A series of lows will bring the change, but by the weekend it lookslike a
ridge will build from the west and cooler air will be pushed over the UK as
a result.

But ridges generally produce warmer conditions at this time of year...

If the centre of the HP that is ridging is well to the West in the Atlantic
I would think there is a chance of fresher NW'lies.
