March 2015 summary

Early March was cold and blustery with rain and a little wet snow, thanks to a collection of low pressure systems north of Scotland. High pressure formed to the south of the UK on the 4th and brought clear skies and an air frost (just) early on the 5th. Daytime temperatures rose in the sunshine, and the 7th saw what turned out to be the highest temperature of the month at 16.5°C.

A deep low on the 9th generated 100kt winds in Scotland, but nothing more than a blustery shower here as the cold front passed though. The following two weeks were generally quiet with high pressure over Scandinavia, but that system drew in a cold easterly which kept temperatures down with a second air frost on the 23rd.

The settled spell came to an end on the 28th as another group of lows approached Scotland, and the 29th was a day of wind and rain.  A total of 12.6mm made this the wettest day of the month with wind gusting to 40kts. Another deep low crossed Scotland on the night of the 30th/31st with a gust of 43.5kts at 0232 – not far off the speeds reached during the St Valentine’s Day storm of 2014. The wind continued for most of the 31st.

The average temperature of 7°C and rainfall total (49mm) were both normal for March, and the gales of thelast few days offset the quiet spell in the middle of March, to give an average wind run too.
