Marine
.SHORT TERM... (Today through Wednesday night) Issued at 200am CDT Monday April 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.

Long Term
(Thursday through Monday) Issued at 200am CDT Monday April 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 probability of precipitation 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.

Marine
Issued at 200am CDT Monday April 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 heigheights 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 heigheights 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.
