UK & IRELAND: Driest September On Record?

Written by on September 15, 2014 in Rest of Europe, United Kingdom & Ireland with 0 Comments

Bertha took summer away from us back at the end of July but another former hurricane, Christobal brought it back and ever since, well it’s been VERY dry and where sunny, warm but by no means unprecedented.

According to a BBC tweet last evening, yesterday marked day 6 where nowhere in the UK recorded more than a mm of rain and this week looks unlikely to produce anything particularly significant.

That’s why this headline is quite believable…

Last September was also warm and very dry. Often when you get a persistent pattern whether wet or dry during the summer season, you often get a continuation into early autumn before a turnaround takes place.

This will probably wind up in the top 5 driest UK/Ireland September’s if not a close contender for driest of all given the fact that we have less rainfall than previously thought this week and we look likely to see this stubborn high pressure zone sticking around for much of the rest of the month as another hurricane tracks north keeping the ridge ‘pumped up’.

It’s been spitting of rain here in Lennoxtown today but it’s safe to say I don’t think I’ve seen much rain (if any) in about 10 days.

This model had a strong mean ridge directly over the UK, shielding us from the more typical wet, Atlantic weather which has been dominant across more southern parts of the continent.

500mb height anomalies day 3-10 off the ECMWF shows no budge in mean ridge!
