It's called a synoptic chart, and you do sometimes see these on American forecasts. But, notice that it's quite difficult for the average person to interpret how these lines are going to affect things. In my prior visits to Oz, I have learned that a cluster of pressure gradients close to one another means that it will be windy, and a Low is usually a sign of rain. But troughs (the dashed lines) are a new concept for me, and I don't really see how this is going to give me a reliable view of future weather. For comparison's sake, look at these Weather Channel maps:
WeatherZone. Note the distinctions between "Rain periods," "Rain at times," and "Showers about." I have also seen "Rain easing.."
- Wednesday. Rain at times. Moderate to fresh S to SE winds
- Thursday. Rain periods
- Friday. Rain periods
- Saturday. Showers about
- Sunday. Fine
