AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
941 AM MDT FRI AUG 1 2014

.SYNOPSIS...HIGH PRESSURE ALOFT WILL STRENGTHEN ACROSS THE
INTERIOR WEST OVER THE FIRST HALF OF THE UPCOMING WEEKEND. A
STRONGER AND SIGNIFICANTLY MOISTER WEATHER DISTURBANCE WILL LIFT
NORTH THROUGH THE GREAT BASIN AND IMPACT MUCH OF UTAH SUNDAY
THROUGH EARLY NEXT WEEK.


&&

.DISCUSSION...MOSTLY SUNNY SKIES EXIST ACROSS MOST OF UTAH AND
SOUTHWEST WYOMING THIS MORNING...WITH THE ONLY CLOUD COVER AND
CONVECTIVE ACTIVITY IN NORTHEASTERN UTAH...WHERE A LINGERING
DISTURBANCE IS INITIATING SOME LIGHT SHOWERS CENTERED AROUND THE
UINTA BASIN. WITH GENERALLY LESS DYNAMIC FORCING TODAY COMPARED TO
YESTERDAY...AS WELL AS A SLIGHTLY DRIER AIRMASS...SHOWERS AND
THUNDERSTORMS SHOULD BE LESS WIDESPREAD TODAY...WITH THE BEST
COVERAGE EXPECTED TO BE IN THE UINTAS AND ALONG THE HIGHER TERRAIN
OF CENTRAL UTAH. OTHERWISE...HIGH PRESSURE WILL BUILD OVER THE
REGION TODAY AND TOMORROW...LEADING TO THE WARMEST DAYS OF THE
WEEK IN MANY LOCATIONS.

THE SHORT PERIOD OF QUIETER WEATHER WILL COME TO AN ABRUPT END
SUNDAY AND MONDAY...AS A SHORTWAVE TROUGH MOVES INTO THE GREAT
BASIN FROM ARIZONA. THIS WAVE WILL BRING A SIGNIFICANT MOISTURE
SURGE WITH IT...AND PRECIPITABLE WATER VALUES ARE EXPECTED TO
INCREASE TO 1.1 TO 1.3 INCHES OVER MOST OF THE AREA BY SUNDAY
NIGHT. THIS SHOULD HELP INITIATE NUMEROUS SHOWERS AND
THUNDERSTORMS ACROSS THE SOUTHERN HALF OF UTAH ON SUNDAY...AND
THEN PRECIPITATION WILL FOCUS ON CENTRAL AND NORTHERN UTAH SUNDAY
NIGHT AND MONDAY.

ISSUED A MINOR UPDATE EARLIER...PRIMARILY TO INCREASE CLOUD COVER
ACROSS NORTHEAST UTAH. OTHERWISE THE FORECAST LOOKS TO BE IN GOOD
SHAPE...AND NO MORE CHANGES ARE EXPECTED FOR THIS MORNING.

&&

.AVIATION...WINDS AT THE SLC TERMINAL ARE EXPECTED TO SWITCH TO
THE NORTHWEST BETWEEN 17Z AND 19Z...WITH A SLIGHT CHANCE THAT
SOUTHERLIES PERSIST AS LATE AS 20Z. THERE IS A 10 PERCENT CHANCE
OF THUNDERSTORMS IMPACTING THE TERMINAL THIS AFTERNOON...BUT MOST
OF THE ACTIVITY SHOULD REMAIN SOUTH AND EAST OF THE TERMINAL.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
