DISCUSSION
 
THE SHORTWAVE TROUGH CONTINUES TO CROSS UTAH THIS  
EVENING, WITH THE H5 AXIS CUTTING ACROSS UTAH FROM NE-SW. SOME  
LINGERING INSTABILITY REMAINS PRESENT, WITH AN 18-20C DIFFERENCE  
BETWEEN H7 AND H5. AS A RESULT, SOME SPOTTY SNOW SHOWERS REMAIN IN  
PLACE, BUT WILL CONTINUE TO GRADUALLY WIND DOWN THROUGH THE NIGHT AS  
LARGE-SCALE SUBSIDENCE STRENGTHENS FROM NORTH TO SOUTH. BEST  
ACCUMULATIONS WILL BE NEAR THE HIGHER TERRAIN AND I-15 CORRIDOR OF  
CENTRAL AND SOUTHWEST UTAH AND IN THE TOOELE VALLEY WHERE EXISTING  
SHOWERS HAVE BEEN ENHANCED BY THE GSL. HOWEVER, ADDITIONAL  
ACCUMULATIONS SHOULD REMAIN AN INCH OR LESS IN MOST AREAS, SO HAVE  
EXPIRED/CANCELLED THE REMAINING WINTER WEATHER ADVISORIES.  
 
HIGH PRESSURE WILL BUILD INTO THE AREA TOMORROW THROUGH THE FIRST  
HALF OF THE WEEK. THIS WILL BRING A PERIOD OF DRIER CONDITIONS WITH  
TEMPERATURES TRENDING WARMER.  
 
UPDATED THE FORECAST MAINLY TO ADJUST POPS AND WINDS FOR THE REST OF  
THE NIGHT.
