Weather: Castlederg hits 25.9C as Norther Ireland sizzles
Northern Ireland's mini-heatwave brought the hottest day of the year so far yesterday as temperatures hit over 25C in some parts of the country.
Much of the province basked in sunshine, with the mercury hitting 25.9C in Castlederg, Co Tyrone.
Elsewhere in the UK, it reached 30C in London's Kew Gardens and St James's Park, 28.7C in Cardiff, and 24.8C in Edinburgh. UK thermometers are expected to climb to 34C today.
In Northern Ireland, the maximum temperature is expected to be 27C.
The Met Office said Northern Ireland would be hot and sunny today - but warned of a risk of thunderstorms by evening.
Early mist and fog patches will burn back towards the east coast, forecasters predicted.
Otherwise it will be dry with sunny spells this morning and will become very warm. Thundery showers will develop later in the afternoon and evening.
Pollen levels will be high over the UK for the next few days, causing misery for hay fever sufferers.
