Cambridgeshire is in the midst of sub-zero temperatures, snow and ice – and is likely to be until at least the weekend, according to forecasters at the Met Office.
To say it is going to be chilly would be an understatement, with temperatures predicted to creep over zero for only a few hours this week.
It feels like we've been sharing warnings about the Russian Beast from the East for days – but now it is finally arriving in Cambridgeshire and the temperatures are plummeting.
It has prompted the Met Office to extend its weather warnings.
The weather service has now extended its yellow warning for snow from two to four days this week – with a yellow warning now issued for Friday too.
With that in mind, we've pulled together the five day forecast so you have the latest information.
There is a yellow weather warning in place for most of Cambridgeshire from midnight until 11.55pm.
It could start snowing at noon.
There is amber weather warning in place for some western parts of the county like Sawtry, between 4am and 11am – when heavy snowfall is predicted – with as much as 15cm in some places.
A spokeswoman for the Met Office said: "Snow showers or longer periods of snow are expected on Tuesday, accompanied by very low temperatures.
"There is the potential for travel delays on roads, with some stranded vehicles and passengers, as well as delays or cancellations to rail and air travel.
"Some rural communities could become cut off. Power cuts may also occur and other services, such as mobile phones, may be affected."
The yellow weather warning will remain in place all day.
It may snow between noon and 4pm. The temperature will barely get above zero, and will be sub-zero for most of the day.
There is currently no snow forecast for Thursday, although it will remain bitterly cold with temperatures fluctuating between -1C and -3C.
Snow is predicted to start falling at 3am and carry on for much of the day. Temperatures will again remain sub-zero.
A yellow weather warning has now been issued for Cambridge on Friday, and is in place from just past midnight until 6pm Friday evening.
Between 5 to 10cm of snow is expected "quite widely" while long delays and cancellations on bus rail and air travel could occur.
Temperatures will fluctuate between -1C and 1C.
During the weekend, snow across Cambridge and much of the UK should slowly peter out from the south, but snow showers will remain in the far north of the UK.
Across central and southern areas, widespread mist and fog may be slow to clear. It will stay cold or very cold, with temperatures in Cambridge not likely to be reaching more than 1C.
All in all, it's going to be really, really cold. Make sure to wrap up and keep an eye out for elderly neighbours.
