Damaging winds and large hail could race halfway across the country the final weekend of July.
Severe weather may hit states from Nebraska and Kansas all the way to Virginia and New Jersey and everyone in between. A shortwave -- think of it as a small low pressure system halfway up the atmosphere -- and some strong winds aloft will create conditions favorable for severe weather.
Saturday's severe weather threat stretches from the Plains to western New York, leaving the majority of the Midwest in its crosshairs.
With a severe weather setup like this, the greatest chance for any damage will likely come from winds, but some large hail is also possible.
Beginning Saturday afternoon, scattered severe thunderstorms will begin to develop near the western edge of Missouri, then travel east, so some of these storms will last into the overnight in places like eastern Ohio and Pennsylvania.
On Sunday, parts of the Midwest are still at risk for severe weather, but the threat also expands to include parts of the Mid-South and the East Coast.
Sunday's setup is similar, but all the ingredients are running into slightly warmer, more humid, and therefore more unstable air.
We could see a severe mesoscale (larger, organized) storm develop, bringing strong winds, large hail and there's even a small possibility for a tornado or two.
This weekend's severe weather is affecting a lot of people, but residents in Indiana and Ohio should pay especially close attention since the weekend's risk areas overlap both of those states.
