311 FXUS64 KMEG 202327 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 527 PM CST Thu Nov 20 2025 ...New AVIATION... .KEY MESSAGES... Issued at 520 PM CST Thu Nov 20 2025 - Wet and unsettled weather returns on Thursday and will persist through the end of the work week. - The upcoming weekend will be mostly dry with highs in the 60s and 70s. - Another unsettled pattern emerges next week with showers and thunderstorms possible through Tuesday. && .DISCUSSION... (This afternoon through next Wednesday) Issued at 1210 PM CST Thu Nov 20 2025 Showers and thunderstorms continue to form along a retreating warm front this morning, resulting in a gloomy day for the Mid- South. Rain chances will persist through the remainder of today with about an inch of rain falling in areas north of the I- 40 corridor. Precipitation will continue into Friday as a large upper level trough ejects out of the Desert Southwest. An additional half inch of rain is forecast through tomorrow evening, bringing the two day rainfall total to around 1.5 inches for portions of the Mid-South. Fortunately, conditions will dry out on Saturday as a cold front swings through the region. The remainder of the weekend will be mostly dry and cooler with highs in the 60s and 70s through Sunday. Elsewhere in CONUS on Saturday, another large upper level trough will develop over the Desert Southwest. A leading shortwave will eject towards the Mid-South on Monday, allowing dewpoints to climb to the 50s and 60s. Showers and thunderstorms will develop by midday, though continual cloud cover will limit destabilization. Thunderstorms will linger into Tuesday morning, but given the weakening trend of the upper trough and its northerly track, severe chances will be minimal (<10%). Depending on how models resolve this system as we move closer to the event, severe storms chances may change. Thanksgiving temperatures will be slightly below normal as an upper level low over the northern United States / Canada border ejects a strong cold front to the Mid-South on Tuesday. Eventual FROPA is anticipated early Wednesday with much cooler and drier air filtering into the region. Dewpoints will drop to the 30s areawide by the evening hours, setting the stage for efficient radiational cooling. Freezing temperatures will start the Thanksgiving Holiday. Continual CAA will temper highs on Thursday with the majority of the area remaining in the 50s. ANS && .AVIATION... (00Z TAFS) Issued at 520 PM CST Thu Nov 20 2025 Difficult TAF set remains this issuance. IFR and intermittent LIFR conditions will prevail for the overnight period across the airspace as a front lingers. Conditions should improve to MVFR around 15Z as the pressure gradient tightens and south/southwest winds gust up to 20 kts. -SHRA and BR will also impact terminals through much of the overnight period. -SHRA and BR are expected to return Friday evening, on the backside of the aforementioned front, but confidence remains low on the exact timing of said showers at this time. AEH && .FIRE WEATHER... Issued at 1210 PM CST Thu Nov 20 2025 Wetting rain chances persist through Friday, limiting the overall fire weather threat. MinRH values will remain above 50% through the remainder of the period with additional rain chances returning next week. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None.
