Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE SOUTHEAST INTO THE SOUTHERN AND CENTRAL APPALACHIANS SUMMARY Thunderstorms with isolated severe wind gusts will be possible this afternoon from parts of the Southeast into the southern and central Appalachians. Southeast/Southern and Central Appalachians A cold front will advance southeastward across the southern and eastern U.S. today. By afternoon, the front is forecast to be positioned from northern Mississippi northeastward to western Virginia. Ahead of the front, a moist airmass will be in place with surface dewpoints in the upper 60s to mid 70s F from the lower Mississippi Valley northeastward into West Virginia. As surface temperature warm, an axis of moderate instability will develop ahead of the front from central Mississippi northeastward into western North Carolina, where MLCAPE should peak in the 2000 to 3000 J/kg range. Low-level convergence will increase along the front during the day, which will be favorable for scattered to numerous thunderstorm development. Although deep-layer shear will be weak along and near the instability axis, low-level lapse rates will become steep in the afternoon. The thermodynamic environment should be favorable for isolated severe wind gusts with single cells or disorganized multicells. The threat should be largely diurnal but may persist into the early evening in areas that destabilize the most.
