Classification: no_prediction Confidence: This event confirms the model correctly handles minimal rainfall scenarios under dry conditions, maintaining appropriate confidence levels
Minimal rainfall event (0.27" Band 1, 0.08" Band 2) produced no measurable gauge response, with gauge remaining flat at ~1.22 ft.

This was a very light rainfall event with Band 1 receiving 0.27 inches and Band 2 receiving 0.08 inches, concentrated in a brief 2-3 hour window around 10:13 AM. The gauge showed essentially no response, remaining flat at approximately 1.22 feet throughout the day. The gauge precipitation sensor recorded 0.0 inches, which is consistent with the minimal QPE amounts that fell well below any meaningful runoff threshold. The predicted peak of 1.22 ft was essentially correct for the baseline flow, and the lack of any significant rise validates that the current coefficients appropriately filter out such small rainfall amounts. This type of event provides valuable confirmation that the model correctly identifies when rainfall is insufficient to generate meaningful runoff, particularly under dry antecedent conditions (7-day average of 0.338 inches). No calibration adjustments are warranted since this represents proper model behavior - correctly predicting minimal response to minimal rainfall input.
