.DISCUSSION...Expect snow to continue off and on today as a cold
front works through the region. Most winds will shift to southwest
and increase in many areas to over 30 mph. It will turn colder
behind the front. Generally expect 3 to 6 inches additional inches
of snow today above 7500 feet with lesser amounts below that
level. Could also see isolated thunderstorms this afternoon as
well with increased instability along the cold front.
