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.

UK long range weather forecast
Sunshine and showers can be expected Wednesday as rain generally clears away from the southeast, while heavier and possibly thundery showers may be expected in the northwest. Winds moderate to fresh, and temperatures trending slightly above average. Unsettled weather continues for many, with showers affecting northern areas and likely to spread southwards. Temperatures turning normal or cool, and becoming windier with gales possible in places. Confidence remains low throughout the rest of this period. High pressure may develop across the UK, with likely occasional frontal systems bringing periods of rain. However, towards the end of the period, deep lower pressure may be expected, with temperatures generally returning to above normal, however, cooler nights make way for potential mist and fog.
Updated:
We may expect to see lower pressure dominating through the rest of October; however, confidence remains low through this period. A lower pressure regime is likely to bring periods of rain across the UK, however some drier spells and potential mist and fog can be expected too, most likely at the beginning of the period. Temperatures likely to remain above normal throughout.
