Further west, an area of low pressure approaching the Pacific Northwest will bring a risk for heavy rain across portions of Washington and Oregon. Into Wednesday, an area of low pressure will bring showers and thunderstorms to portions of the Gulf Coast. Rain will continue for portions of the Northwest as the area of low pressure approaching the region moves inland through the end of the week.
Heading into Thanksgiving, showers and thunderstorms will continue for portions of the Southeast as an area of low pressure continues to move eastward.
