Northerly winds are currently blowing across the UK bringing cold Arctic air across our shores.
This is holding daytime temperatures several degrees below the seasonal norm with some late-season frosts at night.
This chilly air will stay with us during Wednesday, Thursday and Friday with daytime highs around 9-14C (48-57F), sunny spells and blustery showers, and the ongoing risk of overnight frost.
The cold air is heading our way thanks to a combination of high pressure in the Atlantic and areas of low pressure moving to the north and east of the UK – driving northerly winds.
But over the weekend that pattern will – slowly but surely – start to shift.
Westerly winds will develop and by Sunday temperatures should be back to the mid-May average of 12-18C (54-64F).
