Area Forecast Discussion National Weather Service Huntsville AL 200 PM CDT Mon Aug 18 2025 ...New NEAR TERM... .NEAR TERM... (Tonight) Issued at 200 PM CDT Mon Aug 18 2025 Under the influence of sfc high pressure, our area remains dry today with very low chance (less than 10%) of any shower development this evening. Fog development should be limited to along rivers and in sheltered valleys as winds remain light with mostly clear skies. Low temperatures are forecast to drop into the low to mid 70s, which is not much relief from the daytime highs in the 90s we continue to experience. A Heat Advisory remains in effect through 8 PM Tuesday. Be sure to stay hydrated, avoid strenuous outdoor activities, and never leave pets/people in vehicles! && .SHORT TERM... (Tuesday through Thursday) Issued at 819 AM CDT Mon Aug 18 2025 Lack of synoptic forcing will keep rain chances low (30% or less) through most of the short term period. If showers/storms develop, they will be during the peak afternoon heating hours and will be scattered in nature. Sufficient instability (sfc CAPE ~1000 J/kg) and low level lapse rates (~9 C/km) will allow threats with any storms to include frequent lightning as well as gusty winds up to 40-50 mph. Lack of wind shear should prevent any organized severe development of storms. Heat will continue to be a concern through at least Tuesday evening, during which our Heat Advisory remains in effect for high temperatures in the mid to upper 90s and heat indices up to 107 (primarily along and west of I-65). We drop below Heat Advisory criteria Wednesday, however, it will still be hot with highs in the 90s and heat indices up to 100-104 with isolated areas up to 106. If these temperatures trend higher in future forecast updates, the Heat Advisory may be extended. Be sure to stay hydrated, limit strenuous outdoor activities, wear light-colored clothing, and check on friends/family. Wednesday into Thursday, weak upper level troughing and a cold front stemming from the Great Lakes region is forecast to influence the area. There is a low chance this front evolves into an MCS, which would increase the risk for locally damaging winds and heavy rainfall. We have low confidence in exact timing of this at this moment due to some slight model disagreement. The timing of this will also affect temperatures Wednesday if it moves in earlier, and could result in cooler temperatures than forecast. One thing is for certain: a slight cool down is forecast afterwards as highs should decrease to the upper 80s to lower 90s with heat indices topping out around 95-100 degrees. && .LONG TERM... (Thursday night through Monday) Issued at 819 AM CDT Mon Aug 18 2025 An upper level trough continues to influence the area through the weekend, bringing increased cloud cover as well as low to medium rain chances daily. However, this will also result in decreased temperatures as highs peak in the 80s throughout most of the area. While we are still too far out to get into specific threats with any potential thunderstorm development, storms will likely be capable of producing heavy rainfall as PWATs are forecast to be around 1.7-1.9", which is around the 75th to 90th percentile per BMX sounding climatology. && .AVIATION... (18Z TAFS) Issued at 1219 PM CDT Mon Aug 18 2025 VFR conditions are forecast through the TAF period at both KMSL and KHSV. && .HUN WATCHES/WARNINGS/ADVISORIES...
