In the blink of an eye the summer weather was swept away as thunderstorms battered East Anglia.
The east had been sweltering in temperatures which had been nudging 30C for much of the week .
But the weather suddenly turned yesterday morning, bringing temperatures down by 10C and nearly 80mm of rain falling in some places.
The highest volume of water fell at the University of East Anglia (UEA) where an unofficial weather gauge measured 80mm of water in just one day.
The average rainfall for the whole of September is 58mm and James Wilby, of Weatherquest, said the levels were quite exceptional.
'It was pretty impressive by any stretch of the imagination as it was well over the monthly average for September in just one day,' he said.
'Meteorologists don't get excited by very much but this was quite exceptional.'
Santon Downham saw water levels exceeding 50mm, with most of the region experiencing rainfall between 15mm and 20mm.
Wymondham was one of the worst affected places with one person having to be rescued by the fire service after his car got caught in flood water under the bridge on Station Road. Police closed the road for a number of hours as pumps worked to clear the water and there was some anger from town residents about the flooding after improvements were made to the road to stop it happening.
A Norfolk County Council spokesman said of the flooding: 'The recently completed drainage scheme has significantly relieved the historic flooding problems at the site.
'However, as this is a piped system draining a large catchment, its effectiveness depends on the water level in the River Tiffey into which it discharges.
'Following the very intense rainfall yesterday, high water levels in the river inundated the outfall, meaning floodwater could not escape.'
Joe Mooney, mayor of Wymondham, said he would be asking the county council to carry out a review of the draining system to see if anything else can be done.
Neighbouring Attleborough also experienced large levels of flooding on Station Road, there was flooding on the streets of Cromer and Thetford and train services between Norwich and Cambridge were disrupted for much of the day after lightning struck the signalling system at Brandon.
Family washed out of home for second time
A devastated family forced to flee their home following a freak flood in the summer have been hit by another deluge – just days before they planned to move back in.
Gary Deere believed he was the victim of a cruel joke when he was first alerted to the latest damage to his property in Cromwell Road, Cromer, yesterday.
However, he revealed the devastation caused by the torrential rain, which was triggered by a thunderstorm, could cost upwards of £60,000 to repair.
Speaking outside his home, Mr Deere said: 'We've been [out of the property] three months now and we're going to have to start again.
'The insurance company, Aviva, have been fantastic but when we come to insure next time what's going to happen then?'
Weekend forecast
Today there will be a vast improvement in the weather with showers expected to clear by the end of the morning.
It will feel slightly breezy but by the afternoon there will be patches of dry and sunny spells with highs of 20C, the average for this time of year.
Temperatures overnight will fall to lows of 16C which will make it feel much more comfortable for those hoping of a good night's sleep.
Once any early mist or fog patches have cleared, much of the region will be dry for a time on Sunday with some sunshine and it will feel slightly brighter in the east of the region with highs of 21C.
However, outbreaks of rain are expected to fall in some areas in the afternoon but there will be nowhere near the levels which fell yesterday.
Temperatures will dip to 14C overnight with the beginning of next week looking dry and fresher.
But the scorching temperatures the region saw last week will likely be the warmest temperatures we see until May next year as autumnal weather draws in.
