December arrives on Friday! So where should you ski this weekend? That's an easy answer: Jay Peak. They've reported 22" of snow this week. Have you seen the reports? I'm jealous. They already have several trails and a few glades open with natural snow.
The snow isn't done yet. Another several inches (maybe 6?") is expected before the weekend.
If you're not skiing this weekend, this is your opportunity to complete preparations for winter. This may be your last chance. Finish leaf cleanup, and make sure the snow blower is functioning. But seriously, you should be going to Jay Peak. Start packing.
Temperatures will be seasonable this weekend, but warming up into early next week.
Around Tuesday - Wednesday, expect a dramatic regime change. The transition itself should bring precipitation, though the details of how that happens remains unclear. From late next week onward we'll see dramatically more wintry weather. Expect ample cold air and opportunities for snow.
