Trigger at a message from one node, but output a message object from another node

I'm building a weather dashboard. Once the user gives an input, the weather at that location gets updated every 30 seconds (the user can change this value). The user can set a limit for each parameter (temperature, humidity, wind speed). If the value for each parameter at that location surpasses the limit, the dashboard displays a warning message.

With my current dashboard, the warning message only shows once. I want to display it every time the weather gets updated (at 30-second intervals by default, or at the user-defined interval).

I tried connecting the trigger nodes for user input to the warning message nodes, but then, it overrides the payload message. If I can connect the trigger node for weather data, but make sure it does not override the limits set by the user, this will solve my problem.

The working flow is attached below.
