....DISCUSSION...
Overall upper pattern across the central and eastern CONUS is
expected to undergo significant amplification from D4/Saturday into
D7/Tuesday as a series of shortwave troughs move through
progressively deeper troughing. By early D7/Tuesday, upper troughing
is expected to extend from the primary cyclone over the Canadian
Maritimes into the central Plains.

A cold front is expected to accompany the first shortwave trough,
moving across the eastern CONUS on D4/Saturday and D5/Sunday.
Limited buoyancy should keep the thunderstorm potential along this
front low. Strong ridging will follow in the wake of this front,
with dry and stable conditions precluding thunderstorms across the
majority of the CONUS. The only exception is along the Gulf
Coast/Florida, where enough low-level moisture may be in place to
support some thunderstorms.
