Chief Forecasters 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
The Met Office have issued a Yellow Warning of Rain
Valid from 16:00 on Tue, 27th Jun 2017 until 09:00 on Wed, 28th Jun 2017
There is an increasing risk of heavy rain, with thunder possible, developing over southern England on Tuesday afternoon before spreading northwards during the evening and overnight. Many places will miss the worst of the rain, but there is a low likelihood of flooding of homes and businesses as well as disruption to transport.
