NATIONAL SUMMARY

As a potent storm system pushes across the Great Lakes

region today, thunderstorms capable of producing high winds,

hail, flash flooding and a few tornadoes will advance to the

east across the Midwest. Meanwhile, more downpours capable

of producing flash flooding and locally severe thunderstorms

will extend from Missouri to the Carolinas. More severe

storms are forecast to erupt in parts of Wyoming and

Colorado late in the day before pushing onto the central

Plains at night. Much of New England and the coastal

mid-Atlantic can expect a dry day. Cooler and less humid air

will expand over the northern Plains. Meanwhile, very hot

air and blazing sunshine will continue from much of Florida

to interior California. More temperate conditions are in

store for the Northwest with abundant sunshine.
