New SHORT TERM, LONG TERM, MARINE

SHORT TERM
(This evening through Tuesday night)
Issued at 236 PM CDT Mon Apr 29 2024

A line of storms moved through our area this afternoon, and a wake low developed on the backside. As a result, short-term enhanced winds 25-35mph with frequent gusts up to 40-45mph are possible through 1AM CT. These enhanced winds will subside when the low moves eastward out of our area late tonight into tomorrow morning. A wind advisory is in effect for the entire land area as this enhanced low pressure moves eastward. Secure any tents and loose items and be cautious if driving on elevated roadways.

Additionally, coastal flooding is ongoing for the MS sound areas with high tide expected in the next couple of hours. A coastal flood advisory is in effect until 7PM this evening. As winds shift westerly tonight, the impacts will subside and tomorrow's high tide is forecast to be around 3ft, which should not have impacts, based on local thresholds. We do not expect coastal flooding issues to continue beyond tonight.

Tomorrow morning through Wednesday morning, westerly shifting to southerly winds will help to keep humidity a little lower for the morning hours, but reintroduce moisture for the afternoon and evening hours. High temperatures tomorrow will be in the low to mid 80s with lows in the mid 60s. Looking at the models, rain is not expected tomorrow. MSW

LONG TERM
(Wednesday through Sunday night)
Issued at 236 PM CDT Mon Apr 29 2024

Generally in the long term forecast, conditions will be fairly dry Wednesday through the end of the week as several shortwave systems approach central Louisiana before being pulled back northwestward before reaching our area. There is a system at the end of the week on Friday, which could bring some rainfall to our area, but it would mostly be for our northern areas. The details surrounding this system, like amounts and strength, are still very uncertain and it may slide north of our area completely. We will be monitoring for changes as these systems develop over the next week. MSW

AVIATION
(18Z TAFS)
Issued at 1233 PM CDT Mon Apr 29 2024

MVFR conditions prevail at all area airports. A line of storms is moving through the area, approaching the LA/MS state line. These storms will continue to progress eastward through the afternoon hours. Temporary periods of IFR conditions are possible, during the afternoon as showers move through the area. Conditions at all area airports will improve to VFR conditions tomorrow late morning through the afternoon hours and persist through the end of the forecast period. MSW

MARINE
Issued at 236 PM CDT Mon Apr 29 2024

As the line of storms moved through this afternoon, a wake low developed and is moving across our area. As a result, short term enhanced winds are expected through 1AM CT tonight. Generally, southeast winds 35-45kts with locally higher gusts are possible and a Gale Warning has been issued for all of our marine areas.
Once the higher winds have subsided, westerly winds and moderate winds (10-15kts) will prevail Tuesday. Southeasterly moderate (10-15kts) winds and benign marine conditions will be in place for the rest of the forecast period. MSW
