nwales

In North Wales the amount of snow you can expect varies massively with both altitude and proximity to the coast. It can be raining here on the banks of the Dee and snowing in higher parts of the same town (about 100m difference in altitude). For this specific location, north westerly winds are probably best... A true northerly can bring lots of snow a little further west (which would mean a large portion of North Wales) but a north westerly means the showers can come straight up the estuary off the Irish Sea. Sometimes this set up can even mean the low lying areas end up with more as the showers hug the estuary, but that's almost unheard of! Generally this is not a good spot for snow as we're not often exposed to the wind bringing in showers and frontal snow is very much weakened by the hills and mountains further west.
