FNUS52 KKEY 280858 FWFKEY Fire Weather Planning Forecast for the Florida Keys National Weather Service Key West FL 458 AM EDT Thu May 28 2026 .Discussion... Moisture has increased substantially across the area, and rain and thunder chances will be at their peak today. However, chances for rain will trend slightly downward after today due to some relatively drier air near the surface combined with a lack of any meaningful lift. Even without showers, minimum relative humidity values during the day will be close to 70 percent, and will see excellent recovery to near 100 percent overnight. Winds in the lowest levels of the atmosphere will remain light to gentle, but any stronger showers and thunderstorms will result in periodic gusty and erratic winds.
