931 FXUS64 KHUN 272230 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 530 PM CDT Mon May 27 2024 ...New AVIATION... .NEAR TERM... (Tonight) Issued at 124 PM CDT Mon May 27 2024 Tranquil weather across the Tennessee Valley this afternoon is in stark contrast to the very stormy weather we experienced in the predawn hours earlier this morning. In wake of the cold front that brought us those storms, a dry air mass is filtering into the region which has resulted in a pleasant Memorial Day with partly cloudy conditions and temperatures in the low to mid 80s. Cloud cover will quickly diminish with the loss of heating later this evening. The clear/calm conditions (along with the moist boundary layer from earlier rainfall) will create an environment favorable for patchy fog late tonight into early Tuesday morning. && .SHORT TERM... (Tuesday through Thursday) Issued at 124 PM CDT Mon May 27 2024 High pressure at the surface will build into the region Tuesday through Thursday, promoting mostly sunny and dry conditions each day. However, we will remain under the influence of a broad upper- trough over the Great Lakes which will keep our mean flow out of the northwest -- reinforcing a slightly cooler and drier air mass. As a result, highs will run slight below normal for the end of May, especially Wednesday and Thursday when they will peak into the upper 70s to lower 80s. && .LONG TERM... (Thursday night through Sunday) Issued at 1055 PM CDT Sun May 26 2024 Dry air continues through the end of the week as upper level ridging moves into the Tennessee Valley from the west. On Friday evening, an upper level shortwave allows low-medium rain chances to return to the area and continue through the weekend. During the long term period, highs are forecast to be in the upper 70s/80s with overnight lows in the 50s/60s. && .AVIATION... (00Z TAFS) Issued at 530 PM CDT Mon May 27 2024 VFR conditions with light northwesterly winds are expected through the TAF period. There is a low chance of some fog near sunrise at both terminals, but confidence is low in this occurring so therefore put that reduction in visibility in a TEMPO group. && .HUN WATCHES/WARNINGS/ADVISORIES...
