I'd be sceptical of it going ahead next week. The best forecast I can find for the week ahead has it nice and cold:
Here is a summary of the NWP output for noon on Monday.
Issued 0543, 29th January 2009
The outlook today is a wintry one. An upper cold pool will move westwards
towards the UK on Monday but there are uncertainties to its exact track and
depth. It's likely there'll be snow, however, especially in southern areas
of the UK. Areas further north are at lesser risk but it all depends on the
track of that cold pool.
During Tuesday the cold pool will stall as trough disruption occurs to the
west. If it stalls over the UK (MetO/GFS), further snow is likely. There's a
moderate risk of milder air coming in to the SE of the UK for a time,
turning any snow back to rain.
For Wednesday onwards, the pattern remains cold. It's likely the winds will
back NE'ly or NNE'ly, drawing in further snow showers for eastern and
northern areas in particular.
