Heavy rain has been moving through the Ohio Valley, bringing a concern for flooding along a slow moving front. Some areas have been 2″ to 4″ of rain with more on the way.
Several states have been put under Flash Flood Watches from New England to the Great Lakes and Ohio Valley. 1″ to 3″ of rain is possible, with locally heavier amounts around strong storms.
A cold front will barely move overnight. Showers and thunderstorms will develop along the front, some with heavy rain. With high humidity, rainfall totals may quickly add up with slow moving storms that track over the same area.
Storms will continue to fire along the front into Friday afternoon, still producing pockets of heavy rain. As the front moves into the Tennessee Valley and Middle Atlantic, the flooding risk will diminish.
