AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1009 AM MDT SUN AUG 30 2015

.SYNOPSIS...A COLD FRONT WILL SLIDE SOUTHEAST INTO CENTRAL UTAH BY
EARLY AFTERNOON BEFORE WEAKENING. WITH THE REGION BETWEEN A RIDGE
OF HIGH PRESSURE FROM THE UPPER MIDWEST TO THE SOUTHERN PLAINS AND
A TROUGH OF LOW PRESSURE OVER THE PACIFIC NORTHWEST...A GENERALLY
DRY SOUTHWEST FLOW WILL PREVAIL FOR MOST OF THE WORKWEEK.

&&

.DISCUSSION...COLD FRONT IS NEAR A KTPH-KFWZ LINE THIS MORNING AND
WILL CONTINUE SOUTHEAST DURING THE DAY AS IT WEAKENS. CLOUDS
REMAIN IN PLACE PRIMARILY ALONG AND BEHIND THE BOUNDARY...BUT
EARLIER SHOWERS HAVE MOSTLY DISSIPATED. THE ASSOCIATED UPPER
TROUGH WILL JUST MISS UTAH AS IT MOVES ACROSS IDAHO AND MONTANA
TODAY...BUT THIS WILL SHIFT THE BEST JET SUPPORT OVER THE AREA
EASTWARD. WITH THESE FACTORS IN MIND...EXPECTING SCATTERED CONVECTION
TO DEVELOP OVER EASTERN UTAH THIS AFTERNOON INTO THE EARLY
EVENING. OTHERWISE...LOOKING AT NOTICEABLY COOLER TEMPERATURES
BEHIND THE FRONT WITH THE BEST COOLING OVER NORTHERN UTAH WHERE
MAXES SHOULD BE IN EXCESS OF 10F BELOW VALUES OBSERVED YESTERDAY.

THE TROUGH WILL MOVE INTO THE CENTRAL UNITED STATES
TONIGHT...ALLOWING A DRIER AND MORE STABLE SOUTHWEST FLOW TO MOVE
INTO THE FORECAST AREA BEGINNING TONIGHT. A SLOW WARMING TREND
WILL MOVE MAXES TO OR SLIGHTLY ABOVE SEASONAL NORMALS BY TUESDAY.
LINGERING MOISTURE WILL ALLOW FOR A FEW STORMS OVER THE HIGHER
TERRAIN EACH AFTERNOON...PARTICULARLY OVER SOUTHERN UTAH. ANOTHER
APPROACHING PACIFIC NORTHWEST TROUGH WILL RESULT IN INCREASING
WINDS OVER THE FORECAST AREA FOR THE MIDDLE OF THE WEEK...WHICH
COULD INTRODUCE SOME FIRE WEATHER RELATED CONCERNS ALONG WITH SOME
COOLER TEMPERATURES AS THE UPCOMING WEEKEND APPROACHES.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...NORTHWEST SURFACE WINDS ARE EXPECTED TO BECOME
MODERATELY GUSTY AT THE KSLC TERMINAL AFTER 18Z TODAY. OUTSIDE OF
THIS A SLIGHT CHANCE EXISTS THAT CONVECTIVE SHOWERS WILL PASS OVER
THE TERMINAL THROUGH 00Z THIS EVENING. VFR CONDITIONS WILL PREVAIL
WITH BROKEN MID LEVEL CLOUDS REMAINING WELL ABOVE 6000FT AGL.

&&

.FIRE WEATHER...A COLD FRONT OVER NORTHERN UTAH WILL CONTINUE TO
PUSH THROUGH THE REGION THROUGH THE DAY. THIS FRONT WILL HELP
PRODUCE SOME GUSTY WINDS ACROSS MUCH OF THE DISTRICT. EASTERN UTAH
WILL BE THE FOCUS AREA FOR SCATTERED SHOWERS AND THUNDERSTORMS
THIS AFTERNOON THROUGH THE EARLY EVENING. AFTER THE COLD FRONT
EXITS...A DRIER AND MORE STABLE AIRMASS WILL MOVE BACK IN FOR THE
EARLY PART OF THE UPCOMING WEEK. WITH ANOTHER TROUGH
APPROACHING...SOUTHWEST WINDS WILL BECOME GUSTY DURING THE MIDDLE
TO LATTER PART OF THE WORK WEEK. THIS MAY PRODUCE AREAS OF
CRITICAL FIRE WEATHER CONDITIONS WHERE FUELS ARE
DRY...PARTICULARLY OVER WESTERN UTAH.

&&

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