A storm system arriving from the southern Plains will bring additional showers and thunderstorms to Arkansas today and tonight.
Isolated to scattered severe storms could occur across the southern half to one-third of Arkansas today and tonight. The main concern will be large hail and damaging winds, however a tornado can not be ruled out. The environment will be most unstable (warm/moist) toward the Gulf Coast, and that is where damaging winds/a few tornadoes are most favorable.
The forecast calls for an additional one-quarter of an inch to over one inch of rain across the state today and tonight. Locally heavier amounts are possible in the south and southeast portions of the state. Any flash flooding should be localized.
Sub-freezing temperatures possible Sunday morning over portions of Arkansas.
