491 FXUS64 KMEG 142336 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 636 PM CDT Sat Sep 14 2024 ...New AVIATION... .SYNOPSIS... Issued at 233 PM CDT Sat Sep 14 2024 Scattered thunderstorms will remain in the forecast across the Mid-South through Monday. Some areas could see an additional 1 to 2 inches of rainfall between now and Monday evening. By Tuesday, drier and slightly warmer conditions are expected through the remainder of next week. && .DISCUSSION... (This evening through next Friday) Issued at 233 PM CDT Sat Sep 14 2024 Very little changes from the previous forecast as our soggy weather pattern will remain across the Mid-South through Monday thanks to the remnants of Francine. Surface low has drifted over north MS through the day, bringing additional showers across the region. Very little movement is expected from this low pressure over the next 48 hours, keeping a dreary weather pattern across the Mid-South. I have knocked the thunderstorm potential back a bit based on observations through the day. While there is some surface instability, showers have struggled to tap into this potential and there hasn`t been any lightning activity across the area today. I won`t rule out thunderstorms completely, but my confidence is very, very low for any organized thunderstorm activity through the remainder of today and into tomorrow. Flood Watch continues for portions of the Mid-South along the TN River, but this remains highly conditional. Heaviest rainfall has luckily stayed to the east of the area, but will keep things status quo in case a convective band sets up through the afternoon to evening. Total additional rainfall amounts will likely be around 1 to 2 inches across the area. Amounts closer to 2 inches are more likely across north MS, with the potential for <1 inch elsewhere. Weak upper-level ridge will begin to develop across the south-central plains on Tuesday, slowly shifting across the region by the end of the work week. This will bring a drier and somewhat warmer pattern back to the Mid-South, likely lasting into next weekend. High temperatures will generally remain in the 80s with overnight lows in the 60s, which is near normal for the area for mid-September. && .AVIATION... (00Z TAFS) Issued at 628 PM CDT Sat Sep 14 2024 An upper low will continue to churn over the Mid-South leading to a pretty decent IFR deck spreading across the airspace around midnight. By daybreak, conditions begin to improve to MVFR across much of the area. An improvement to VFR conditions finally looks to begin around sunset tomorrow. This same low will also bring intermediate periods of -SHRA/BR with reduced vsbys across all terminals. A very weak LLJ will extend from northern AL to West TN leading to LLWS at MKL later this evening. Northeast winds will remain elevated around 8-12 kts through the TAF period.
