Its more of a pressure-system situation. There is a good chance we could
get the pressure system that gave the snowfall in New York, because of a
system of pressure movements in the Northern Hemisphere. However, by the
time it has arrived here, it will have either weakened, or be present under
different conditions. I.E. the Low pressure will not be dragging cold air
down from Continental Canada, and across the great lakes (Lake Snow-Effect),
in our case, it is likely to stall just over Ireland so dragging quite warm
air from the Azores for a time, replaced by cold and damp conditions as the
low pushes North. The latest GFS shows no snow up to 14 days ahead, but its
validity is questionable after 6-7 days.
