Looks like the winds will turn to the NW/NNW for a time with cold upper air running over the Irish sea, normally in these cases showers train across parts of NW/W/SW Wales but can push further inland, the ICON model has been picking up on these the last few days ive noticed, one to keep an eye on.
The low pressure system on Wednesday looks unlikely to impact Wales now, going further south. That being said this mornings GFS does have it clipping the S/SE corner of the UK...
