Put the covers back on your barbecues, because summer isn't here quite yet.
Approaching thunderstorms are set to disrupt the idyllic weather we have been experiencing this week, bringing temperatures tumbling down by around 10C on Monday.
Parts of Norfolk reached 24C yesterday, although the northern coastline near Cromer was significantly cooler because of a northerly wind in the region, said meteorologist Adam Dury of Weatherquest.
People lost no time in enjoying the balmy weather all over the county yesterday, including at North Norfolk Railway's Poppy Line, where tourists spend the day riding the steam engines.
Today will get off to a misty start on the coast and inland Norfolk should only be slightly cooler at 21-22C. Norwich will be cooler at 18C.
However the Great Yarmouth region will experience a wide range of temperatures.
The town will go from 20C on Friday to 13C on Saturday, before rising to 23C on Sunday.
On Saturday evening there is an increasing risk of thunderstorms throughout the county, with heavy rain showers continuing all through Sunday. Saturday's south-easterly wind will change to south-westerly the following day.
This marks the beginning of a dominantly rainy week, with a risk of showers from Tuesday to Thursday.
Monday should be a dry day but the rain over the weekend will bring the temperature down from 22-23C on Sunday to 14-15C the following day.
Temperature will remain at highs of 15C on Tuesday, before dropping to 13-14C on Wednesday.
However, despite the changing weather, hay fever sufferers will be disappointed to hear that pollen levels will remain high into next week.
The UK-wide Met Office forecast says it will be unsettled, cooler and breezy on Monday and Tuesday, with rain at times.
The Met Office said the highest temperature on Friday was 29.1C in St James Park in London, while the lowest was 3.7C in Eskdalemuir, Scotland.
Meanwhile in Suffolk, Santon Downham enjoyed the hottest day in East Anglia but Writtle, Essex scored the lowest minimum temperature at 6.4C.
