WINTER jackets will not be relegated to the store cupboard yet as a cold blast of air moves in from the Arctic.
Colder temperatures, wind and rain are set to come to the Portsmouth area for the next week or so.
The unusually warm April will give way to an unsettled start to May as a mass of cold maritime air – called a polar plume – moves south from Greenland.
While the north of the UK could see snow and hail, the south coast will see temperatures struggling to get above 11C and blustery showers.
Night temperatures will average around 5C.
The Met Office said it would be a shock to the system after the warm weather of late.
Forecaster Nicola Maxey said: ‘People will notice the difference because of the nice period of warm settled weather we have seen.
‘It’s a marked contrast. It’s certainly looking unsettled for the rest of the week and is looking to stay that way for the start of May.
‘Portsmouth has a high chance to seeing some showery rain today and on Wednesday and Thursday of this week.’
But she said there was still a chance of the sun breaking through. Ms Maxey added that the historic average temperature for April was around 11C.
