Summer may be coming to an end, but a mid-summer-like blast of heat is hitting the Southland Wednesday, and it will persist into Thursday before a cooling trend begins.

A heat advisory issued by the National Weather Service for Pasadena will be in effect until 8 p.m. Wednesday.

The heat roller coaster will climb to triple digits Wednesday then plunge to 89 on Thursday, NWS forecasters said.

Conditions should change beginning Thursday, with a return of onshore flow and the arrival of a low-pressure system that will likely cool temperatures into Sunday.

Forecasters warned residents to take precautions if they are outside in the heat, such as drinking plenty of liquids, avoiding prolonged exposure to the sun and checking on vulnerable relatives and neighbors.
