....DISCUSSION...
A southern-stream shortwave trough is forecast to progress across CA
and into the Great Basin on D4/Tuesday, continuing eastward through
the Four Corners region on D5/Wednesday and central/southern Plains
on D6/Thursday. A shortwave trough is expected to progress through
the northern stream during this period as well, moving from eastern
MT/southern Saskatchewan across the Upper Great Lakes into southern
Quebec and the St. Lawrence Valley. The northern stream is expected
to remain active, with another shortwave may follow in the wake of
the first, moving over the Canadian Prairie Provinces on
D5/Wednesday and into the Upper Great Lakes/Ontario vicinty on
D6/Thursday. Another, more substantial wave may approach the west
coast late in the period.

Surface cyclogenesis is expected over the central High Plains ahead
of the southern stream wave on D4/Tuesday, with the resulting low
progressing across KS/OK on D4/Tuesday, through the Mid MS Valley on
D5/Wednesday, and across the northern Mid-Atlantic on D6/Thursday.
Dewpoints in the upper 50s/low 60s will precede this front, but
mid-level temperatures will remain relatively warm on D4/Tuesday and
D5/Wednesday, limiting thunderstorm chances. Cooler mid-level
temperatures may eventually spread over the frontal zone on
D6/Thursday, increasing thunderstorm chances. However, overall
buoyancy will still be limited, tempering the severe potential.
