It was not a huge rain event on February 20th and 21st, but parts of Arkansas did pick up appreciable liquid. A storm system gathered strength in the southern Plains, and pulled moisture northward from the Gulf of Mexico.

 

The satellite showed a swath of moisture and heavy rain from the Gulf of Mexico into the southeast United States at 600 pm CST on 02/21/2017. This was ahead (east) of a storm system ("L") in Mississippi. Behind the system, scattered light rain lingered in Arkansas.

The bulk of the rain fell before dawn on the 21st. As the storm system exited to the east, scattered mainly light rain followed, especially over central and southern sections of the state.
