A low pressure system will move northeastward along the Mid-Atlantic and northeastern U.S. coastline today and Wednesday. The system will produce widespread rain from portions of the coastal northern Mid-Atlantic region to New England today, which will persist into Wednesday across northern New England. Locally heavy rainfall will be possible. Across the western U.S., a Pacific storm system will move onshore today, spreading rain and high elevation snows into the Northwest and northern Intermountain Region to northern Rockies. As the system moves inland tonight and tomorrow, a deepening upper-level trough across the West will lower snow levels, with snow becoming more widespread across the interior western U.S. on Wednesday and Wednesday night. Wednesday night into Thursday morning, the system will begin to move from the Rockies into the central plains, with the potential for snow spreading into portions of the northern High Plains by that time. High pressure aloft will remain in place across the central U.S. today and Wednesday, keeping conditions generally dry with well above average temperatures. Afternoon highs are forecast to be 15 to 25 degrees above average across the plains and portions of the Upper Midwest today and Wednesday. Across the Southeast, wildfires across the southern Appalachians will continue to spread smoke across portions of northern Georgia, eastern Tennessee, and western portions of the Carolinas. Portions of these areas may experience reduced visibilities as well as unhealthy air quality. Please refer to products issued by local NWS forecast offices for further details on smoky conditions.
