A warm, moist air mass will persist across the Florida Keys today,
with increasing southwest winds. For tonight, we expect a chance
of showers and slight chance of thunderstorms ahead of an
approaching cold front. The front should sweep through overnight,
accompanied by a northwest wind shift, with clearing and breezy
conditions developing on Wednesday. Relative humidity values will
remain high through early Wednesday, then drop rapidly Wednesday
