.DISCUSSION...STABILITY TRENDS ACROSS THE REGION WILL INCREASE
RAPIDLY OVER THE NEXT 24 HOURS AS A STRONG WARM FRONT APPROACHES
FROM THE WEST THIS AFTERNOON AND EVENTUALLY PASSES THROUGH THE
STATE TONIGHT. THAT SAID...LOW LEVEL INSTABILITY REMAINS IN PLACE
ACROSS THE VALLEYS OF NORTHERN UTAH...AND NORTHERLY WINDS ARE
EXPECTED TO INCREASE JUST ENOUGH TO ALLOW SUFFICIENT MIXING
ALLOWING CLEARING INDICES TO RISE ABOVE 500 STARTING MIDDAY
TODAY. THE WINDOW OF ABOVE 500 WILL REMAIN LIMITED TO THE
AFTERNOON HOURS TODAY...AS LEVELS WILL LOWER WELL BELOW 500 BY
FRIDAY IN WAKE OF THE FRONT. PASSAGE OF THE WARM FRONT TONIGHT
WILL BRING ISOLATED SNOW SHOWERS TO NORTHERN UTAH...BUT THESE
SHOULD SUBSIDE BY EARLY FRIDAY AFTERNOON. HIGH PRESSURE WILL BUILD
THROUGH THE REGION OVER THE WEEKEND HINDERING CLEARING INDEX
RECOVERY.
