DISCUSSION
Issued at 957 PM EST Fri Jan 16 2026
The robust surface high that brought in the cold airmass after yesterday's cold front is now driving northeastward off the Carolina Coast. As a result, winds have been able to uncharacteristically shift broadly easterly. Interestingly, this has helped to drive temperatures upwards in recent hours. After slipping into the mid to upper 50s this afternoon and evening, temperatures have bumped upwards into the mid 60s. Portions of the Keys may still see temperatures slip below 60 as a mainland land breeze is expected to push south southwestward across at least the western half of the Keys. Skies will remain a mix of partly to mostly cloudy due to excellent lower level veering and an easterly steering flow driving an extensive stratocumulus field across the island chain. Rain chances will be slight at best and generally be best characterized as very light and unlikely to measure.
MARINE
Issued at 957 PM EST Fri Jan 16 2026
The high cell that recently helped to blast a strong cold front across the area is quickly lifting northeastward into the Atlantic. This has resulted in winds relaxing to light to gentle and shifting northeast to easterly. The probability is high that winds will back north northeasterly for a sizable portion of our waters, mainly in the lee of South Florida due to
AVIATION
(00Z TAFS) Issued at 957 PM EST Fri Jan 16 2026
VFR conditions will prevail at the island terminals overnight. Expect VFR based stratocumulus ceilings based between 4000 and 5000 ft. Surface winds will be light to gentle out of the northeast to east. A subtle north northeasterly surge to 10 to 15 knots is likely late in the overnight period due to a mainland land breeze.
