Weather Underground Forecast for Wednesday,June 29,2016

Active weather will threaten the central Plains on Wednesday, while thunderstorms affect the Gulf Coast and the East Coast.

An area of low pressure will inch across the Plains. This system will produce strong to severe thunderstorms over parts of the northern and central Plains. Severe thunderstorms will be possible in southern South Dakota and Nebraska. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Heavy rain may lead to flash flooding in south central Nebraska and Kansas. Just to the north, a cold frontal boundary will swing across the northern Plains. This frontal system will initiate showers and thunderstorms from the upper Mississippi Valley to the upper Intermountain West.

Monsoonal moisture and daytime heating will trigger isolated showers and thunderstorms across the Four Corners and the Sierra Nevada. The bulk of these storms will fire up during the second half of the day. Above normal temperatures will persist in parts of the Southwest. Heat advisories will remain in effect for central Nevada and southern California through Wednesday evening.

Meanwhile, an area of low pressure will move northeastward across New England and southeast Canada. This system will usher rain and thunderstorms over a large part of the Northeast. A cold frontal boundary associated with this system will generate showers and thunderstorms across the Mid-Atlantic, the Southeast and the Gulf Coast. High pressure should keep most of the Midwest clear of precipitation on Wednesday.
