Exceptional July weather coming to an abrupt end

July so far has been exceptionally dry, warm and sunny, but a notable change in the weather is expected in the next 36 hours.


At Linton-on-Ouse in North Yorkshire, less than 2mm of rain has fallen so far this month.


It’s fair to say that farmers and gardeners are now very keen for rain, although reservoir stocks are still healthy in Yorkshire following last summer’s washout.


The hot spell has, understandably, dominated the media.


It has been the only prolonged hot spell since July 2006 – which itself turned out to be the hottest July on record on Met Office figures which date back to 1910.


Temperatures at Heathrow and Northolt this afternoon reached 33.5C (93F) making it the hottest day anywhere in the UK since July 20th 2006.


But the spell of hot weather has not been in the same league as that recorded during the record-breaking summer of 1976.


That year, temperatures were higher than 32C (90F) for 15 consecutive days from late June to early July somewhere in the UK.


That said, with temperatures soaring again today, we’ve had 17 consecutive days with temperatures exceeding 28C, equalling the sequence set in 1995, but not as long as the sequence set in 1997 (19 days)


In 1976, there were 22 such days.


But with the jet stream expected to slip southwards from its current position, the weather will be more unsettled for the rest of July and into early August.


Warnings are in place for the next 36 hours, as developing thunderstorms could lead to local flooding as a result of torrential rain falling on to the sun-baked land.


After the thundery breakdown it will though remain warm into the weekend, and although more unsettled, there will still be some sunshine at times - together with a risk of further heavy showers.


Here in Yorkshire and Lincolnshire next week could feel very different, with temperatures closer to normal for the time of the year as low pressure dominates the our weather bringing rain to most areas.
