Severe storms to rumble eastward across the US through Wednesday

Damaging thunderstorms will flare up in two rounds, with the middle of the nation first at risk into Tuesday night before the severe weather dangers spread eastward at midweek.
Tuesday night's severe threat will largely be sparked by the leftover circulation of Cristobal as it races northward across the Mississippi Valley.
"As the center of Cristobal travels into southeastern Canada, the tail of the storm is forecast to produce severe thunderstorms over the middle Mississippi Valley and the lower Ohio Valley into Tuesday night," AccuWeather Senior Meteorologist Alex Sosnowski said.
These storms can threaten major metro areas such as Chicago and Indianapolis, and could spawn a few tornadoes. Damaging winds and flooding downpours are also possible.
Another zone of severe weather is possible farther west into Tuesday night as a non-tropical system emerges from the Rockies and runs into warm, humid air over southeastern Nebraska and northeastern Kansas. Very large hail can occur with storms in this corridor, in addition to isolated tornadoes and damaging winds.

As Cristobal and the non-tropical system merge and sweep into Canada by midweek, the threat for violent weather will target areas farther to the east.
A cold front that develops from the deepening and reorganization of Cristobal will march slowly eastward across the eastern third of the country on Wednesday, bringing showers and thunderstorms with it, according to AccuWeather Lead Long-Range Meteorologist Paul Pastelok.
Ahead of the front, warm, humid air will be building across the region, with some locations potentially setting new daily record highs. These steamy conditions will help to give the storms an added boost in intensity.
"Some of these storms will be on the severe side, with heavy rain and damaging winds the biggest threats," Pastelok said.
Thunderstorms can turn heavy and gusty along the entire length of the front from the central and eastern Great Lakes to the Gulf Coast, but forecasters say the highest concentration of severe weather will focus on the northern part of this corridor.
Storms may first become feisty across portions of central and eastern Michigan, Ohio and perhaps into the eastern half of Kentucky, during Wednesday afternoon, before they sweep eastward as a squall line into the evening and overnight hours.
Detroit; Columbus and Cleveland, Ohio; Pittsburgh; and Buffalo and Syracuse, New York, are some of the larger metro areas that could be rocked by the storms.
AccuWeather meteorologists say that downpours and damaging winds will be the most prevalent reports, but isolated tornadoes cannot be ruled out, especially in portions of Michigan, southern Ontario, Indiana and western Ohio.
Given that dry, sunny weather will prevail for a portion of the day ahead of the storms, those who are outside fishing, golfing or cooling off at a lake or pool will want to keep a watchful eye to the sky.
The threat for heavy, gusty storms may continue farther east as the front shifts to the Interstate-95 corridor on Thursday.
