Heavy rain brought flash flooding to parts of Arkansas on February the 28th. By the 28th, thermometers were in the mid to upper 70s across the central and southern counties. It was 76 degrees at Little Rock (Pulaski County) and Monticello (Drew County). It certainly felt like spring, and thunderstorms were back in the forecast.
Storms were sparked by a new cold front that penetrated into northwest Arkansas by lunchtime on the 28th, and approached the Louisiana border toward evening. Along the way, downpours were widespread, and there was at least a concern for severe weather (damaging winds, large hail, and maybe a tornado or two).
In the end, this was mainly a heavy rain event. Roads were flooded in Malvern (Hot Spring County), Pine Bluff (Jefferson County), and Sheridan (Grant County). Severe storms were few, with trees blown down at Greenbrier (Faulkner County) and Olmstead (Pulaski County), and nickel size hail just west of Wooster (Faulkner County).
