Coleraine (County Londonderry) weather

Headline:

Heavy rain developing in the west.

Today:

A mainly dry start and rather cloudy with some bright spells. Patchy rain over the west, the rain becoming heavier and more persistent here during the day, perhaps turning thundery at times. Outbreaks of rain spreading east through the afternoon. Maximum temperature 21 °C.

Most of the rain clearing during this evening, the cloud becoming well broken overnight with a few shallow mist and fog patches by dawn. Winds falling light. Minimum temperature 8 °C.

It will be mainly dry and bright with sunny spells and feeling quite warm. The cloud increasing at times with isolated showers. Light winds. Maximum temperature 19 °C.

Outlook for Wednesday to Friday:

Bright or sunny spells with scattered showers on Wednesday and Thursday. Windy with outbreaks of rain on Friday.

Residual rain clearing the southeast, if it hasn't done before this time, with widely fine and much fresher and cooler conditions than of late. Perhaps turning wetter and windier in the northwest though, with more unsettled conditions spreading across the UK through the coming weekend. Not everywhere will see rain or showers, and there will be some brighter, more shower weather too, particularly on Sunday where there is a risk of thunderstorms. Following this, more changeable weather is expected with winds mainly from the west, leading to a typical northwest-southeast split whereby rain and showesr are most frequent in the north and west, whilst south and eastern areas are more often dry, bright and warmer.

Changeable conditions are most likely through the middle part of the month, with showers or longer spells of rain, but also some drier, brighter interludes. Areas towards the northwest are more likely to see the wettest conditions, whereas those towards the southeast stand a greater chance of longer drier periods. However, there is also the chance of occasional thundery outbreaks, which could bring heavy rainfall to any part of the UK. There are hints that more widely drier conditions may develop by the latter part of the month. Overall, temperatures are forecast to be above average, with the greatest chance of very warm or hot spells in the south or southeast.
