...There is an Enhanced risk of Severe Thunderstorms over the Lower
Mississippi Valley/Southern Plains on Friday...

...There is a Slight Risk of Excessive Rainfall over parts of the Southern
Plains and the Lower Mississippi/Tennessee Valleys on Friday...

...Critical fire weather conditions are expected to continue from the

Low pressure over the Southern Plains will move eastward to off the
Mid-Atlantic Coast by Sunday.  The system will produce severe
thunderstorms and heavy rain from the Southern Plains to the
Southeast/southern Mid-Atlantic.  The SPC has issued an enhanced risk of
severe thunderstorms over parts of the Lower Mississippi Valley/Southern
Plains on Friday into Saturday morning.  The main hazards with these
storms will be frequent lightning, severe thunderstorm wind gusts, hail,
and a few tornadoes.  There is an added risk of a 10% or greater
probability of two-inch or larger hail over parts of central Texas and
Oklahoma.  Additionally, the WPC has issued a slight risk of excessive
rainfall over parts of the Southern Plains and the Lower
Mississippi/Tennessee Valleys on Friday into Saturday.  The thunderstorms
will produce heavy rain with scattered flash flood areas possible.  The
most vulnerable places will be urban areas, roads, and small streams.

A second front over the Upper Midwest will move eastward to the Lower
Great Lakes by Sunday.  The system will produce rain over parts of the
Upper Mississippi Valley/Upper Great Lakes into parts of the Ohio Valley,
Mid-Atlantic, and the Northeast through Sunday.  The storm will also
produce light snow over parts of the Upper Mississippi Valley and the
Upper Great Lakes from Friday evening into Sunday morning.

Meanwhile, upper-level energy and troughing will produce light snow over
parts of the Northern Rockies/Northern High Plains into the Central
Rockies on Friday that will end by Friday evening.  Furthermore,
additional upper-level energy will move onshore over the Pacific Northwest
on Friday evening into Saturday.  The developing front will move from the
Northwest to the Northern High Plains/Northern Rockies to the Great Basin
and Southern California by Sunday.  The system will produce rain and
higher elevation light snow over parts of the Northwest/Northern
California to the Northern Rockies/Great Basin starting overnight Friday
into Sunday.  

The Southwest, Southern Rockies, and Southern High Plains will be dry. 
Gusty winds and low relative humidity have prompted the SPC to issue an
elevated/critical risk of fire weather from northern Arizona/southeast
Utah to the Southern High Plains, including much of New Mexico and western
Texas, on Friday.
