The showers and thunderstorms will move into parts of the Mid-Atlantic to the Southern Appalachians by Monday morning, dissipating by Monday afternoon.

In addition, upper-level energy over the Southeast to the Central Gulf Coast will move northeastward off the Mid-Atlantic Coast by Monday morning. The energy will aid in developing showers and thunderstorms from the Central Gulf Coast to the Southeast/Southern Mid-Atlantic Coast that will move off the Southeast/Southern Mid-Atlantic Coast by Monday afternoon, while showers and thunderstorms will linger over parts of Florida through Monday evening. A complicated front over the Northwest/Northern California will move eastward to the Central Rockies/Great Basin and the Southwest by Tuesday. The system will produce rain and higher elevation snow over parts of the Pacific Northwest on Sunday morning that will expand inland to the Northern High Plains/Central Rockies and into parts of Northern/Central California and the Great Basin on Sunday evening into Monday. The dynamic system will squeeze as much precipitation out of the atmosphere possible. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
