10 Day Forecast for bwlch

Page loading ...

Mostly dry, cold and bright to end the week.

Today:

A cold and frosty start, but a fine day in prospect with long spells of sunshine, especially in the east. Cloud will thicken across west Wales where it will begin to turn breezy. Elsewhere, light winds but feeling cold. Maximum Temperature 5C.

Tonight:

Quickly turning cold for a time in eastern Wales with a frost developing. Otherwise, becoming cloudier and windier with sporadic outbreaks of rain arriving for most through the night. Minimum Temperature -1C.

Saturday:

Rain soon turning heavy and persistent with gales, especially around coasts and hills. Feeling cold, emphasised by the strong winds. Maximum Temperature 7C.

Outlook for Sunday to Tuesday:

Less cold on Sunday with sunshine and showers, especially later. Risk of ice early on Monday, otherwise mainly dry. Turning windy on Tuesday with rain, perhaps becoming persistent.

Day 6 to 15

Tuesday will see some unsettled and windy weather with coastal gales, cloud, and outbreaks of rain and drizzle moving eastwards across the UK. The rain and drizzle will be followed by sunny spells and scattered, blustery showers. Showers will fall as snow over northern higher ground. As we head through the remainder of the week and into the Christmas week it will probably stay unsettled, with further spells of wind and rain, these interspersed by some brighter and showery weather. Temperatures on the whole look likely to be a little milder than average. However, in the period after Christmas Day there is an increased likelihood that milder spells will become short-lived and a colder and more showery northerly or northwesterly regime could become established across the UK.

Day 16 to 30

The most likely scenario for the end of December is for periodically unsettled Atlantic weather to move across the UK from the west. However, there is an increased likelihood that the milder, Atlantic weather will become short-lived and a colder and more showery northerly or northwesterly regime will become established across the UK. Through the first half of January, there is an increasing likelihood of a return to colder than average conditions with an increase in the likelihood of overnight frost and fog, as well as some snow.
