The band of rain will edge east on Tuesday. As the temperature and humidity rises in England there is the likelihood of torrential thundery downpours by evening and the threat of flooding.
The heavy rain will edge east overnight with further downpours in eastern England and especially eastern Scotland on Wednesday.
Fresher air will push across all areas from the west by the end of Wednesday and push the heavy rain into the North Sea.
The rest of the week and the weekend sees temperatures falling to nearer normal with a southwesterly airflow bringing sunshine and showers.
There is the possibility that heavy rain in the North Sea could brush eastern coastal areas by the end of the week, then there is a signal for higher pressure in the south for a while over the weekend
