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

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.
