The Met Office has issued two separate thunderstorm warnings for parts of the country, just a day after the UK recorded its highest temperature of the year so far.
The first yellow warning, in place across the whole of Northern Ireland from midday until 9pm this evening, warns of “some damage” to buildings and some flooding.
The weather service said the heaviest showers are most likely in the east.
A separate thunderstorm warning is in place across parts of southwest Scotland, including Glasgow.
“Heavy showers, some perhaps thundery with a chance of hail in a few spots, are expected to move eastwards across parts of Scotland this evening,” the warning read.
It is in place from 5pm this evening until 11pm.

Though, temperatures are to remain mild in both the affected regions despite the conditions – with Belfast to hit highs of 19C (66F) and Glasgow highs of 16C (60F).
The rest of the UK will be mostly on the cloudy side with outbreaks of rain moving eastwards.
