AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1015 PM MDT TUE AUG 26 2014

.SYNOPSIS...AN UPPER LOW WILL BE CROSS CENTRAL UTAH TONIGHT AND
EARLY WEDNESDAY. A DRIER AIRMASS WILL MOVE INTO THE AREA FROM THE
WEST THURSDAY AND FRIDAY.

&&

.DISCUSSION...AN UPPER LEVEL LOW CURRENTLY CENTERED OVER WEST-
CENTRAL AND SOUTHWEST UTAH THIS EVENING WILL CONTINUE TO SLOWLY
TRACK EAST-NORTHEAST ACROSS THE STATE TONIGHT INTO TOMORROW. A MOIST
AND SOMEWHAT UNSTABLE AIRMASS IS IN PLACE WHICH ALLOWED SHOWERS AND
THUNDERSTORMS TO DEVELOP ACROSS A LARGE PORTION OF THE FORECAST AREA
TODAY. FORCED ASCENT AHEAD OF THE LOW IS ALSO A MAJOR CONTRIBUTOR IN
KEEPING SOME STORMS ACTIVE...WITH THE STRONGEST STORMS AT THIS TIME
CLUSTERED OVER SOUTHWEST UTAH.

EXPECT STORMS TO WANE FROM WEST TO EAST ACROSS SOUTHERN UTAH BEHIND
THE LOW OVERNIGHT. THE FLASH FLOOD WATCH SHOULD BE SAFE TO EXPIRE AT
11PM SINCE THE FLOOD THREAT WILL GRADUALLY DIMINISH LATE TONIGHT.
ACROSS NORTHERN UTAH...RADAR TRENDS ARE CURRENTLY SHOWING SHOWERS
PUSHING WEST THIS EVENING WITH LITTLE ACTIVITY OVER THE UINTAS AND
SOUTHWEST WYOMING. HOWEVER...AS MOISTURE WRAPS AROUND THE
LOW...EXPECT PRECIPITATION TO ROTATE INTO NORTHEAST UTAH AND
SOUTHWEST WYOMING LATE TONIGHT WHILE SHOWERS WANE ACROSS FAR
NORTHWEST UTAH. THESE SHOWERS IN THE WRAPAROUND MOISTURE WILL
CONTINUE TO LINGER OVER THE MOUNTAINS AND EAST THROUGH TOMORROW
BEFORE TAPERING OFF OVERNIGHT.

MADE MINOR UPDATES MOSTLY TO ADJUST LATE EVENING POPS.

&&

.AVIATION...SURFACE WINDS AT THE SALT LAKE TERMINAL WILL REMAIN
PRIMARILY SOUTH THROUGH THE TAF PERIOD. ISOLATED SHOWERS AND
THUNDERSTORMS WILL LIKELY CREATE PERIODS OF GUSTY AND ERRATIC
OUTFLOW WINDS THROUGH THE EVENING AND EARLY MORNING HOURS. WITH THIS
ACTIVITY...THERE IS A 10 PERCENT CHANCE THAT BRIEF PERIODS OF MVFR
CONDITIONS WILL OCCUR WITH THESE STORMS.

&&


.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FLASH FLOOD WATCH UNTIL 11 PM MDT THIS EVENING FOR UTZ013-020-
     021.
