FNUS54 KMEG 222031 FWFMEG Fire Weather Planning Forecast for the MidSouth National Weather Service Memphis TN 330 PM CDT Sat Aug 22 2026 .DISCUSSION... A weak cold front has cleared the region and dropped relative humidity values into the lower 40 percent range across areas along and west of the Mississippi River, with this drier air filtering across the majority of the Mid-South. However, light surface winds, daily rain chances, and adequate overall moisture will keep critical fire weather concerns safely at bay. The combination of light overnight winds and clear skies will also create a potential for patchy fog during the early morning hours, particularly along low-lying river basins.
