A similar setup to previous days, as pulses of showery rain spread slowly N / NW-wards across southern Britain and southern / western Ireland on the forward side of a negatively-tilted upper trough. A few isolated lightning strikes may be possible, mainly over the English Channel on Thursday night - but most areas will remain void of any lightning. Of greater concern is probably the risk of some localised flooding where heavy bursts of rain become prolonged at times, more especially over S / SE Ireland.
