National Weather Summary for Wednesday, July 27, 2016

by David Moran, on Jul 27, 2016 11:15:51 AM

Isolated thunderstorms are possible across the Northern and Central Plains on Wednesday, as instability builds during the day. Across the Mid Atlantic, thunderstorms are possible along a stationary front. A cold front pushing into Maine will allow for the development of thunderstorms. There will be the potential for thunderstorms across portions of Arizona this afternoon. Thunderstorms will bring the potential for heavy to excessive rainfall to portions of the Southeast. Into Thursday, thunderstorms will once again be possible for portions of the Plains and Mid Atlantic. Activity in portions of these regions will continue into Friday.
