Summer-like warmth continues...
For those beginning their long, holiday weekend travels, dry, increasingly warm weather will overspread much of the eastern U.S., with daytime highs averaging more than 20° above normal from the Ohio Valley into the Northeast.
On the Plains, a slow-moving cold front will bring occasional showers to the northern half of the region, while summer-like heat prevails on the southern Plains until the front arrives on Friday. Locally heavy rain associated with the front will impact the northern Delta and central Corn Belt over the weekend.
Out west, a pronounced trough (southward dip in the jet stream) will maintain cool, unsettled conditions from the Rockies to the Pacific Coast, with heavy rain and mountain snow likely in portions of the central Rockies and Pacific Northwest.
