Weather

A mass of dry air will linger Thursday over much of New England and the upper part of the Mid-Atlantic. Patches of dense morning fog will give way to a dry and partly sunny day across much of the region.

Hot and humid conditions will linger from the Southeast coast to the central and southern Plains. While much of the area should be dry, a few storms are expected along the Gulf Coast, and some of them could cause urban flooding.

Drenching rain and thunderstorms will extend from the northern Plains to the Great Lakes. This may result in flash flooding and damaging storms across the area, some of which has been hit hard by torrential rain and flooding on multiple occasions this summer.

Tropical downpours are expected to occur from New Mexico to parts of Arizona and Colorado. Much of this moisture will come from a tropical depression that formed over the Gulf of California on Wednesday. The rain will drift east over the southern Plains to end the week.

Much of the rest of the West can expect dry weather and some sunshine, with storms across southwestern Canada.

FOCUS: Rivers Continue to Rise in the Carolinas

While the extreme rainfall from former Hurricane Florence has long since departed, major rivers across southeastern North Carolina and northeastern South Carolina continue to rise. The Waccamaw River near Conway, South Carolina, is projected to exceed record levels this weekend.
