Long Term
(Friday and Beyond) Issued at 442am CDT Wednesday September 28 2022 Ian will help keep a stacked northerly flow over the area which will continuously bring dry dew pts in through the weekend. This will help keep the area with little to no mention of rain for the next several days. We are in a transition time as we enter October. This transition from easterlies to westerlies is climatologically what causes this dry period for about a month give or take. But conditions are normally quite nice during this time of year. But they do promote a fire danger when winds get high enough to help the rate of spread. There is a slight chance for some of the wet stuff by the start to middle of next week but this may be very low or non-existent.

Marine
Issued at 442am CDT Wednesday September 28 2022 Due to Hurricane Ian, the coastal waters continue to see periphery impacts, primarily with hazardous winds and swells. Strong winds continue, especially the eastern half closer to Ian where the pressure gradient is stronger. Appropriate headlines have been issued, with a small craft advisory for the tidal lakes, and gale warning for the sounds through the open gulf. Winds will begin to slowly taper down starting tomorrow but will be a slow process. Small craft advisories will likely be needed after the gale warning. Winds will finally begin to lighten near the end of the week into early next week. -BL
