Weather across America
(NATIONAL) Heavy snow and pockets of rain/freezing rain over parts of the Upper Mississippi Valley and Upper Great Lakes, snow over the higher elevations over the West, and elevated and Critical Risk of fire weather over the Southern High Plains.
Low pressure and an associated front over the Central Plains will move eastward off the Mid-Atlantic Coast by early Tuesday. The system will create an area of rain and heavy snow over parts of the Upper Mississippi Valley/Upper Great Lakes on Sunday evening into Monday morning. Along the rain/snow line, rain/freezing rain pockets will develop over the region.
On Monday, rain and snow will continue over the Great Lakes and Ohio Valley, with the rain and snow moving into parts of the Mid-Atlantic by Monday evening into Tuesday. Likewise, there will be a region of rain/freezing rain along the rain/snow line over the Mid-Atlantic. On Tuesday, light snow showers will continue over parts of the Northeast. The combination of snow and ice may cause hazardous road conditions.
Meanwhile, an area of upper-level energy will move onshore over the Pacific Northwest and slowly expand eastward to the Northern Plains by Tuesday evening. The upper-level energy and associated weak onshore flow will produce coastal rain and higher-elevation snow over Pacific Northwest and California through Tuesday afternoon.
In addition, snow will develop over parts of the Northern Intermountain Region, Great Basin, and Northern/Central Rockies through Tuesday. By Monday, the upper-level energy will create light snow over parts of the Northern/Central Plains Sunday evening into Tuesday evening. The snow will result in reduced visibility and hazardous driving conditions.
Furthermore, multiple areas of low pressure will move along a stationary front extending from the Southwest to the Southern High Plains through Tuesday. As a result, the SPC has issued an Elevated and Critical Risk of fire weather over the Southern High Plains from Sunday into Tuesday. Strong wind, low humidity, and dry fuels have contributed to the areas of Elevated and Critical Risk of fire weather.
