Chance of precipitation represents how likely it is that rain (or other types of precipitation, such as sleet, snow, hail and drizzle) will fall from the sky at a certain time.
This number shows the air temperature for the time period. You can see the temperature in Celsius or Fahrenheit by using the dropdown menu.
Feels like temperature considers other factors, such as wind speed and humidity. This gives you a better idea of how the temperature will actually feel at the time.
Wind gust shows the highest wind speed that you should encounter at that time, as winds peak and lull.
Strong winds are shown in bold for speeds of 29 mph or more.
The arrow shows the direction the wind is blowing. The letters show the direction the wind is blowing from (on a standard 16-point compass).
The number represents the average wind speed expected at that time.
Visibility measures the distance at which an object can be clearly seen.
| VP (Very Poor) | Less than 1 km |
| P (Poor) | 1.1 km to 4 km |
| M (Medium) | 4.1 km to 10 km |
| G (Good) | 10.1 km to 20 km |
| VG (Very Good) | 20.1 km to 40 km |
| E (Excellent) | Greater than 40 km |
Humidity is the amount of water vapor in the air. If there is a lot of water vapour, the humidity will be high. The higher the percentage of humidity, the wetter it will feel outside.
UV exposure index and the protection required to help keep you safe:
No risk of UV - It’s safe to stay outside. Low - You can safely stay outside. Consider sunscreen in direct sunlight. Moderate - Take care during midday hours and do not spend too much time in the sun unprotected. Sunscreen advised. High - Seek shade during midday hours, cover up and wear sunscreen. Very high - Spend time in the shade between 11am and 3pm. Shirt, sunscreen and hat are essential. Extreme - Avoid being outside during midday hours. Shirt, sunscreen and hat essential.

UK long range weather forecast
On Friday, cloud with patchy rain and drizzle are expected in the far north. However, dry, bright, and breezy conditions with sunny spells are likely for most. For the rest of the period, unsettled weather conditions are expected in the north whilst settled conditions are more likely in the south. As a result, showers and longer spells of rain with strong winds are likely in the north and particularly in northwestern parts of the UK. Drier conditions with light winds are expected across the southern areas, with overnight and morning fog patches possible at times. Temperatures overall will be near normal or above normal for most throughout the period, but overnight frost is likely in the south.
Updated:
While uncertain, a continuation of the regional divide between the north and south is expected as the broad theme for this period. Unsettled conditions are more likely to dominate in the north while the south remains settled and drier. A spell of more widely spread wet and windy weather is likely to persist for several days across all areas, although wettest conditions will focus in the west. Temperatures are most likely to remain around average or above.
