Looking at just a single weather model output and stating as fact that this will be the outcome in 10 days' time is highly misleading. Certain "tabloid" publishers in the UK (you know who I mean) will week after week will try to tell you that the worst snowmaggeddon in centuries is about to happen in your neighbourhood. In reality, even forecasts 2-3 days ahead can be wildly wrong. If the "ensemble" of weather models run on supercomputers which provide their outputs every few hours tend to agree on a scenario, then forecasters will be confident. If the ensembles disagree, then there will be low confidence. So with all this in mind, the current model runs for the UK are showing some fairly wild disagreements on air pressure in the next two weeks, although a wet and windy regime is more likely than not. ECMWF (the European model) is predicting a deep low pressure area crossing the UK on around 13 Dec. The other models do not predict it, so it's very unlikely to occur. The same model run tomorrow may not predict it at all. Whatever happens, it looks pretty impressive on the chart! #weather #ecmwf #g7izu
