AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
911 PM MST TUE FEB 24 2015

.SYNOPSIS...A COUPLE OF WEAK WEATHER DISTURBANCES WILL CROSS THE
REGION TONIGHT THROUGH THURSDAY. A SLOW MOVING STORM SYSTEM WILL
AFFECT THE REGION FRIDAY THROUGH THE WEEKEND.

&&

.DISCUSSION...A WEAK SHORT WAVE RIDGE IS OVER THE CWA THIS EVE
THAT WILL SHIFT RAPIDLY OUT OF THE CWA BY TOMORROW MORNING AS THE
FIRST OF A SERIES OF GRAZING SHORT WAVES PASSES TO OUR NORTHEAST.

TEMPS WARMED BACK UP TO NEAR OR ABOVE NORMAL ACROSS THE NRN AND
CENTRAL CWA TODAY THE BUT REMAINED BELOW NORMAL ACROSS THE SNOW
COVERED VALLEYS OF THE SOUTH. THE AIRMASS COOLS A LITTLE TOMORROW
FROM THE PASSING WAVE BUT INCREASED WINDS AND BETTER MIXING
SHOULD RESULT IN HIGHS SIMILAR TO TODAY IN AREAS WITH NO SNOW AND
SOME WARMING WHERE THERE IS.

A FEW HIGH CLOUDS ARE STARTING TO CROSS THE NRN CWA AND EXPECT AN
INCREASE OVERNIGHT AS THE WAVE NEARS. SOME LOWER CLOUD IS
SPREADING INTO THE FAR NERN CWA AND THIS SHOULD PERSIST INTO WED
BRINGING A SLIGHT CHANCE OF SNOW.

THE CHANCE OF FOG TONIGHT APPEARS SMALL AS THE LOW LEVELS HAD A
CHANCE TO DRY OUT SOMEWHAT TODAY BUT PATCHY GROUND FOG IS POSSIBLE
IN THE AREAS WITH SNOW COVER AS SKIES WILL REMAIN MOSTLY CLEAR
THERE AND TEMPS SHOULD GET FAIRLY COLD.

ADDITIONAL WEAK WAVES KEEP CARVING THE LARGE SCALE TROF WWD INTO
THE CWA THRU WED. THE NEXT BETTER DEFINED WAVE ARRIVES THU
MORNING DEEPENING THE TROF EVEN MORE AND BRINGING ENOUGH MOISTURE
TO GENERATE A LITTLE LIGHT SNOW ACROSS THE NRN AND CENTRAL MTNS
POSSIBLY GETTING TRACE AMOUNTS DOWN INTO THE NRN VALLEYS.

ADDITIONAL WAVES DEEPEN THE TROF ACROSS THE PACNW AND NRN ROCKIES
FRI AND THIS THEN SAGS INTO THE GREAT BASIN OVER THE WEEKEND
EVENTUALLY CLOSING OFF INTO A LOW.

UPDATED FORECASTS EARLIER TO REDUCE SKY COVER FOR THIS EVE AND
MADE SOME ADJUSTMENTS TO WINDS THRU THE NIGHT. NO ADDITIONAL
UPDATES PLANNED.

&&

.AVIATION...VFR CONDITIONS WITH LIGHT SOUTH WINDS WILL PREVAIL AT
KSLC THROUGH THE NIGHT.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
