Boise broke a 134-year-old record-high temperature by two degrees on Sunday.
The National Weather Service in Boise recorded a high of 97 degrees Fahrenheit, beating out 1882’s record of 95 degrees. Metereologist Bill Wojcik attributed the sweltering heat to an “unusually strong high pressure ridge.”
While the average for this time of year is in the high 70s, Wojcik said Monday’s record high is 101 degrees, while Tuesday’s is 100 degrees. The Treasure Valley will continue to see mid-90s temperatures through Wednesday, when a projected high of 94 degrees could contest the record of 96 degrees.
After Wednesday, Wojcik said, the area will cool down with a low-pressure system, decreasing into the 80s toward the end of the week and into the low 70s by next weekend.
