Warm, Dry Conditions Turn Up Heat in Pasadena

It’s about to get a lot warmer across the Southland as a high-pressure system and winds combine to drive temperatures upward into the weekend.

According to the National Weather Service, maximum temperatures “will be 10 to 15 degrees above normal through Saturday before a cooling trend begins Sunday.”

Temperatures already began rising Thursday, with forecasters saying most inland areas saw heat 10 to 20 degrees warmer than Wednesday, and even coastal areas were 5 degrees warmer than the previous day.

“Expecting more of the same through Saturday as light offshore flow to the east continues and high pressure aloft strengthens,” according to the NWS. “By (Friday) most valleys will warm up into the mid 80s to mid 90s and then Saturday a few degrees warmer still.”

Humidity levels will also drop into the 8% to 15% range during the day.

“The combination of wind and humidity will likely lead to localized two to four hours of red flag conditions each day,” according to the weather service.

Cooler conditions are anticipated for the first half of next week.
