...DISCUSSION...
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.
