DISCUSSION
Issued at 949 PM EST Thu Jan 22 2026 Weather has been mostly uneventful this evening as a mix of clouds and sun lingered across the area. Our KBYX remains down for maintenance at this time, but our neighboring KAMX radar in Miami has spent the evening monitoring light to moderate shower activity near the Middle and Upper Keys. Automated surface observations didn't report rainfall, but a few raindrops could be seen on Florida DOT traffic cameras around Key Largo. Various satellite bands have shown cloud cover waxing and waning across the forecast area, and this is expected to continue into the overnight hours. Temperatures are currently near 70F with dew points only a couple of degrees behind that, so the air feels a little on the damp side of things. Overall, things are uneventful along the island chain, and the current forecast continues this into the overnight. No updates or changes are warranted at this time.
MARINE
Issued at 949 PM EST Thu Jan 22 2026 There are no watches, warnings, or advisories in effect for the Florida Keys local waters. From synopsis, gentle to moderate northeasterlies will persist across the nearshore and offshore waters through the end of the work week. Shower coverage will diminish tonight as winds aloft direct a plume of moisture away from the Keys. Over the weekend, breezes are expected to slacken to light to gentle. A strong winter storm developing over the southeastern United States is responsible for weakening the pressure gradient, and a cold frontal passage associated with this system is expected sometime Monday to Monday Night. Winds will rapidly clock north and freshen to fresh to strong in its wake.
AVIATION
(00Z TAFS) Issued at 949 PM EST Thu Jan 22 2026 VFR conditions will prevail at both island terminals through the 00Z TAF period, and weather conditions are expected to remain dry. North to north easterly breezes of 5 to 10 knots will continue, and may veer more toward the east near the end of the TAF period.
