What does MOS mean in ForeFlight weather?
Model Output Statistics
But you will find MOS in the latest release of ForeFlight Mobile. MOS stands for Model Output Statistics. As the name suggests, MOS is derived from the output of weather prediction models developed and run by research meteorologists at NOAA.
How do you read a weather report?
SUMMARY BOX
- Precis. “Windy. Mostly sunny.” Less than 5 words, to describe the main parts of the expected weather.
- Chance of Rain. This is the likelihood of any rain in that location, from midnight to midnight.
- Rainfall Amount. If it does rain, the likely amount. The range is also a ‘percentage’ chance.
Are TAFs accurate?
TAFs are a valuable pre-flight planning tool, and they are created by experts who carefully consider a variety of different models and weather reports. But don’t be seduced by the precision of these forecasts. As you conduct your pre-flight weather briefing, consider the TAF a single data point, and nothing more.
What are the four weather symbols?

What do isobars close together mean?
very windy
The lines around high and low pressure on a weather map are called isobars, or lines of equal pressure, as shown in the above image on the left. When isobars are close together it is very windy; when they are further apart, conditions are more calm. The wind around highs always blows in a clockwise direction.

What do the symbols on the weather forecast panels mean?
The lower two panels show the forecast surface weather and depicts the forecast locations and characteristics of pressure systems, fronts, and precipitation. Standard symbols are used to show fronts and pressure centers. Direction of movement of the pressure center is depicted by an arrow. The speed, in knots, is shown next to the arrow.
What is the forecast visibility code for significant weather?
Forecast Visibility—The forecast visibility is given in statute miles and may be in whole numbers or fractions. If the forecast is greater than 6 miles, it will be coded as “P6SM.” 7. Forecast Significant Weather—Weather phenomenon is coded in the TAF reports in the same format as the METAR.
What is an aviation weather report?
