My previous post, I opened my mouth too soon about today's rain potential. Sometimes as meteorologists we rely too much on computer model forecast data. Now having looked at the radar, I see that indeed rain is heading our way. (The models could be a few hours too slow moving the rain in.)
Here is the radar image from 1:35pm CT. There is some rain trying to move north/northeast out of Arkansas in to southeast Missouri.
Keep in mind, the initial rain activity will be light showers.
