The GFS, whilst not woeful, is a bad run. Especially for this time of year, with the 5C isotherm avoiding our shores at all costs, visiting for only brief periods. This is somewhat of an annoyance especially for June, typically the best summer month.
Whilst it is a bad run, it's going against the UKMO, the ECM and some minor models with it shoving the entire pattern too far eastwards. Not only this, but it's out on its own completely against the Met Office text forecasts.
How reliable is the new higher res GFS? Well we've seen the old GFS disprove everything else in the past, so there's every reason to say the new one should do it even better.
This is more of a disappointment post, but it's based around facts. I think if the ECM runs later and shoves the brief spell of warmth on Thursday and Friday eastwards, it's really a case of looking AGAIN further on down the line for a possible reload scenario. Everything's gone wrong. 30C+ two days ago, to 13C for some under the influence of lower pressure from the north. This is something the Met Office did NOT suggest in their text forecasts, they in fact said quite the opposite with high pressure to our North East giving better conditions in the north. They've quickly backed down from this now, typically.
So what do I see? A typical UK spell, one day of sunshine, temperatures rather good, feeling fantastic in the sunshine. Then overcast and damp the next day, no breakdown in the form of an electrial storm, followed by a usual regime of sunshine and showers for the rest of June.
People looking for a settled spell lasting more than 5 days, myself included need to remember where we live, and that here, in the worlds worst climate, if it can go wrong. It will.
