NWS Huntsville, AL wrote its last area forecast discussion before the first event at Aug 7, 10:28 AM CST, 39 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 1128 AM CDT Sun Aug 7 2022 ...New AVIATION... .NEAR TERM... (Rest of Today) Issued at 941 AM CDT Sun Aug 7 2022 An upper low is indicated in water vapor imagery and 4-2h streamflow analysis centered over western TN. The low is shifting west as a ridge pushes westward from the east-southeast CONUS. Convection will likely develop once again today. Favored locations may be in northwest AL into middle TN closer to the upper low, but outflow boundaries and the Cumberland Plateau may also serve as a focus as well. Similar to yesterday, locally intense downpours, brief gusty downburst winds and possibly some hail are expected. No significant changes to the forecast are being made, with scattered thunderstorms possible. Initial development varies in CAMs, varying from late morning to early afternoon, but would probably favor earlier development given the solar heating already underway with a limited cloud field this morning. && .SHORT TERM... (Tonight through Wednesday) Issued at 239 AM CDT Sun Aug 7 2022 Will remain in a fairly typical summertime pattern through the middle of the week as an upper ridge becomes well amplified over the western CONUS and a trough begins moving into eastern Canada. High pressure off the southern Atlantic coast will keep southerly flow over the southeast, and daily chances for showers and storms will persist. A sfc front will be the focus for convection to our north during this timeframe, while our convection will be more diurnally driven coupled with a few weaker disturbances aloft. This front will slowly push south toward the mid-week timeframe, and coverage is expected to increase Tuesday and Wednesday as the front nears the Tennessee Valley. Afternoon SBCAPE values will near 2000 J/kg each day but shear looks minimal until Wednesday, when the upper trough and front dig into the area. PWATs near 2" and weak flow will create at least some risk for flooding, so will have to monitor for stagnant/training storms. Some storms could be strong in nature, but severe weather is not expected. High temps will drop by a degree or two each day due to the increase in cloud cover and storm coverage. Expect highs in the upper 80s to lower 90s on Monday, falling to the mid to upper 80s by Wednesday. Overnight lows in the low to mid 70s are expected. && .LONG TERM... (Wednesday night through Saturday) Issued at 239 AM CDT Sun Aug 7 2022 Shower and storm chances will persist until the front is pushed through the area Thursday afternoon and evening, then slightly drier air will move across the area. Much of the area will stay dry on Friday, but the forecast for the weekend seems a lot more uncertain given model discrepancies at this range. Stuck with blended guidance for the long term, keeping a drier forecast in through the first half of the weekend. Afternoon temps will reach the upper 80s to lower 90s with overnight lows in the upper 60s/lower 70s. && .AVIATION... (18Z TAFS) Issued at 1127 AM CDT Sun Aug 7 2022 Scattered TSRA are expected through around 23-00Z before diminishing and dissipated this evening. Frequent lightning, brief gusty winds, small hail and lowered visibility in +RA (LIFR OR IFR possible) will occur with the TS. Patchy BR/FG is possible late tonight after 06Z, but have not included at the TAF sites due to uncertainty. VFR weather is expected otherwise. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
