Just after 10.15 on Friday, when the maximum of 12.4C was reached, the wind began to veer into the north with the thermometer dropping 2C rapidly and then falling consistenty until this morning.This heralded the arrival of the Arctic Maritime Airmass having originated from the Arctic and travelled over a considerable expanse of sea before arriving in the UK, which has modified the extremely cold air mass.
Just after dawn today the minimum of 5.0C was recorded with the first recordable windchill this month so that it felt more like 4C.
The cloud is extensive this morning but there were early glimpses of the sun around 8am.
Update at 12.00: Temperature 6.5C but wind chill makes it feel like 3C
