...There is a slight risk of severe weather for parts of the Southern Ohio
...Temperatures will be 10 to 15 degrees below average over parts of the
Middle Missouri Valley/Ohio Valley and the Mid-Atlantic/Northeast...
A wave of low pressure over the Middle Mississippi Valley will move
eastward off the Mid-Atlantic Coast by Sunday evening. The system will
produce rain over parts of the Middle Missouri/Mississippi Valleys into
the Ohio Valley that will move eastward into the Mid-Atlantic by Saturday
evening and departing the Mid-Atlantic Coast by Sunday evening. Showers
and thunderstorms will develop over parts of the Ohio Valley/Southeast and
the Middle/Lower Mississippi Valley/Western Gulf Coast becoming limited to
parts of the Southeast by Sunday evening.
Meanwhile, upper-level energy over the Pacific Northwest will move
southeastward to the Southern Rockies while forming a closed low by
Sunday. The broad energy will aid in producing coastal and lower
elevation rain and higher elevation snow over parts of the Pacific
Northwest to Northern/Central California and parts of the Great Basin
through late Saturday night. Snow and lower elevation rain will also
develop over parts of the Northern/Central Rockies and the Southwest/Great
Basin through Sunday evening. Rain will develop over the Northern High
Plains and expand into Central High Plains Saturday evening into Sunday.
As the energy moves to the Southern Rockies, showers and thunderstorms
will develop over parts of the Southern Plains by Sunday evening. In
addition, an approaching Pacific front will return rain to parts of the
Pacific Northwest Coast by Sunday evening.
