Temperatures are set to dip well below freezing in Huddersfield later this week.
And the town is also likely to experience problems with black ice, ice and snow over the next few days.
Huddersfield weatherman Paul Stevens said we are unlikely to suffer as much as some parts of Britain, where the mercury is expected to drop to minus 10°C. But it is likely that by the weekend, temperatures in some areas of the town could be as low as minus 3°C.
The Met Office has issued a Level 2 cold weather alert across Yorkshire.
And health chiefs are reminding people to look out for vulnerable neighbours, family and friends and take care when out and about.

A Level 2 alert means that within the next 48 hours, there is a 60% chance of severe weather, with average temperatures only at 2C or below. There is also the possibility of wintry showers, overnight frost and a chance of icy patches.
Dr Mike Gent, Deputy Director for Health Protection, PHE Yorkshire and the Humber, said: “It’s very important to remember that cold does kill, even in places where the temperatures aren’t at their lowest. Most of our advice on keeping warm in cold weather may seem like common sense, but it’s important to remind people how cold can affect them.”
Mr Stevens said “It is going to turn a lot colder, more noticeably after the very mild weather of December.
“Today and tomorrow we will see temperatures struggle to get above 3°C. As we head through the week the clouds move away and temperatures through the night will drop considerably.

“We will also see showers start to come in on Wednesday, bringing sleet and snow, and by Thursday there could well be a couple of centimetres of snow in many areas of the town.
“Coupled with the freezing temperatures, it could make the commute very difficult.
“There will be more wintry showers through the week and, by the weekend, the temperature will have gone below freezing.”
