Next week, cold air struggles to come south but we do still end up with
an upper trough/low pressure over UK with a tricky rain/sleet/snow mix.

Wow the stratwarm has gone ballistic at 10hpa.

Zonal wind has also decreased markedly

Going to be an interesting time, one way or the other!

Ciao,

I take it the January cold spell is off the agenda then, for the south
at least, although to me it looks like quite sudden shifts could still
take place which would explain the all round uncertainty It seems that
UKMO are concentrating on February. More jam tomorrow? Shame the frosty
highs couldn't have kept going a bit longer.
