THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE WESTERN TWO THIRDS OF
UTAH AND FAR SOUTHWEST WYOMING.
.DAY ONE...TODAY AND TONIGHT
A COLD AIRMASS REMAINS IN PLACE ACROSS THE OUTLOOK AREA. EXTENSIVE
LOW CLOUDS AND LOCAL FOG COVERS THE NORTHWEST DESERT BASINS AND
MUCH OF THE WASATCH FRONT. OCCASIONAL SNOW FLURRIES COULD FALL OUT
OF THESE CLOUDS AND MAY BRING JUST ENOUGH ACCUMULATION TO MAKE
ROADS AND BRIDGES LOCALLY SLICK.
POCKETS OF FOG HAVE ALSO FORMED IN THE CACHE VALLEY AND MAY DEVELOP
IN SOME OF THE CENTRAL AND EASTERN VALLEYS AS WELL. SOME OF THE
FOG COULD BE LOCALLY DENSE.
THE LOW CLOUDS AND FOG SHOULD MOSTLY BURN OFF AFTER NOON BUT COULD
LOCALLY PERSIST INTO THE AFTERNOON...ESPECIALLY ACROSS THE
NORTHWEST DESERTS.
CLOUDINESS WILL INCREASE ACROSS THE OUTLOOK AREA FROM THE
SOUTHWEST TODAY THROUGH TONIGHT. THESE CLOUDS SHOULD HINDER THE
REDEVELOPMENT OF LOW CLOUDS AND FOG TONIGHT...AND COULD ALSO BRING
SOME LIGHT SNOW TO SOUTHERN AND EAST CENTRAL UTAH AFTER MIDNIGHT.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY
LIGHT SNOW IS POSSIBLE ACROSS MUCH OF THE OUTLOOK AREA ON TUESDAY
BUT THE BEST CHANCE WILL BE ACROSS NORTHERN AND CENTRAL PORTIONS.
ALTHOUGH ANY ACCUMULATION IS EXPECTED TO REMAIN LIGHT...EVEN A
SMALL AMOUNT OF SNOW ON THE COLD ROADS COULD MAKE TRAVEL
HAZARDOUS.
A STRONGER SYSTEM IS FORECAST TO CROSS THE CWA ON WEDNESDAY WITH A
BETTER CHANCE OF ACCUMULATING SNOW IN ALL AREAS EXCEPT DIXIE.
SIGNIFICANT ACCUMULATION IS POSSIBLE IN THE NORTHERN MOUNTAINS.
HIGH PRESSURE WILL RETURN TO THE OUTLOOK AREA ON THURSDAY BUT SOME
MOISTURE MAY LINGER ACROSS THE NORTH THURSDAY AND FRIDAY ALONG
WITH A SMALL THREAT OF SNOW.
