Area Forecast Discussion National Weather Service Huntsville AL 224 PM CDT Fri Apr 9 2021 .NEAR TERM...(This Evening and Tonight) Issued at 224 PM CDT Fri Apr 9 2021 Very busy afternoon and evening expected with multiple rounds of strong to severe thunderstorms expected. As of 19z this afternoon, initial clusters of convection have formed along a differential heating boundary roughly located along a line from Sylacauga to Cullman to Russellville. Latest mesoscale analysis indicates a more favorable environment for storms, with some steep low-level lapse rates and SBCAPE values approaching 3000 J/kg along and southwest of this boundary. Precipitable water values behind this feature also increase markedly to as high as 1.2" to 1.4" This feature will continue to move northeast into the area over the next 2-3 hours. The combination of this favorable instability and lift from the boundary will generate scattered to numerous clusters of storms, mainly capable of damaging winds and large hail. Due to the slow movement of these cells, localized flash flooding will also be a concern. Additional rounds of strong to severe storms are expected late this evening and overnight as a southern stream shortwave over Texas lifts NE into the Mid-South and interacts with a deepening cut-off low racing SE from the central Plains. Global models and CAMs differ slightly on timing, but all indicate the potential for a couple of MCS/QLCS features developing and moving into the Tennessee Valley region during this overnight hours. The first MCS will likely be tied to the aforementioned shortwave lifting northward from Texas and the lower Mississippi Valley, with a timeframe of 9 PM to 2 AM from west to east. A second and potentially stronger MCS will begin to take shape late this evening over the southern Plains and Ozarks and quickly move ESE/SE across the Mississippi Valley and across much of the Deep South and portions of the Tennessee Valley. The timing of this line of storms will be very late tonight into Saturday morning (3 AM to 10 AM Saturday morning). Given the stronger shear profile associated with the upper-low, this second line will also likely be severe with damaging winds, potentially over 70 mph, large hail, and a few tornadoes will be possible. With multiple rounds of heavy rainfall, most areas will see at least 2" of rainfall, with some areas seeing higher amounts. Due to mostly saturated soils, flash flooding will be possible. .SHORT TERM...(Saturday through Sunday) Issued at 224 PM CDT Fri Apr 9 2021 CAMs continue to indicate the main severe threat will be waning by the early to mid-morning hours on Saturday as the best shear and instability combination gets squeezed to our south with the passing of the second MCS. Lingering shower activity will persist into the afternoon, before tapering off as dry air filters in from the west. High pressure will build into the region Saturday night into Sunday, resulting in a sunny day and dry weather to close out the weekend. .LONG TERM...(Sunday night through Thursday) Issued at 224 PM CDT Fri Apr 9 2021 High pressure will remain the dominant weather feature across the area early next week, with mostly sunny and warm conditions expected and highs near the 80 degree mark. Another weak shortwave with skirt the Deep South Wednesday into Thursday, bringing the potential for some scattered showers and storms. Models differ somewhat on timing so have stuck close to NBM for now. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1211 PM CDT Fri Apr 9 2021 VFR conditions will continue through much of the afternoon and evening hours, before ceilings lower substantially to MVFR to IFR levels late this evening and overnight. Numerous showers and storms are expected to develop along and ahead of a cold front, with reduced visibilities and gusty winds likely. Amendments will likely be needed during this timeframe. The TSRA threat will diminish late in the period as the front pushes east, but lingering SHRA can be expected through the remainder of the period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
