I've just ordered 10 Kg of salt. Not to throw on the path when it starts snowing in London, but to chuck on the model updates every 6 hours. Should keep me going till the 25th.....
Quick question: as in the chart above, could the vortex be split 'too wide' with the North American side sending us endless rain as the energy warms over the Atlantic?
The OPI figure now (-1.89) cannot be the running mean total because it fluctuates so wildly, even around the -1 to -3 regions. Surely some forecast data must have caused it to jump? Weird though, as you say the 12z was a pretty good run!
