A severe thunderstorm warning has been issued for several Arkansas Counties.

Crittenden County, Cross County, Mississippi County, Craighead County, and Poinsett County are under the warning until 9:45 a.m.

The main threats associated with this storm are 60 mph wind gusts and penny-sized hail.

At this point, the Storm Prediction Center has placed our area under a SLIGHT risk for severe weather, which means some scattered severe thunderstorms will be possible. This does include Shelby County.

TIMING: A round of showers and thunderstorms moved through during the morning hours. However, the severe weather threat is not expected until late afternoon and early evening when the front finally moves through the area. The timing for this strong line of thunderstorms will be 3 p.m. to 7 p.m. Rain will start in eastern Arkansas around 3 p.m. and then move into far west Tennessee around 4 p.m. Rain will be exiting our far eastern counties in Tennessee and northeast Mississippi around 7 p.m. 

EXPERT ANALYSIS: This cold front isn't particularly strong, but it could provide enough lift to produce one or two strong thunderstorms. Our humidity will also be high, which will provide an additional ingredient for thunderstorm development. Our available energy (CAPE) for thunderstorms to form is expected to be on the high side and we have a few other signs that point to the threat for hail. Not all storms will produce hail, but this will be the greatest threat with strong storms that pop-up in the afternoon and evening. 

Another major factor will be whether or not there is clearing of clouds between the system in the morning and the system in the late afternoon. If we get some sunshine and are allowed to heat back up, thunderstorms will be more likely. However, if the clouds hang around all afternoon, our thunderstorm potential will be much lower.

THREATS: Heavy rain, lightning and thunder will be the main components in these thunderstorms. However, some scattered thunderstorms could produce hail. Strong wind gusts will also be a concern with some storms.
