Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Salt Lake City I, UT (KSLC), launched 12:00Z, 10.9 hours before the alert went out and 76 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
342 PM MDT TUE JUN 10 2014
.SYNOPSIS...A WEAK DISTURBANCE OFF THE SOUTHERN CALIFORNIA COAST
WILL CROSS THE DESERT SOUTHWEST THROUGH WEDNESDAY. HIGH PRESSURE
WILL RETURN MIDWEEK WITH ANOTHER TROUGH IMPACTING THE AREA LATE IN
THE WEEK.
&&
.SHORT TERM (THROUGH 06Z FRIDAY)...ELEVATED MOISTURE STREAMING IN
FROM THE SOUTHWEST FROM A WEAK UPPER LOW OVER SOCAL IS CONVERGING
OVER CENTRAL UTAH AS A MORE PROGRESSIVE WAVE RACES THROUGH THE THE
NORTHERN ROCKIES STATES. A WEAK FRONTAL BOUNDARY FROM THE LATTER
IS GRADUALLY PUSHING SOUTH INTO CENTRAL UTAH PROVIDING ADDITIONAL
FOCUS FOR ISOLATED HIGH BASED SHOWERS AND STORMS THIS AFTERNOON.
HAVE SEEN ISOLATED MICROBURST WINDS IN THE 50 TO 73 MPH FROM THE
MORE DEVELOPED CELLS OVER THE WEST DESERT BUT THUS FAR THESE HAVE
REMAINED OVER THE UNPOPULATED AREAS. CAN NOT RULE OUT SIMILAR
CELLS AND OUTCOME ACROSS CENTRAL UTAH THROUGH THIS EVENING.
THE AFOREMENTIONED FRONTAL BOUNDARY WILL CONTINUE TO PUSH SOUTH
OVERNIGHT...THIS AS THE REMNANT AND TRANSITIONING SOCAL WAVE OPENS
UP TRACKING INLAND. WEAK DYNAMIC LIFT FROM THIS AND THE CONTINUED
FOCUSING OF MID LEVEL MOISTURE DOES LOOK TO KEEP A FEW ISOLATED
NOCTURNAL SHOWERS GOING THROUGH THE NIGHT ON INTO TOMORROW MORNING
ACROSS MAINLY THE SOUTH. DRIER AND MORE STABLE AIR BEHIND THE FRONT
WILL BE ACROSS MUCH OF THE AREA COME TOMORROW...BUT THE SOUTH WILL
REMAIN IN THE VICINITY OF THE FRONTAL CONVERGENCE AIDING AFTERNOON
CONVECTION ONCE AGAIN.
THURSDAY INTO THE NIGHT...A DEEPER PACNW TROUGH WILL CARVE INTO
OREGON/IDAHO TIGHTENING A SOUTHERLY MSLP GRADIENT ACROSS THE WESTERN
VALLEYS. EXPECTING GUSTY CONDITIONS IN THE PREFRONTAL ENVIRONMENT
AND ANOTHER ROUND OF AFTERNOON/EVENING STORMS IN THE NORTH AS THE
FRONT APPROACHES FAR NORTHWESTERN UTAH LATE DAY.
&&
.LONG TERM (AFTER 06Z FRIDAY)...THE LONG TERM FORECAST BEGINS WITH
A TROUGH CROSSING THE NORTHERN INTERMOUNTAIN REGION. THE
ASSOCIATED COLD FRONT WILL SLOWLY CROSS THE STATE
FRIDAY...BRINGING MUCH COOLER TEMPERATURES TO MOST LOCATIONS
SATURDAY. SATURDAYS HIGHS LOOK TO BE ABOUT 5-10 DEGREES BELOW
NORMAL. A SERIES OF WEAK TROUGHS WILL THEN CROSS THE NORTHERN
INTERMOUNTAIN REGION SUNDAY AND MONDAY. THESE DISTURBANCES WILL
HAVE LITTLE IMPACT TO MUCH OF THE CWA ASIDE FROM AN INCREASE IN
CLOUDS ACROSS NORTHERN UTAH AND PERHAPS A FEW
SHOWERS/THUNDERSTORMS ACROSS THE HIGHER TERRAIN. 12Z GFS/12Z EC
AND THE GFS ENSEMBLES SHOW LARGE AMOUNT OF MODEL TO MODEL
INCONSISTENCY AFTER MONDAY. CONFIDENCE IN THIS PORTION OF THE
FORECAST IS LOW. LEANED TOWARD THE GFS SOLUTION BUT EVEN THE GFS
ENSEMBLE MEMBERS FROM THE 00Z RUN SHOWED A LARGE AMOUNT OF SPREAD
IN SOLUTIONS.
