FNUS52 KKEY 020841 FWFKEY Fire Weather Planning Forecast for the Florida Keys National Weather Service Key West FL 441 AM EDT Thu Jul 2 2026 .Discussion... The forecast remains overall unremarkable with typical summertime hot and muggy weather in place. Minimum RH values anywhere from 60% to 70% will recover to 80% to 90%. Widespread, drenching rainfalls are unlikely due to a lack of a larger scale lifting mechanism, but afternoon cloudlines along the island chain as well as the usual afternoon convection over the mainland will be enough to trigger some showers and thunderstorms. Light and variable winds in the lowest levels of the atmosphere will keep dispersion index values around very poor.
