Long Term
(Sunday through Thursday night) Issued at 403pm CDT Fri Nov 1 2024

The remainder of the forecast is a little more uncertain outside of drier conditions on Saturday. What happens is upper ridge to the east expands westward and slightly over the CWA (County Warning Area) Saturday. That'll drive the moisture plume currently over the CWA to the west and shut off rain chances. But then, an upper level trough digs across the Rockies and across TX early next week. That'll begin to erode the ridge and eventually leads to increased rain chances and moisture returns.

Marine
Issued at 403pm CDT Fri Nov 1 2024

The surface ridge centered in the western Atlantic that has been extended across the Gulf of Mexico will begin to shift eastward. Another surface ridge centered over the Great Lakes is beginning to expand southward in the wake of the one in the Atlantic. As this northern high pressure system slides east, it will continue to extend well into the Gulf of Mexico. That'll keep onshore flow established now through the middle of next week. Varying degrees of pressure gradient in that time may result in hazard headlines at times, including the current exercise caution in place over open Gulf waters.
