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 Apr 25, 5:03 PM CST, 1 hour 12 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 603 PM CDT Mon Apr 25 2022 .UPDATE... Updated to include the 00Z aviation discussion. && .AVIATION... VFR conditions are expected over all sites throughout the forecast period. Cigs will continue to raise becoming clear over the course of the forecast period. Winds will be predominately out of the N and NW early in the period across all terminals, then becoming predominately out of the NE by 26/12Z for all sites. && .PREV DISCUSSION...(ISSUED 240 PM CDT Mon Apr 25 2022) Short Term...Tonight thru Wednesday... Cold front has pretty much pushed thru the forecast area late this afternoon, and some lingering precipitation will persist in the southeastern zones for a short while this evening. The upper level trof over the region will continue to push eastward overnight, and a weak ridge will start to build in tomorrow. The lagging trof will allow a considerable amount of high level clouds to loiter over the area tonight. Cooler and drier air is filtering into the region, and this should allow for fairly mild afternoon temperatures tomorrow and Wednesdays, with highs in the upper 60s to the lower 70's in most areas. Extended Term...Wednesday Night thru Monday Night... S/Erly sfc flow returns to the region as the Srn periphery of high pressure begins to lift N/Ewrd out of the MS/OH River Valley. Daily temps and sfc moisture content should begin to moderate and trend upward w/ near-normal to slightly above-normal condns returning to most locations through the end of the week. Global guidance remains consistent regarding the approach of a shortwave perturbation on Thurs over the Cntrl Pacific Coast. Overall trends cont to suggest the feature wl quickly translate E/wrd, pivoting towards a more negative stance as it traverses over the Cont Divide, resulting in a high amplitude but relative short wavelength upper ridge over the Midwest. Good agreement is also noted on the magnitude and location of the associated sfc mass response, positioning a broad but deepening sfc low over Cntrl High Plains near Wrn KS/OK-TX panhandle vcty. Chc PoPs return to the FA by Fri, particularly Nrn AR, where WAA/isentropic ascent wl be greatest, w/ coverage expanding Swrd and Ewrd through the weekend as upper-lvl forcing swings by the N/Wrn portion of the state. Upper-lvl progs suggest the upper trof may lose some potency as it pivots and quickly becomes semi-cutoff, becoming more of a closed-low than progressive wave feature...in- turn weakening the sfc low as well and yielding a cold frnt that wl lkly make it into N/Wrn AR and wash out across the state sometime Sat or Sun, resulting in sporadic and scattered Chc PoPs/storms through the weekend and into the new work week. Given the trends on the far longterm, wl reiterate this bit from the morning fcst package since it sums up the potential outcome pretty well...Be warned, this has the makings of the classic "Spring frontal boundary approaches Arkansas, Spring frontal boundary meets upper ridge and stalls, waves move through and interact with the aforementioned boundary, interaction of the systems equals periods of showers and thunderstorms, some with heavy rainfall" story. (Same old soap opera, different episode). && .LZK Watches/Warnings/Advisories...NONE. && Aviation...234

Rain will be heavy at times, especially over the northwest third of the state. The heavy rainfall could cause localized flash flooding into the morning hours. However, rainfall will decrease in coverage and intensity by mid day and into the afternoon. Also, the risk of any strong storms is low through tonight. Due to excessive rainfall in the last 12 to 24 hours, flooding is expected to become a concern along the Petit Jean and Fourche Lafave Rivers, though at this time, the high stages do not appear to be prolonged. .DAYS TWO THROUGH SEVEN...Tuesday Through Sunday While dry weather will prevail by mid-week, it does appear that Arkansas will be headed back into a wet and stormy pattern by the end of the week and into next weekend. Locally heavy rainfall could become a concern again. Also, high river stages will remain a concern through the period, primarily along the Ouachita, Lower White, Black, and Cache Rivers. Through Sunday, the risk of strong storms is low. .Spotter Information Statement... Spotter activation is not anticipated at this time. && Visit NWS Little Rock on the web.
