I've seen that much snow melt off in just a day or two, especially if we get some rain the next few days.

March can be very up and down.

I'm not far from you at all. This was an odd winter here, with tons of snow coming very late -- so we do have more snow on the ground than usual for this time of year, and it is still very cold. However, you're comparing it with the last few years: the past two winters have been milder and with less snow than usual, and last year was the earliest spring we have EVER had. I played golf on March 11 last year! There have been PLENTY of years when I couldn't plant early cold-weather crops (like onions or peas) until late April or early May because of snowpiles that hadn't yet melted.

I still have a solid 2 feet of packed snow across the yard... at least 5 feet in the deeper parts (I know, because I still cannot see my rugosa rose and it was trimmed to about 5-6 feet high before winter, to minimize snow damage).
