Unless you're somewhere else, the metro got that big storm on March 7-8th, not mid-month.
I also don't think anyone is claiming it can't snow in mid-March. We can get a 6+ inch storm in April for that matter.
Point is, after the equinox in just over a month, the chances of accumulating snow are drastically reduced. Between now and then is when we'd need to boost totals to average or better to make this a decent season.
