Discussion
Typical summertime pattern remains in place today and will
continue into the weekend. Surface ridge placement will keep the
area in a light southeasterly flow regime though the weekend and
into early next week. With ample moisture in place scattered
diurnal showers and storms can be expected each day. During the
start of the upcoming week, aloft, upper-level ridge moves out in
response to a deepening trough over the northeastern CONUS on
Monday and Tuesday. This will allow the surface ridge to retreat
out into the atlantic some ushering in more of a southwest flow to
round out of forecast period. This will push the gulf coast
seabreeze in early in the day which should keep highest rain
chances east of i-75 for the start of next week. Temperatures
through the period will remain near to a few degrees above normal
with highs in the lower to mid 90s.

Aviation
Much like the past few days, light southeast winds can be expected
early with a seabreeze turning winds onshore near coastal terminals
in the early afternoon. Similar to yesterday, scattered showers and
storms will develop along afternoon sea breeze boundaries. Expect
predominantlyVFR conditions with a good chance of some intermittent
MVFR ifr lifr conditions after 18z in and around thunderstorms. No
tempo groups included at this time due to timing and location
uncertainties but will likely be needed for subsequent forecasts.

Marine
High pressure remains over the area producing pleasant boating
conditions over the gulf coast waters. Winds remain 10 knots or less
through the period with seas less than 2 feet. The only hazard will
be with isolated storms and enhanced sea breeze winds along the
coast each afternoon evening. No other marine impacts expected.

Fire weather
Sufficient low level moisture will keep relative humidity values
above critical levels through the week with no red flag conditions
expected. No significant fog is expected through the period.
