2/16: POST STORM Recap...COLD Weather Looms

WHEW... What a MONDAY many experienced.  Personally, I have not experienced this much Winter Weather since I was forecasting out in Casper, WY.  Though we had more snow, but the craziness i saw on TV, reports on Social Media was getting bad.
** This was back in October '13 where the city received 16" and I forecasted actually 10-16" the night before.  Weight of the Dense snow toppled the Trees and many broke on power lines; several power outages as this was one Casper's Top 10 Snows.



HOW MUCH Snow fell in KY? Here's a map that shows who received what and it clearly shows where that zone of banding that draped South of the WK/BG Parkways and into parts of South-Central KY.

SNOWFALL RATES were pushing up to 1-1.5"/HR this Morning and Early Afternoon in the pink and white shadings so it will be a snow (much of Southern KY) will remember for a long time.
- However, some parts near Louisville received some Drier Air i mentioned about last night from the Upper Levels so their amounts were lower. Highest Amount i saw was 13" in Richmond and 12" in Richardsville (Warren County; N of Bowling Green)

MIDDLE TN this Morning and Early Afternoon received some other precipitation type: Sleet & Freezing Rain.
The Northern Tier of the State, however, did receive Moderate Snowfall upto a Foot or more since their Temps were cold enough from the Column to the Surface to support Snow.

WHY this Mix Bag of Precip?  It all depends on the Amount of 'Warmer' Air aloft above the Surface.  Sleet has a lesser amount of Warmer Air above the Surface once the snow falls then melts, then goes back to Ice Pellets once it hits the surface.  FREEZING Rain is where its Snow...Rain once its melted and leaves the Cloud and then since the Concrete/Surfaces are already cold, it "Freezes" on Contact.
  ** About 1/4" to 1/2" of Ice Accumulated in Middle TN where some heavier bands dropped Isolated Spots of 1/2" to 3/4" of ice. That's serious damage to Trees and Power Lines!

-- TONIGHT, expect any Precipitation to diminish by Midnight. Skies will clear out and Winds should die down as Temps will drop in the Teens.

TUESDAY:  COLD...Highs only in Upper Teens/Lower 20°s for Southern KY and Lower to Mid 20°s for Middle TN and Nashville.

WEDNESDAY looks to be another Cold Day as a "new" weather maker arrives as a Trough drops through bringing Snow Chances. Not a large amount, but a nice coating is possible by Early-Mid Afternoon
  ** The latest RPM (shown below) wants to drape some Snow Squalls for the Afternoon and IF any develop, expect a quick Dusting or so of Accumulation through the Evening Hours.


These will be small bands, so who will see what is still hard to tell since they are little Microscale challenges.










THURSDAY MORNING will be Frigid!...like the Frozen Tundra Cold.. I think many Forecast Models will not handle the Lows due to the Snow Pack and Ice all over the Region.

*Since my Internet was disconnected I Am finishing this post by Phone. *
Ignore any Models you see, but I think much of KY will drop anywhere from -5 to -15 (Isol'd spots -15 to -20) of deep snowpack.
Middle TN will likely fall between anywhere from near 0 to -10 in some isolated spots.
IT WILL BE COLD. Bundle Up and bring in the Animals.
