The radar
The Salt Lake City radar (KMTX), 117 km from the middle of the area, began a volume at 22:57 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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, 11.0 hours before the alert went out and 100 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.

CRKWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Salt Lake City, UT wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 12, 3:36 PM MDT, 1 hour 21 minutes earlier.
Area forecast discussion, Jun 12, 3:36 PM MDT, 1 hour 21 minutes before
Area Forecast Discussion National Weather Service Salt Lake City UT 336 PM MDT SUN JUN 12 2016 .SYNOPSIS...A cool upper trough will slowly cross the Great Basin today through Monday. Weak high pressure will follow briefly Monday night into Tuesday. A dry southwest flow is forecast to develop midweek, with strong high pressure moving back in for the upcoming weekend. && .SHORT TERM (Through 00Z Wednesday)...Water vapor loop shows a closed low approaching from southern California. AMDAR 400-200MB wind observations place a 75-125kt cyclonic jet along the west coast then northward from southern California over the western Great Basin and northern Rockies. GOES/HRRR/12Z KSLC RAOB indicate the precipitable water value ranges from 0.20"-0.30" southern mountains to 0.75-0.90" across the northwest and southeast valleys. With yesterday's cold front retreating northward into north central Utah this afternoon, warmer, drier and gusty south winds will be common south of this boundary. The boundary and proximity of the upper level jet will also aid in convective development across the north central areas. SREF indicates 30kts of effective shear is a lock with a good chance for 40kts. SPC Mesoscale Analysis page based off the RAP currently indicates 45-55kts of shear across west central Utah. Given the extra forcing mechanisms, despite our slimmer instability compared to east of the Rockies, we may still maintain a good balance for sustainment of updrafts. Have mentioned this risk for damaging winds (despite higher dewpoints) and large hail in the HWO. Convection gradually weakens this evening, but wont be ruling out isolated activity overnight with the trough approaching. This is the reason PoPs increase between late tonight and tomorrow morning, furthermore with diurnal heating during the afternoon. Not expecting nearly the threat for severe convection with a much lower probability of 30kts of effective shear. Convection though could potentially affect the entire region due to the arriving dynamics. Convection wanes Monday night with loss of heating and the passage of the trough axis. Could have enough moisture for isolated afternoon convection in the NE mountains Tuesday afternoon, and across NW Utah later in the day ahead of the next northern stream cold front. && .LONG TERM (After 00Z Wednesday)...A broad storm system is progged to dive south along the Pacific Northwest coast early next week before stalling just off the coast during the middle to latter part of the week. The location of the system will keep gusty southwest flow over much of the forecast area into Friday as the airmass dries and warms. Global models indicate that the system will finally move onshore Friday before tracking northeast through Oregon and Washington. As the system continues northward, the winds will tend to relax and building high pressure will allow the warming and drying trend to continue with maxes running in excess of 15F above seasonal norms by the upcoming weekend. && .HYDROLOGY...Recent spell of heat has led to a significant increase of high elevation snowmelt. Rises on streams and tributaries, especially those off the Uinta mountains have brought them to bankfull. Additional rainfall this weekend may further increase flows, though with temperatures cooling, snowmelt rates will decrease. Waterways will be running at bankfull, cold and fast this weekend, please keep children and pets away. && .AVIATION...VFR conditions are expected at KSLC through tonight. Northwest winds will switch back to the south between 03-04z. There is a 20 percent chance of a thunderstorm impacting the terminal through 04z with gusty erratic winds and lightning. && .FIRE WEATHER...Remnant moisture will provide for scattered to numerous showers and thunderstorms primarily across the northern two thirds of Utah through this evening. Lightning, and gusty/erratic winds are threats along with the potential for wetting rainfall. Gusty south winds and low RH will provide critical fire weather conditions to many southern Utah valleys this afternoon though fuels are deemed as not critical. Another round of activity across the entire state Monday as a strong disturbance passes through. Critical fire weather conditions may occur across the southeast valleys. A dry gusty southwest flow sets up midweek setting up a warming trend with much drier conditions developing across the region. && .SLC Watches/Warnings/Advisories... UT...None. WY...None. && SHORT TERM...Rogowski LONG TERM...Traphagan AVIATION...Seaman FIRE WEATHER...Rogowski HYDROLOGY...Rogowski For more information from NOAA's National Weather Service visit... http://weather.gov/saltlakecity For frequently asked questions about the Area Forecast Discussion visit... http://weather.gov/saltlakecity/general/afd_faqs.php
