The Met Office has issued a yellow weather warning for Northern Ireland saying whilst many places will be largely dry, thunderstorms with heavy rain and hail are likely to develop in some places over the weekend.
The warning is active for Sunday 11 June, from 12:00pm to 9:00pm.
A spokesperson for the Met Office commented:
"High temperatures on Sunday will trigger a scattering of showers across the warning area, some of which are likely to be torrential and thundery, perhaps bringing a few places 30-40 mm in an hour.
"The odd place, affected by multiple showers, could see more than this, perhaps in excess of 60 mm in a few hours, this being most likely across Wales and central England.
"As well as rain, additional hazards will be hail, strong gusts of wind, and lightning will be additional hazards. Despite this, many places in the warning area will remain dry, or only see small amounts of rain, due to the scattered nature of the heaviest showers."
Temperatures are expected to reach mid 20's over the weekend and into next week.
