(Thursday through next Monday) Issued at 203 PM EDT Mon Mar 18 2024 The influence of high pressure will diminish and move off to the east on Thursday with chances for showers and thunderstorms increasing on Friday as instability associated with a low pressure system traveling across the Gulf of Mexico and then being followed by a dry front bringing high pressure conditions over the forecast area by the end of the weekend. Temperatures will drop to be slightly below the seasonal average by the end of the week but will return to normal levels by the end of the weekend. && .AVIATION...

Generally looking at winds northwest at 15G25kt for the time being. The winds will diminish within a couple of hours of sunrise.
