UK’s Low Pressure Dominated Summer 2020 Ends Stormy!

Written by on August 24, 2020 in Rest of Europe, United Kingdom & Ireland with 0 Comments

Summer 2020 will be remembered as ‘very changeable’ but with extremes of wet, cool and hot. In terms of 500mb pattern, the summer forecast has been good with low pressure the rule.

Actual 500mb geopotential anomaly from 1 June – 10 Aug.

While June was slightly warmer-than-average, July was slightly below average and as forecast, the coolest since 2012. While August will be comfortably warmer-than-average thanks to be exceptional warmth of the opening 7 days, the month overall will, like June and particularly July have been dominated by low pressure.

Following the early August heatwave, an unusually strong, zonal jet stream of October strength has driven frequent spells of wet and windy weather to the UK and Ireland.

The opening 7 days to August was record warm which the final 7 sees a series of autumnal lows. Storm Ellen brought widespread gales and heavy rain just days ago and today we contend with another unusually deep low similar in strength to Ellen which will bring further heavy rain and damaging 50-60, locally 70 mph winds.
