10/5/2012 8:00 AM T M M M M Watching the rain consistantly miss Bull Valley (and the greater McHenry County) is alarming. Rain gauge had one drop of moisture in it this AM. Yesterday about 3 pm I was 5 miles west in Woodstock and enough rain drops were falling that I had to turn on my windshield wipers.

New and Total Snow are the averages of many measures. .68 today and .9 yesterday gives a storm total of 1.58 inches of much needed precip. Happy Solstice!

2/8/2013 8:00 AM 0.89 7.1 M 10.0 M 22 degrees and overcast. wet heavy snow - trees and shrubs are coated with a lovely frosting. I thought snow might have settled in the night, but today I found average of 7.1 inches of new snow on board and average of 10 inches total snow on ground. Significant weather reports filed yesterday: 12 noon: gloppy rain turned to flakes. 2 pm 2.1 inches new snow 4 pm 2.2 inches new snow 6 pm 1.0 inches new snow For a period of at least 30 minutes around 8 pm flakes appeared to be spatial dendrites (compared to samples on Snowflake Report). 8:30 pm 1.2 inches new snow 11 pm 0.6 inches new snow. Also, when I added warm water to snow in the gauge and it melted, I observed a glazing of solid ice on the bottom that I then melted with more warm water. This probably was the freezing rain that fell in the morning before the precip turned to snowflakes around noon. The ice that I melted amounted to 0.15 inches of the total 0.89 inches of precip (after I subtracted the amount of water that I added). Cheers for the snow!

I am leaving new snowfall and total snow as NA because the wind was blowing so hard and the snow was flying at 8 am that I am not sure what really fell. There was an average of 0.1 inches of new snow on the board and 1.0 inches on the ground. But a more protected measure that I take and never report had 0.8 inches of new snow. This protected area that I measure for my own curiosity usually correlates very closely with what I measure on the snow board.
