It's not that it was particularly deep, 4" just isn't. However, 4" in about 2 hours on the roads does make for pretty bad driving conditions... although we've also seen that pretty frequently this season. No, it was amazing because that 4" ONLY occurred on the east side of Pittsburgh. Like, I was preparing to be snowed in at mom's when I called Mari, who was kinda amazed that I'd be snowed in.
Is Pittsburgh birthing microclimates now?
