Wintry weather arrived on the 26th with showers of hail and snow around the summits, heaviest in the afternoon. On the 27th snow was lying thinly on the northern slopes of the Carneddau with icy deposits as low as 1800 ft in places. Slight snow lying above 3000 ft with ice at 2250 ft on the 28th and ice precipiation showers in the evening.

Observations are made as near to 0900 GMT as possible. I have a good view from Llansadwrn, weather permitting, across the Menai Strait towards the Snowdonia Mountains. I can see the northern slopes of the mountain range from Moel Eilio (west of Snowdon), Snowdon summits (Yr Wyddfa and Crib Goch), the Glyderau and Carneddau to Foel-fras and Drum to the east of the range near the Conwy Valley. With the aid of binoculars I make daily records that include any ice precipitation observed, the lowest altitude of snow lying at ( >= 50% cover), at ( >= 30% cover) and snow patches. I aim to update the diagram during the season at least twice weekly if there is any snow.
