Watertown has actually had multiple great LES events in recent years. Buffalo used to get a good event every few years, but it has been over a decade since a big event hit the city from downtown to the north. There have been several great chances for a big snow on the last five years, but every time there’s a great set-up, one variable - shear, moisture, flow, temp profile - changes during the nowcast.
It’s either a very bad run of luck or a climatological problem. Unfortunately, it keeps happening. Last year we got bailed out by several moderate synoptic events in the last third of the season, but we have had a run of anomalously low LES years recently.
