Suffolk’s summer is set to end on a high this week as large parts of the county bask in sunshine.

After several days of rain and falling temperatures, forecasters said the county could expect highs of up to 27C (80.6F) and dry weather on Thursday and Friday.

The upturn is set to extend in to the weekend, but forecasters have warned Bank Holiday Monday could be blighted by thunderstorms as temperatures tumble.

Steve Western, forecaster at Weatherquest, said there was a “30% risk” of thunderstorms hitting the region on Sunday and Monday in a bleaker outlook for the end of the week.

“But before then it will be mostly fine and dry and getting quite warm; even hot again,” he said.

“The average for Suffolk at this time of year is 22C (71.6F) and it will be getting up to 25C (77F) or 26C (78.8F) on Thursday and Friday.

“But unfortunately there is a risk of some thunderstorms for Sunday and Monday.

“They are coming up from France. It may not happen, but there is around a 30% chance of the thunderstorms hitting us.”

He added Tuesday and Wednesday would be partly cloudy with sunny spells as the county braces itself to enjoy the last of the summer sunshine.

Bookies offered 8/1 that August’s hottest temperature would surpass the UK’s hottest August from 2003, when temperatures reached 38.5C (101.3F).

But so far that benchmark remains intact.
