Severe storms stretching across Upper Midwest

More severe weather is expected Wednesday for much of the U.S.

More than 120 damaging storms were reported from Montana all the way to Florida on Tuesday, a barrage that included 70 mph winds from Texas to Illinois, golf ball-sized hail Nebraska and up to half a foot of rain in parts of southern Iowa.

In parts of southern Texas that saw a foot of rain overnight on Monday, there were disaster declarations on Tuesday as authorities rushed to provide flood relief.

Storms are expected to continue on Wednesday as a new system makes its way out of the West. Severe storms could stretch from Washington state to Illinois.

Damaging winds, hail and a few tornadoes are likely to be biggest threats.

Although many northern U.S. cities have had a pretty mild spring and early summer -- cities including Denver, Chicago and New York have yet to hit 90 degrees -- that may soon change.

A full-blown heat wave -- meaning at least three days with 90-degree highs -- is now expected in Philadelphia and Washington as things head up along the East Coast.
