AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1011 AM MDT TUE AUG 21 2012

.SYNOPSIS...A PACIFIC TROUGH WILL IMPACT THE GREAT BASIN BEGINNING
TODAY...WITH MOISTURE AND INSTABILITY LINGERING THROUGH THURSDAY.
DRIER AIR WILL MOVE INTO THE AREA BEGINNING FRIDAY.

&&

.DISCUSSION...A HIGH AMPLITUDE RIDGE REMAINS CENTERED OVER THE
INTERMOUNTAIN WEST THIS MORNING...WITH A FAIRLY DRY AIRMASS OVER
MUCH OF THE CWA. HOWEVER...THAT WILL CHANGE LATER TODAY AS A
TROUGH OFF THE WEST COAST CONTINUES TO MOVE INLAND. SOUTHWESTERLY
FLOW AHEAD OF THIS TROUGH WILL DRAW MOISTURE INTO WESTERN AND
SOUTHERN UTAH...AND THE NORTHERN BRANCH OF THIS TROUGH WILL HELP
TO INITIATE SHOWERS AND THUNDERSTORMS ACROSS WESTERN UTAH THIS
AFTERNOON AND EVENING. MANY OF THESE STORMS IN THE NORTHERN HALF
OF THE STATE WILL LIKELY START AS DRY THUNDERSTORMS PRODUCING
PRIMARILY GUSTY WINDS...BUT EXPECT MOISTURE TO MAKE ITS WAY DOWN
TO THE SURFACE MORE EASILY IN THE 03Z TO 06Z TIMEFRAME.

IN SOUTHERN UTAH...ENOUGH MOISTURE IS STILL IN PLACE THAT DIURNAL
CONVECTION IS EXPECTED TO FIRE THIS AFTERNOON OFF THE HIGHER
TERRAIN. ISOLATED FLASH FLOODING IS STILL POSSIBLE...BUT IN
GENERAL THE COVERAGE IS NOT EXPECTED TO BE ENOUGH TO MAKE THIS
FLOODING WIDESPREAD FOR TODAY. THAT COULD CHANGE TOMORROW AND
THURSDAY...AS DEEPER MOISTURE AND FORCING FROM A SOUTHERN CUT-OFF
LOW SHOULD HELP TO BRING WIDESPREAD PRECIPITATION TO THE AREA.

UPDATED THE FORECAST THIS MORNING TO ADD POPS TO FAR WESTERN
UTAH...WHERE SHOWERS WITH ISOLATED THUNDERSTORMS HAVE ALREADY
BEGUN THIS MORNING. NO FURTHER UPDATES ARE ANTICIPATED THIS
MORNING.

&&

.AVIATION...SURFACE WINDS AT THE SLC TERMINAL ARE EXPECTED TO
SWITCH TO THE NORTHWEST BETWEEN 18Z AND 20Z...WITH A SLIGHT CHANCE
THAT SOUTHERLIES PERSIST THROUGH 21Z. SHOWERS AND THUNDERSTORMS
WILL BEGIN MOVING INTO UTAH FROM THE WEST THIS AFTERNOON...AND IT
IS LIKELY THAT THESE STORMS WILL IMPACT THE TERMINAL BETWEEN 00Z
AND 06Z WEDNESDAY. LIGHTNING AND GUSTY WINDS ARE THE MOST LIKELY
IMPACTS.

&&

.FIRE WEATHER...SHOWERS AND THUNDERSTORMS WILL DEVELOP AGAIN THIS
AFTERNOON...WITH MORE WIDESPREAD COVERAGE THAN YESTERDAY. ACROSS
NORTHWEST AND WEST CENTRAL UTAH...WHERE LOW LEVELS ARE DRY...THESE
THUNDERSTORMS WILL BE MOSTLY DRY...BRINGING THE THREAT FOR NEW
FIRE STARTS. ADDITIONALLY...WINDS WILL BE GUSTY AND ERRATIC IN THE
VICINITY OF THESE DRY THUNDERSTORMS...POTENTIALLY RESULTING IN
ERRATIC FIRE BEHAVIOR. ACROSS SOUTHERN UTAH...MOISTURE IS DEEPER.
THUNDERSTORMS ACROSS SOUTHERN UTAH WILL BE ACCOMPANIED BY HEAVY
RAIN.

MOISTURE WILL REMAIN OVER THE STATE THROUGH THURSDAY. SHOWERS AND
THUNDERSTORMS ARE EXPECTED THROUGH THIS TIME PERIOD ACROSS ALL BUT
EXTREME NORTHERN UTAH.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
