There was some noisy weather across the Aylesbury Vale late last week and over the weekend, as heat and humidity sparked some spectacular thunderstorms.

The heat arrived in earnest last Thursday with temperatures across the Vale soaring to around 27 or 28C during the afternoon.

Unless you’re a very heavy sleeper you couldn’t fail to have been awoken abruptly during the early hours of Friday morning as the humidity finally triggered violent thunderstorms. Across Aylesbury and the surrounding area, between 2am and 3am, lightning lit up the sky roughly every 10 seconds and thunder rumbled constantly. Rainfall estimates suggest around 10-15mm fell locally.

After a quieter spell, more storms rolled up from the south by around 5am, bringing with them torrential rain, frequent lightning and some gusty winds.

However, it wasn’t until around 9am that some of the most severe storms developed, just in time for the morning rush. In nearby Tring, unofficial rainfall recordings showed that 20mm of rain fell in about 30 minutes and hailstones the size of marbles pummelled the town. However, by 10am, the storms had disappeared, the sun had returned and temperatures soared.

After the hottest day of the year so far on Friday with 29C recorded in nearby Chesham, the biggest thunderstorm outbreak of the weekend was predicted to hit Aylesbury on Friday night.

However, they developed a little bit further north near Milton Keynes with Aylesbury and the immediate area largely missing the ‘fun’.

Thunderstorms, however violent, are generally quite small, potentially just a couple of miles across. If you’re underneath one then the weather can be disruptive whilst, just a few miles either side, it remains dry.

Such small features are very difficult to pinpoint in advance.

There may be one or two isolated showers or thunderstorms around during the remainder of this week, including this weekend.

However, the vast majority of the time is looking fine with some hot sunshine. Temperatures will climb to around 25 or 26C although the humidity will be lower than last week.
