A weak storm system passing to our north on Tuesday will bring with it a risk for patchy light freezing drizzle or flurries during the Tuesday pre-dawn hours into the rest of Tuesday morning. The anticipated spotty coverage of freezing drizzle should minimize impacts, although unpaved roads, sidewalks and elevated bridges could still become slippery. Use caution if traveling Tuesday morning.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
