@sartoric said in Weather trend indicator thresholds:
afair it shows a 3+3 variation
Correct.
It shows a 3-and-3 hr window, but the old documentation states that the arrow up or down indicate a >2hPa change. Otherwise it should show a horizontal line/arrow.
I don’t see such a big change in the graph, but the indicator tells me pressure has dropped and increased more than 2hpa
