.DISCUSSION...
Issued at 1054 AM EDT Fri Apr 19 2024
Subtle changes were sampled in this morning`s 12z sounding at KEY,
indicative of a evolving (albeit very slowly) pattern for the
Florida Keys. The low-level temperature inversion that has been
based around 900 mb has lifted to around the 850 mb isobaric
surface. The profile has moistened below this capping inversion,
and 0-3 km winds are now displaying modest veering with height.
Light, northeasterly surface winds will be supportive of a
potential broken cloud line today, which will be monitored. Our
in-house waterspout index reflects this, coming in at 6% for the
12z, a bit higher than climatology for this time of year.
Temperatures will nudge up a few more degrees, topping out in the
mid 80s. Outside of removal of transitional wording for afternoon
slackened late morning and afternoon wind speeds, no changes
required at this time.
