Cardiff (Cardiff) weather

Headline:

Warm sunny spells with heavy thundery downpours overnight.

Today:

Any early mist and fog soon clearing, to leave a dry day with plenty of warm spells of strong sunshine. Cloud gradually building from the southwest later into the evening. Maximum temperature 27 °C.

Tonight:

A dry start to the evening with heavy showers arriving into the night. These merging into longer spells of heavy and thundery rain with a strengthening breeze. Warm and humid. Minimum temperature 14 °C.

Thursday:

Heavy rain clearing northwards through the morning followed my occasional sunny spells and heavy, thundery showers. Staying warm and humid. Breezy. Maximum temperature 24 °C.

Outlook for Friday to Sunday:

Further heavy showers and thunderstorms on Friday, accompanied by hail and gusty winds. Warm and humid on Friday, but fresher into the weekend with drier and brighter interludes.

On Sunday, rain and showers will be slow to clear across the north, especially across Scotland and Northern Ireland. Further south, high pressure to the southwest of the UK will extend northeastwards, bringing settled and fair weather mainly across England and Wales. Cloud and rain may hold on for longer across western Scotland and Northern Ireland, while the weather should turn drier and brighter across eastern Scotland where sheltered by high ground. From mid week, high pressure is signalled to dominate much of the UK, bringing dry and fine weather, and feeling warm in the sunshine with light winds for most. Any early morning mist or fog will be quick to clear, and daytime temperature will likely trend around or above normal for the time of year.

High pressure may still be largely dominant at first, maintaining mainly dry and warm weather, with variable cloud amounts. The weather during late June and early July may turn more changeable, with spells of rain or showers probable for all parts at times, and could be heavy and thundery, which is normal at this time of year. Temperatures are likely to be a little above average overall, with brief hot spells possible, these perhaps more likely early in the period.
