Just a spot for weather or not

With the official start to winter I thought I'd bring back the snow-counting from Lakeshadow on Sully's blog back in the "old days." As I recall, this is an old Iroquois (Onondaga?) method. The following is from LakeShadow's blog:
Snow Counting Rules:
How many snows will you get this year?
The calculation for snow-counting is as follows:
F + N = S ( F= First Snow Date of Month; N= Number of Days Since Previous New Moon; S= Snows For Winter)
Add the date of the month which you receive your first qualifying snow (see "What counts as a snow", below) to the number of days since the last new moon.
For example: Its forecast to snow on Oct 28th here in the Buffalo region. The last new moon was September 29th. It will be 30 days ago that there was a new moon from Oct 28th. add 30 (days since new moon) to 28(day of month) and you get 58. That is the number of snows that will be expected if the predicted snowfall happens.
What counts as a snow?
A snow is counted when there is enough of it to track an animal and it doesn't melt until the next sunrise or sunset. For example, if it starts to snow over night, it must cover and stick to the ground (grassy surface...not pavement) the next morning without melting for it to count. If it starts snowing during the daytime, it must still remain on the ground through sunset. This is easy to determine by watching for animal tracks or by putting a footprint in the snow once it stops snowing.
A new snow is counted when
a.) snow has melted between snows (after it has remained long enough to count in the first place) and surfaces are recovered to fit the snowfall criteria.
b.) Snow from the previous snowfall remains for the required time to be counted, new snow covers the footprints tracks left by animals and tracks stay covered through the following sunrise/sunset.
Many snows are too light to track an animal or melt away too quickly to be counted. So remember to take note...can you track an animal in the grass and has it stayed through the following sunrise/sunset.
If a snow is continuous through a few days without letting up through the following sunrise/sunset, it is only considered one snow. in other words, sometimes it snows for a few days and still counts as only one snow. On rarer occasions, two snows can be counted in one day. For example.. It may snow over night and stop before the sun rises, yet the snow remains on the ground past sunrise. Then the snow starts again in the afternoon while it is light and lets up before nightfall, covering all morning tracks and remaining on the ground through the following night. This counts as 2 snows for one day.
Thanks for visiting and participating!!! Keep us all posted on how you do with your corner of the world!!!
I thought this was fun so I'm doing it again. My first snow was Dec. 14, last new moon was 9 days before, so 14+9=23. I hope we come close:). As of 12/21/10 I'm at 2 snows.
