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
On Tuesday, snow showers are expected to continue across the northeast of the UK. An increase in cloud cover is likely in the southwest. Dry weather conditions will likely dominate for the rest of the UK. Moderate to strong southeasterly winds likely in the south and west, feeling bitterly cold in places. After Tuesday, cold conditions are likely to stay for the majority, with wintry showers mainly along the coasts. Often dry and cold inland with widespread hard frosts and patchy freezing fog predicted. There is potential for areas of cloud, rain and strong winds to spread across the south, bringing a mixture of rain and snow for a time. Temperatures are likely to be below normal through the period but may increase nearer to normal in the south later.
Updated:
General themes remain uncertain for the rest of the period. Conditions may be widely changeable, with some spells of rain, and at times snow. These expected to be accompanied by strong winds, initially focused in southern parts, but affecting all areas at times. Colder and more settled conditions with occasional wintry showers could continue, particularly in the north. Temperatures gradually returning closer to average towards the end of December and start of January.
