It looks like we’re still on course for some lovely weather this weekend thanks to a ridge of high pressure but there is still a question mark about Sunday.
Tonight the odd shower in places otherwise dry with the cloud clearing and turning chilly.
Temperatures typically dropping as low as 3 to 7 Celsius in the towns and cities with some ground frost in the countryside.
A slight air frost is likely inland in rural parts of the north with temperatures just below freezing by dawn.
Some cars may have a frost on the windscreen first thing tomorrow morning.
Otherwise tomorrow promises to be a very nice day - dry and bright with plenty of sunshine.
The sunshine hazy at times with a few cirrus clouds.
Temperatures will recover reaching 13 to 15 Celsius in the afternoon.
The wind mainly light but picking-up on the Pembrokeshire coast, so ideal weather for a trip to the coast tomorrow.
Great weather too for the Big Event in Cwmbran and The Nantmel Show in Powys.
Tomorrow night will be dry and cool. Sunday will start dry with sunshine in the north but rain will spread from the south.
The wind picking-up as well making it feel chilly with highs of only 12 to 15 Celsius.
At the moment, it looks like the heaviest rain will be in southern counties.
The north may stay dry but there is more uncertainty in the forecast than usual.
It all depends on the track of a developing area of low pressure takes as it moves northeast towards northern France and southern Britain.
The autumn equinox is tomorrow and next week the weather will be more autumnal – wet and windy at times.
So my advice is make the most of the fine weather on Saturday and in the north on Sunday if you can.
