Updated at 621 PM CDT Fri Aug 8 2025 - A warming trend will continue through the weekend with afternoon highs in the low to mid 90s. - Rain chances remain low (up to 30 percent) this weekend, but increase through next week. By Monday, daily precipitation chances will be 40 to 50 percent through the end of the week. && .DISCUSSION... (This afternoon through next Thursday) Issued at 1241 PM CDT Fri Aug 8 2025 Morning visible satellite reveals another quiet morning across the region with a few overnight showers having dissipated. In the meantime, high pressure continues to build as upper height rises occur behind the weak trough that has moved to our east over the last few days. As such, temperatures have already risen and highs are anticipated to be in the 90s area-wide starting this afternoon. With increasing temperatures, surface theta e will also begin rising as tropical moisture remains throughout the region allowing diurnal showers to return. Although CAMs aren`t very confident on rain this afternoon, morning upper air profiles from surrounding regions already show > 1000 J/kg of MUCAPE which will only grow through the day. Additionally, a weak remnant MCV is propagating south over the Mississippi River, which could be an additional focus point for deeper convection this afternoon. Regardless, a few showers or thunderstorms appear likely this afternoon across Tennessee and northeast Mississippi, diminishing in strength after sunset. Highs will stay in the 90s this weekend as ridging persists or even strengthens into next week. Although upper moisture has continued to be lacking, daily showers have managed to develop through the week. PoPs may be underdone for tomorrow afternoon but high forecast uncertainty precludes an increase in PoPs at this time. NBM guidance has been trending towards higher PoPs, bringing 30% to portions of northeast Mississippi, a significant uptrend from 24 hours ago. This trend is seen moving forward through the forecast as well with upwards of 50% across north Mississippi Monday and Tuesday. The primary driver of this increasing likelihood in precipitation is an increase in upper moisture as ridging builds to our east, allow for moisture advection from lower latitudes. Therefore, next week is looking wetter with daily showers and storms across the majority of the region starting Monday. As precipitation chances increase next week, temperatures are still forecast to stay in the mid 90s. Heat indices remain around 100 F through the period with isolated areas reaching 105 F. Some uncertainty still exists within the temperature forecast with higher rain chances, which could mute high temperatures in some areas. Therefore, heat headlines do not appear likely at this time across the Mid-South, but temperatures will still be seasonably warm and uncomfortable through the end of the period. && .AVIATION... (00Z TAFS) Issued at 635 PM CDT Fri Aug 8 2025 TSRA over northwest MS will continue to push south through mid- evening, eventually decreasing in coverage and intensity. Around MEM, the lower atmosphere has stabilized and should remain free of rain overnight. To the east, isolated but persistent TSRA north and east of TUP should gradually diminish through 02Z or so, as the lower atmosphere stabilizes. None of the short term guidance suggests fog overnight. But given recent heavy rainfall, clearing skies and calm winds, at least TEMPO for limited visibility appears warranted at MKL. Winds at MEM winds should remain sufficient to limit radiation fog concerns overnight. PWB && .FIRE WEATHER... Issued at 1241 PM CDT Fri Aug 8 2025 No fire weather concerns this period as light 20ft winds and MinRH values around 50 percent persist for at least the next 7 days. && .MEG WATCHES/WARNINGS/ADVISORIES...
