Jet Stream Changes Bringing In Much Colder Weather
By Paul Homewood
Back on 29th December, I ran the animation of the forecast jet stream from netweather.tv. These showed the jet stream, moving much further south from the end of December position, that had persistently brought strong winds and a mild, moist airflow up from the south west. It was this pattern that had brought so much rainfall to the north west of the country.
The forecast position as at 8th January (above) has proved remarkably accurate, compared with the current situation:
The only real difference is that the flow has not moved quite as far south as predicted. Nevertheless, the country is in a much colder, showery airflow, except for the north east of Scotland, which has borne the brunt of the rainfall.
The correlation of jet stream with the low pressure systems parked to the west of the UK is clear.
The forecast is for the kink in the jet stream to wiggle its way east, bringing much colder air down from the north next week. By next Friday, we look to be in for some very cold and windy weather!
I expect the Met Office will blame it on El Nino, and tell us they warned about it all the time. Mere mortals will probably say it is just weather!
