Moderate Snow Wednesday Night into Thursday Morning

The NWS doesn't see fit yet to post a Winter Storm Watch, but I am fairly confident that a moderate to possibly heavy snow event will unfold here in our area starting late Wednesday and last into early Thursday.  This is just a very brief post to show you the latest model output of the NAM and its depiction of how this will all play out.  The maps I am using show the Rain-Snow line as a bold line marked by 0ÂșC.  Note that on the first map we are very close to that line, but that critical line steadily moves east and all of the precip will be falling as snow.  Here is the map as of 10 pm Wednesday evening...
Then the period ending about 1 am Thursday morning....that is a quick heavy burst of snow in our immediate area!
And then the storm pulls away as shown at 4 am Thursday morning...
So it is now appearing that this quick hitter will dump a plowable snowfall for our area.  Cold air will then be moving in for the weekend...here is the forecast temps for kickoff in Altoona Saturday evening.  That has temps in the low 20s with what you can't see...some wind!  It will be cold!
Gotta go....have a terrific Tuesday!
