KEY MESSAGES

- Breezes will be gentle to moderate over the next few days, peaking in the evenings, and lulling during the day.

- Temperatures will gradually warm, returning closer to normal towards the end of the work week, and slightly above normal this weekend.

- Nil rain chances are expected for the next several days as dry air remains entrenched across the Keys.

DISCUSSION

Issued at 1035 PM EST Mon Feb 9 2026 Another uneventful evening rolls on for the Florida Keys. Cloud cover from early in the day has deteriorated considerably leaving a familiar picture of clear skies across the island chain on GOES-19 Nighttime Microphysics imagery. This also means that KBYX is clear of precipitable echoes currently and has been overall throughout today. While all of our offshore marine observations note winds blowing generally out of the east, a disparity in magnitudes exists north and south of the Keys with moderate breezes along the Reef and gentle breezes the shallow Gulf waters. Meanwhile, temperatures on land are a touch warmer than yesterday around this time with temperatures broadly in the 60s with dew points in the upper 50s.

No substantial change is expected in the short term as our synoptic players remain the same. High pressure congealed over the southeast US will gradually meander into the western North Atlantic but remain nosed over the Florida Peninsula promoting prevailing eastern breezes through tomorrow. These breezes will tend to wax overnight and wane during the day with diurnal influence. This evening's KKEY 00z sounding is also similar to 24 hours ago with an inversion just below 850 mb and dry air aloft resulting in a PW below the 25th percentile for today. CIMSS MIMIC PW indicates values below 1 inch surrounding the Keys as well as further upstream. Thus near nil rain chances will continue moving through the work week.

MARINE

Issued at 1035 PM EST Mon Feb 9 2026 No watches, warnings, or advisories are in effect for the coastal waters of the Florida Keys. From synopsis, mostly gentle to moderate breezes will persist as high pressure dominates the weather pattern over our local waters. The exception will be across the cooler, shallower waters north of the island chain, where breezes will be light to gentle. Meanwhile, a broad surface high pressure extends along the entirety of the Eastern Seaboard and is in the process of becoming disorganized. A new surface high will consolidate off the Southeastern U.S. coast Tuesday and slowly meander east out across the Atlantic. This will maintain a waxing and waning of breezes today through at least Wednesday. Towards the end of the week, the high will flatten across Florida, leading to a brief period of light and variable breezes.

AVIATION

(00Z TAFS) Issued at 1035 PM EST Mon Feb 9 2026 VFR and dry conditions will prevail at both EYW and MTH tonight. Near surface winds will be generally out of the east at 5 to 10 knots.
