While we've seen exceptionally dry conditions so far this Fall, we can prepare for heavy snowfall due to a polar vortex coming to much of the northern U.S. according to the National Weather Service. About two feet of snow is being predicted for the northern and central Rockies. However, the drought monitor still is showing abnormally dry to extreme drought conditions in the southern U.S. as predicted by NOAA for the 2016-2017 outlook of a weak La Nina system.
