A front extending from the Upper Mississippi Valley to the Southern Plains and then westward to the Great Basin will move eastward off the Eastern Seaboard and southward to the Gulf Coast and the Southern High Plains by Tuesday evening. On Sunday evening, the system will produce rain with embedded thunderstorms over parts of the Northern Plains, Upper Mississippi Valley, Upper Great Lakes, and Western Ohio Valley. In addition, along the western portion of the front, light snow and rain will develop over parts of the Central Rockies from Sunday night into Monday morning. Further, overnight Sunday, light to moderate snow will develop over parts of the Northern Plains and Upper Mississippi Valley. On Monday, snow will move into the western Upper Peninsula of Michigan and light rain will be over parts of the Upper Great Lakes. Also, showers and severe thunderstorms will develop over parts of the Ohio Valley and Central Appalachians on Monday afternoon into evening. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Ohio Valley/Central Appalachians from Monday into Tuesday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. Moreover, moderate to heavy lake-enhanced snow will develop over the western portion of the Upper Peninsula of Michigan from Monday evening into Tuesday. Showers and thunderstorms will develop over parts of the northern Mid-Atlantic Monday evening into Tuesday as rain moves into parts of the Northeast. Meanwhile, gusty winds, low relative humidity, and dry fuels will contribute to a Critical Risk of fire weather over parts of the Southwest and Southern Rockies. Furthermore, upper-level energy will create rain over parts of the Southwest and rain and snow over parts of the Central Rockies Tuesday night into Tuesday evening. Elsewhere, low pressure moving away from Northern New England will produce light snow over northern Maine and coastal rain on Sunday evening into Monday morning. Additionally, coastal rain will develop over parts of Southern New England from Sunday evening into early Monday morning.
