10/30/2009 7:00 AM 0.52 M M M M +TSRA fell with 35 mph winds, thus with my very exposed gage very possible it was underestimated. +TSRA began at ~6:30 AM on the 29th, and fell for about a half hour, decreasing to -TSRA for another hour or so. An inch of rain fell in the first 17 minutes.

12/25/2009 7:00 AM 0.59 7.0 M 7.0 M Likely a severe undercatchment because of the tremendous winds and exposure of our property. We live on top of a hill without many trees, and at no point during this precip event did the sleet or snow fall at less than a 70 deg. angle off the vertical. Because of our exposure, measuring the snow depth was equally impossible. I had to take an average across the 2 acres, which came out to about 7 inches though widely varied from 0 to 18 inches away from the obvious snow drifts. We have a large patch in the back yard that was swepth clear of snow, approximately 40 x 120 feet. We had drifts to 2.5 feet. Here is the breakdown of precip: Sleet fell from 0800 to 1230 CST, then started mixing with snow. Winds were 35G50 mph at during this time. Heavy snow with large flakes began 1330, and snow was heavy until 1530 CST. At times, given the heavy snow and 40G55 mph winds, visibility droped to 200 feet (measured). It averaged 400-500 feet during heavy and moderate snowfall. The snow came to an end at ~2000 CST. It was quite a show, I only wish I was able to find a spot to accurately measure snowfall, but where I live that was impossible for this event.

Precip ended by 7 PM. 1" of sleet accumulation on top of 0.75" of ice. 0.75" is an average...some north facing elevated surfaces had more than that. The sleet/ice layer made for a perfectly flat (and cold) foundation to measure the snowfall that began the morning of the 29th.

There was an inch of sleet/ice underneath the snow that fell on the 28th.

However, it was SN or +SN at times, particularly off and on between 1:30 and 5 AM. I measured the snow depth at 6 AM as the snowfall was nearly over to get the closest estimate of the new snowfall. It didn't settle at all from 6 AM to 7 AM for the "official" observation. If it would have been just a few degrees cooler, we could have gotten 6-8 inches.
