Upper trough over the Atlantic will slowly advance towards the British Isles, while a slow-moving front will continue to drift northeastwards across England, Wales and Northern Ireland. The post-frontal environment will be characterised by steepening lapse rates as the mid/upper levels continue to cool, with a few showers likely tonight - a low chance of a few isolated lightning strikes, this most likely over SW Ireland where showers will tend to be more widespread.
