WHY IS THIS HAPPENING? A CUTOFF LOW PRESSURE AREA (one that is not being pushed) over the Central Plains today will drift northeastward toward the great lakes Wednesday. A frontal boundary associated with this system will remain stalled to the south of the area today and tonight before lifting northward as a warm front Wednesday. A cold front will move through the area Thursday.
