That happens here every storm. Last storm was supposed to be like 8-12 with up to 25 in the foot hills..... Yeah we got like 2 inches...... The few before that....well...... We got hammeredit's a frequent phenomena on the east coast. snow accumulations being wildly incorrect. one time last year we were "supposed" to have 10-12", ended up with barely a dusting. 2 years ago we had a storm where 3" wound up being 8".
