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 May 31, 11:23 PM CST, 37 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 1223 AM CDT Tue Jun 1 2021 .DISCUSSION... Updated to include the 06Z aviation discussion below... && .AVIATION... Coverage of SHRA will increase overnight into Tue morning as an upper level system moves over the state. Expect conditions to decrease as a result...though will remain VFR for a while this morning until the heavier precip develops. Some TSRA may also be seen. No widespread improvements are expected until beyond this TAF period. && PREV DISCUSSION...(ISSUED 253 PM CDT Mon May 31 2021) SHORT TERM...Tonight Through Wednesday Deepening H500 trough will slowly progress eastward across the middle of the country in the coming days. Much of Arkansas will be on the eastern edge of the trough through the period and as numerous impulses round it base and lift north, widespread showers and thunderstorms will develop across the area. Accompanying these upper features will be a deep plume of moisture extending northeast across the state. PW values on the order of 1.75 to 2 inches will be focused over the area, aiding in the threat for locally heavy rainfall. There remains some variability in where CAM solutions show thunderstorms producing the heaviest rainfall, but portions of western and northern AR remain favored. While many areas likely won't see very heavy rainfall amounts, some locations could see totals exceed 2 or 3 inches in a fairly short timeframe given expected high rainfall rates. Temperatures through the period are expected to remain below average with widespread cloud cover and frequent chances for showers and thunderstorms. Southeast portions of the area are expected to be closest to average for early June but may still fall a few degrees shy. LONG TERM...Wednesday Night Through Sunday Behind the passage of a weak cold front on Wednesday, drier air and subsidence will work its way across Arkansas, leading to what may be 48 hours or so of relatively dry weather in an otherwise rainy weather pattern. Behind the front and shortwave trough, low-level moisture will be pushed just south of the state while subsidence helps to clear skies out aloft. However because of rainfall on Tuesday and Wednesday, and generally healthy vegetation and high soil moisture conditions, Wednesday's front will only bring dew point value down about 10 degrees across the state. High soil moisture and healthy vegetation will promote rapid shallow moisture recovery which is expected to interact with the peak heating hours of the day each day resulting in pop-up/hit and miss showers and thunderstorms. These afternoon thunderstorms are likely Thursday and Friday until deeper moisture returns to the region for the weekend ahead. By Saturday, the medium to long range model guidance indicates that a low pressure system over Baja Mexico will move northeast towards the southern plains this weekend out ahead of deep Gulf moisture return. The return of deeper moisture and weak forcing for ascent will allow for a greater coverage of showers and thunderstorms each afternoon this upcoming weekend headed into early next week. Somewhat weak flow aloft and deep moisture will make heavy rainfall the primary threat from storms this weekend headed into early next week. It's too early to determine if we will need additional flash flood watches for the weekend at this time, but that will be the primary hazard to evaluate in later forecasts. && .LZK Watches/Warnings/Advisories...

Heavy rainfall will become a concern by sunrise. .DAYS TWO THROUGH SEVEN...Tuesday Through Sunday A storm system will slowly move through Arkansas through mid-week, with several rounds of showers and thunderstorms expected. As the system moves slowly through the region, storms will form and move repeatedly over the same areas. With heavy rainfall expected and already saturated soils from previous heavy rainfall, flooding will become a concern, with the highest likelihood over northern and western Arkansas. The heavy rainfall threat will decrease later in the week as the slow-moving storm system departs. .Spotter Information Statement... Spotter activation is not anticipated at this time. && Visit NWS Little Rock on the web. Go to http://weather.gov/lzk. 67
