Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 348 PM EDT Tue Sep 30 2014 Valid 00Z Wed Oct 01 2014 - 00Z Fri Oct 03 2014 ...There is a slight risk of severe thunderstorms over parts of the Northern Plains... ...Heavy rain possible over parts of the Central Plains/Middle Mississippi Valley... A dissipating front over Florida will aid in producing showers and thunderstorms over the area through Thursday morning. In addition, and upper-level low over the Great Lakes will move eastward to near Cape Cod by Thursday. An associated weak front will dissipate overnight Wednesday. The energy will aid in producing showers and thunderstorms over parts of the Mid-Atlantic and parts of New England Coast Tuesday evening into Thursday. Meanwhile, a front extending from the Northern Plains southward to the Southern High Plains will move slowly eastward to the Upper Great Lakes to the Southern Plains by Thursday. Moisture will pool along the boundary aiding in the development of showers and thunderstorms from parts of the Upper Mississippi Valley to the Southern Plains Tuesday into Thursday. Rain will develop over parts of the Northern High Plains and lift northward into South-Central Canada by Wednesday afternoon. Another area of rain will develop over parts of the Upper Great Lakes Wednesday evening into Thursday morning. As moisture flows northward out of the Gulf of Mexico, showers and thunderstorms will develop over parts of the Central Gulf Coast/Lower Mississippi Valley early Wednesday morning into Thursday morning. Additionally, upper-level energy over the Northern Intermountain Region will move southeastward to the Central Rockies by Thursday. The energy will produce areas of rain over parts of the Great Basin/Central Rockies through Wednesday evening. Areas of rain and snow will develop at higher elevations over parts of the Northern/Central Rockies also through Wednesday evening. A third piece of upper-level energy entering the Northern High Plains by Thursday morning, from Canada, will produce rain over parts of the Northern High Plains.
