AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1032 AM MDT TUE JUL 15 2014

.SYNOPSIS...THE SOUTHERN END OF A TROUGH MOVING THROUGH THE
NORTHERN ROCKIES WILL INTERACT WITH MONSOON MOISTURE OVER CENTRAL
AND SOUTHERN UTAH TODAY. A GENERALLY DRIER NORTHWEST FLOW WILL
BECOME ESTABLISHED OVER MOST OF THE AREA WEDNESDAY AND THURSDAY.

&&

.DISCUSSION...MORNING SURFACE ANALYSIS INDICATES A FAIRLY WEAK
BOUNDARY IS CURRENTLY LOCATED FROM ROUGHLY WENDOVER TO NORTH OF
OGDEN. THIS BOUNDARY IS FORECAST BY A MAJORITY OF AVAILABLE MODEL
GUIDANCE TO SLOWLY MOVE SOUTHWARD THROUGH EARLY
AFTERNOON...REACHING THE JUAB/TOOELE COUNTY LINE EAST TO NEAR
PROVO BY MID AFTERNOON.

IN THE WAKE OF THIS BOUNDARY ACROSS THE NORTH...EXPECT ENOUGH
STABILITY TO KEEP THE THREAT OF THUNDERSTORMS MINIMAL. SOUTH OF
THIS BOUNDARY...DEEP MOISTURE SHOULD ALLOW FOR THE DEVELOPMENT OF
SHOWERS AND THUNDERSTORMS. THE BOUNDARY MAY SERVE AS A FOCUS TO
ALLOW FOR STRONGER/DEEPER CONVECTION TO DEVELOP ACROSS CENTRAL
PORTIONS OF THE STATE. GIVEN THE DEEP MOISTURE AND LIMITED
STEERING FLOW...EXPECT ANY THUNDERSTORMS WILL BE CAPABLE OF VERY
HEAVY RAIN. THIS LACK OF STEERING FLOW MAY LIMIT THE SCOPE OF
FLASH FLOODING HOWEVER IN ASSOCIATION WITH WEAK SHEAR AS CONVECTION
MAY QUICKLY DEVELOP AND THEN COLLAPSE...LIMITING THE ABILITY FOR
ANY ORGANIZATION AND THE ATTENDANT FLASH FLOODING THREAT.

WITH THE POSSIBILITY OF VERY HEAVY RAINFALL...A FLASH FLOOD WATCH
REMAINS IN EFFECT FOR CENTRAL AND SOUTHERN UTAH. THE MOST
CONCERNING LOCATIONS FOR FLASH FLOODING INCLUDE DRY WASHES...SLOT
CANYONS AND SMALL STREAMS IN STEEP TERRAIN AS WELL AS POSSIBLE
DEBRIS FLOWS NEAR RECENT BURN SCARS.

CURRENT FORECAST IS ON TRACK AND NO UPDATES ARE ANTICIPATED.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGHOUT THE
TAF PERIOD. WINDS ARE EXPECTED TO SHIFT TO WEST NORTHWEST BETWEEN 17
AND 18Z WITH A 30 PERCENT CHANCE OF OCCURRING AFTER 18Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FLASH FLOOD WATCH UNTIL 10 PM MDT THIS EVENING FOR UTZ010-012-
     013-019>021-517-518.
