Southeast and eastern England will be drier with sunny spells but a few isolated showers are possible. On Sunday, a new frontal system will move across from the northwest, bringing rain to all areas. Monday should be largely dry with just the odd isolated shower as a ridge of high pressure topples across the UK. However, this will be a rather weak feature, and a new frontal system will move towards Scotland and Northern Ireland, bringing rain during the evening with some sleet or snow for the Highlands. Overnight, rain will also spread across Wales and England, although it might not quite reach eastern and southernmost England.
This is about a 30 percent chance and has some support from similar setups in the past. One model pushes the expected high pressure centre farther north, which would induce colder north to north-easterly wind flows and bring a risk of wintry showers, mainly to northern and eastern areas but this looks to be a low risk at the moment. More likely, colder air will stay away to the east.
The Met Office also predicted chilly temperatures to grip the nation.
The forecast between Tuesday, March 16 and Thursday, March 25, said: At the start of this period, the weather is likely to begin settling down with high pressure building from the southwest.
Charts assessing wind speed by WXCharts show the UK turn purple at 3pm this afternoon, as the UK braces for stormy conditions.
Weather maps by forecasters Magicseaweed, also show a terrifying weather system moving towards the UK around 6pm tonight.
The chart, which represents the scale of the swell, shows a mass of red and pink approaching the west of the UK.
The map suggests the huge swell could see waves reach a height of 40ft (12metres).
The chart shows the potentially damaging conditions hit the UK at midnight tonight and will have fully dispersed by 3pm on Friday.

Met Office warnings for wind are in place across Wednesday and Thursday, with up to 70mph gales expected to hit some areas of the UK. This is due to an Atlantic system, bringing the strong winds and blustery showers to England and Wales by midweek.
Temperatures generally stay a little below the average and nighttime frosts are possible.
BBC Weather s long-range forecast between Sunday, March 6 and Sunday, March 16, warned of low pressure systems from the Atlantic sweeping in by the middle of the week.
The forecast said: We will see the weather pattern change as high pressure declines over Northwest Europe. This will shift away to the west in the Atlantic allowing low pressure systems to move in by Tuesday.
