It was all about the night time low temps.
For all of my life I have always been colder than MDT for low temps. The only exceptions are special situations involving a cold front that came through MDT but not through my area yet OR a winter storm situation where warm air invades my area quicker off the ocean. Outside of that, I'm going to be a few degrees colder than MDT 95% of the time. For whatever reason, this winter MDT was running consistently about 3-5 degrees colder than down here almost every night. No idea what changed, but that's where the difference happened.
My original point was much more specific to snowfall because you were calling a bust for Elliott prematurely and it came back to get you.
