.NEAR TERM [Through Tonight]...
Rain chances should diminish through the overnight hours across
the region as diurnal support dwindles. ECAMs are suggesting that
increased storm activity will develop in our southern and western
coastal waters tomorrow morning and continuing through the
afternoon. This is supported by weak surface to mid-level
convergence as a boundary develops across this region overnight.
With high dewpoints and practically saturated forecasted
soundings, it won't take much for storms to develop across this
region. Some storms may impact coastal regions; however, chances
significantly decrease across interior regions.

.SHORT TERM [Sunday Through Monday Night]...
Upper ridge centered along the northern Gulf Coast will remain
in place through Monday, keeping the very hot and humid conditions
in place. Low-level westerly to west southwesterly flow will keep
surface dewpoints quite high, with temperatures rising into the
mid 90s. Weak disturbances in the northwesterly flow aloft will
help to trigger scattered thunderstorms each afternoon.

However, before those storms develop, heat indices will rise
above 105 in most locations and approach 110 in a few spots on
Sunday. The highest values are most likely across the Florida Big
Bend into far southern Georgia. By Monday, values approaching
Heat Warning levels (113+) are not out of the question.

To limit the risk of heat related illness, drink plenty of water,
stay in air conditioned locations, and limit outdoor activities.
The risk of heat related illness will be greater for those without
air conditioning, especially the elderly, infants, and pets.
Those with health conditions and outdoor workers are also at
greater risk.

.LONG TERM [Tuesday Through Saturday]...
Upper ridge is expected to hold on through Tuesday, keeping
temperatures above normal and heat indices near or above advisory
levels. By Wednesday, the ridge is forecast to break down as a
trough digs into the eastern CONUS. This should put an end to the
extreme heat and lead to some above normal rain chances through
the end of the work week as a weak surface trough stalls near the
forecast area.

&&

.AVIATION...
[Through 18Z Sunday]
VFR conditions are expected through the evening; however,
SHRA/TSRA is expected to develop later this afternoon at all
terminals with roughly 30-45% POP chances across the region.
Outside of convection, VFR conditions are expected. Winds will be
remain light and out of the west southwest. Overnight and into the
morning hours, TLH and VLD will have higher chances for low vsbys
down to MVFR and possibly brief IFR conditions as patchy fog
develops.

&&

.MARINE...
Westerly flow is forecast to continue for much of the upcoming
week, with winds and seas remaining below headline criteria
outside of scattered showers and thunderstorms.

&&

.FIRE WEATHER...
Red flag conditions are not expected for the next several days with
relative humidity values remaining above critical levels.

&&

.HYDROLOGY...
Rain chances will begin to increase by the middle of next week.
The above average rain chances may mean a more widespread coverage
of 2+", but flooding is not expected.
