Thursday 15th September 2016 – Sunday 18th September 2016

Hi all,

Well, after waiting all summer for a decent storm, one finally arrived nearly two weeks into September and wasn’t it a belter. Torrential rain, continuous lightning and roaring thunder. My kind of heaven but with localised flooding someone’s kind of hell. At Chaddy HQ the storm dropped 16.8mm in an hour. The wettest area around Bramhall saw 30-35mm of rain fall. That’s about half a month’s worth. During the torrential downpour we also managed an impressive rain-rate of 145.8mm/hr. As the storms moved through the region the whole cell produced over 10,500 lightning strikes. So, any more storms to come?

Over 10,500 lightning strikes were recorded

Thursday: I am expecting a cloudy and misty start in some places. This will be slow to burn off especially towards the hills. Eventually it will be a day of sunny spells and again very warm for September and feeling so with lighter winds than Wednesday. Max 24°C.

A widespread storm risk later on Thursday and overnight

Thursday (overnight): From late-evening on Thursday we have a warning in place for more storms. These storms will develop to our south, move north then away to the east. The timing or certainty is very tricky. So be aware of possible thunderstorms in the early hours and don’t be surprised to hear a rumble or two.

Fresher and cooler air arrives from the Atlantic on Friday

Friday: All change. Any morning storms, cloud and rain clearing. A much brighter afternoon with sunny spells and breezy. What will be noticeable will be how much fresher and cooler it will feel as northwesterly winds arrive. Just a chance of a shower later on. Max 17°C.

Saturday: Looking reasonable. Mainly dry with sunny spells. Temperatures around normal. Max 17°C.

Sunday: Bright spells for the morning. Cloud thickening with rain likely to arrive into the afternoon. Max 17°C.

cooler-overnight

After the recent warmth; some chilly nights expected next week

Next Week: Bright spells and some showers by day. A little cool compared to recently and overnight temperatures likely to slip into single-figures.

As always, our weather is ever-changing. Keep up-to-date with what’s in store by following my tweets via @ChadWeather on Twitter.

Thanks,
Jon
