.DISCUSSION...Some very light snow is possible in the mountains
through this evening, but the bigger issues through Wednesday
afternoon will be warming temperatures (especially at lower
elevations) and winds ramping up...starting this evening. Wind
gusts over 30 mph will become more common at highest elevations by
Wednesday. Current timing has snow beginning in earnest Wednesday
evening around Galena Summit and the Stanley basin, but not really
spreading into the Wood River area and Soldiers well after
midnight. The bulk of the snow should end by noon Thursday, with
lingering showers the rest of the day. This is not going to
produce a lot of snow within that window, but early numbers show
3-6" inches above 7000ft and up to 3" below that.
