No significant - Uncertainty still exists regarding a low-pressure system next Tuesday that could bring heavy rain and a mixed precipitation regime to the region. && .DISCUSSION... (This evening through next Friday) Issued at 1214 PM CST Sat Nov 29 2025 A mix of rain and sleet was observed across a large portion of the Mid-South this morning, mainly due to precipitation onset coinciding with below freezing temperatures. Given frigid temperatures aloft, a few areas may continue to experience light sleet over the next few hours before precipitation turns to a cold rain areawide. No sleet accumulation is anticipated. Rain chances will slowly dissipate tonight as a cold front moves through the area. Dry conditions resume by midday Sunday with afternoon highs ranging from the upper 30s to upper 40s. Another complex forecast emerges on Monday as a Gulf low tracks over southern Mississippi and Alabama. Ample moisture will funnel into the Mid-South by mid-morning with precipitable water values reaching the 90th percentile. Precipitation chances will increase at this time. One thing to watch out for is a brief period of mixed precipitation as surface temperatures are forecast to remain below freezing through about 10AM. Forecast soundings depict a stout warm nose spanning from 700 - 950 mb, so anything that does fall will melt before reaching the surface. This regime will favor a rain / ice pellet mix with ice pellets melting as they reach the ground. No significant impacts are anticipated Monday morning. As temperatures warm above freezing, a changeover to all rain is anticipated by midday. A different story will materialize Monday night into Tuesday as temperatures once again fall below freezing. Ample moisture will remain at this time, keeping our precipitation chances elevated. A changeover from rain to a wintry mix is anticipated shortly after sunset, with areas spanning from Jonesboro, AR northeast to Paris, TN seeing the greatest potential for wintry conditions. The latest forecast soundings keep the aforementioned warm nose through the overnight hours. As such, the potential for snow is on the decline (<15%). While a few flakes cannot be ruled out, sleet will be the likely precipitation mode. Given the potential for rain and sleet mixing, any accumulations will be minimal (less than an inch). A Winter Weather Advisory may be needed in future forecast updates for areas along the TN/KY border. Overall, don`t expect a white-out come Tuesday morning. Instead, keep an eye out for icy overpasses. Precipitation chances will dissipate Tuesday morning. Below normal temperatures will persist on Wednesday and Thursday with highs generally in the 40s and 50s. Another round of precipitation is anticipated for the end of the work week as a long wave trough moves across the Central Plains. Some guidance is depicting yet another wintry mix occurring for areas near the TN/KY border early Friday. However, large model spread and run-to- run inconsistencies keep confidence in any winter precipitation low (<15%). Stay tuned. ANS && .AVIATION... (18Z TAFS) Issued at 1214 PM CST Sat Nov 29 2025 There have been a few reports of PL upon the onset of precipitation across the Mid-South this morning.
