...There is a slight risk of severe thunderstorms over parts of the
Northern Plains...

...Temperatures will be 10 to 15 degrees below average over the Pacific
Northwest...

A front over the Northern Rockies to the Great Basin will move slowly
eastward to the Upper Mississippi Valley by Friday evening.  Moisture will
be pooling ahead of the boundary over the Northern Plains to the Upper
Mississippi Valley.  Areas of showers and thunderstorms will develop in
the moist air over the Central/Northern Plains that will move to the Great
Lakes by Friday evening.  In addition, showers and thunderstorms will
develop along the U. S./Canadian border from the Northern High Plains on
Wednesday to the Upper Mississippi Valley on Friday morning.  By Friday
evening, the showers and thunderstorms will expand southward along the
front to parts of the Middle Missouri Valley.  Additionally, upper-level
energy moving over the Pacific Northwest will produce light rain over
parts of the area through Thursday evening. 

A second front will move off the Northeast/Mid-Atlantic Coast on Thursday
while the southern end of the boundary will linger over parts of the
Central Gulf Coast and the Southeast Thursday afternoon into Friday
evening.  Showers and thunderstorms developing along the front will move
off the New England Coast on Thursday morning.  Additional showers and
thunderstorms will develop along the boundary over the Tennessee Valley
into the Mid-Atlantic on Thursday moving off the Mid-Atlantic Coast on
Friday morning.  Showers and thunderstorms will also develop over parts of
the Southeast on Friday evening. 

Elsewhere, upper-level energy over the Central Gulf Coast will trigger
showers and thunderstorms over parts of Texas and the Gulf Coast through
Friday.  Furthermore, moisture trapped underneath an upper-level ridge
over the Southwest/Southern Rockies will produce areas of showers and
thunderstorms over the area on Thursday and Friday.
