Yesterday's precipitation event ended here at the house around dark - total was only 0.15". Looks like 100% coverage across the ALERT network again. Amounts were light, but somewhat better than Saturday's event. There were 7 sites that measured rain amounts of more than 0.25", but no amounts of 0.50". snow amounts unknown, but roads to Mt. Lemmon and Madera Canyon were closed yesterday afternoon. Once again Atmo's WRF-GFS provided excellent forecasts. Actually, some school delays and closings today across southeastern Arizona! Photos of the Catalinas and Kitt Peak at sunrise today are above and below.
This was the second event this winter where I wanted to check on what the observed 1000-500 mb thickness was. But once again the NWS RSS sounding system failed here at Tucson and there were no upper-air data. So it goes.
