May Weather

May 2019 Monthly Report – Not really settled yet

May 2019 Summary

May opened disappointingly cool, with the preponderence of winds from an Northerly and Easterly sector, the direction no-one wants at this time of the year. There was no real warmth until the 13th and then only for three days! Temperatures did recover a bit in the second half, to give an overall mean of 10.9 degC, which is still on the cool side for May.

The rainfall total was also on the low side for May, continuing the rather dry Spring. Rain was well spread, with only two short dry periods. The wettest day was the 8th, with 12.2mm. Some areas of the North East had very heavy thundery showers towards the end of the month, with reports of a funnel cloud from the Bishop Auckland area on 28th.

There was more anticyclonic influence in May than low pressure, but it was just drifting about in the wrong place to offer much of an early taste of summer. Ah well, let’s see what June brings.

Funnel Cloud seen over North East England – 28th May 2019

by

The report above appeared in the Northern Echo newspaper on 29th May 2019.

The axis of funnel clouds may be vertical, inclined (as seen here), or sometimes long and sinuous.  In the UK it is usually tens of metres in diamater (not huge). It is much rarer for funnel clouds to touch the ground and that is when they become tornadoes, but it does happen occasionally. Most UK tornado reports come from The Midlands, Central, Southern and South East England and East Anglia. Our very own Tornado Alley!

If you see a funnel cloud or suspected tornado, you should report it to TORRO (Tornado and Storm Research Organisation). They catalog such stuff and produce stats and mapping.

There are 40 tornadoes per year recorded on average in the UK. England has the highest reported incidence of tornadoes per square mile in the World. That usually surprises a few people, but it’s true!

The longest ground track by a tornado in the UK was in May 1950, when a tornado traveled 107km from Buckinghamshire to Cambridgeshire.

A cracking Spring day in May 2018. From Prebends Bridge

Durham Cathedral and The River Wear from Prebends Bridge

A gorgeous day in May 2018. View from Prebends Bridge looking towards Framwelgate Bridge. It was the precursor of a fantastic summer. The Durham Cathedral tower work continues, still shrouded in it’s protective covering. The stonemasons are replacing weathered stone blocks at the top of the Main Cathedral Tower, as they have become dangerous.

Prebends Bridge washed away in November 1771

 

The previous Prebends Bridge was washed away in a catastrophic flood on 17th November 1771. It was a storm that proved fatal to many North East bridges on both the Tyne and Wear, as well as many smaller tributaries.

18th May 2013 – A very wet day with flooding

by

May felt disappointing although in fact mean air temperature was just a little above average; daytime temperatures were just a little above average and night-time temperatures just a little below. Rainfall was well above average so that the running 12-month total remained above 1000mm for the 6th month in a row, a remarkable sequence. There were heavy falls on the 15th (21.4mm) and especially on the 18th (40.8mm), the latter causing extensive flooding in the Durham area. Rainfall intensity was extraordinary on the morning of the 18th with 12.2mm in one hour (08:00 – 09:00 BST) and 10.2mm the next hour.
