National Weather Service Key West FL
1040am EDT Sat May 21 2022

A breezy and humid day is underway across the Florida Keys. Winds are 15 to 20 knots along the Reef, with temperatures climbing through the 80s along the island chain. Dewpoints remain solidly in the mid to upper 70s. The KBYX radar is echo free and skies are partly cloudy. There is a noticeable milky haze across the Keys, which is likely the remnants of the SAL. Steep lapse rates were sampled by the 12Z KKEY RAOB (Radiosonde Observation or Upper-Air Observation) from 850-600 mb, lending to lots of ML CAPE, but very little chance of breaking through the inhibition at the base of the subsidence. The forecast calls for 10% rain/thunder chances through the afternoon which is right on track in our assessment.

Marine
Small Craft Should Exercise Caution due to east to southeast winds 15 to 20 knots. Portions of the Upper Keys are near 15 knots, while locations near Key West average just under 20 knots, with frequent gusts in the low 20s. Any increase in wind speeds, and a Small Craft Advisory will be required. From synopsis, high pressure will build over the western Atlantic today into tonight, bringing fresh to strong east to southeast breezes to the Keys coastal waters. The high will weaken slowly from Sunday through the middle of next week, with moderate to fresh east to southeast breezes prevailing across the Keys waters.

Climate
On this day in Keys weather history In 1935, the daily record high temperature of 91F was recorded at Key West International Airport. Temperature records date back to 1873 in Key West.
