KEY MESSAGES

- Conditions will be marginally conducive for a reverse cloud line to develop Friday afternoon. - Light and variable winds will persist into Friday.

DISCUSSION

Issued at 1116 PM EDT Thu Jul 30 2026

Another afternoon, another late day cloud line. This one was way less impressive than the one that developed yesterday, though it did manage to produce some showers before quickly fizzling out. Since then the radar has been void of any precipitation echos. Meanwhile, the pressure field across the Keys continues to become weaker and more nebulous. This is resulting in slackening winds with winds becoming light and variable.

Winds will remain light and chaotic Friday into the first half of the weekend. Starting Sunday, a large surface low will slowly meander eastward from the Mississippi Valley and settle across the eastern half of the U.S. This will tighten the pressure gradient and lead to an increase in winds. In addition, moisture will gradually begin increasing across the region, setting up for a potentially wet pattern early next week.

MARINE

Issued at 1116 PM EDT Thu Jul 30 2026

Winds have gone light and variable this evening and will continue through the overnight and into the first half of the weekend. The exception will be the waters immediately adjacent to the mainland which will briefly freshen to light to gentle in the afternoon. Starting Sunday, a large surface low will move into the eastern U.S. and gradually tighten the pressure gradient across the region. This will lead to freshening east to southeast breezes into early next week. In addition, there is a potential for a return to a more active weather pattern.

AVIATION

(00Z TAFS) Issued at 1116 PM EDT Thu Jul 30 2026

VFR conditions expected through the forecast period with light and variable winds generally expected. Conditions are very marginal that a cloud line could develop in the afternoon.
