AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
335 PM MST MON NOV 10 2025
SYNOPSIS
HIGH PRESSURE WILL REMAIN IN PLACE THROUGH
MIDWEEK CONTINUING DRY STABLE CONDITIONS. SOUTHERLY WINDS
INCREASE ON THURSDAY AHEAD OF A COLD FRONT ON FRIDAY THAT
WILL BRING VALLEY RAIN AND MOUNTAIN SNOW.
DISCUSSION
HIGH PRESSURE WILL KEEP CONDITIONS DRY AND STABLE
ACROSS THE AREA THROUGH WEDNESDAY. THERMAL INVERSIONS ARE
BECOMING MORE NOTICEABLE ACROSS VALLEY LOCATIONS WITH MONDAY
AFTERNOON TEMPERATURES AT HIGHER ELEVATIONS, SUCH AS ALTA, RUNNING
A DEGREE OR TWO WARMER THAN THAT AT KSLC. THIS WILL PROBABLY KEEP
TEMPERATURES A FEW DEGREES COOLER TUESDAY AND WEDNESDAY THAN
GUIDANCE SUGGESTS ACROSS VALLEY LOCATIONS.
SOUTHERLY WINDS WILL INCREASE ON THURSDAY AS A TROUGH MOVES INTO
THE WESTERN CONUS. HIGHEST WIND GUSTS WILL BE ACROSS THE WEST
DESERT, BUT THERE IS <20% CHANCE OF REACHING ADVISORY LEVEL WINDS
ACROSS THIS AREA.
GUIDANCE CONTINUES TO TREND TOWARDS A SPLITTING TROUGH SOLUTION
FOR THE UPCOMING STORM. THERE ARE CURRENTLY TWO SCENARIOS. THE
FIRST BEING THE SPLITTING TROUGH (60% CHANCE) AND THE SECOND BEING
AN OPEN WAVE (40%). THE SPLITTING TROUGH SCENARIO WOULD RESULT IN
LESS PRECIPITATION AND A MORE MODIFIED AIR MASS. MOST OF THE
PRECIPITATION WOULD COME IN THE FORM OF VALLEY RAIN AND MOUNTAIN
SNOW ALONG THE FRONTAL PASSAGE WITH THE HEAVIEST PRECIPITATION
STAYING FAR TO OUR NORTH AND SOUTH. THE OPEN WAVE SCENARIO WOULD
RESULT IN MORE PRECIPITATION AND A COLDER AIRMASS THAT COULD BRING
SNOWLEVELS CLOSER TO VALLEY FLOORS.
ASSUMING THE FIRST SCENARIO (SPLITTING TROUGH), CONDITIONS WILL
QUICKLY DRY OUT ON SATURDAY WITH NEAR BELOW NORMAL TEMPERATURES
SETTLING INTO MOST OF THE CWA. ANOTHER TROUGH IS APPARENT IN MOST
ENSEMBLE MEMBERS BY EARLY NEXT WEEK, BUT THERE ARE SOME
DISCREPANCIES REGARDING THE MAGNITUDE OF THIS WAVE.
