Reason for update
The warning time has been updated to start earlier on Friday and finish earlier on Saturday.
A spell of quite prolonged and often heavy rain is expected to spread northwards into parts of England on Friday though there remains uncertainty in how far northwest this progresses. This area of rain then clears away northeast on Saturday morning. Parts of East Anglia, the East Midlands and southeast England may see 20-40 mm of rain with a few sites potentially seeing 50-70 mm. However, many parts will see much less rainfall. Some thunder and lightning is also possible, particularly in East Anglia, the East Midlands and southeast England but heavy rain is the main hazard.
