Make that 3. That's my time period as well. Around the 2nd-3rd of Feb is usually my cut off line then you have to hope for overnight snow. Sure, you "can" get snow during the day after that but it's usually slop which melts on the road as soon as the intensity lets up. You would need perfect conditions for a daytime storm. (temps in the 20's, low dense clouds and snow intensity)
Overall, I've given up and would cash my Winter chips in now for a much below normal (temps) Spring and a below normal Summer. This Winter has been boring torture and not the least bit fun.
