Long Term
(Wednesday night through Monday) Issued at 341am CDT Tuesday Mar 25 2025

Thu we should not see a lot going on other than the potential for fog. Fri we should start to see an MCS (Mesoscale Convective System, a complex of thunderstorms which becomes organized on a scale larger than the individual thunderstorms) feature move out of NE Mexico and move along the gulf coast. Some guidance would like to bring it to our doorstep by Fri afternoon, and this could be the case but we will need to see how models handle the timing of this system first or at least build a consensus. This could produce severe storms Fri into Sat morning from Texas into Louisiana. Just how far east will be the question though. Storm Prediction Center has our are in a slight risk for D7 at the moment which would not be this MCS feature but instead a cold front that moves into the area Monday. And this front could also spark severe storms with it. Spring is in full force with these systems, so we always have to stay alert even when model guidance fails.

Light and erratic winds will become northerly late today but still 15kt or less. East winds will develop by Thu into the end of the week with wind speeds rising to around 20kt. There is a potential for dense fog in the nearshore waters again tonight into Wednesday morning but its not high with the exception of the Miss River.
