Oh dear, Mr Slant, your poor children! 
gttia - you could well be in luck this time.
I think although the cold starts from Thursday, snow is more likely from next Sunday onwards so as that's a week away, it's important to keep tuned to forecasts for more detailed forecasts over the next few days.
Latest update from the metoffice reflects what a lot of the charts are showing...
UK Outlook for Friday 23 Feb 2018 to Sunday 4 Mar 2018:
Dry with sunny spells as we head into next weekend with overnight frosts, along with patchy mist and freezing fog. However, outbreaks of rain or drizzle along with some hill snow and stronger winds are possible at times across northwestern areas. Temperatures will turn colder for most with wind from the east or northeast, possibly brisk in SE England. The cold weather will be mainly dry initially with a chance of snow flurries in the east and southeast. Heading into the following week, there is an increased chance of snow for many, especially in the south and east. Although the location and timing of any snowfall remains uncertain. However, some milder unsettled weather may still occur at times, especially in the west.
UK Outlook for Monday 5 Mar 2018 to Monday 19 Mar 2018:
At the start of this period it is likely to stay cold for most with widespread overnight frost. There will be a greater chance than usual of mainly easterly winds originating from continental Europe, which could bring very cold weather at times and the potential for some snowfall, especially in eastern and southern parts. Unusually, it will probably be driest in the northwest. As we head further into mid March there are indications that it may become more changeable and less cold, with the wettest weather and mildest temperatures likely to be in the south or the southwest of the UK, but this is currently very uncertain.
