Isolated severe storms could occur over western Arkansas today. Large hail would be the main concern.
Isolated to scattered severe storms could occur across mainly the southern half of Arkansas on Friday. The main concerns will be large hail and damaging winds; however, a tornado or two can not be ruled out. The environment will be most unstable (warm/moist) toward the Gulf Coast, and that is where damaging winds and a few tornadoes are most favored.
The forecast calls for one to two inches of rain across much of the state, with locally heavier amounts possible in the north. Any flash flooding should be localized.
