2/28/2011 7:00 AM 0.11 1.5 0.09 32.5 6.81 Yeseterday: 1.5" snow, 0.09" H2O. Today's precip was "dry" and "wet" sleet. The "multi-precip" gauge has some ice tracks ending at a sleet particle. Those are left by partially frozen sleet. Cars and railing have some loose sleet, that started dry. Air temp is 23F, there is some fog around, so warm air may be nearby. No precip at the moment. SWE shows no run off since Feb 21 report.
3/1/2011 7:00 AM 0.68 0.3 0.25 31.0 M Snow board had 0.3" of sleet/rain frozen crud. I tried to get a "decent" core from it but lost it all when the ice broke free. So the water in the core is a guess. Does anyone read these comments? I sure hope not! :-)
