The deepening trough will lower snow levels over the mountainous regions producing heavy snow over the Cascades and Sierra Nevada Mountains starting Tuesday evening and going through Wednesday. As the trough moves east, the heavy snow moves into the Wasatch Mountains, Uinta Mountains, and Central Rockies from Wednesday evening into Thursday. The winter weather has prompted Winter Storm Warnings and Winter Weather Advisories over the Pacific Northwest, Sierra Nevada Mountains, and Northern Rockies. The snow will result in reduced visibility and hazardous driving conditions. In the meantime, moisture will move northward over the Plains into the Upper Midwest in earnest Wednesday evening into Thursday. The moisture will intersect a front moving westward with an upper-level trough producing showers and thunderstorms over parts of the Upper Midwest and Southern Plains on Thursday afternoon. In addition, upper-level riding ahead of the upper-level trough will produce temperatures 15 to 25 degrees above average over parts of the Northern/Central Plains. Furthermore, strong gusty wind and low humidity will develop over parts of the Plains that have prompted the SPC to issue an Elevated Risk of fire weather conditions over parts of the Northern/Central High Plains from Tuesday into Thursday morning.
