...DISCUSSION...
Expansive upper ridging is expected to be in place across much of
western North America on D4/Wednesday, with this ridging expected to
persist through the weekend. Upper troughing will likely extend from
northern Quebec through Ontario, the Upper Great Lakes, and the Mid
MS Valley early D4/Wednesday. Primary portion of this upper trough
is forecast to gradually shift eastward across the remainder of
Ontario and the Upper Great Lakes on D4/Wednesday and the Northeast
on D5/Thursday, but modest upper troughing is expected to remain in
place over much of the eastern CONUS into the weekend.

At the same time, a cold front will gradually push
southward/southeastward across the central Plains, OH Valley, and
Northeast on D4/Wednesday and northern part of the southern Plains,
Mid-South, and TN Valley on D5/Thursday. Some limited severe
potential may exist across the Northeast on D4/Wednesday before the
front clears the region. After D4/Wednesday, progression of the
front will displace the better low-level moisture south of the
stronger flow aloft, limiting the severe-storm potential across much
of the central and eastern CONUS through the weekend. The only
exception is across the High Plains, where modest low-level moisture
beneath vertically veering wind profiles could support a few strong
to severe storms each afternoon.
