.SHORT TERM...
(Today through Wednesday night)
Issued at 200 AM CDT Mon Apr 22 2024

With the front well into the central Gulf of Mexico, we are now
in the dry period of our forecast. High pressure will be the main
factor influencing our weather through the middle of the week with
clear skies and calm conditions. 

Cold air advection will bring temperatures well below average
with highs 5 to 10 degrees below normal last night. Highs today
will be cooler than normal, with highs only in the low to mid 70s.
This will be the last cool day for the foreseeable future, as
consistent warm air advection will cause our temperatures to 
slowly rise for the rest of the week.

(Thursday through Monday)
Issued at 200 AM CDT Mon Apr 22 2024

The forecast period will begin with rather warm and humid conditions
as high pressure at the surface off the southeast US coast will
ridge into the forecast area. Meanwhile, low pressure will develop
east of the Rockies. This will allow southerly breezes to bring in
low level warm and moist Gulf of Mexico air.

This set up will continue into the weekend allowing the southerly
flow to persist. The southerly winds will become quite breezy as a
series of deep surface lows develop east of the Southern Rockies
increasing the gradient. Sustained winds could be around 20 mph with
gusts up to 30 mph and nearing potential wind advisory criteria
starting Friday through Sunday.

Despite ample low level moisture, ridging aloft is expected to keep
the atmosphere capped, with the storm track well to the north of the
forecast area through Saturday thus keeping pops out of the forecast
during that time frame.

By Sunday afternoon, the upper level ridge looks to shift a little to
the east that would allow for a frontal system to near the forecast
area from the northwest. This will bring about a slight chance for
shower and thunderstorm activity.

(12Z TAFS)

High pressure is setting us up for a clear day with VFR conditions
through the TAF forecast. Winds will weaken through the day
becoming light and from the north.

.MARINE...
Issued at 200 AM CDT Mon Apr 22 2024

Breezy offshore winds will continue to create hazardous conditions
for small craft through this morning. Winds will rapidly decrease
during the morning as the front continues to move south and
weaken. Rough seas will continue with the strong winds with
altimeter showing maximum wave heights around 7 feet. By this 
afternoon, winds will decrease rapidly, staying offshore, but 
weakening down to 10 knots. Waves will also decrease with the maximum wave
heights dropping down to around 4 feet.

Based on the current wind direction, a low water advisory is
unlikely, but water levels will be monitored until winds weaken.

Starting tonight, winds will shift, becoming onshore but remaining
light through the rest of the week.
