A Met Office spokesman said the conditions would turn “stormy” in the coming days.
She said the continued low temperatures were due to the “long nature” of the cold spell which is unusual for this type of weather, as they don’t last more than three to five days under normal conditions.
“The air is coming straight from the Arctic, so it’s very cold air,” she said.
“It’s going to stay cold until Friday, and then looking further into the weekend we have some deep low pressure areas pushing in, so a big change in the weather pattern, and we could see some stormy conditions by the end of the week.
“The cold doesn’t really last until the end of the week, but we have a very different type of weather coming in that could affect it.”

As the UK’s Health Security Agency issued an amber cold health alert for the whole of England, emergency weather plans were put in place for homeless people across West Northamptonshire.
The Council enacted their Severe Weather Emergency Protocol (SWEP) and everyone we knew was sleeping outside somewhere warm and dry to stay overnight.
An amber alert means that the impact of the cold weather is likely to be felt across the entire health service for a longer period, and the whole population may be at risk.
