AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
855 PM MDT SAT OCT 31 2015

.SYNOPSIS...WARM DRY HIGH PRESSURE WILL PERSIST OVER THE AREA
THROUGH SUNDAY. A COLD PACIFIC STORM WILL MOVE INTO THE GREAT
BASIN ON MONDAY AND REMAIN OVER THE REGION THROUGH THE MIDDLE
PORTION OF THE WEEK.

&&

.DISCUSSION...A LOW AMPLITUDE RIDGE REMAINS CENTERED TO OUR WEST
THIS EVENING WITH PATCHY HIGH CLOUDS STREAMING THROUGH THE RIDGE
AND ACROSS THE NRN CWA. THE MILD AIRMASS UNDER THE RIDGE IS
KEEPING TEMPS ON THE WARM SIDE FOR HALLOWEEN EVE AND WINDS HAVE
DROPPED OFF.

EXPECT TEMPS TO STAY MILD OVERNIGHT AS THE RIDGE AXIS SHIFTS PAST
AND HIGH CLOUDS INCREASE OVER THE NORTH. THE REMAINS OF THE CLOSED
LOW ALONG THE COAST OF SWRN CANADA EJECT EWD ALONG THE CANADIAN
BORDER ON SUNDAY WITH THE ASSOCIATED FRONTAL BOUNDARY SAGGING INTO
NRN UT LATE IN THE DAY. DO NOT EXPECT MUCH IF ANY PRECIP WITH THIS
FEATURE BUT A FEW SHOWERS COULD DEVELOP ALONG THE ID BORDER
ESPECIALLY AFTER 00Z.

A DEEP TROF DIGS DOWN THE WEST COAST SUN NIGHT BACKING THE FLOW
OVER UT TO MORE SOUTHERLY AND PREVENTING THE WEAK FRONT FROM
ADVANCING ANY FARTHER INTO THE STATE. THE GFS RENEWS THE EWD
MOTION OF THE FRONT AS THE MAIN UPPER TROF ADVANCES INTO THE GREAT
BASIN MON AFTN WHILE THE NAM AND EC ARE SLOWER HOLDING THE FRONT
WEST OF SLC UNTIL MON NIGHT AND HOLDING THE PRECIP OFF EVEN
LONGER.

SO CONFIDENCE IS NOT HIGH ON THREAT OF PRECIP THROUGH MON BUT
INCREASES SIGNIFICANTLY FOR TUE ONCE THE TROF BECOMES ESTABLISHED
OVER THE GREAT BASIN.

THIS SYSTEM IS STILL FORECAST TO BE COLD ENOUGH TO BRING A THREAT
OF SNOW ON THE BENCHES OR EVEN LOWER TUE NIGHT THROUGH WED.

NO UPDATES PLANNED AT THIS TIME.

&&

.AVIATION...WINDS WILL REMAIN SOUTHERLY AT THE KSLC TERMINAL
THROUGH THE NIGHT AND MOST OF THE DAY SUNDAY. WINDS COULD BECOME
GUSTY AFTER 15-16Z. ANY CIGS WILL REMAIN WELL ABOVE 7000 FT AGL.

&&

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