Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 402 AM EDT Sat Apr 25 2015 Valid 12Z Sat Apr 25 2015 - 12Z Mon Apr 27 2015 ...There is a slight risk of severe weather for parts of the Southern Ohio Valley/Tennessee Valley/Southeast... ...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. Ziegenfelder Graphics available at
