Scattered storms (a few supercells) produced strong and gusty winds over north Alabama during the late morning hours ahead of/along a trough axis ahead of a frontal boundary north of the area. Isolated tree damage was reported in the Tuscumbia area with a small weakly bowing line of storms.

Area Forecast Discussion National Weather Service Huntsville AL 926 AM CDT Tue Jul 23 2024 ...New NEAR TERM... .NEAR TERM... (Rest of Today) Issued at 926 AM CDT Tue Jul 23 2024 A stationary boundary lingering across central Tennessee has allowed continued showers/storms and overcast to broken cloud cover to remain over much of the Tennessee Valley. Rain chances are forecast to increase throughout the day, peaking during the afternoon hours when they reach high chances (70-90%). Our primary concern throughout the day will be flooding as training of storms is forecast (storms moving over the same area repeatedly) along with high PWATs. PWATs are forecast to be around 2-2.1", exceeding the 90th percentile sounding climatology per BMX and allowing storms to be efficient rainfall producers. Sufficient low level lapse rates and CAPE values will support frequent lightning and strong updrafts this afternoon, especially south of the Tennessee River. Weak mid level wind shear should keep convection unorganized and the tornado threat low. Therefore, primary threats outside of flooding today will be gusty to damaging winds and frequent lightning. We will be monitoring how these morning showers affect instability this afternoon. Otherwise, highs are forecast to reach the low 80s with heat indices in the upper 80s to low 90s. && .SHORT TERM... (Tonight through Thursday night) Issued at 225 AM CDT Tue Jul 23 2024 An unsettled weather pattern will continue into Thursday. The moisture rich airmass, passing upper level support and daytime heating will bring more high rain chances on Tuesday. With more moisture and clouds, Wednesday and Thursday appear will be the "cooler" days with highs actually closer to 80/lower 80s. Have continued a trend of the highest PoPs in the afternoon for both days, with rain chances lower in the night. CAPE profiles more skinny on Wed and Thu should support general thunderstorms, and a potential for locally heavy rainfall. Rain coverage on Wed looks to more widespread but not as heavy as on Tue. A similar view on Thu with the heaviest rain displaced to the east. Despite on-going drought (which is being chipped away by locally heavy rainfall), instances for ponding of water in low area, and/or flash flooding cannot be ruled out. && .LONG TERM... (Friday through Monday) Issued at 225 AM CDT Tue Jul 23 2024 The 5h pattern will make a gradual transition during this period as heights builds over the Gulf of Mexico and into the Gulf States. The amplitude and longitudinal position of this ridge and the influence on the troughs over the east Coast and the evolution the wave that will be lifting north or northeast out of TX and LA. On Friday, the convergence zone/frontal boundary will still be in place, so the greatest chances of during the period will be on this day. Then, a more typical summertime situation will occur with low chance diurnal thunderstorm activity each day despite the ridge. Temperatures will also be going up each day, with lower to perhaps middle 90s for afternoon highs Sat-Mon. && .AVIATION... (12Z TAFS) Issued at 646 AM CDT Tue Jul 23 2024 Inclement weather is forecast across the TN Valley into the late night, as a very moist atmosphere remains in place. Passing upper level disturbances and increased instability from daytime heating, will result in widespread showers/thunderstorms especially this afternoon. Have increased higher rain chances to include the KHSV terminal this issuance. With the precip being showers, have kept VCTS into the evening under prevailing VFR conditions, with TEMPO or PROB30 for periods of lower CIG/VSBY from heavier rain and/or storms. The better rain chances should end in this evening. Given that wetting rainfall is likely to occur, have added fog to the latter portion of the TAF. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
