Parts of the UK also suffered thunderstorms on Sunday night.
A statement issued yesterday said: “Although the locations affected by thunderstorms remains uncertain, a few places may experience a combination of heavy rain, frequent lightning and hail during Sunday night”.
“Should thunderstorms develop, they are likely to move north from the south coast during Sunday evening into parts of south Wales, southern England and East Anglia overnight before gradually weakening during Monday morning.”
The storms are expected to fizzle out overnight, making way for a dry and mild night for most places although southern areas could see some foggy patches.
Things are expected to definitely take a turn for the better on Tuesday with the Met Office predicting it will be the warmest day of the year so far.
South-east England and East Anglia will see the best of the weather with temperatures possibly hitting 28C, way higher than the currently high this year of 23.6C.
Most areas will see a hot, dry, sunny day and temperatures in Scotland could reach 20C.
Only the western fringes of Wales, Scotland and England will see cooler temperatures and possibly some heavy showers at times.
Temperatures are expected to cool as the working week continues although there will still be bright sunshine.
In south-east England and East Anglia are expected to see temperatures around the mid-to-low twenties.
More thunderstorms could also be on their way although these will mainly be overnight.
