Under a new measure approved by Baltimore County's board of education earlier this month, if the heat index reaches 90 degrees, all non-air conditioned public schools are required to close.
The policy goes into effect if the heat index is forecast to reach 90 degrees by 11 a.m. If the heat index is forecasted to reach 90 degrees by 2 p.m., those schools will get out two hours early.
