Most of our attention today will be on the development of Storm Doris out over the North Atlantic as she heads towards the UK to bring a stormy Thursday to many parts with heavy rain, hill snow and severe gales gusting up to 80 mph likely to bring some disruption.
At present Doris has barely formed over the Atlantic but during today the wave feature that will become Doris will be sitting on the right hand side of the developing jet stream, becoming diffluent, and as a result this feature deepens pretty rapidly as it transfers across to the left exit area. For all you budding meteorologists out there it is a classic example of a wave development into a potentially notable storm.
in the meantime for today's weather and we start this morning off with a frontal boundary lying west to east across central parts of the UK bringing outbreaks of rain with it. To the south it is mild and cloudy whilst to the north it is colder but brighter with sunny spells and scattered showers. That frontal system continues to slowly sink south today taking the rain with it but will never make it to southern counties of England before it starts to push back northwards later on with rain becoming heavy and persistent over Northern Ireland by this evening. So the far south remains mild but mostly overcast again today with temperatures into double figures whilst much of northern Britain is chilly with sunny spells and scattered showers, these mainly in the north and west.
A very wet night follows for Northern Ireland, northern England and southern parts of Scotland as Storm Doris moves in with heavy rain turning to snow over higher ground in Scotland later in the night. It will become increasingly windy in the south but the rain here will tend to ease whilst for northern Scotland a quiet and clear night will lead to some frost forming. Then for tomorrow it's all about Storm Doris - we'll have more on her throughout the day.
