.DISCUSSION...
A cold front will approach the proposed spot location early in
the morning and should bring a small chance of snow showers in
the morning followed by brisk northerly winds and much cooler
temperatures. The winds will let up considerably on Thursday
with another colder and potentially snowier system arriving late
Thursday night or Friday. This arctic intrusion will result in
a prolonged period of sub-freezing temperatures so any snow which
falls may not melt of for a while.
