National Weather Service Key West FL
1049pm EDT Sunday May 22 2022

A strong surface high centered in the western Atlantic extends westward across Florida, resulting in moderate to fresh east to southeasterly breezes across the Keys and surrounding waters. To the west a trough remains aloft over the northern Gulf of Mexico. Evidence of the Saharan air layer was still present as seen by this evenings RAOB (Radiosonde Observation or Upper-Air Observation) launch along with a hearty cap based around ~900 mb. This inhibition layer has been sufficient to prevent just about any shower development across the Keys area this evening. Temperatures remain on the warm side with current temperatures in the lower 80s. In fact if the temperature here in Key West fails to fall below 82 degrees, we will tie the daily warm minimum temperature for May 22nd. Temperature records in Key West date back to 1873.

Short Term Update
The robust surface through lower level ridge will remain steadfast across Florida through the overnight period. As a result, winds will remain moderate to fresh out of the east to southeast. This will ensure that warmer than normal temperatures will persist through the overnight. Expect overnight lows will struggle to crack below 80. Unlike last night, dew points have fallen a few degrees and are now in the mid 70s and will likely hold as is. Rain chances will remain slim at best due to continued stable conditions. No changes requires for the ongoing forecast.

Marine
Moderate to fresh east to southeast breezes will persist through the overnight as a robust ridge sits across the western Atlantic. As such Small Craft Exercise Caution headlines will remain in effect for all waters through the overnight. Continuing from synopsis, high pressure centered just to the southwest of Bermuda will maintain fresh east to southeast breezes across the coastal waters of the Florida Keys through at least mid week. Breezes will begin to diminish Thursday as the high recedes to the northeast and further into the western North Atlantic, leaving gentle to occasionally moderate southeast winds by the end of the week.

Climate
In 1997, an F1 tornado produced $150k in damage around mm 58.5 on grassy key. The local climate report for that year indicated it was an F0 with no injuries or fatalities and "only minor damage".
