Issued at 646 PM CDT Fri Oct 2 2026 - Isolated light showers and periods of drizzle will occur tonight, behind a cold front that passed through the region Friday afternoon. - The cold front may lift back north into northeast Mississippi on Saturday, with temperatures warming back into the 80s. The remainder of the Midsouth will see highs in the 70s on Saturday. A few showers will be possible Saturday, mainly south of I-40. - Fair and mild weather will prevail Monday and Tuesday, with highs ranging from the mid 70s to lower 80s. Tuesday morning will likely see the coolest temperatures, with lows ranging from the upper 40s over parts of West Tennessee and the Missouri bootheel, to the lower 50s elsewhere. && .DISCUSSION... (This evening through next Thursday) Issued at 1224 PM CDT Fri Oct 2 2026 Morning observations depict an expansive area of precipitation over much of the Mid-South, particularly over eastern Arkansas, the Missouri Bootheel, and West Tennessee. Along and west of the Mississippi River, precipitation takes on more of a stratiform appearance with forcing from the right entrance region of a 500 - 200 mb jet streak and subtle low-level convergence due to an advancing front. To the east of the Mississippi, convection is currently the predominant mode of precipitation as MUCAPE values surge to between 500 - 1000 J/kg. Morning upper air data from LZK shows a very moist atmosphere containing 2.3"+ PWATs. Therefore, shallow convection will be capable of heavy rainfall and localized flooding east of the Mississippi with light stratiform precipitation elsewhere through tonight. Due to the large amount of cloud cover and widespread precipitation, highs are expected to remain in the 70s and 80s except for portions of northern Mississippi where cloud cover will be minimal, leading to highs in the low 90s. A similar forecast is in the cards for tomorrow as the front continues to slowly sag south through Tonight. However, the majority of the upper dynamics that will aid Friday`s precipitation will have left the region, leading to a lower coverage of precipitation from the stratiform regime, which by this point will exist over all but northern Mississippi. Northern Mississippi on the other hand will still be able to generate MUCAPE values of at least 1000 J/kg, kicking off another round of thunderstorms through Saturday evening. Again, expect high temperatures to remain close to the same as Friday in both space and magnitude. Additional showers are possible Sunday over northern Mississippi as a disturbance develops within the Gulf and pushes more moisture inland. Again, expect heavy downpours to be the primary impact from any precipitation. Into Monday, the front will have made its way into central Mississippi, erasing mentionable PoPs along with it. In its wake, cooler and drier weather will filter into the region with afternoon highs Monday and Tuesday in the middle to upper 70s. Furthermore, lows are forecast to drop into the 50s and even into the upper 40s across portions of West Tennessee starting Monday. Similar forecasts are expected through Wednesday with a gradual warming trend through the end of the week as post-frontal advection wanes. && .AVIATION... (00Z TAFS) Issued at 635 PM CDT Fri Oct 2 2026 A surface cold front cleared TUP earlier this afternoon, leaving all Midsouth TAF sites with N/NE surface winds around 10KT. Through the evening and overnight, a steady stream of midlevel clouds bearing -SHRA and boundary layer cooling will increase relative humidity in the post-frontal airmass, with IFR CIGs a good bet. Conditions should improve to MVFR toward 18Z at Midsouth TAF sites. Confidence in VFR for Saturday afternoon is limited at this time, given persistent NE surface flow and expected strength of the low level thermal inversion. && .FIRE WEATHER... Issued at 1224 PM CDT Fri Oct 2 2026 Widespread wetting rains and southerly moisture transport will keep fuels humid and minimum relative humidity values above 40% through this weekend. A front currently bisects the region from southwest to northeast, which will continue to push south over the next few days. South of the front, expect light, southerly 20- foot winds with a northerly wind shift north of the boundary. Drier conditions will take hold by Monday with relative humidity values beginning to drop back below 40%, but wetting rains should keep fuels humid enough to limit fire danger concerns. && .MEG WATCHES/WARNINGS/ADVISORIES...
