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 Feb 28, 11:40 PM CST, 20 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 1140 PM CST Wed Feb 28 2018 .AVIATION... Widespread RA with embedded +RA remains across central AR with bouncy flight categories, both for vsby and cig. This trend will continue through the overnight with +RA at LLQ by 01/08Z. Widespread MVFR will continue with IFR and worse in rain bands through 01/10-12Z. Some degradation of cigs possible at northern terminals around and after 01/12Z, but remained optimistic in TAFs. Gusty N winds expected through the day Thurs. with gradual improvement N to S during the late AM into the PM. Confidence in timing and restrictions remains low. Cooper && PREV DISCUSSION...(ISSUED 244 PM CST Wed Feb 28 2018) DISCUSSION... Main concerns in this forecast cycle remain the potential for heavy rain in the next 24 hours and the potential for flooding or flash flooding over areas that are already saturated or rivers in flood or close to flood stage. Also a slight and marginal risk of severe storms this evening to early overnight as the weather system and cold front move through AR. This afternoon the area of light to moderate convection has continued to move east across, earlier over the northern half, while this afternoon more central and southern AR. Most rain amounts have been light to moderate, with so far less than an inch. The rain was in response to a warm front lifting across AR, which was not located near the AR and MO stateline, and some upper level short wave energy moving through the mean upper southwest to northeast flow. Models do gradually move the main lift from the north to central and southern areas later today, tonight and into Thursday until the cold front pushes through AR and clears the rain east. Precip water values have come up to well over an inch, and the heavy rain threat remains over AR, and a moderate to high risk of rainfall exceeding flash flood guidance with this system. Also, the slight to marginal risk of strong to severe storms is forecast to be focused over the southern half of AR, when the strongest lift moves across AR this evening to early night, and the best instability. Winds and hail are the primary threats, while a low tornado threat will be seen. Temperatures had warmed to the lower 70s south, while 60s elsewhere. SHORT TERM...Tonight Through Friday The forecast will start with a high chance of rain and thunderstorms, with the threat of heavy rain. Will not include some severe storms possible due to low threat. The heaviest rain threat is forecast to center over central to southern AR this evening and tonight, as the the upper lift is focused over central to southern AR, and the cold front also gradually moves through the state. 2 to 4 inches of rain is forecast in the next 24 hours, with isolated areas seeing up to 5 inches over eastern to southeastern areas. This will lead to continued flooding on area rivers and in those areas that are already flooding. Lows tonight will mostly be in the 50s. Thursday will see the system move out of AR, taking the rain out of the state. A west to northwest wind flow will usher in drier and a bit cooler air into the state. Highs on Thursday will be in the 50s to 60s. Surface high pressure will then build in over the region, and bring dry weather conditions on Friday. LONG TERM...Friday Night Through Wednesday An upper ridge will be over the Plains to begin the long term period with upper low pressure systems over the Pacific Northwest and New England. The High will slowly move east through the weekend and reach the east coast Monday. An upper low moves into the Plains Sunday and into the Midwest Monday. Northwest flow sets up over Arkansas for Tuesday and Wednesday. Dry conditions with high pressure are expected for Friday night through Saturday night. Rain chances return to the west Sunday and spread eastward with an upper level system. A cold front will move through on Monday and the showers should end in the southeast Monday morning. Monday night through Wednesday will be dry with high pressure in place and a northwest flow over the area. Near normal temperatures will continue through the period. && .LZK Watches/Warnings/Advisories...

Rain will be heaviest over central and southern Arkansas where another two to more than four inches of rain could fall. This additional rainfall will only aid in the worsening flood conditions already in place from the most recent heavy rainfall event across the area. There will also be the possibility of isolated severe storms, with hail and winds the main threats. An isolated tornado may also develop. The main threat area will be over the southern half of Arkansas late this afternoon and evening. .DAYS TWO THROUGH SEVEN...Thursday Through Tuesday Rain will end during the day Thursday. Dry weather is forecast the rest of Thursday, Friday and Saturday. The chances of rain will be back in the forecast Sunday with the next weather system to affect the region. Due to the recent prolonged period of heavy rainfall, river stages are expected to remain high into next week. Flooding will continue in several river basins, including the Black, White, Cache, Ouachita, and Saline Rivers. .Spotter Information Statement... Spotter activation may be necessary late this afternoon and this evening, given the possibility of severe weather. && Visit NWS Little Rock on the web. Go to http://weather.gov/lzk.
