Carntogher (County Londonderry) weather

Headline:

Bright spells and scattered showers today.

Today:

Winds well down from yesterday with Storm Floris now clearing northwards, but fresh west to northwest breezes will keep a run of brighter spells and showers across the area. Heaviest outbreaks expected during the morning before dwindling through the afternoon. Maximum temperature 19 °C.

Tonight:

Most staying dry with clear spells, with winds easing light to bring the risk of isolated rural fog patches in the south come dawn. Minimum temperature 9 °C.

Wednesday:

A fine dry, bright morning. Cloud increasing during the afternoon to bring the chance of some patchy rain to the west for the evening. Southwest breezes. Maximum temperature 20 °C.

Outlook for Thursday to Saturday:

Rain early Thursday, then brightness and isolated showers. Showery Friday with risk afternoon thunderstorms. South mainly dry, bright Saturday, north seeing showers or longer periods of rain.

This period starts with something of a north-south split. Some locally heavy rain or showers, with a risk of thunder, will likely affect the north, along with some strong winds, whilst the south looks like starting mainly dry with some warm sunshine and lighter winds. There is a small chance of some rain or showers even in the south, but more likely it will be mainly dry and warm here. Temperatures will probably be close to average in the north at first. As we move towards the middle of the month, there is an increased chance of high pressure becoming more dominant, leading to drier, more settled conditions becoming more widespread with above average temperatures. However, some brief unsettled spells remain possible, particularly towards the end of this period.

High pressure, and therefore largely settled conditions overall, appears more likely for the second half of August. Although dry weather is likely to dominate, periods of rain or showers and thunderstorms may develop at times, these perhaps more likely later in the period. Above average temperatures overall seem most likely, with the potential for hot spells to develop, especially in the east and south.
