Some storms are firing north and east of a "leftover low" of sorts; a spinning in the middle of the atmosphere created from storms in Oklahoma last night. These "MCV's" are often the trigger for storms the next day as they drift along.
The wind shear needed to keep supercells held together is still low this morning over the area allthough these MCV's have a way of producing small wind features which go undetected and may help overcome this to a certain extent.
Areas from Springfield northeast and later anywhere to the east should watch these storms as they are capable of hail and gusty winds.
