We have seen some cool nights recently, but the cold will subside over the next few days as an anticyclone moves eastwards towards the middle of the week bringing in slightly warmer conditions from France.
Apart from some rain in the far north-west on Tuesday and Wednesday, a high pressure system gives plenty of dry, fine weather across Britain with light winds. There will be sunny spells and as the winds shift to the southern quarter by Wednesday it will turn warmer as temperatures reach the early to mid 20s Celsius in the east and south. But don’t expect a heat wave, as it is now autumn. And unlike last week, the southerly wind will be largely devoid of tropical storm remnants as the North Atlantic and Caribbean hurricane season remains relatively calm.
Later on Wednesday a cold front approaches Northern Ireland and northwest Scotland bringing cool winds and rain. This front moves slowly south and east across the country on Thursday, although much of the day across much of England and Wales is expected to continue to be nice and warm. Some suggest that the front might weaken or slow down as it progresses, but not all models agree.
Friday likely sees a low pressure regime across Britain as cooler weather tries to move in from the northwest. There are uncertainties as to the timing of this, however, making Friday the hardest to predict. But it’s definitely going to be unstable and eventually cooler.
It could remain choppy with showers especially in the East until Saturday, but as the pressure builds towards the West, the weather should improve again next weekend, but probably with a cold wind North. As a result, overnight grass frosts could return to some vulnerable rural areas, although by Sunday we should see more sunny spells, particularly in the West.
