It wasn't.. It was a.robust upper level low that tracked just south to create this setup. A lot of the snow that fell in the mountains was rain in the foothills before switching over
Most painful storm of my lifetime. Not even close. Made worse by the fact that we had barely had any snow in the years prior.. that was insult to injury.
I always lose sleep when there's storms to track.. how I wish the Euro came out an hour earlier.. I hope to see less of a downsloping signature on future runs.. Right now my area is in a definite precip minimum
