...Slight Risk (level 2/5) of severe thunderstorms over parts of
the Central Plains on Thursday...

...Slight Risk (level 2/5) of severe thunderstorms over parts of
the Central Plains/Middle Mississippi Valley on Friday...

...Mixed precipitation for the Pacific Northwest and Northern
Intermountain Region through Saturday...


Across central U.S. a frontal boundary stretching from northern
Plains/Upper Midwest into southern Plains will be the focus for
scattered showers and thunderstorms tonight into Friday. With
sufficient instability, chances for severe thunder storms will be
likely. Therefore, Storm Prediction Center (SPC) has issued a
Slight Risk (level 2/5) of severe thunderstorms across parts of
the central Plains and Southern High Plains. Additional hazards
associated with the storm will be hail and severe wind gusts. The
front will become semi-stationary across the Plains/Mississippi
Valley from Friday into Saturday, continuing chances for showers
and thunderstorms through the weekend. In addition, SPC has issued
a Slight Risk (level 2/5) for severe thunderstorms across portions
of the lower Missouri River Valley for Friday into Saturday. The
severe thunderstorm threat will expand Saturday into Sunday across
parts of the central Plains into lower to mid Missouri Valley as
the stationary frontal system that stretches across the Great
Basin into mid-Mississippi Valley, Ohio Valley, and Great Lakes
brings additional showers and thunderstorms along the boundary.

The surface low over Northeast will continue to move offshore, but
a shortwave trough will bring some scattered showers with a chance
for some isolated thunderstorms through early Friday morning. The
lingering front and shortwave energy near Florida will produce
some occasional showers and thunderstorms into Sunday. Over into
the west, a weak cold front will move into the Pacific Northwest
and a shortwave trough will bring some occasional low elevation
rain, and high elevation snow/mixed precipitation through Sunday.

Temperatures continue to trend above normal across much of central
U.S., into the weekend. As the upper-level ridge slowly moves
eastward, moderate temperatures over eastern U.S. will trend above
average into Sunday. Across the west, below normal temperature
return as the shortwave trough moves into the area.
