Tuesday, March 26th marked the 18th snow day for Johnson County School students. Thirteen snow days are already built into the school year calendar, but an extension of time each day gives the school system additional days that are available to be used in case of inclement weather. The students have already made up two snow days this year. According to Johnson County Director of Schools, Morris Woodring, there is a possibility the School Board could consider tacking on additional days to the end of the school year. Tuesday and any future inclement weather days will need to be made up.
