Winter Storm: Mar. 19/20 Update #4

Just a quick update with the 12z model runs...  Amazing to think I'm sitting with the sliding door wide open letting the great outdoor air in at the moment, give another 12 hours and we'll be nearing 32 degrees and snow!!

The 12z NAM stays consistent with the frontal passage across Kansas and Missouri during the overnight hours, however, has changed the trowel strength and maximums once again.  With a surface low path further south compared to previous runs the best area for significant snow will be over parts of Oklahoma into extreme southeast Kansas and perhaps into portions of southwest/western Missouri. The 12z GFS is similar with a surface low track through Arkansas just a little further southeast, thus the best trowal now located a little further southeast away from the Kansas City Metro. 

Will likely get the 'live' setup going late tonight after I arrive home from work, but may not turn it on until the early morning hours so that there is truly something to view besides a dark view of the ground.  Expect to see white ground by sunrise Saturday over Kansas City, with total accumulations of ~4" along and south of I70, with 2-4" for the areas north of I70.  An additional update is likely tonight ~11PM or shortly thereafter...
