FNUS54 KHUN 230911 FWFHUN Fire Weather Planning Forecast for Alabama National Weather Service Huntsville AL 411 AM CDT Sun Aug 23 2026 .DISCUSSION... Surface high pressure (centered across southern Canada) will have a dominant influence on local weather conditions from today through Monday, maintaining light northerly winds that will advect a drier airmass into the region (featuring MinRH values in the 35-45% range both today and Monday). Although a few light showers will be possible early this morning as a weak cold front shifts southward through the region, most locations will remain dry through Monday (when a few showers related to a southeastward moving complex of storms may clip portions of northwest AL). Smoke dispersion indices will be in the generally good-good range both days, with mixing heights of 6000-7000 ft and transport winds of 5-10 MPH. Fog potential over the next few days: Patchy fog may develop in wind-protected locations and near large bodies of water early this morning and again early Monday morning. Potential for Red Flag Conditions: None at this time.
