The extremely warm thermal regime across the U.S. during 2024 continued in June. The month of June ranked 2nd hottest in 130-year history. Record heat was observed in Arizona and New Mexico. Near-record warmth was observed in California, Florida, Utah, Colorado, and Maryland plus all southern New England plus Maine. Only the northern Great Plains were near normal.

Beryl’s response to the anomalous warm SST during the early July trek was notable. First, Beryl became a hurricane once SST warmed to 84F in the central North Atlantic tropics. The earliest hurricane on record for this location was born as SST was much above the usual (for July 1) 81-82F SST for this region.

Heatwave conditions are likely to continue for Southwest Russia, the Black Sea region, and Southeast Europe. A dry regime is included in this hot zone. The hot weather is an extension to record heat of this week extending across Western Russia where many records were broken.

In the West, an expanding heatwave has developed. Excessive Heat Warnings cover most of California. The warning is valid through the weekend. Heat Advisories are posted for San Francisco and Los Angeles coastal areas. An Excessive Heat Watch is posted for Phoenix, AZ, Reno, NV, and Eastern Washington where excessive heat is likely to develop.
