The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Little Rock, AR wrote its last area forecast discussion before the first event at Sep 11, 5:05 PM CST, 25 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 605 PM CDT Sat Sep 11 2021 .AVIATION... Updated for 00Z terminals... VFR conditions are expected through the period. Winds will be variable at around six knots or less. Expect a continued layer of haze/smoke aloft, but this is not expected to affect flight operations. && .PREV DISCUSSION...(ISSUED 245 PM CDT Sat Sep 11 2021) SHORT TERM...Tonight Through Monday Another day of benign wx noted acrs the Natural State this aftn as the region rmns under the influence of a sfc ridge. Meanwhile, an upper high was centered to our W. The resulting NW flow aloft conts to bring a good bit of smoke fm the Wrn wildfires acrs the region. The resulting hazy skies have actually helped to keep aftn temps a few degrees lower than originally fcst. As we close out the weekend and start a new work week, the pattern acrs the region wl bcm a it more unsettled. The aforementioned sfc rdg is fcst to weaken, which wl allow a gradual incrs in moisture/ clouds fm the Gulf region. The focus wl be on a tropical disturbance that is progged to sloly strengthen in the coming days as it works along the coast of Mexico. In a nutshell, Sun looks to be another dry day with high temps close to todays readings, ranging fm the mid 80s to the lower 90s. Clouds wl start to incrs fm the S later Sun ngt and contg on Mon. Kept low chc PoPs in the fcst Mon, mainly acrs cntrl/srn AR where moisture lvls wl be a bit higher. Trended high temps a bit lower Mon aftn, esp acrs S AR, due to the additional cloud cover. LONG TERM...Monday Night Through Saturday Long term guidance continues to depict a zonal upper air pattern across the northern half of the U.S. with weakening upper level ridging across the south by the beginning of the long term period. Continuing to see the zonal pattern amplify with a deepening upper SWT across the Midwest towards midweek. Southerly flow will return moisture to the region through the period as well. A cold front will approach the state from the NW Wed, bringing some rain chances to our northern counties, but the front does not appear to move into the area. The main source of moisture and energy will be the tropical disturbance moving up from the south. This disturbance is currently located over southeast Mexico and is forecast to track north across the western GoM, entering the LA/MS/AR region by midweek. Will continue to watch over the next few days to see how this system evolves. If it does continue this track, expect rainfall potential to increase mid to late next week across the state, with greatest potential for southern AR. Near average high temperatures and slightly above average low temperatures are forecast next week. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...57
