Update 8:00 a.m.
The snow ended early this morning and the wind didn't let up a bit all night. With gusts sustaining in the upper 30 mph range, it made for some difficult snow measurements this morning. I made multiple measurements around the yard, and came up with a 2.0" total. This storm reminds me of the January 6-7, 2010 storm. Strong NW winds made similar drifting patterns, although more exaggerated due to double the amount of snow then. Pictures from that storm can be found here. Compare those with this year's storm.
Here are a couple of pictures from the storm:
Update 12:00 a.m.
Snow is currently falling with vigor in Missouri again. After much anticipation, we will reach our first inch tonight. We reached our maximum temperature of 46° around 10:00 am, and by 10:00 pm we were at 17°. Morning rain changed to a mist, and then quit for a while. Around 2:00 we started seeing flurries flying around, which intensified bit by bit through the evening hours. Tonight, at 12:00 am snow is falling at a moderate rate and wind gusts are reaching 40 mph. The current temp is 16°.
I tried to make a measurement, and my best estimation is a current depth of 0.5". Below is a video I shot and the coinciding radar image at 11:45 pm.
