Fan Brycheiniog (Powys) weather

Headline:

Feeling fresher and turning brighter.

This Evening and Tonight:

A mostly dry evening and night is expected across the country. It will be fairly cloudy at first, with a little drizzle over the hills. Clearer spells then developing towards morning. Remaining fairly warm, with light winds, but feeling fresher. Minimum temperature 11 °C.

Wednesday:

Wednesday looks set to be a largely dry day with a fair amount of sunshine. Perhaps an isolated light shower developing, mainly in the west. Feeling pleasantly warm, but fresher. Maximum temperature 22 °C.

Outlook for Thursday to Saturday:

A ridge of high pressure will give a mostly settled day on Thursday, with sunny spells. Gradually clouding over on Friday with damp and breezy conditions spreading east for Saturday.

Cloud and rain associated with an Atlantic frontal system and area of low pressure is likely to sweep south and east, with rain always most persistent on western hills, especially western Scotland where large rainfall totals may have built up by this time. Eastern areas in shelter could see warm and humid brighter breaks, but with a risk of thundery showers, which could be slow moving at first. Likely turning cooler and more showery into next week, followed by a changeable pattern with further areas of cloud and rain and brighter, more settled spells in-between. Temperatures are likely to be around average overall, with an increasing chance of warmth in the south as the period progresses.

Changeable conditions with a predominantly northwest to southeast split in temperature and rainfall, and the potential for further occasional episodes of hot weather and thundery outbreaks, are considered likely to gradually give way to something more settled and dry overall through the second half of July. Temperatures are likely to be above average, with the greatest chance of very warm or hot spells in the south or southeast.
