Garwnant Visitor Centre (Merthyr Tydfil) weather

Headline:

Rather changeable over the Bank Holiday weekend.

This Evening and Tonight:

It will be a cloudy evening and night with outbreaks of locally heavy showery rain, especially over hills in the southeast. Fog will also affect the high ground. Mild and frost-free, though rather windy with brisk east to southeasterly winds. Minimum temperature 9 °C.

Saturday:

Saturday will start grey with showery rain, locally still heavy. The rain will slowly fizzle out and skies should brighten a little heading into the afternoon. Brisk winds slowly easing. Maximum temperature 14 °C.

Outlook for Sunday to Tuesday:

Easter Sunday looks bright with lighter winds. Isolated light showers possible later. Easter Monday is likely to be a more widely showery day, with sunshine and showers continuing on Tuesday.

Many areas probably starting this period on a rather showery note, with central and southern parts of the UK more likely to see the heaviest and most frequent showers. These will likely be quite slow-moving with the chance of thunder in places. With time, high pressure is expected to become more dominant across the UK, with more prolonged spells of dry weather likely developing, although further rain or showers remain possible at times. Given often light winds and for some, a fair amount of sunshine, it should feel pleasantly warm by day, though areas subject to onshore winds and perhaps also most cloud, especially North Sea coasts, may remain somewhat cooler. Some chilly nights remain likely, especially where skies are clear.

Early May will probably see a good deal of settled weather with high pressure patterns most likely to dominate. There are signs that towards mid May, pressure may fall in the vicinity of the UK, bringing an increased chance of rain or showers. Throughout this period, temperatures are expected to be near to a little above average, though some day to day and regional variability is to be anticipated.
