One of the primary ways of representing the weather is the use of surface weather charts. We all should be familiar with these. The surface weather chart should be the first thing you look at to build your mental picture of the current and expected weather conditions.
The chart could be historical; - an analysis of the situation at a particular time; or it could be a prognostic forecast chart for some time in the future. So check the type and time of the chart. You may have both, the most recent analysis and the latest prognostic chart. Remember, all chart times in MetFlight are in UTC.
The MetFlight GA image looper function is a helpful tool for looking at the progression of the weather as depicted on the standard analysis and prognostic charts.
