Persistently warm weather has left its mark on a majority of the country thus far in the year 2012, including right here in the Tri-States.

To be exact, through the month of April, this year has been the warmest start to a calendar year on record, not only for St. Louis and Columbia, Mo. but also for Quincy, Ill.
