November and Autumn 2016

Weather Report – November and Autumn 2016

In Plymtree November was an interesting month weather-wise. The month started mild and dry, there was then a brief cold spell before the weather turned unsettled from the 8th. Between the 18th and the 21st we experienced some very interesting weather. On the morning of the 18th during a heavy shower the temperature began to fall and the rain gradually turned to sleet then large flakes of wet snow for a while. Although it didn’t lie in the village the snow was laying on the hills near Tiverton and on the Blackdowns. Overnight on the 19th/20th the first named storm of the winter, Angus, hit with very heavy rain and strong winds. This was closely followed on the 21st by another depression which brought yet more heavy rain and resulted in localised flooding with the village almost cut off. After this the weather quietened down and there was no further rainfall from the 23rd for the rest of the month. The total rainfall I measured for the month was 147.3mm. The average (1981-2010) at Dunkeswell Airfield is 115.9mm. This means that we received 127% of the Dunkeswell average. The total autumn (Sep, Oct and Nov) rainfall I recorded was 265.4mm which compares to an average of 315.1mm at Dunkeswell or 84% of average. The wettest day of November was the 19th with 46.0mm, closely followed by the 21st with 33.0mm. There were 11 rain days (rainfall ≥ 1mm), which compares to an average of 14.8 days for Dunkeswell. The highest temperature I recorded during November was 15.1°C on the 15th. The lowest temperature, -6.7°C was recorded on the 30th. The strongest wind during November occurred overnight on the 20th when a gust of 38.7mph was recorded during the passage of storm Angus.

(Please note because of the heavy rainfall on the 19th the axis on the graph below has changed from that normally shown: i.e. 0-50mm rather than 0-25mm).
