First short wave from 36-hours ago is producing blizzard conditions over parts of Northern/Central Plains - above is webcam from Lexington, Nebraska.
This morning's 500 mb analysis from SPC (below) indicates the next short wave is currently over the Northwest - from Idaho southward across Nevada.
The 06 UTC GEFS plumes forecast this low-moisture system will pass quickly by tonight - forecast for PW above spikes at a bit less than half an inch, while QPF forecast for TUS (below) has average of less than 0.20" - forecasts similar to last event. The 06 UTC run of the WRF-GFS at Atmo forecasts a period of gusty southwest winds this evening - forecast at bottom valid at 8:00 pm MST later today.
