Area Forecast Discussion National Weather Service Key West FL 1129am EDT Fri July 3 2020 Isolated air mass showers and a couple of thunderstorms will be the main forecast concern through Saturday. The 12z KEY balloon sounding shows that the air mass has moistened over the past 24 hours, with the PW value rising from 1.49" to 1.81". The latter value is near the daily mean for this date in the Storm Prediction Center sounding climatology. Have already had a few showers develop along the island cloud line over and Gulfside of the Lower Keys this morning. A few more cycles of cloud line development and decay are likely up and down the Keys until daytime heating over the narrow island chain eases early this evening. Marine An east-west surface ridge axis is located squarely across the Keys today, leading to light breezes of 5 knots or less. The ridge will settle south into the Straits over the course of this afternoon and tonight, leading to a turn to light westerly breezes this afternoon. Florida Bay and the far Upper Keys can get an acceleration of west winds during the late afternoon and early evening due to effects of daytime heating over the FL Peninsula, so that is the one places that could get a couple hours of gentle or even moderate breezes late today. Otherwise, the ridge axis will rest just to our south Saturday and Sunday, lifting back north across the Keys on Monday. During this time, only light and sometimes gentle breezes are expected. Nearshore waters will have lots of smooth, glassy periods. Climate On this date in 1957, the daily record high temperature of 95F was recorded at Key West.
