Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 242 AM EST Mon Jan 17 2022 Valid 12Z Mon Jan 17 2022 - 12Z Wed Jan 19 2022 ...Heavy snow for parts of the Lower Great Lakes, Central Appalachians, and the Northeast on Monday... ...Heavy snow for parts of the Upper Great Lakes on Tuesday... ...There is an Elevated Risk of fire weather over parts of the Southern High Plains and the Southern Rockies on Monday... A strong storm over the Northeast will move into Southeastern Canada by Tuesday. On Monday, the system will produce heavy snow over parts of the Lower Great Lakes, Central Appalachians, and the Northeast. Rain will develop over the coastal and inland portions of Southern/Northern New England on Monday, too. By Tuesday morning, scattered areas of light snow will linger over parts of the Central Appalachians to the higher elevations of the Northeast. Meanwhile, a front extending from the Upper Great Lakes to the Northern High Plains will linger over the Upper Great Lakes through Tuesday morning, producing light snow over parts of the Upper Great Lakes through Tuesday. By Tuesday morning, a wave of low pressure over West-Central Canada will move southeastward to the Northern Plains. The low will move eastward across the Great Lakes overnight Tuesday and into Ontario, Canada, by Wednesday morning. The associated front will advance southward to the Southern Plains/Lower Mississippi Valley and eastward to the Great Lakes to Ohio, Middle/Lower Mississippi Valleys from Tuesday into Wednesday. The system will produce heavy snow across parts of Upper Mississippi Valley, near Lake Superior, and Michigan s Upper Peninsula on Tuesday into Wednesday. Light snow will move into parts of the Lower Great Lakes/Northeast overnight Tuesday. The western portion of the front will produce light snow over parts of the Northern Rockies into the Northern Plains on Tuesday and extend into the Central Rockies by Monday morning. Furthermore, weak onshore flow will produce light rain over parts of the Pacific Northwest and some snow at the higher elevations from late Monday afternoon into late Tuesday night. In addition, overnight Tuesday, moisture from the Western Gulf of Mexico will start to pool along the boundary over the eastern portion of the front, developing rain over parts of the Ohio/Tennessee Valleys and the Middle/Lower Mississippi Valley. On another note, Monday, warm temperatures, gusty wind, and dry fuels have led to an area of Elevated Risk of fire weather over parts of the Southern High Plains and the Southern Rockies.
