075 FXUS64 KMEG 131112 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 512 AM CST Thu Nov 13 2025 ...New AVIATION... .KEY MESSAGES... Issued at 511 AM CST Thu Nov 13 2025 - A significant warming trend will persist through Saturday. Temperatures will be well above normal with rain-free conditions. Gusty south winds are expected Saturday. - High uncertainty exists regarding the timing and strength of the next weather system, resulting in low confidence for rain chances and temperatures next week. && .DISCUSSION... (Tonight through next Wednesday) Issued at 1103 PM CST Wed Nov 12 2025 The latest surface analysis places a broad area of high pressure over much of the Mississippi Valley. Winds have already gone calm across 90% of the forecast area, with many locations already seeing dewpoint depressions of 3F or less. Given that many locations are expected to fall to or below the crossover temperature (the highest dewpoint from Wednesday afternoon), a medium to high signal exists for dense fog. There is quite a bit of uncertainty still as to how widespread the fog will be, however, it will likely be dense. After close collaboration with surrounding offices, decided to forgo a dense fog advisory at this time. Trends will need to be monitored. The upper level pattern will continue to feature an amplifying ridge in the western CONUS with a deepening trough off the eastern seaboard. The Mid-South will remain in dry northwest flow through late week. This will allow temperatures to climb about 10 degrees above normal for this time of year with highs in the low to mid 70s and lows in the 50s. A strong shortwave will move across southern Canada this weekend and spawn a 988mb surface low over the Great Lakes Region. This will tighten the pressure gradient across the entire Mississippi Valley and the Mid-South. NBM probabilities for winds greater than 20 mph are pinging in the 60-90% range across northeast Arkansas, the Missouri Bootheel, and northwest Tennessee. However, probabilities for 25 mph or greater, or wind advisory criteria, remain in the 10-20% range. Gusty southerly winds are expected, and trends will be monitored for any shift in advisory potential. A weak cold front will push through the Mid-South early Sunday, but will not generate any precipitation as PWATs will be below 1 inch. Slightly cooler temperatures are expected behind the front, but still above average with highs in the upper 60s and lower 70s. Synoptic models have come into better agreement with the evolution of a shortwave ejecting into the Plains on Monday. A surface low will develop across the Central Plains and lift a warm front through the Mid-South on Tuesday. This will set the stage for an unsettled pattern across the region through late next week. Confidence is low to medium regarding the exact timing and placement of frontal passages. However, a clear signal exists for the return of warm and wet weather to the Mid-South through late next week. && .AVIATION... (12Z TAFS) Issued at 511 AM CST Thu Nov 13 2025 VFR conditions continue. Winds will generally remain southeasterly up to around 5 kts, with a subtle shift to southerly near the end of the current TAF period. && .FIRE WEATHER... Issued at 1103 PM CST Wed Nov 12 2025 Temperatures will be well above normal through Saturday, with minimum relative humidity values likely remaining above 35 percent. Transport winds and mixing heights will generally be low to moderate. However, southerly flow will increase through Friday and become strong on Saturday. Overall burning conditions will remain good to moderate. The potential for wetting rains returns next week. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None.
