137 pm edt Tue sep 17 2019

Short term
An upper-level ridge that has been created in part by humberto and a
tropical wave in the western gulf will be replaced by a positively
tilted upper-level trough axis as it dives southward. This trough
will serve to filter "cooler" and drier air into the area beginning
late tomorrow night.

For this afternoon evening, however, humberto continues to influence
our weather as the cyclonic (clockwise) flow brings drier,
continental air over the region. This is not unlike conditions for
the rest of the week, but the more comfortable conditions are still
trapped to the north of the peninsula. Complements of diurnal
heating, lack of rain, and fewer clouds, temps are expected to reach
the low-to-mid 90s for almost everywhere except the immediate coast
between now and roughly 5pm. Unlike last week where high humidity
combined with higher temperatures reached heat advisory criteria,
the drier air should keep temperatures feeling closer to the actual
value. It will still feel hot, but not as hot as last week.

Thankfully, conditions will begin to transition tomorrow as the
front makes it way through the area. A few showers are possible
across the region, particularly tomorrow afternoon evening.

Temperatures will respond to this change on Thursday with highs
reaching the mid-to-upper 80s as opposed to the lower 90s. The
humidity levels will be the most noticeable difference, with
conditions feeling more comfortable beginning Thursday. Winds will
also increase with a tighter pressure and thermal gradient across
florida. Overall, Thursday will be a nice day across the region.

Long term
Conditions will gradually return to a late summer pattern through
the weekend and into next week. A tropical wave passing through the
florida straights will also facilitate the return of moisture to
southern portions of the peninsula. There are noticeable
discrepancies at this point in the forecast between the global
models, with the precipitation parameterization schemes
struggling to determine the northward exentent of the
precipitation. However, there has been a northward trend in
precipitation over the last couple cycles and this may continue.

Overall, conditions are expected to warm up and humidity moisture
levels will begin to return early next week.

Aviation
Vfr conditions are expected through the forecast period. Winds will
become light and variable overnight and then light northeast on
Wednesday.

Marine
Light northerly winds and fairly calm seas will remain through
tomorrow evening. A round of showers are possible tomorrow night
across offshore waters as a passing front pushes through. This front
will lead to increasing winds and seas Wednesday night into
Thursday. By Friday, winds and seas will be approaching cautionary,
then advisory levels in offshore waters. Winds and seas will
gradually settle down through the weekend. Mariners planning to boat
on the eastern gulf later this week should monitor the latest
forecast for updates on these anticipated rough conditons.

Fire weather
Conditions will begin to dry out the remainder of this week. Aside
from some low rain chances Wednesday afternoon evening, little-to-no
rain is expected for the next several days. While drier
comparatively to what has been the typical weather for the last few
months, conditions are expected to remain above critical levels.
