said there will be “heightened fire concerns today” due to the heat and low relative humidity.

Today, temperature highs will go up to 92 degrees, while the humidity will remain low at 42 to 49 percent through the weekend until at least Tuesday next week.

Gusty onshore winds will also push the hot and dry conditions further inland and add to the elevated fire danger.

“Brief critical fire weather conditions can be expected each afternoon across portions of the mountains, interior valleys, and deserts,” the NWS said.

The hot spell, which began in earnest Thursday, is the product of an upper-level high pressure system. NWS forecasters said the system “will produce temperatures in the 90s and low 100s in the valleys and at lower elevations in the mountains.”

For areas that experienced dense fog this morning, the condition is predicted to be repeated tonight after midnight.

Nights will continue to be warm with lows at 61 degrees tonight and about 64 degrees Saturday night.
