Recent extreme heat across the Southwest, including daily records in Phoenix, Palm Springs, and Death Valley amid a persistent heat dome, has kept the market split between low and moderate-to-high ranges of all-time station records for August. July’s unprecedented national heat produced hundreds of all-time highs, raising baseline expectations, yet August’s activity appears more localized and less likely to eclipse prior station maxima at scale. Cooling trends emerging by month’s end and the distinction between daily versus all-time records create the tight contest, with further verification of final NOAA tallies or additional late surges capable of shifting probabilities sharply toward one outcome.
