DISCUSSION

Issued at 1030 PM EST Tue Feb 3 2026

A surface pressure ridge extending across the Florida Peninsula is maintaining light to gentle broadly northeasterly breezes along the Keys this evening. A warming and moistening trend continues along the Keys, but cool conditions remain. Temperatures are now in the upper 50s to near 60 along the Keys. Dew points jumped quite a bit in 24 hours, from the lower 30's to lower 50s. However, this evening sounding indicated a sharp and strong subsidence inversion around 850 mb with very warm and dry air above. Strong veering through the lower levels has contributed to an expansive swath of stratocumulus across extreme South Florida and the Keys this evening and skies are now mostly cloudy to overcast.

The ridging across Florida will maintain a light to gentle mostly northeasterly flow. While winds will try to veer further easterly, it is likely that the still very cool gulf and bay side waters will keep winds backed north to northeast. For example, Ocean Reef had shifted east northeasterly this afternoon, but has already backed just west of north. Meanwhile, winds at Carysfort Reef Light remains east northeasterly. The overcast skies will minimize the amount of nocturnal cooling. As a result, expect overnight lows to range in the mid to upper 50s, largely dictated by gulf and bay waters still in the mid 50s. Dew points may climb a bit into the mid 50s. Very stable conditions will continue and rain chances will remain nil.

MARINE

Issued at 1030 PM EST Tue Feb 3 2026

A pressure ridge stretching west southwestward across the Florida Peninsula is maintaining gentle northeasterly breezes on Keys waters this evening. Winds are a bit more veered east northeasterly to the south of the Keys. A subtle land breeze is expected to develop overnight and winds may pick up slightly in the predawn hours to a gentle to moderate breeze. No major changes planned for the evening marine update.
