Warmth will extend from the southern Plains and the Southeast to the Ohio Valley, the Mid-Atlantic and much of New England. The clockwise flow around a high-pressure system off the East Coast will pump warm and humid air up from the Gulf of Mexico. Much of the region can expect sunshine. Tropical moisture will produce clouds and spotty showers over parts of South Florida.

Thunderstorms and possible severe weather, including isolated tornadoes, will extend from west-central Texas to western Oklahoma, central and eastern Kansas, southeastern Nebraska, northern Missouri, much of Iowa, northwestern Illinois and southern Wisconsin. Tornadoes are most likely to develop in western and central Oklahoma later in the day. Some of the storms may also bring damaging gusts, large hail, lightning strikes and flash flooding. Lighter showers will occur over the lower Great Lakes and northern Maine.

Much cooler air will continue to prevail over the West. Spotty showers and afternoon thunderstorms will extend from southern Wyoming to Southern California and parts of Arizona and New Mexico. Much of Washington, Oregon, northern Idaho and Northern California will be sunny.

FOCUS: Weather Pattern Next Week

Temperatures are expected to be well above normal next week across much of the West, including southwestern Canada. A series of fronts will bring cooler air to the Great Lakes and New England. The Mississippi and Ohio Valleys may turn drier.
