10 Day Forecast for bwlch

Page loading ...

A wet day with strengthening winds.

Today:

A wet start to the day with outbreaks of locally heavy rain. Southwesterly winds will strengthen from the south, with rain turning more persistent, although some drier interludes are possible across southeast Wales. Despite this, it will feel warm. Maximum Temperature 19C.

Tonight:

Heavy rain and potentially very strong winds will continue overnight, before clearing eastwards through the early hours. Turning colder later with scattered heavy and blustery showers. Minimum Temperature 8C.

Friday:

Sunshine and scattered showers on Friday, these locally heavy with the risk of hail and thunder. Remaining windy and feeling cooler. Maximum Temperature 16C.

Outlook for Saturday to Monday:

Generally dry on Saturday, perhaps with some rain in the south, particularly later. Sunday uncertain, but possibly wet and very windy. Mostly dry and sunny through Monday. Rather cool.

Day 6 to 15

For most of the UK it looks like the weather should remain largely settled through the rest of September. Most places will have long sunny periods and generally light winds. However, some mist and fog patches will form during the nights. The far north and northwest will most likely turn a little more changeable through next week with some rain and strong winds. Weakening bands of rain are expected to push southeastwards across the UK but they will become increasingly patchy as they go. Days will be warm for many, at least at first, but nights will be chilly with some localised frost. Into the start of October many parts are set to remain mostly settled, though some wet and windy weather is possible further north.

Day 16 to 30

Settled conditions are expected to dominate across much of the UK through the beginning of this period, especially in the south. There should be a good deal of dry and bright weather with any brief wet and windy spells likely to be confined to the north of the UK. Increasingly long nights nights will lead to a greater risk of patches of fog forming overnight and some places may also see some frost. Despite chilly nights, any sunshine by day will give a rather warm feel. Later on in this period there is considerable uncertainty in the forecast with a chance that some more unsettled weather may become established again.

Day 1

Some drier intervals likely at first, before blustery showers move in on the strong winds through the morning. These perhaps with the odd rumble of thunder and burst of hail. This will lead to a very changeable day on the hills, with sudden reductions in visibility likely, alternating with brighter, occasionally sunny spells. Despite some sunshine, it will be feeling noticeably colder than recent days.

Ice Above the summits
Visibility Improving by dawn, with very good visibility likely outside of showers, and some distant hills visible. However this will rapidly deteriorate to become poor in any showers, especially as cloud descends onto the tops.
Wind Westerly 35mph with gusts 50mph, gradually easing to 20mph with gusts 30mph.
Temp Plus 6C (at high level)
Day 2

A largely cloudy day with some brighter intervals, but also the risk of rain at times. Remaining chilly, especially at height, although freezing levels remaining above the summits. Winds will be noticeably lighter than recent days.

Day 3

Significant uncertainty, although current signal is for an area of rain to move across the Brecon Beacons Strong winds are possible, but this depends on the track of the rain.

Day 4

Mostly dry with sunny spells, but a few scattered showers are possible at first. Any strong winds easing.
