AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
912 PM MDT THU OCT 16 2014

.SYNOPSIS...HIGH PRESSURE WILL BUILD ACROSS THE INTERMOUNTAIN
REGION THROUGH FRIDAY. A WEAKENING STORM SYSTEM MOVING EAST
THROUGH THE WESTERN STATES WILL BRING SOME MOISTURE INTO SOUTHERN
UTAH THIS WEEKEND.

&&

.DISCUSSION...BUILDING HEIGHTS ACROSS THE INTERIOR THROUGH FRIDAY
WILL BE IN RESPONSE TO THE UPPER TROUGH ADVANCING EAST ACROSS THE
EASTERN PACIFIC. THIS TROUGH WILL BEGIN AN HARD SPLIT AS IT
REACHES THE WEST COAST LATE FRIDAY. THE NORTH SPLIT WILL REMAIN
WELL TO THE NORTH AS IT TRACKS EAST THROUGH SOUTHERN CANADA. THE
SOUTHERN SPLIT IS STILL PROGGED TO EVENTUALLY DEVELOP INTO A CLOSED
LOW ALONG THE ARIZONA/MEXICO BORDER LATE IN THE UPCOMING WEEKEND.

IMPACTS FROM THIS CLOSED LOW LOOK TO BE MINIMAL FOR EVEN THE
SOUTHERN TIER OF UTAH. THE BIGGEST NEGATIVE IS THAT THIS FEATURE
IS FAR REMOVED FROM THE FORECAST. DEEP LAYER MOISTURE WILL ALSO BE
AN ISSUE AS THE FLOW ALOFT TAKES ON A MORE EASTERLY COMPONENT
ACROSS NORTHERN ARIZONA LATE IN THE WEEKEND. CURRENT FORECAST MAY
BE JUST A BIT TOO AGGRESSIVE WITH THE POPS SUNDAY....BUT FOR NOW
WILL THEM AS IS IN THE CURRENT FORECAST PACKAGE.

NEXT THREAT FOR PRECIP WILL COME AROUND THE TUESDAY/WEDNESDAY
TIMEFRAME. THIS NEXT PACIFIC TROUGH DOES NOT LOOK LIKE IT WILL
SPLIT LIKE THE WEEKEND SYSTEM...BUT INSTEAD WILL LIFT MUCH OF THE
ENERGY NORTHEAST INTO THE NORTHERN ROCKIES/NORTHERN GREAT BASIN.

&&

.AVIATION...A DRY AND STABLE WESTERLY FLOW ALOFT WILL REMAIN
ACROSS THE  REGION THROUGHOUT THE TAF PERIOD. WINDS WILL REMAIN
LIGHT WITH A PREVAILING SOUTHEAST DIRECTION THROUGH FRIDAY
MORNING.

&&

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