Perfect example of the urban heat island effect.
As urban area as encroach on temperature stations, the recorded temperature rises. To give a truer picture we have both the USCRN and satellite temperature measurements. The United States Climate Reference Network (USCRN) is a sustained network of high-quality weather monitoring stations across the contiguous U.S., Alaska, and Hawaii.
Now keep in mind that the 2023 peak was influenced by the eruption of Hunga Tonga, which spewed megatonnes of water vapour into the atmosphere. Water vapour is the most potent greenhouse gas. Fortunately it will dissipate over the next few year and well be back to a very gradual rise.
No need to panic.
