Wrong again. The only map I said was pointless was the 300 whatever hour snow map. A week ago it had us “trending” towards 14 inches of snow this past week. Actual total…..0.

False. It’s only produced a few times per month. The models and CPC have been trending warm in the long term for almost a week now.

Good read on the stats Slim! Remarkable how last Fall and this Fall each month has had almost exactly identical mean temperatures. Another interesting note, of the top 10 least and top 10 most snowiest Decembers, 11 of them have been in the last 20 years. Seems to be feast or famine when it comes to December snow, and with the way the outlooks are trending now, this year could be another December for snow famine.

I would like to see Harbaugh get this monkey off his back. Ohio State is loaded, so it would be a huge win for Blue.

Speaking of Blue, well look at who is the hottest basketball team in the country. This is good for our state and the B1G.
