Why operational weather tools should stay small

Dashboards often become slow because they try to show everything. A useful operational tool starts with one question and makes the answer obvious.

For a warning system, that question might be: do we need to change the plan in the next six hours? The interface should prioritize the threshold, timing, confidence, and next action.

Satellite imagery can provide context, radar can show what is arriving, and model guidance can show what may happen next. The interface should help a forecaster compare those signals without making the operator study the entire system.

Fewer moving parts also make systems easier to maintain. Stale data, confusing states, and decorative features should never hide the important signal.

Fast software is not only pleasant. In a changing situation, speed is part of correctness.
