The radar

The Salt Lake City radar (KMTX), 163 km from the middle of the area, began a volume at 23:51 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

Elko, NV (KLKN), launched 12:00Z, 11.8 hours before the alert went out and 81 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.

What 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, 2 hours 14 minutes earlier.

Area forecast discussion, Jun 12, 3:36 PM MDT, 2 hours 14 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.

&&

UT...None.
WY...None.
