Most parts of Wales have had more rain in the last few days than throughout the whole of September!
At RAF Valley on Anglesey over 66mm (2.5inches) has fallen so far this month. More than half the October average of 102mm for this location. In September only 8.2mm was recorded.
The reason for the change in the weather is as usual down to the jet stream. Like a roller coaster, the big dipper has moved further south leaving the UK in a trough of low pressure.
The changeable, unsettled weather will continue for the rest of this week with showers or even longer spells of rain. The showers will be heavy at times with a risk of hail and thunder.
It will also be windy at times but with drier, brighter interludes and a few sunny spells as well. Temperatures will be near or a little below average and it will feel chilly in the wind and rain and when the showers come along.
So it looks like autumn has finally arrived and it’s time to dig out the jackets and jumpers!
