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 21, 1:41 AM CST, 39 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 241 AM CDT Tue Apr 21 2020 .SHORT TERM...Today Through Wednesday Night Coverage of fog early this morning is much more limited compared to Mon morning due to more SFC flow and less low level moisture in place. Even so...cannot rule out any patchy fog through this morning. However...coverage should be limited enough to not need any Dense Fog Adv at this time. SFC cold front will push south through the area this morning into the early afternoon hrs...with additional dry air filtering into the state. As a result...the forecast should remain dry through this afternoon and early evening. By tonight...SFC low pressure will develop west of AR as a new upper level shortwave exits the SRN Rockies into the OK/TX Panhandles by early Wed morning. Chances for SHRA/TSRA will increase late tonight into early Wed morning over WRN/NWRN sections of the area as a disturbance moves over NWRN AR downstream of the upper shortwave. The overall threat for SVR Wx late tonight into Wed morning should be limited...with maybe some marginally SVR hail across the NWRN sections of the CWA. The upper shortwave and SFC low will move closer to the state during the daylight hrs on Wed...with scattered convection possible throughout the day into the afternoon hrs. There remains some differences on timing...and overall position of SFC features in the latest near-term guidance. Some solutions keep the warm front from lifting north across SRN/Central AR until late Wed afternoon or even into the evening hrs. This scenario will keep most convection elevated in nature into much of the afternoon or even early evening hrs...and the more SFC based convection holding off until later in the evening hrs. However...other solutions do lift the warm front further north and sooner in time. As a result...uncertainty does remain on the overall evolution of the SVR Wx threat for Wed into Wed night. For now...the best chances for seeing organized SVR Wx look to be across the SWRN/SRN third/half of the CWA late Wed afternoon...or primarily Wed evening into the overnight period. Given this timing...overall instability may be lacking some...but will have to see how this situation evolves. Even so...there will be some threat for damaging winds and large hail...with a tornado or two remaining possible as well. The hail threat could extend further north with non-SFC based storms...with the damaging wind and tornado threat staying further south. Locally heavy rainfall will also be seen...which could lead to an isolated flash flood threat. The SVR Wx threat will then decrease as the storm system exits the region early in the long term period. && .LONG TERM...Thursday Through Monday The extended period forecast will remain unsettled as a couple of storm systems move through the region. Thursday morning will start off rainy, as an upper level low and frontal boundary push eastward through the Natural State. Rain should diminish through the day, but the break in precipitation will be short lived as another shortwave trough and cold front approach the Mississippi Valley Region from the west. Rain should linger through the early portion of the coming weekend, but drier weather will return for the end of the period. Temperatures should be fairly pleasant Thursday through Monday with highs generally in the 70s and lower 80s. However, on Saturday after the aforementioned cold front moves through, temperatures will be quite a bit colder with highs only reaching the mid 60s and lower 70s. Lows will be in the 40s and 50s through the period. && .PRELIMINARY POINT TEMPS/POPS...
