There's considerable support from the Met Office:

"UK Outlook for Thursday 21 Mar 2013 to Saturday 30 Mar 2013:Many areas
fine on Thursday, though a few snow showers possible to the northeast.
Turning much more unsettled towards the southwest later Thursday, with
cloudy, wet and windy conditions then spreading slowly northeastwards on
Friday into central parts of the UK, whilst turning increasingly to
snow. These conditions continue northwards through the weekend, risk
then of significant snow over central and northern areas, though the far
northeast may remain brighter, with just occasional snow showers.
Generally cold with overnight frost, though temperatures perhaps
returning nearer normal in the south."

OK, they don't actually use the "b" word, but the set-up suggests that
any snow in northern parts next weekend would be accompanied by a strong
easterly or north-easterly.
