"The best chance for the least cloudiness Thursday night should be from parts of the mid-Atlantic states to the Ohio Valley and central Plains. Parts of the Florida Peninsula and Deep South Texas should also be relatively cloud-free.
However, areas of the Rockies and Great Basin from Montana and Idaho to Nevada and Arizona may have showers and higher-elevation snow to deal with.
Also, a veil of high clouds could blanket the northern tier from the Dakota to New England."
WTF is the Ohio Valley? I get Ohio, but what's the valley? Ohio's flat.
