...DISCUSSION...
Medium-range guidance indicates that there will be substantive
further amplification of large-scale mid-level troughing to the east
of the Mississippi Valley early next week.  Peak amplitude may occur
near/east of the Atlantic Seaboard early Wednesday, when cool
surface ridging may enco*pass much of the interior U.S. into areas
offshore of the Gulf and southern Atlantic coasts.

Although another vigorous digging short wave impulse may reinforce
the larger-scale mid-level troughing near the northern Atlantic
Seaboard into late week, a southerly return flow may develop across
the southern Great Plains toward the Upper Midwest, ahead of
significant mid-level troughing emerging from the mid-latitude
Pacific.  It is possible that this could be acco*panied by at least
some increase in thunderstorm development ahead of an associated
cold front Thursday through Friday.  However, it is not yet clear
that low-level moistening will contribute to sufficient
destabilization to support more than low probabilities for severe
thunderstorms.
