The autumn equinox is this Saturday, the nights are drawing in and there is already a noticeable chill in the air.
On Tuesday night the temperature in Pembrey in Carmarthenshire and Tirabad in Powys fell to 4 Celsius, 38 Fahrenheit.
We’ve enjoyed some blue sky and sunshine recently but it hasn’t been dry everywhere with cumulus clouds and a few sharp showers as well.
Today is much cloudier with rain in the north and north-west for a time.
Mid Wales and the south should be drier, apart from a shower or two, and a few bright or sunny intervals are likely as well.
On Friday a cold front and rain in the north will spread into Mid Wales and the west. Southern counties and the south-east should stay dry for most of the day.
As for the weekend, Saturday should be dry with some sunshine and chilly first thing with ground frost in the countryside.
Sunday, though, is not so clear cut. There is a risk of rain but we could get away with a dry day.
There is a lot of uncertainty as to what will happen on Sunday so it would be worth keeping a close eye on the forecast.
Tropical storm Nadine is slow moving near the Azores at the moment in the form of a deep low. More on that in my next blog.
September has been drier than average so far but the signs are it will turn very unsettled next week with showers or longer spells of rain, heavy at times, and strong to gale force winds.
