10 Day Forecast for Snowdon

Page loading ...

Rain to start on Thursday, becoming brighter later.

This Evening and Tonight:

A cloudy night across the region with rain gradually pushing southeastwards as the night goes on with some heavy bursts at times. By the end of the night it will turn dry and clear in the far north and west. Minimum Temperature 13C.

Thursday:

Rain will clear around midday leaving plenty of sunny spells, but scattered showers are also likely. Compared with recent days there will be a fresher feel. Maximum Temperature 20C.

Outlook for Friday to Sunday:

A bright start on Friday but clouding over with patchy rain later. Mainly cloudy on Saturday with a risk of patchy rain, then a risk of heavy rain on Sunday.

Day 6 to 15

Next week is expected to stay breezy across northern and western areas with occasional light rain or drizzle. Bright or sunny spells are more likely across central, southern and eastern areas and it will feel increasingly warm and humid across England and Wales. It may be very warm where there is prolonged sunshine. There will probably be a good deal of dry and bright weather in the south and east over the coming days, with only brief interludes of thicker cloud and rain. As a result, this part of the country may well stay very warm and humid. This pattern is quite likely to continue into the following week, with warm dry weather predominating, especially in the south, and longer spells of rain and wind more likely in the north.

Day 16 to 30

During this period it looks likely that the weather pattern will only change slowly. High pressure will tend to dominate with southern areas probably seeing the driest and brightest weather. Further outbreaks of rain and strong winds may move across the north, and perhaps sink southeastwards at times. Into September, confidence in the forecast decreases. However, we will probably see longer dry and settled spells at times, these perhaps becoming more dominant in the north and northwest. Temperatures by day are likely to be generally warmer than average, but there will an increasing chance of chillier nights.
