A “strong and expansive upper level ridge” is expected to bring unusually warm temperatures across much of the western half of the United States this weekend, the National Weather Service Prediction Center reported.

Several temperature records were broken Tuesday, including some that are almost a century old, according to the National Weather Service.

A high pressure area expected to intensify offshore in recent days is expected to keep temperatures into the 70s and 80s, with temperatures 18 degrees above normal by Wednesday, according to the National Weather Service.

Süß said temperatures throughout the southern state were 15 to 20 degrees above standard, and that Wednesday should become even warmer than normal.
