There is a definite media conspiracy here.
Their lazy journalism of jumping on any bandwagon without bothering to check any facts has backfired on them and now they are furiously trying to cover themselves by pretending that all weather that is not average, is actually freak weather and signs of 'climate change' or whatever is the latest buzzword.
Talk of jetstreams may be relevant for an international meteorological conference, but is basically evidence of bull****ting by weather spokesmen when speaking to the public.
The only reason we have warm air from the Med / N. Africa at present is because there is a large high pressure centred over Denmark. If that high had been just to the west of Ireland, which is nothing unusual for high pressures, the northerly winds would have pulled down air from beyond the Arctic Circle and we would be lucky to reach 15C with the sun shining during the day, and northern areas would be getting night frosts and sleet or snow showers.
Both of these scenarios are very possible in early October any year. They are not common admittedly, and are the extremes of what we can expect, but they are certainly not 'freak' weather. They are the result of our island's geographical position.
Unfortunately, two weeks ago the media was full of the "forecast" (they present it as fact with large banner headlines) that we were going to get heavy snow early in October. No one actually investigated where this stuff came from, and anyone can set themselves up as a weather 'expert' and get publicity by feeding endless headline grabbing rubbish to the tabloids.
Now, rather than admit they have been conned by dodgy forecast information and have egg on their faces because the exact opposite weather has occurred, the media are trying to hide behind the idea that the weather is now out of control, which it is not.
