1. Zonal and mild (poss cold zonal at first) 50%
2. Cold and blocked very cold easterly 20%
3. Uncertain, possibly no-mans land, neither fully blocked nor fully zonal 30%
Of course non of the above takes into account solar factors :-)
Safest bet would be number 1!
It's been that way for much of the last 10 winters why should this one
be any different?
Still we've already had a few cms of the white stuff so musn't grumble
