Switch to colder pattern will be temporary, still more mild weather to come in January. NEW! Stowe, Vermont Snow Cam.

Mt. Mansfield should get 6 to 12" by Saturday.

What has been going on this winter?
      We have been under the influence of La Nina, a very large pool of cold water in the Pacific.  Also factoring in are the Indian Ocean which is warm, and some cold water near Greenland.  All this has caused the jet stream to ride further north than usual.  Although there are predictions of a switch to a colder pattern, it has been very slow to show up.  The remainder of January still has some mild weather in it.  But this weekend will be colder, noticeably so.

Last winter we had a negative NAO which is a large blocking high pressure near Greenland.  This forces cold air south, toward the Eastern Seaboard.  It is not there this year, so far.  So, no snow.
