DISCUSSION
Issued at 349 AM EDT Thu May 22 2025
It's another quiet, dull, but sultry early morning for the Florida Keys. Temperatures as of 3 AM are in the lower 80s with dew points in the mid to upper 70s (yuck). After a brief surge from the north in the late evening, winds have quickly settled down and becoming variable. As alluded to, the KBYX radar remains rain free this morning. Meanwhile, a weak frontal boundary currently draped across the Panhandle of Florida is slowly trudging southward this morning.
Said front will continue to slowly move southward today, only reaching south central Florida by this evening. In the meantime, as it approaches the region, it will help to maintain the col already in place due to a lack of any synoptic features. As such, we can expect another light and variable day along with daytime temperatures in the mid to upper 80s and dew points in the mid 70s. There is a chance we may see some relief from the heat today. Given the light and nebulous flow that will sit across the Keys, we could see a brief reverse cloud line attempt to develop in the late morning and afternoon. Looking at last evening's sounding, there remains an inversion around 750 mb, but there was still decent MLCAPE present in the layer. If we can overcome this inversion, we could see embedded showers and isolated thunderstorms within the cloud line. Unfortunately, given that it will be a reverse cloud line, it means that Key West may miss out on this one.
The aforementioned frontal boundary will stall just north of our area and gradually dissipate overnight into Friday. This will mean one more day of light and variable winds. As the next low level ridge settles in across the Southeast U.S. and slinks into the southwestern North Atlantic, breezes will decidedly clock around from the east. This will usher in better moisture and rain chances will return closer to, if not slightly above our climatological norm. The ridge looks to hold in place well into the new work week and we can expect a little more active weather pattern next week.

AVIATION
(06Z TAFS)
Issued at 349 AM EDT Thu May 22 2025
VFR conditions continue to prevail at both EYW and MTH through the TAF period. Transient short-lived bouts of MVFR CIGs are possible at times, but these should not be significant enough to warrant TAF mention. Likewise, a slight (10%) chance of showers and thunderstorms exists for the region after sunrise this morning, but the timing and coverage of any showers that occur is uncertain enough to leave for later TAF cycles and amendments. Surface winds remain light and variable through the TAF period.
CLIMATE
On this day in 1997, an F1 tornado produced $150,000 in damage around mm 58.5 on Grassy Key.
