Big Snow Storm Late Next Week?

Here's the when, where, and why. 

At this time, the information we are receiving from the weather models is very interesting for next Thursday and Friday.  Right now, there is the potential for a significant winter storm to affect the WHAS11 viewing area by late this week.  However, the heaviest snow potential is over southern Kentucky, mainly areas south of Elizabethtown, KY.  The GFS weather model is pumping out more than 11 inches of snow for Bowling Green by next Friday!  You can follow along with this link here...

http://66.70.209.226/weather/snow/kbwg.txt (it can be hard to read, go over to the "TotSN" column, and go down and that is the total snow accumulation.  The time is in Zulu  (GMT/UTC) time, you have to subtract 5 hours from our military time.  So, 00z is 7pm EST)

Below is a map of the expected snow by Friday per the GFS model.  Notice how the width of the band of heavy snow is fairly thin covering southern Kentucky and northern Tennessee.  But, what is alarming is the amount of snow.  The dark and light blue areas in the middle represent 8-12 inches! 

Below that map, is the Hydrological Prediction Center's (HPC) QPF map, and they are forecasting a similar amount of QPF (liquid precipitation).  This doesn't show what type of precipitation will fall, just how much if it was all liquid.  But, if the QPF in Bowling Green is over an inch, then the snow amounts could be over 10 inches, if the cold air matches up just in time (assuming a 10:1 snow/liquid equivalent). 

Keep in mind, this storm is still five days away.  The track and/or the intensity of the storm will likely shift in some way, and this could change the amount and location of possible snowfall.  The current outlook is just perking us up a little bit.  Make sure you keep up-date-date with the changing weather forecasts over the next several days.  Either way, January is making a big comeback with some very cold air this week!
