A Shift

The forecast is still too tricky to make a full blown call on. The data is making a few shifts!

By 4pm on Thursday I will have my first call for snowfall graphic ready for you guys to check out! Right now, I will focus on what we have seen so far in the data today! The cold Arctic air invading the region is looking pretty strong and keeps pushing the energy farther south. If this trend keeps going... snow totals will be much lighter. That could also mean we'll see the swath run away from I-64. Will there be another NW turn in the data? I am beginning to think that may not happen!

NAM Fri Afternoon

GFS Fri Afternoon

Both the GFS & NAM have the low taking a pretty southern track here early. Still the GFS is favoring some heavier bands of snow across extreme southern KY at that time!

NAM Fri Evening

GFS Fri Evening

The distrubution of the moisture is quite different with these two! The GFS is making a pretty deep run into KY and the NAM keeps it right along the Hal Rogers Parkway. If this track hold... the KY/TN border will see some decent snowfall.

NAM Early Sat

GFS Early Sat

The track means everything! You may have heard this... 50 mile means 5"  This is true! There will be a shapr cut-off with the snowfall out of this one. It will mean 5"-10"

There isn't much more that I can say until I issue my 1st call on Wednesday. I will show you the latest model snowfall forecasts.

12z GFS                                                                                   GFS 18z

  

I haven't seen the 0z run of this yet... when I do I will post a quick post and let you guys see it too! The totals keep getting cut back and a little farther to the south each time we look at them here lately!

Remember... my first call comes tomorrow around 4pm! 

C-Ya Bye
