2/24: 10PM Tuesday Snow Update for WEDNESDAY/Thursday

Okay, so the very latest Evening Data from the GFS, NAM, and even the RPM showed some changes. (SNOW Lovers, NOT your Blog Post to Read from )

1. RPM:  Earlier this Afternoon, it showed some "moisture" arriving in from a Rain/Mix to Light Snow through Early Thursday Morning.  RIGHT NOW, the SnowDome turned on tonight keeping any Snow along the Southern 1/3 of TN, and anything Along & East of the Plateau.  It keeps rest of TN Dry....dry....arid...scarce :(

2. NAM:  This Model Guidance still showed some changes as compared to the Morning Run data.  Earlier it showed snow developing from 3-6PM Wednesday...now the storm has slowed down making the Snow want to begin now 6-9PM all across Middle TN.  It will, as stated in previous post, a quick hitter.  After Midnight, the Snow should be tracking towards the Plateau.

NAM Amounts:
 * Trace-1" for Nashville
*  2"-3" for South/Eastern TN



3. GFS:  Nothing much to go in-depth with the GFS.  Its agreeing alongside with the NAM from this Evening for Tracking, Timing and "lack" of Intensity for MiddleTN.  Its prefers the "Southern Track" keeping the better Snow Amounts in Southern 1/3 of TN and much of Eastern TN.  But it does have the Timing like how the NAM plays out for Nashville; beginning around 6-9PM and then moves Eastward after 1-3AM Thursday.

GFS TOTAL SNOWFALL

** Only thing I see different it keeps Southern KY drier than the NAM.  This will NOT be a Heavy Snow event, maybe some "Flurries" for Bowling Green with a Dusting if best.











GFS AMOUNTS:

Nashville: Dusting - 1"
South/Eastern TN:  2-4" 



















THOUGHTS:
  -- Little under 24 hours away from start of the event, but we have to watch the Short-Range Data by Morning (SREF, HRRR) before the event begins.  I do think if the Track stays "on course", expect Lesser Amounts like a Dusting to 1" for Nashville area...and Higher Amounts farther South and East you travel.

*** DISCLAIMER:   There have been times where a System "jogs" North about 50-75 Miles right before the Storm moves in.  IF (a big IF) this happens, I may bump the amounts a little Higher, which could see our Timing a little faster (4-7PM)..not (6-9PM)  We will see!
