This is only available at selected airfields. It is intended to indicate significant changes of weather in the two hours after the observation is made.

Putting it all together. OK, that's the details so lets take a look at some examples. The report was measured at UTC and it shows that Amsterdam was reporting a wind of at 15 kts, the visibility was 9km m , it was raining, cloud was scattered at ft and broken at ft. Temperature was 10C and dew point 9C, the sea level pressure QNH was mb and there was no significant change expected in the next two hours.

This would seem to indicate the passing of a slow frontal system across the area with only a slow improvement in weather conditions during the day. This shows that Heathrow at UTC was giving a slight 5kt westerly wind with no cloud or visibility problems, a moderate temp of 15C and normal pressure of Temp and Dew Point are down at -2C and the trend is of little consolation with the cloud only forecast to increase to feet.

A nasty cold and windy day with strong gusty 35 kt wind up to 55kts at times and swinging from to degrees. Visibility is reduced to metres in heavy rain showers and a low cloud cover of feet and solid Cumulonimbus at ft to add to the misery. At least they expect the visibility to increase to metres even if only temporarily. Forecasted visibility of six miles or more is always referred to as P6SM. There is forecasted to be at times between and hours visibility at 5 statute miles, rain showers, snow showers, and mist with an overcast layer of cloud at feet.

There is also forecasted to be at times between and hours light snowshowers, visibility of two statute miles, and an overcast layer of cloud at feet. Open navigation menu.

Example: G27KT this indicates that the average wind is at 15 kts but gusts to 27 kts are recorded. If the wind is calm then KT will be shown. Example: G27KT V shows that the wind is blowing from the northwest at 15 kts with gusts to 27 kts but that the wind direction is varying from to degrees.

Visibility Visibility is recorded as a four figure group in metres metres is roughly 1 nm. Weather Weather is identified by one or more two letter groups. Cloud Usually this is a six figure group and one that most of you will already recognise. Cloud amount is given as; FEW Few. OVC Overcast. This indicates 8 oktas solid cloud cover. Examples: SCT - Scattered at ft. Examples; Q, Q Recent Weather This may be included if appropriate using the weather codes above, prefixed with RE for recent.
