A noticeable increase in cloud cover across much of the UK compared to recent days

Saturday will bring a noticeable increase in cloud cover across much of the UK compared to recent days, though parts of the south and southwest will enjoy the best of the sunshine. Scattered showers are expected, particularly in western areas, with Northern Ireland likely to see more persistent

turning to snow on the higher tops, while there is a chance of some dry spells developing in the south. More widespread rain this evening, likely to turn to snow above 400m. Chance of cloud-free hill tops above 600m: generally 10%, except 60% at first and perhaps this afternoon across southern areas. Low

of maritime and continental influences; the air is likely to be warm and predominantly dry, generating fair weather clouds but also some lower cloud bases in moister air to the west. The presence of an upper cold front to the east of England complicates the picture somewhat and will need investigating. What

Its primary uses are for the modelling of clouds and atmospheric flows. The results of these simulations help us to develop the physics parametrizations in the Unified Model. LEM use and collaboration A number of process studies have been carried out using the LEM, including those within the GASS

Today, the Northern Isles and far north of mainland Scotland will see persistent cloud and outbreaks of rain, heavy at times, gradually easing later in the day. Elsewhere across northern Britain, expect variable cloud cover with scattered showers, particularly frequent and heavy in northwestern

and Wales. However, the main story for tonight is not the space weather, but the terrestrial weather. Most areas across the UK are expected to experience significant cloud cover, which will severely limit the chances of seeing the aurora. Even in regions where geomagnetic activity is strong enough

Mid-May brings mostly dry, settled UK weather, but slight changes in temperature and cloud cover will influence how each day feels across the country.

As we move through the middle of May, the UK continues to experience largely dry and settled weather, though subtle shifts in temperature and cloud cover will shape the feel of the days ahead.  Wednesday will bring a mix of sunshine and isolated showers, with most areas staying dry. The only

across parts of northwest Scotland and possibly the north of Northern Ireland, where it will remain breezy. Elsewhere, light winds and variable cloud cover may bring the odd light shower, but these will be isolated. 🌡️ Heat is building across the UK this week, temperatures could reach 32-33°C

% of average. 1st to 7th Central and northern parts saw mist, fog and frost on the 1st, the fog slow to clear in some spots, especially in the east, but southern and north-western counties became sunny. The north-west began the 2nd clear and frosty, but low cloud, mist and fog affected most other places
