I got a little fed up with hearing every BBC weather presenter churn out the phrase “this are of low pressure is very unusual for the time of year” and decided to investigate the truth of the matter. Of course, it all depends on what you term “unusual”, I know personally that as I get older how easy it is to forget past events, and that the low now tracking into Ireland might not be that unusual at all, and that’s when gridded MSLP data and weather statistics drawn from that data come into their own. More information and plotted charts here.
Was it a sting jet? I was camping in North Devon at the time, and judging by the amount of damage on the site it was particularly windy!
