I am surprised Frederick County (and Carroll too) doesn't split school decisions like Baltimore County does.
LWX even went as far to split the counties up years ago for forecasting purposes, because you're right @Mrs.J the northern part of Frederick is different than the southern part. Elevation differences, etc.
Either way, they should have let out early. The western counties were always under the flooding rain threat, and it was days of forecasting for it. It shouldn't have come as a surprise. ESPECIALLY coming off the wet weeks we've had prior to this week.
