This broke the previous daily record high of 87 that was set in 2004.

In the Central United States, a cold front generated thunderstorms yesterday from the Upper Peninsula of Michigan southwestward through Nebraska and northern Kansas. Numerous severe thunderstorms occurred in Wisconsin yesterday afternoon. One severe storm in Neva, Wisconsin generated wind gusts of 65 miles-per-hour, which blew the roof off a small building.

A severe storm in Dakota County in Minnesota dropped hail the size of walnuts yesterday afternoon, while Minneapolis, Minnesota was struck by wind gusts of 71 miles-per-hour. Also, tornadoes touched down in western Iowa and eastern Nebraska. The front also generated scattered thunderstorms in western Kansas and the Oklahoma Panhandle. Behind the front, isolated showers occurred in the Dakotas and northern Minnesota. Elsewhere, daytime heating produced scattered showers and thunderstorms in Arkansas, Louisiana, eastern Oklahoma, eastern and central Texas, and far southwestern Texas. Storms produced flash flooding in Houston, Texas yesterday afternoon.

In the West yesterday, monsoonal moisture generated scattered thunderstorms from the Sierra Nevada mountains of California eastward through southern Wyoming and Colorado, as well as Arizona and New Mexico.

Some areas of fog developed along the West Coast early yesterday morning, but most of the fog had dissipated by late morning.

NATIONAL WEATHER FORECAST

In the East, an upper-level disturbance will produce scattered showers and thunderstorms across portions of the Great Lakes, and the Ohio and Tennessee Valleys. There will be a chance for severe weather, with storms capable of producing frequent lightning, strong winds, large hail, and brief downpours. Rainfall amounts of around a quarter of an inch will be possible. Further south, partly cloudy skies with afternoon and evening showers and thunderstorms can be expected across the Southeast and Florida. A few strong thunderstorms, along with rainfall amounts of near an inch will be possible with this activity. Otherwise, high pressure will allow for fair skies and dry conditions across the Northeast and the Mid-Atlantic region. High temperatures will reach into the 70s and 80s across the Great Lakes region and the Northeast; and into the mid 80s to the lower 90s through the Ohio and Tennessee Valleys, the Mid-Atlantic region, the Southeast, and Florida.

Across the central part of the country, a low pressure system will produce showers and thunderstorms across the Upper and Middle Mississippi Valley, and the central Plains. There will be a chance for strong to severe thunderstorms, capable of producing frequent lightning, strong winds, large hail, and heavy downpours. Rainfall amounts of an inch will be possible. Elsewhere, an upper-level disturbance will bring the chance for scattered showers and thunderstorms to the southern Plains and the Lower Mississippi Valley. A few strong thunderstorms, along with rainfall amounts of up to an inch will be possible with this activity. Otherwise, high pressure will allow for fair skies and dry conditions through the northern Plains. High temperatures will reach into the 70s and 80s across the northern and central Plains, and the Upper Mississippi Valley; and into the mid 80s to the 90s through the southern Plains, and the Middle and Lower Mississippi Valley.

In the West, partly cloudy skies with afternoon and evening showers and thunderstorms can be expected across the central and southern high Plains, the central and southern Rocky Mountains, the Great Basin, and the Desert Southwest. Strong winds and small hail may accompany a few of the stronger thunderstorms. Areas of flash flooding will also be a concern as rainfall amounts of a half of an inch may fall in a very short amount of time. Otherwise, fair skies and dry conditions will prevail throughout the northern high Plains, the northern Rocky Mountains, the Pacific Northwest, and much of California. High temperatures will reach into the 60s and 70s along the coastal region of the Pacific Northwest; into the 80s and 90s through the high Plains, the Rocky Mountains, the Great Basin, coastal California, and the Pacific Northwest; and into the upper 90s to near 115 through the Desert Southwest and much of interior California.
