Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 310 PM EST Sun Feb 15 2015 Valid 00Z Mon Feb 16 2015 - 00Z Wed Feb 18 2015 ...Heavy snow for parts of the Middle Mississippi Valley eastward across the Southern Ohio Valley into parts of the Central Appalachians... ...Freezing rain possible for parts of the Lower Mississippi Valley and Tennessee Valley... A wave of low pressure over the Southern Plains will move eastward to the Central Gulf Coast then northeastward to just off the Mid-Atlantic Coast by Tuesday morning. The system will pull moisture off the Gulf of Mexico that will overrun the associated boundary producing light to moderate rain over parts of the Southern Plains that will move to the Lower Mississippi Valley and expand into the Southern Appalachians by Monday evening. By Tuesday morning, the light to moderate rain will move off Southern Mid-Atlantic/Southeast Coast. In addition, snow will develop over parts of the Central Plains/Middle Mississippi Valley by Sunday evening that will become moderate snow over parts of the Lower/Middle Mississippi Valley by late Sunday night. The moderate snow will move into the Middle Mississippi Valley and expand into the Southern Ohio Valley by Monday morning. Similarly, the moderate snow will also expand into parts of the Central Appalachians by Monday evening and move into Southern New England by Tuesday morning. Furthermore, a band of rain/freezing rain and sleet will develop between the rain/snow line from parts of the Middle/Lower Mississippi Valley spreading into parts of the Southern Appalachians by Monday evening. Additionally, showers and thunderstorms will develop over parts of the Western Gulf Coast and the Lower Mississippi Valley by Monday afternoon/evening moving out over the Gulf of Mexico by Tuesday. Meanwhile, upper-level energy sinking southward over the Rockies will aid in producing light snow over parts of the Northern/Central Rockies through Monday evening. Moreover, a front over West-Central Canada will move southeastward to the Upper Great Lakes/Central Plains by Tuesday. The front will also bank up next to the Northern/Central Rockies on Monday evening into Tuesday. The dynamics of the boundary and upslope flow from high pressure over West-Central Canada will aid in producing light snow over parts of the Northern/Central High Plains that will move to the Central High Plains/Central Plains by Tuesday morning. Light snow will also develop over parts of the Upper Great Lakes along the associated front Monday evening into Sunday. Elsewhere, deep low pressure over the Canadian Maritime Provinces will move northeastward to Eastern Canada by Tuesday. The system will produce light snow along the parts of New England Coast will wind down overnight Sunday. Likewise, high wind associated with the deep low will slowly diminish by Tuesday.
