Temperatures are set to rise across Los Angeles and parts of the southwestern U.S. later this week.
Extreme heat is already settling across Southern California and Arizona as readings threaten to reach 116F (47C) across the region, including in Palm Springs and Phoenix through Thursday, according to the National Weather Service.
A heat advisory will also take effect Thursday across parts of Southern California, including Los Angeles and Burbank, the agency said. Temperatures in downtown Los Angeles are forecast to peak around 87F Thursday, while Burbank may reach 92F. Meanwhile, New York City’s Central Park will see 74F Tuesday with a chance of showers.
The warnings and advisories come as forecasts point to a broader heat wave taking shape across the US West and South, with temperatures expected to run 3F to 5F above normal across the Rocky Mountains through Saturday, according to commercial forecaster Commodity Weather Group.
The longer outlook calls for a moderate risk of extreme heat from Southern California to Florida, including Texas and its weather-battered grid ERCOT, from July 14 to 20, the US Climate Prediction Center said late Monday. While most of the western and southern US have a greater than 50% chance of seeing above normal temperatures, Southern California around Los Angeles, the northern Rocky Mountains and most of Florida have an even higher chance.
Back in New York and New England, temperatures are expected to remain closer to seasonal norms, although Central Park could briefly reach 88F with thunderstorms Friday.
