230 FXUS64 KMEG 150800 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 300 AM CDT Sun Sep 15 2024 ...New SYNOPSIS, DISCUSSION... .SYNOPSIS... Issued at 300 AM CDT Sun Sep 15 2024 Showers and perhaps a few thunderstorms will continue across the area today. Dry conditions will finally return to northwest Tennessee late tonight and area wide by Tuesday morning. Sunny skies and dry weather will persist through early next week with normal temperatures expected. && .DISCUSSION... (Today through Saturday) Issued at 300 AM CDT Sun Sep 15 2024 Rainy conditions will continue today across the Mid-South as a remnant low, that was once Tropical System Francine, churns over north Mississippi. Most prominent at 925 mb, but extending to 700mb, a moisture field moving from southeast to northwest keeps rain bands training across the area. As the low slowly sinks south, the aforementioned moisture field will sink south as well allowing the rain bands to soak drought stricken north Mississippi. There is very low probabilities for thunder (~40% or less) with the shower activity today. Thunderstorms would be most likely across north Mississippi, particularly the Delta region. Thunder chances would increase if there are any cloud breaks allowing surface based instability to increase with daytime heating. With these bands, QPF for areas south of I-40 is 0.5-1.5". Areas to the north of I-40 will see an inch or less through tomorrow morning with the highest amounts being in northeast Arkansas. Impacts from the remnant low will finally end for northwest Tennessee near midnight tonight. The entire Mid-South should finally dry out by Monday evening. Monday night into Tuesday morning, fog development is possible particularly over northwest Tennessee under clearing skies, light winds, and a saturated surface. On Tuesday, the sun will shine with near climatological temperatures (in the mid to upper 80s) for September to return as high pressure builds. As a synoptic blocking pattern sets up, this pattern will continue through next weekend. DNM && .AVIATION... (06Z TAFS) Issued at 1130 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 JBR/MEM/TUP over the next few hours. MKL may lower to IFR, though confidence was not high enough to include in TAF. 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 at JBR/MKL/TUP. This same low will also bring intermediate periods of -SHRA/BR with reduced vsbys across all terminals. Northeast winds will remain elevated around 7-12 kts through the TAF period. AEH && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None.
