I'm located at 282 feet above sea level. Leeds city centre varies a lot topographically, areas close to the river go below 30 metres, while areas close to the Inner Ring Road go up to 70 metres. According to Google earth, parts of Castleford are as low down as 15 metres (49 feet), so it's no surprise that it usually does worse than Leeds for snowfall (you may remember posts from Castleford/Normanton saying they had rain before it turned to snow, while it was all snow in Leeds).
In general though, West Yorkshire is a good place for snow, and we do well in marginal situations.
