OK guys, it's happening. The weather forecast suggests that a huge 'snow bomb' is going to explode all over Britain.
It could possibly have the power to cause chaos on trains, planes, and roads, as well as the potential for power outages across large swathes of the UK.
Oh, and - depending on where you live - you could be looking at temperatures that could be as low as -10C. That's something to look forward to, isn't it?
If you woke up - like many people - to a lovely sunny day this morning, that could be all about to change. The Met Office has already issued several warnings for the next couple of days.
From tomorrow evening, yellow 'be aware' weather warnings come into effect across most of mainland UK. In fact, you have the best chance of avoiding it if you're in the far North East of Scotland.
On Wednesday, anyone in Scotland might get a break, but the warnings remain in place for everyone else on the British mainland.
The worst hit area is likely to be in London and the South East of England (for a change) but snow could be seen in the North and North East of England as early as today.
The South could see around 10cm of snow from around 9pm tomorrow night, continuing into Wednesday.
The Met Office told the Sun: "We are looking at a fairly unsettled week with a mix of rain, snow, sleet and gales.
"There's a potential for disruptive snow in some parts of the country, particularly in the South East area on Tuesday and Wednesday.
"In the South between 1-3cm is likely to accumulate quite widely on the ground, with up to 10cm in hilly areas such as the Chilterns.
"Temperatures will dip this week to as low as -8C tonight in Aberdeen and could sink to -10C in Belfast on Wednesday.
"But the more widely felt temperatures will be at around -2C."
I mean, faced with the alternative, suddenly -2C doesn't sound so bad.
This is all caused by the fact that the prevailing weather front blowing into the United Kingdom at the minute is shoving a load of freezing cold air down from the Arctic. That could mean that if you're travelling anywhere it is going to be more difficult than usual.
If it does materialise, you'd be smart to expect delays and possibly cancellations to trains and flights. If you live in the countryside, you might even experience power cuts, or being cut off by the conditions.
Let's hope it doesn't actually happen, eh?
