217 AM MDT SAT SEP 24 2016


Low pressure will move away from the region today. Expect to see
improving conditions throughout the day with low chances for a few
residual showers across the eastern highlands today. Expect
excellent radiational cooling tonight so fog and/or frost may
develop especially across the middle and upper snake plain. Will
issue a frost advisory for tonight, think fog will remain patchy but
frost could be a bit more widespread. Expect quiet weather with a
gradual warmup into mid week as high pressure settles over the
region. Could have another frost possible Monday morning across
portions of the snake plain. A cold front will approach the region
late next week. This will bring the next chances for showers and
thunderstorms the region.
