Some sleet, and rain may mix in Wednesday evening, and early Thursday especially across Southern Vermont, and elevations below 900 feet.

DISCUSSION
     Very quick discussion as I need to get back to work. I have cancelled the Winter Weather Advisory for the Champlain, and St. Lawrence Valleys, as sun earlier this morning allowed temperatures to sky rocket some 10+ degrees in 1 hour. Now that the clouds have moved in temperatures will hold near steady or slowly rise with the Southerly Winds. As of now the winds are well below Advisory criteria, but the wind threat will continue to be monitored. Winds may increase significantly over the next hour or two, as evaporative cooling tries to occur, which will help mix down some strong winds as the precipitation moistens the very dry atmosphere. Winds will likely be strongest in the Champlain Valley. Updated maps below...
