...There is a Slight Risk of severe thunderstorms over parts of the
Central Plains and an Enhanced Risk of severe thunderstorms over parts of
the Lower Mississippi Valley on Saturday...

...Snow over the Northern/Central Rockies and light snow over parts of the
Upper Mississippi Valley on Saturday...

...Temperatures will be 15 to 25 degrees above average over parts of the
Upper Mississippi Valley, Great Lakes, and Northeast...

An area of low pressure extending from the Upper Mississippi Valley to the
Central Plains will slowly move eastward to the Upper Great Lakes/Middle
Mississippi Valley by Sunday. On Friday, showers and severe thunderstorms
will develop along the associated front over parts of Kansas and Nebraska.
Therefore, the SPC has issued a Slight Risk of severe thunderstorms over
parts of the Central Plains through Saturday morning. The hazards
associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a minimal threat of tornadoes. In
addition, there will be a threat of severe thunderstorm wind gusts of 65
knots or greater and hail of two inches or greater diameter over parts of
the Central Plains.

On Saturday, the threat of severe thunderstorms increases slightly as the
front moves eastward into the Lower Mississippi Valley. Therefore, the SPC
has issued an Enhanced Risk of severe thunderstorms over the Lower
Mississippi Valley from Saturday into Sunday morning.

The hazards associated with these thunderstorms are frequent lightning,
severe thunderstorm wind gusts, hail, and a few tornadoes. Moreover, there
is an increased threat of hail two inches in diameter or greater over the
Lower Mississippi Valley.

On the storm s west side, snow will develop over parts of the
Northern/Central Rockies on Friday, while an area of light snow will
develop over parts of the Upper Mississippi Valley on Saturday.

Meanwhile, an upper-level low over the Southeast on Friday will create
showers and thunderstorms over the region that will slowly move northward
into parts of the Mid-Atlantic and Ohio Valley by Friday evening. On
Saturday, the upper-level low weakens slightly as showers and
thunderstorms extend from the Ohio Valley to parts of the Northeast.

Additionally, on Friday, north of the upper-level low, upper-level ridging
will allow temperatures to become 15 to 25 degrees above average over
parts of the Upper Mississippi Valley, Great Lakes, and Northeast.

Elsewhere, a front will move onshore over the Pacific Northwest on
Saturday and dissipate, while another front moves onshore on Sunday. The
systems will produce coastal rain and highest elevation snow over the
Northern Cascades late Saturday morning into Sunday.
