AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
931 PM MDT MON SEP 15 2014

.SYNOPSIS...HIGH PRESSURE WILL STRENGTHEN ACROSS THE INTERIOR WEST
THROUGH WEDNESDAY. TROPICAL MOISTURE WILL SPREAD INTO SOUTHERN
UTAH WEDNESDAY NIGHT AND WILL COVER THE ENTIRE AREA BY THURSDAY.

&&

.DISCUSSION...WARM RIDGE CONDITIONS CONTINUE OVER THE CWA THIS
EVE. THERE WAS JUST ENOUGH MOISTURE AND INSTABILITY TO GENERATE
ISOLATED CONVECTION DURING THE AFTN OVER THE HIGHER TERRAIN FROM
THE UINTAS S INTO THE SRN MTNS. CONVECTION ALSO FORMED ALONG THE
NV BORDER OF WEST CENTRAL AND SWRN UT AND THIS DRIFTED EAST ACROSS
CENTRAL UT INTO THE EVE WHERE IT HAS JUST ABOUT DISSIPATED. SOME
ADDITIONAL WEAK ISOLATED CONVECTION REMAINS ACTIVE ALONG THE NV
BORDER BETWEEN ABOUT WENDOVER AND ELY AND COULD CROSS NRN UT
OVERNIGHT BUT NOTHING OF ANY SUBSTANCE IS EXPECTED OUT OF THIS.

THE WARM RIDGE WILL REMAIN IN PLACE TUE THRU WED WITH ISOLATED
MAINLY MTN CONVECTION AND ABV NORMAL TEMPS.

LATEST GUIDANCE REMAINS ON TRACK TO SEND PERIPHERAL TROPICAL
MOISTURE FROM ODILE INTO THE CWA STARTING WED NIGHT LINGERING INTO
FRI. STILL LOOKS LIKE THE HEAVY RAIN AND FLASH FLOOD THREAT IS NOT
THAT HIGH BUT LOCAL INCIDENTS WILL BE POSSIBLE...AS THE DEEPEST
MOISTURE PASSES TO OUR SOUTH.

GUIDANCE ALSO CONTINUES TO REALLY STRUGGLE ON THE POSITION AND
EVOLUTION OF THE CLOSED LOW THAT GETS LEFT BEHIND AND CONFIDENCE
REMAINS QUITE LOW IN THE FORECAST AFTER FRIDAY.

NO CHANGES PLANNED AT THIS TIME.

&&

.AVIATION...VFR CONDITIONS WILL CONTINUE AT THE KSLC TERMINAL
THROUGH THE TAF PERIOD. SOUTHEAST WINDS WILL PREVAIL THROUGH
TUESDAY MORNING.

&&

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