On the 4th April 1994, Easter Monday, that year, cold polar maritime air flooded the country giving wintry showers in many places. What is interesting was the direction of the wind flow, WNWly and not a Nly flow. This shows that even at this time of the year, wintry weather is not just restricted to proper northerly or easterly flows.
I remember a band of wet snow moving through during the morning and then we had snow showers for the rest of the day
