UPDATE 19:49 UTC SLGT introduced to parts of the English Channel / Dorset, Wilts etc where a few scattered elevated thunderstorms may occur late on Monday night into Tuesday morning. Uncertainty remains over timing and coverage of any lightning activity, and it is possible isolated pockets of lightning may occur elsewhere over Devon/Cornwall, but the most favoured corridor is essentially Lyme Bay

An upper trough will push near southwestern parts of Britain on Monday and the associated PVA and mid level instability could trigger scattered showers on Monday night into Tuesday morning. 

It should be noted that thunderstorm activity is not expected during the day on Monday, and that the risk of thunderstorms spreading in from the south-southwest are not expected until overnight on Monday and into the early hours of Tuesday (the end of the forecast period). There is the potential for an upgrade to a SLIGHT along the southern part of this region if model consensus improves. 

An update and more detailed discussion will likely follow Monday morning.
