A series of reinforcing upper shortwave troughs will maintain mean troughing over the eastern U.S. during the Day 4-8 period. Upper ridging across the western states will persist on Day 4/Fri before an upper trough moves inland along the Pacific coast. This system will shift east toward the southern High Plains on Day 6/Sun while merging with the mean upper trough across the east late in the forecast period. Prior cold frontal passages deep into the Gulf of Mexico, and surface high pressure over the Plains, will preclude thunderstorm activity across most of the CONUS. However, by the end of the period, some modest moisture return may impinge on the western/central Gulf coast as the ejecting upper shortwave trough over the southern High Plains merges with the eastern trough over the Lower MS Valley/Southeast. However, quality moisture return appears unlikely, and severe thunderstorm potential will remain low.
