FNUS52 KKEY 240848 FWFKEY Fire Weather Planning Forecast for the Florida Keys National Weather Service Key West FL 448 AM EDT Fri Jul 24 2026 .Discussion... Temperatures will be closer to normal today, thanks in part to an easterly wave passing through the area today. This feature will continue to support elevated rain and thunder chances for today, especially this morning. As this feature exits to the west, winds will be slackening through Saturday, and may result in winds becoming light and variable at times. This will result in poor dispersion indices. Expect afternoon min RH values to hold around the mid 60 percentile and recover to near 90 percent overnight.
