Chance of Snow or False alarm?

Remember back during the end of October we had a surprise snow event.  Everyone including meteorologists were caught off guard.  Again, for the last three days, weather reports flip back and forth from it being cold to not being cold enough for the rain / snow changeover later this week.  

Some online forecasters are stating that there is a dividing line where the air maybe just cold enough to change the rain to snow.  Before on that last event I mentioned, I wrote that the snow would not stick because of the warmer temperatures the day before would not allow the snow to stick to the ground.

Update 8:44pm 12/5/2011:  The National Weather Service has issued its updated forecast.  Possible rain changing to snow.  Snow showers from Tuesday night, then again Wednesday night into Thursday morning.  Looking at the forecast details, they say we should not get anything more than a 1/4" of snow on either of these two days. 

I would be more concerned of the Fog that will be out there again tomorrow morning!

  I am sure everyone is thinking why I am writing all this.  With definite signs of climate chance, you have to be aware of changing weather that can affect your local community.  Just yesterday I read that parts of northern Texas were expecting snow.  Further updates will be posted just in case the slow moving low pressure system, pulls in enough cold air to make it snow more than what is being stated.
