...DISCUSSION...
Medium-range guidance is in good agreement that the upper low
centered over IL early D4/Monday will remain progressive, moving
across the Lower/Mid OH Valley and Lower MI on D4/Monday and through
the Lower Great Lakes region on D5/Tuesday. Cold front associated
with this system is forecast to move eastward well ahead of the
upper low and attendant increased mid-level flow, with this
displacement limiting the severe weather potential. High surface
pressure and dry conditions in the wake of this front will keep
severe potential very low for the eastern CONUS after from
D6/Wednesday through D8/Friday. 

Thunderstorms are possible throughout the period across the western
CONUS amid persistent southwesterly flow aloft and sufficient
mid-level moisture. Modest buoyancy and lack of strong shear should
keep the severe potential low.
