North Yorkshire not Yorkshire and even then, there is a massive difference between Teesside and what's probably classed as North Yorkshire, mainly being the height difference. Thornaby, at one point was actually classed as North Yorkshire.
What someone says and what happens are two totally different things though. I'm still going for rain/sleet event. I'm more than willing to be proved wrong and I hope I am.
I'm going for rain, for me in Thornaby anyway. This has nothing to do with my knowledge of the weather, just the fact that this area doesn't really do well with snow most of the time. I can just see all these people wanting laying snow and being let down when the rain arrives and turns just to sleet.
