Overnight temperatures fall away rapidly to 9C in rural parts but milder in towns and villages. Cloud will thicken from the west later on signalling a change in the weather.
Thursday sees a band of cloud and patchy rain crawling across the country. It will be mild and rather humid feeling with highs of 22C. This is most likely in the south east which should hold on to the brighter spells.
Friday sees the weak band of rain returning and as it does is likely to turn the rain heavier. It will be cooler too with highs of 16C. That rain is likely to continue through Saturday but a little more showery in nature. Some sunny spells will develop on Sunday, but again there will be showers.
