Heavy rain brought flooding to central Arkansas May 12, 2017.
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 12, 7:03 PM CST, 1 hour 27 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 803 PM CDT Fri May 12 2017 .AVIATION... For the 00Z TAFs... Scattered showers and isolated thunderstorms are expected to continue through 03Z across portions of central and southern Arkansas. MVFR to lower VFR cigs are expected across central and southern Arkansas through midnight. Drier air aloft is expected to filter in behind the upper low and cause clouds to scatter out overnight. Just before sunrise...mostly clear skies are expected across the state while light northerly winds will continue to bring drier air across the state. Light winds and clear skies may allow for some fog development across northern and central Arkansas early Saturday morning. Only went with a mention of MVFR visibility restrictions at this time as forecast soundings advertise a fairly steep hydrolapse immediately above the nocturnal inversion. This should promote enough dry air entrainment to prevent dense fog development tomorrow morning. After any morning fog clears out...VFR conditions are expected for the remainder of the day on Saturday with mostly sunny skies in place. Light northerly winds will likely veer around towards the east by sunset. Cavanaugh && .PREV DISCUSSION...(ISSUED 255 PM CDT Fri May 12 2017 ) SHORT TERM...Tonight through Sunday Upper low was centered ovr SWRN AR this aftn. Combo of aftn heating and colder air aloft was creating an unstable environment for a good amount of convection. The steep lapse rates have allowed for some small hail to accompany some of the storms. Wl also see locally heavy rainfall due to the slow movement of the activity. The upr low is fcst to cont working sloly EWD acrs SRN AR early tngt, eventually shifting away fm the state by Sat. Rainfall coverage wl gradually diminish in areal coverage and intensity this evening. Clouds wl decrease overnight as drier air/high pres blds into the region fm the NW. Included some patchy fog late tngt for parts of NWRN AR. High pres wl bring much drier and pleasant conds to the Natural State for the remainder of the weekend. Temps wl begin to moderate by Sun as south winds return and high pressure aloft blds into the region. Long Term...Sunday Night through Friday A ridge of high pressure will slowly shift from the middle of the country to the southeast United States. The high will then park for awhile, and will hold a storm system and front in the Plains. The first half of the period will be dry and warm. Above average temperatures are in the forecast. While the system to the west will have a hard time getting here, ripples of energy will eject from the system toward the mid-Mississippi Valley. This may trigger isolated to scattered showers and thunderstorms by Wednesday, especially in the northwest half of Arkansas. The incoming storm system is rather large, and there will be plenty of moisture available when it eventually gets here. Given this, we may be looking at a heavy rain event as the period ends or just after the period. The timing is in question due to the aforementioned ridge. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...CAVANAUGH
