014 FNUS52 KKEY 240844 FWFKEY Fire Weather Planning Forecast for the Florida Keys National Weather Service Key West FL 444 AM EDT Sun Aug 24 2025 .Discussion... A weak subtropical high pressure ridge will dominate the pattern for the remainder of the weekend continuing into the middle of the week. This will result in mainly light to gentle breezes, occasionally becoming variable. Moisture remains plentiful for the remainder of the weekend and into early week with the main triggering mechanisms being outflow boundaries colliding with residual boundaries from earlier convection and other mesoscale processes. Therefore, expect rain chances of 30% for today and 20% for tonight through early week as slightly drier air moves in. Min RH values are expected to be in the mid 60s percent today and Monday with good RH recover to the lower 90s percent tonight.
