Later this afternoon a weak cold front will progress east. The temperature swing will not be drastic, but the cooler more dry air will help initiate thunderstorms along the warmer humid air in southern Arkansas.
CAPE values (instability - fuel for thunderstorms) are not off the chart by any means, but there is enough to support some thunderstorm development. Notice the higher values across southern Arkansas near the Louisiana border.
The Storm Prediction Center in Norman, Oklahoma has placed a small sliver of southern Arkansas into a "Marginal Risk" area for this afternoon. We have created a graphic, and posted it above to help better paint the picture. The area highlighted in light green is the focus area for storm development this afternoon, remember this a relatively weak system and we are NOT expecting anything substantial. However, the risk is not zero, so it cannot be ignored.
