...DISCUSSION...
An upper trough will move from the MS Valley toward the OH Valley
and Great Lakes on Wed/D4, with a secondary trough moving across the
Four Corners and into the Southern Plains. An occluded surface low
will also move across the upper Great Lakes, with a cold front
moving across the OH/TN Valleys and toward the Appalachians. While
low-level moisture will support rain and thunderstorms along this
front, the lifting of the upper system and weak instability will
result in decreasing severe risk. This weakening trend should
continue into Thu/D5 as the front moves across the Mid Atlantic and
off the East Coast. Behind these systems, the pattern will favor
high pressure and minimal chances of thunderstorms.
