in the heavier ice accumulations.

the region on Wednesday night and Thursday bringing another chance for
freezing rain or freezing drizzle and some snow to northern areas.
Then after a brief break Friday, another system will move across the
area Friday night and Saturday. Highs will be on the cool side with
