The heat and dry weather persist for many, we have this great area of high pressure sitting across Germany, to Denmark and to Austria.
“Lots of dry weather but there is low pressure which brings a lot of showers.
“Heavy showers and thunderstorms affecting northern Portugal and Spain, France and into the UK.

The UK has so far not seen its hottest day of the year, although forecasters “are reluctant” to rule out the possibility later.
Temperatures in Santon Downham, Suffolk, peaked at 28.2 ° C (82.76 ° F) just before 1 p.m. on Wednesday, the Met Office said.
But it’s just below the 29.7 ° C (85.46 ° F) recorded in Teddington, Middlesex on Monday, which has been the hottest day of the year so far.
It precedes thunderstorms that are expected to spread across much of England, including London and the South East, from 6 p.m.
“The higher clouds hanging over parts of the country will make it difficult, as they block the sun and keep it from getting hotter, but we’ll see, there is definitely potential.”
However, Mr Partridge has warned that thunderstorms are starting to form and develop across the English Channel and will reach southern parts of the UK around 7pm.
He said: “This will bring heavy rain, loud thunder and frequent lightning for much of England and South Wales until around midnight.
“The rain will be quite heavy with up to 30mm falling in a fairly short period of time.
“It will be a horrible night for many, especially when trying to sleep, staying quite hot and humid in London and the South East around 17-18C, combined with the humid weather.”
