⚙️ Physics Predictor

No upstream rainfall to drive a prediction

Ground: VERY DRY ground (by pre-storm baseflow 0.6 cfs; about 1.5" of rain soaks in before runoff starts)

Engine: v2 (offline-fit convolution in cfs)

📊 Empirical Forecast

No rise indicated by recent rainfall

Soil: DROUGHT · Confidence: CALIBRATED

Details

Calibrated chance the gauge rises from BELOW_LOW to LOW within the next 12 h, from 6 h rainfall (0.0 mm) at this gauge level (history stratum gq0); ground DROUGHT by 7-day rain. Experimental.

Rain columns are context, not a probability: the 6-h rain that fell before past rises to each level (quartiles of n past rises; the population is noted under n). This basin: 0.00" so far in the last 6 h. The Chance column is the calibrated forecast.
