I will tell you why. This low is sucking up warm air from sea, and then pushing it westwards, where ever the temperature and dewpoints are marginal its pushing them
to far up , so it ends up falling as rain and not snow. However in heavier precipitation (rain) it is turning to snow and pushing the temps and dp down. Unfortunately this
is what we where to expect anyway. Some times or often times the synoptic set ups that you think are right, just never deliver, and places which should not be getting
the snow, end up getting it.
Unfortunately outside of marginality it is not a problem, but thanks to the irish sea there is always the element of it pushing warm air inland, and the only way to avoid it,
to some extent is to get to higher ground. For example at 220m asl, your chances of snow will have increased by about 50/60%, go higher and you get the idea the % rate
goes up, the only thing missing then is the precipitation, since your not really going to be marginal temp or dp at elevation.. this is what living within 15km coast will do for you,
you have a significantly higher chance of rain than say 15km+ inland.
if you really want snow, you should look for properties in northern scotland, highlands, you can be guaranteed snow there every year.
