Chief Forecaster's assessment

There is much uncertainty with the forecast for this period and some places could even stay dry. However, heavy and thundery rain could produce 20 to 30 mm rain in an hour and very locally 40 to 60 mm in 6 to 12 hours. Should this occur then some flooding is possible, especially across urban areas. Overnight rain should gradually start to ease and by early Wednesday morning may be confined to parts of the East Midlands and East Anglia
