THE UPPER TROUGH WHICH BROUGHT WIDESPREAD  
PRECIPITATION TO MUCH OF THE FORECAST AREA TODAY CONTINUES TO  
ROTATE EASTWARD THROUGH THE CENTRAL ROCKIES THIS EVENING.  
SUBSIDENCE IN THE WAKE OF THIS DEPARTING WAVE HAS BROUGHT AN END  
TO PRECIPITATION ACROSS ALL BUT THE FAR SOUTHEAST, AND THIS  
ACTIVITY SHOULD BE ENDING WITHIN THE NEXT HOUR OR SO. MID LEVEL  
RIDGING IN THE WAKE OF THIS WAVE IS FORECAST TO BUILD ACROSS THE  
REGION SUNDAY BEFORE THE NEXT IN THE RECENT SERIES OF WAVES DIGS  
INTO THE GREAT BASIN LATE SUNDAY NIGHT THROUGH MONDAY, BRINGING  
YET ANOTHER ROUND OF VALLEY RAIN AND MOUNTAIN SNOWFALL.  
 
UPDATED EARLIER TO REMOVE POPS ACROSS MOST AREAS FOR THE REMAINDER  
OF THE NIGHT.
