A dry, continental airmass across the eastern CONUS and northern Gulf will keep severe weather potential low on D4/Fri and D5/Sat. By D6/Sun, as the mid-level low starts to translate into the southern Plains, robust low-level moisture advection is expected to occur ahead of a developing surface cyclone. After this time, severe weather may be possible any day through early next week. In general, the overall pattern suggests moisture returning to the southern Plains and

A strong mid-level trough will amplify across the East Coast on Thursday with a strong cold front sharpening along the Appalachians and moving into the Atlantic. Given the persistent continental airmass preceding the cold front with minimal moisture recovery, instablity should be quite weak. However, forecast soundings show some weak instability which could promote a few lightning flashes across the Carolinas and vicinity. In the wake of the cold front, dry air will remain across
