Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 405 PM EDT Sat Apr 19 2014 Valid 00Z Sun Apr 20 2014 - 00Z Tue Apr 22 2014 ...Heavy rain to move off the Southeast Coast... ...Temperatures will be 10 to 15 degrees above average over the Northern Plains... A front over the Upper Midwest will become stagnate only moving to the Upper Great Lakes by Monday, while a second front over the Northern Rockies will move eastward to the Upper Mississippi Valley/Central Plains by Monday. Rain will develop along the boundary over the Upper Midwest moving into the Upper Great Lakes by Monday. Showers and thunderstorms will develop also along the front over parts of the Central Plains/Central Rockies on Saturday evening. The showers and thunderstorms will move into the Southern Plains by Sunday morning and move eastward to parts of the Middle/Lower Mississippi Valley on Sunday evening into Monday. The front over the Northern Rockies will be mainly dry over the region with a little snow over the area on Saturday evening. The boundary will intersect moisture flowing northward over the Plains on Sunday afternoon producing light rain over parts of the Northern Plains on Sunday evening moving into parts of the Upper Great Lakes by Monday. Meanwhile, onshore flow will aid in producing rain and highest elevation snow over parts of the Pacific Northwest through Sunday afternoon. In addition, another front will approach the Pacific Northwest Coast by Monday morning accompanied by light rain along the coast. Elsewhere, upper-level energy over the Southern Rockies will produce showers and thunderstorms on Saturday afternoon and evening ending by early Sunday morning. Furthermore, low pressure along the Southeast Coast will move slowly northeastward out over the Western Atlantic producing rain that will be light to moderate at times over parts of North Carolina and showers/thunderstorms over parts of South Carolina changing to rain through Sunday.
