...DISCUSSION...
An upper trough/low should meander slowly eastward from the Upper
Midwest across the Great Lakes/OH Valley this upco*ing weekend,
eventually reaching the East Coast around the middle of next week.
While a low chance for isolated/marginally severe storms may develop
each afternoon across parts of the eastern states, modest mid-level
winds and related deep-layer shear associated with this upper trough
should generally limit the overall threat for organized severe
thunderstorms through the extended forecast period. Otherwise, an
upper ridge over the western states should continue to erode as
multiple upper troughs/lows move eastward across this region.
Regardless, severe chances should remain low across the western
states owing to a lack of sufficient forecast instability for robust
convection.
