Severe storms possible in Midwest

First day of meteorological fall marked by above-normal temps. across much of U.S.

Above-normal temperatures are forecast across much of the contiguous U.S. on Tuesday and in some cases will be as much as 10-15 degrees above average for this time of year. Afternoon highs could reach 90 or higher from the Great Plains to the Eastern Seaboard. One exception will be across parts of the Pacific Northwest. Remember to practice heat safety if you plan to spend extended time outside.

...Heavy rain possible over parts of Florida...

High moisture content air over parts of the Southeast and upper-level energy moving over parts of Florida will aid in producing showers and thunderstorms over the parts of the Southeast Coast and Florida through Wednesday evening. In addition, moisture moving northward out of the Western Gulf of Mexico and upper-level energy will produce showers and thunderstorms over parts of the Western Gulf Coast also through Wednesday evening.

Pockets of upper-level energy over parts of the Ohio Valley into the Mid-Atlantic and over the Central Plains moving to the Upper Great Lakes will aid in producing areas of showers and thunderstorms over parts of the Upper Great Lakes/Upper Mississippi Valley to the Central/Southern Plains through Wednesday. Likewise, areas of showers and thunderstorms will develop over parts of the Ohio Valley into the Mid-Atlantic.

Meanwhile, a front moving onshore over the Pacific Northwest will move inland to the Northern High Plains/Northern Intermountain Region re-enforcing a stalled boundary over the Northern High Plains. The boundary will produce rain over parts of the Pacific Northwest on Tuesday. Behind the front, onshore flow will produce rain over parts of the Northwest Coast similarly on Wednesday. Additionally, monsoonal moisture and daytime heating will trigger showers and thunderstorms over parts of the Southern/Central Rockies and parts of the Southwest/Great Basin during the afternoon and late evening hours on Tuesday and Wednesday.
