A large-scale cyclonic flow pattern will remain in place across the
U.S. this evening and tonight. At the surface, a cold and dry
airmass within a large area of high pressure will be in place over
much of the nation. As a result, thunderstorms will not develop
across the continental U.S. through daybreak on Tuesday.
