THE blast of hot air from the continent could bring thundery showers to the North East, according to the Met Office.
Temperatures are soaring and could peak at 29C on Wednesday, when the downpours could arrive.
A Met Office spokesman said: “Isolated heavy, and possibly severe thunderstorms are expected to develop late Wednesday afternoon across parts of Northern England and Southern Scotland.
“Some torrential downpours are possible leading to localised surface water flooding, with hail and frequent lightning also possible hazards.
“The public should be aware that there is a chance of some very localised significant disruption.
“By Wednesday, a hot and increasingly humid airmass is expected to be in situ across much of the UK.
“This airmass looks conducive to isolated thunderstorm development during the afternoon and into the evening.”