&&
.AVIATION...THERE IS A 30 PERCENT CHANCE THAT SHOWERS OR
THUNDERSTORMS WILL IMPACT THE SLC TERMINAL BETWEEN 22Z AND
04Z...WITH GUSTY ERRATIC WINDS BEING THE MOST LIKELY IMPACT. AWAY
FROM SHOWERS...NORTHWESTERLY WINDS AND VFR CONDITIONS SHOULD PREVAIL
THROUGH AT LEAST 06Z. WHILE NORTHWESTERLIES ARE EXPECTED TO PERSIST
THROUGH THE OVERNIGHT HOURS...THERE IS A CHANCE OF LIGHT SOUTHERLY
WINDS BEGINNING BETWEEN 07Z AND 11Z.
&&
.FIRE WEATHER...TWO PRIMARY FIRE WEATHER CONCERNS TO NOTE THROUGH
THIS EVENING. FIRST OFF...GUSTY WINDS AND LOW RH...A FRONTAL
BOUNDARY DRAPED ACROSS CENTRAL UTAH AND MODERATE SOUTHWESTERLY
FLOW ALOFT HAS COMBINED WITH CURED FUELS AND BONE DRY RH TO
PRODUCE CRITICAL FIRE WEATHER CONDITIONS ACROSS ZONES 495-497. A
RED FLAG WARNING REMAINS IN EFFECT THROUGH THIS EVENING AS SUCH.
ADDITIONALLY...MID LEVEL MOISTURE HAS INCREASED ALONG A MID LEVEL
CONVERGENCE ZONE ACROSS CENTRAL AND NORTHERN UTAH AND ISOLATED
HIGH BASED SHOWERS AND STORMS HAVE FORMED IN THE VICINITY OF THE
FRONT. THE BULK IF NOT ALL OF THESE STORMS WILL REMAIN NORTH OF
THOSE AREAS WITH AFOREMENTIONED CURED FUELS HOWEVER...BUT SURFACE
HUMIDITY WILL REMAIN VERY LOW ALL AREAS. MICROBURST WINDS AND
LOCALIZED OUTFLOWS ARE LIKELY ACROSS THE CENTRAL PORTIONS WITH
THESE STORMS AS THEY TRACK WEST TO EAST ACROSS THE AREA. AS THE
FRONT PUSHES SOUTH TONIGHT A WEAK UPPER LEVEL FEATURE WILL PASS
OVERHEAD ALLOWING A FEW OF THESE GUSTY SHOWERS TO LINGER THROUGH
THE NIGHT.
A STRONGER STORM SYSTEM WILL CARVE INTO IDAHO/OREGON THURSDAY
THROUGH FRIDAY. A STRONGER COLD FRONT AHEAD OF THIS WILL APPROACH
THE DISTRICT THURSDAY WITH ELEVATED SOUTHERLY WINDS PRECEDING IT
ONCE AGAIN. THE FRONT WILL ENTER NORTHERN UTAH BY FRIDAY MORNING
SLOWLY PUSHING SOUTH...BUT ELEVATED SOUTHERLY WINDS AND LOW RH WILL
REMAIN IN PLACE ACROSS THE SOUTH. OPTED TO ISSUE A FIRE WEATHER
WATCH FROM THURSDAY MORNING THROUGH FRIDAY EVENING. ANOTHER ROUND OF
DRY THUNDERSTORMS WILL BE POSSIBLE ACROSS THE NORTH.
&&
