A cold front extending from the Upper Great Lakes southwestward to the Southern High Plains will move slowly eastward to the Mid-Atlantic southwestward to the Western Gulf Coast by Tuesday morning. Moisture from the Western Gulf of Mexico will pool along the front aiding in the development of heavy rain along the boundary. Showers and thunderstorms will develop over parts of the Southern Plains on Sunday. The SPC has issued a slight risk of severer thunderstorms over this region on Sunday. On Monday into Tuesday morning, the WPC has issued a moderate risk of excessive rainfall from parts of the Lower Mississippi Valley northeastward to the Southern Appalachians on Monday into Tuesday. The associated heavy rain will produce numerous areas of flash flooding. The moderate risk means the associated heavy rain will possible produce a significant event with numerous flash flooding warnings. Many streams may flood and will potentially affect larger rivers. Farther north, the low associated with the cold front will track eastward across the Great Lakes into the Northeast. Snow will develop with this system over the region. Some lake effect/lake enhanced snow will develop downwind from Lake Ontario producing higher snow fall amounts in that area. Elsewhere, the back end of the cold front is forecast to move slowly through the Southwest leading to rain showers and higher elevations snow along and behind the front. The Central and Southern Rockies should see snow totals of 6 to 12 inches, with higher amounts in the highest peaks. The Mogollon Rim can expect a few inches of snow, and lower elevations could see light snow even into the Texas and Oklahoma panhandles. Behind the front the temperatures will be colder than average.
