406 FXUS64 KMEG 152329 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 529 PM CST Sat Nov 15 2025 ...New AVIATION... .KEY MESSAGES... Issued at 528 PM CST Sat Nov 15 2025 - Above-normal temperatures and dry conditions will persist through the weekend. - Wet and unsettled weather, including periods of showers and thunderstorms, will return next week. At least 1 to 2 inches of rainfall is expected with low confidence on amounts over 3 inches. && .DISCUSSION... (This afternoon through next Friday) Issued at 1125 AM CST Sat Nov 15 2025 Surface high pressure and zonal flow aloft persist to maintain our dry and above-normal temperature pattern. An approaching cold front is tightening the pressure gradient allowing for breezy conditions across the region. Winds will be breezy and gusty through the day and ease after sunset. The moisture pull ahead of the cold front is to be expected, but given the dominance of high pressure over the past several days, the passage is expected to remain rain-free. The aforementioned cold front is not expected to complete its path across the Mid-South until Sunday evening. A pattern change will kick off the work week on Monday as a deepening longwave trough over the central U.S. begins to take on a negative tilt. A leading shortwave ahead of the deeper trough, will move across the Central Plains. Ahead of the shortwave, enough moisture pull will support isolated shower and thunderstorm development on Monday. There is still uncertainty on the shortwave track resulting in model disagreement on location, coverage, and timing of showers and storms. A few showers may emerge as early as Monday morning, but most likely timing will be the afternoon and evening. The model spread of precipitation coverage is also affecting temperature forecast due to cloud coverage and rain cooled surfaces. We are just getting into the range of hi-res guidance so Monday should become more clear by the next forecast issuance. The front that crossed the area on Sunday, is anticipated to retreat north on Tuesday resulting in WAA showers and thunderstorms. This warm front is expected to stall over the Mid- South keeping showers and thunderstorms in the forecast once again on Wednesday. Due to the type of front, conditions will remain warm and humid on Tuesday and Wednesday. Despite several days of rain chances, QPF amounts through early Thursday morning are around 1" with slightly higher totals to the north and slightly lesser to the south. Thursday is when the deepening longwave trough will finally eject from the Plains. Pre-frontal showers and thunderstorms are expected ahead of the main trough. From previous model runs, the speed of the trough appears to be slower and not actually crossing the region until Friday. Severe weather potential remains uncertain due to timing and model disagreement, but heavy rainfall is also a concern. NBM QPF amounts have increased significantly and are forecasting 2-4" with locally higher amounts up to 5" from Wednesday morning to Saturday evening. The LREF is not favorable of this outcome as probabilities of >3" through Saturday evening are 25% or less. The long term forecast remains of many possibilities, but it will be an active end to the week. DNM && .AVIATION... (00Z TAFS) Issued at 528 PM CST Sat Nov 15 2025 VFR conds expected through the period. SW winds around 10 kts will shift to NW as a cold front moves through later tonight. LLWS will redevelop this evening in advance of the cold front. Winds tomorrow will be northeasterly generally 8-10 kts. && .FIRE WEATHER... Issued at 1125 AM CST Sat Nov 15 2025 Minimum RH values (50-60%) will remain elevated as return flow continues to bring in moisture. Gusty winds and dry soils could lead to a minimal grass fire threat, but the elevated RH values are sufficient to keep the overall concern low. A wet and unsettled pattern begins on Monday, bringing daily chances for showers and thunderstorms with wetting rain. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None.
