Can anyone explain why the GFS charts for precip seem to be struggling with the location, so many conflicting forecasts, and I am not one to moan, in fact I rarely post unless I completely fail to understand a certain point.
The precip (falling as snow) is basically over London/Kent and East Anglia on the current 18z runs I just looked at, and puts everywhere else in a Sleet/Rain scenario.
I am unsure what to trust, and I understand that crucially it comes down to now casting as forecasts can never be 100% accurate, just a bit stumped as some places currently show Heavy Snow for here, and others show Rain, I guess it all depends on the models they're using to generate the forecast, but it's a huge variation so far.
