506 FXUS64 KMEG 310543 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 1143 PM CST Thu Jan 30 2025 ...New AVIATION... .UPDATE... Issued at 903 PM CST Thu Jan 30 2025 A potent upper level low is pushing toward the Mid-South tonight. An axis of widespread showers and embedded thunderstorms cover much of north MS and West TN with precip starting to taper off west of the MS River. This axis will shift east overnight and exit the region by mid-morning. The heaviest rain overnight into the early morning is expected across north MS where an inch is expected with locally higher amounts. Fortunately, the axis of heavier precip is moving out of the area that had 3-4 inches of rain earlier today and into an area that has not seen a lot of rain so far. As a result, the flooding threat will diminish. The flooding threat is winding down north of I-40 with the Flood Watch scheduled to expire at midnight. The severe threat continues to look very marginal. There is plenty of shear but surface based instability is non-existent. The main threat is gusty winds but those should stay sub-severe. && .SYNOPSIS... Issued at 230 PM CST Thu Jan 30 2025 Heavy rain will continue to impact the Mid-South through Friday morning, resulting in flooding concerns north of I-40. A brief severe weather threat may materialize this evening, but overall confidence is low. As for the rest of the forecast: expect above average temperatures with rain chances returning by the middle of next week. && .DISCUSSION... (This evening through next Wednesday) Issued at 230 PM CST Thu Jan 30 2025 Training showers continue to impact areas north of I-40 this afternoon. Rainfall estimates as of 230 PM remain between 2 and 4 inches with several areas reporting road closures as local rivers and streams rise above bankfull. The latest guidance suggests continual rainfall in this area through midnight. Additional flooding is likely until cessation of heavy rains. In addition, a low confidence severe weather threat may materialize this evening in areas of north Mississippi. Increased confidence is hindered by a lack of cloud breakage, limiting available instability. However, the 18Z HRRR continues to develop a line of storms as the front swings through the area tonight. Overall, the severe weather window will last for a few hours, from 5-8pm. The greatest threat will be damaging winds. A pleasant pattern will emerge this weekend as zonal flow aloft dominates. Expect warming temperatures on Sunday, leading to above average temperatures next week. Guidance continues to struggle with a frontal passage, or two, next week. However, a few things are clear: 1 - above average temperatures will persist, 2 - rain chances increase by midweek. ANS && .AVIATION... (06Z TAFS) Issued at 1140 PM CST Thu Jan 30 2025 Tonight`s showers and thunderstorms have moved out of MEM/JBR and will continue over MKL/TUP over the next several hours.
