Sorry trick-or-treaters and parents, you`re going to want that large umbrella for Halloween. A wet period is in store. A cold front will move through the region Wednesday before stalling out near the Ohio-West Virginia border. After an initial round of rain Wednesday, steady and moderate rainfall is expected Wednesday night and Thursday. More rain will fall overnight Thursday. The expected storm total rainfall from this system exceeds 2.5 inches in the flood watch area, with a maximum of over 4″ in Owen and Grant counties, extending northeast through Falmouth to the southern border of Clermont and Brown counties.
