Weekend Snow? It's Possible, but I wouldn't get too excited yet

As Chief Meteorologist Ty Shesky touched upon Monday evening, our first accumulating snow may not be that far off.  The first snow chance will be along a cold front moving in from the northwest late Thursday.  But because it's lacking any significant moisture we're only expecting a few flurries from it.  It will, however, pull down enough cold air to keep temperatures in the 30s going into the weekend.

The latest evening run of the GFS weather computer model develops an area of low pressure in east Texas Saturday and lifts it up through southern Illinois and into Indiana by Sunday morning.  At the same time a stronger cold front will move in reinforcing the cold air already in place.  With temperatures below freezing, this one particular model is producing shoveling snow by Sunday morning. 

Now before you get too excited, I must stress that this is only one of many weather models I look at in the morning.  And at this point this is the only one that is tracking the low to our east.  The rest are actually moving the low further west which would produce more of a rain/snow mix.  This time of year our weather models have a tough time resolving big changing patterns, so as the weekend nears we'll have a better handle of which storm track this low will take.
