If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION... Showers are likely tonight, likely all snow above
11 thousand feet with the snow level dropping to 8 to 9 thousand
feet by morning. Accumulations should be limited to areas above
9 thousand feet. Snow is expected to be light, but accumulations
of an inch or two are possible. Temperatures should be warm
enough to prevent accumulation/freezing from any showers on Trail
Ridge until around 8 PM, but a little accumulation is likely on
the road after midnight. Temperatures will remain in the 30s on
Thursday, so melting may be slower than the last event, but
melting is likely by early afternoon.

The next chance of snow will be Saturday, with another chance of
light snow.
