...Synopsis/Discussion...
Morning water-vapor imagery depicts a midlevel shortwave trough
tracking eastward from eastern MT into the Dakotas. This feature
will continue eastward across the northern Plains/Canadian Prairies
into the overnight/early morning hours. In the 04-12Z time frame,
associated cooling aloft atop a cool/stable boundary layer will
contribute to weak elevated instability across the Upper Midwest.
Given strong low-level warm advection and midlevel ascent preceding
the trough, isolated thunderstorms are possible.

Farther south, a separate low-level jet will promote a band of
showers over the Upper TX Coast during the overnight hours. Related
low-level warming/moistening will contribute to weak instability,
though dry air aloft should generally limit lightning potential.
