...There is a slight risk of severe thunderstorms over parts of
the Northern Plains/Upper Mississippi Valley and the Central
Plains...

...Heavy rain possible over parts of the Southeast...

A weakening front over parts of the Southeast to the Lower
Mississippi Valley and upper-level energy will aid in producing
showers and thunderstorms over parts of the Southeast/Southern
Mid-Atlantic westward to Middle/Lower Mississippi Valley through
Friday evening.  In addition, upper-level energy over the Northern
High Plains into the Central Rockies will slowly move eastward to
the Upper Great Lakes/Western Ohio Valley by Friday night. The
energy will aid in producing showers and thunderstorms over parts
of the Northern High Plains into the Upper Mississippi Valley and
southward to the Southern High Plains that will move slowly
eastward into the Upper Great Lakes to the Middle Mississippi
Valley by Friday evening.  There will be a diurnal component to
the areal coverage with these thunderstorms.  Elsewhere, a front
near Northern Maine will aid in producing showers and
thunderstorms over parts of Northern New England on Friday
afternoon into Friday evening. 

Meanwhile, a developing upper-level low off the California Coast
will slowly move inland over California into parts of the Great
Basin Friday evening into Saturday.  The energy will aid in
producing coastal rain and inland showers/thunderstorms over parts
of Northern/Central California by Thursday evening.  The coastal
rain and inland showers/thunderstorms will expand into parts of
the Pacific Northwest and the Great Basin overnight Thursday
continuing into Friday evening/Saturday.  Before the upper-level
low develops, weak upper-level energy over parts of the Pacific
Northwest will aid in producing showers and thunderstorms over
parts of the Pacific Northwest and the Northern Intermountain
Region through late Thursday night.
