SHORT TERM FORECAST

The 00z evening sounding displays a different look tonight compared to previous evenings. While most of the sounding does remain dry, there are some differences. The moisture continues to lower with the highest moisture being confined to the lowest few thousand feet of the atmosphere. The moist layer this evening was measured around 940-960 mb which is consistent with where observations have been reporting the ceiling height to be which is around 1500-2000 ft. The wind profile shows slight veering to the profile with 070 degrees at 1010 ft and then 085 degrees at 3000 ft. The PWAT value measured is also much higher compared to previous evenings measuring in at 1.12 inches. This value is a little below the median for the date. Overall, no changes expected to the ongoing forecast as we cannot rule out a stray shower or two overnight.

MARINE

Issued at 1010 PM EDT Fri Apr 17 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, high pressure over the central North Atlantic will start to loosen its grip across the Keys over the weekend. This will allow for slowly slackening breezes, potentially becoming variable sometime Sunday/Sunday night. A front approaches the Keys sometime Monday/Monday evening with a strong high pressure quickly filling in the wake on Tuesday. Fresh to strong breezes will prevail as early as Monday night, and hazardous marine conditions will continue through at least mid week.

AVIATION

(00Z TAFS) Issued at 1010 PM EDT Fri Apr 17 2026 VFR conditions are expected to persist through the TAF period at both EYW and MTH terminals. Occasional periods of MVFR CIGs cannot be completely ruled out overnight and during the day on Saturday. A passing brief shower also cannot be ruled out with the best chance being around daybreak Saturday.
