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 00:00Z, 2.6 hours before the alert went out and 13 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 3, 4:23 PM MDT, 4 hours 15 minutes earlier.

Area forecast discussion, Jun 3, 4:23 PM MDT, 4 hours 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
423 PM MDT WED JUN 3 2015

.SYNOPSIS...A PROGRESSIVE SHORT WAVE WILL CONTINUE TO MOVE
THROUGH NORTHERN UTAH THIS EVENING. A CLOSED LOW OFF THE
CALIFORNIA COAST WILL BEGIN TO SEND MOISTURE NORTH INTO UTAH ON
FRIDAY...CONTINUING INTO THE WEEKEND.

&&

.SHORT TERM (THROUGH 06Z FRIDAY)...A BROAD AND FAIRLY DIFFUSE UPPER
LEVEL TROUGH RESIDES ACROSS THE WESTERN CONUS THIS AFTERNOON...WITH
A SERIES OF EMBEDDED SHORTWAVE FEATURES ROTATING THROUGH THE
ASSOCIATED CYCLONIC FLOW. ONE SUCH WAVE IS CURRENTLY WORKING ITS WAY
ACROSS NORTHEAST NV...WITH THE ENTRANCE REGION OF THE ATTENDANT JET
EXTENDING ACROSS NORTHERN UT. MEANWHILE A RESIDUAL FRONTAL BOUNDARY
RESIDES ACROSS CENTRAL UT THIS AFTERNOON...SERVING AS A DEMARCATION
ZONE BETWEEN A VERY DRY AIRMASS TO THE SOUTH...AND A SLIGHTLY COOLER
AND MORE MOIST AIRMASS ACROSS NORTHERN UT. THIS MODEST MOISTURE
COUPLED WITH DAYTIME HEATING HAS RESULTED IN SURFACE BASED
INSTABILITY ACROSS NORTHERN UT...AND WHEN COUPLED WITH DEEP LAYER
SHEAR VALUES NEAR 30 KTS WILL SUPPORT A CHANCE OF ORGANIZED
CONVECTION THROUGH THIS EVENING. HI-RES MODEL GUIDANCE HAS BEEN
FAIRLY CONSISTENT IN DEPICTING TWO AREAS OF DEVELOPMENT WHICH WOULD
IMPACT THE CWA...ONE ACROSS THE NORTHERN WASATCH THIS AFTERNOON
WHICH IS CURRENTLY ONGOING...AND THE SECOND ACROSS NORTHWEST UT THIS
EVENING AS ONGOING CONVECTION ACROSS NORTHEAST NV SPREADS EASTWARD.
STRONG GUSTY WINDS WILL BE POSSIBLE...PARTICULARLY WITH THIS
SECONDARY AREA MOVING OUT OF NV.

THE NEXT UPSTREAM WAVE CURRENTLY ALONG THE PACIFIC COAST IS FORECAST
TO CLOSE OFF AS IT SLIDES SOUTHWARD ALONG THE COAST THURSDAY. THIS
WILL ACT TO BACK THE FLOW ACROSS THE FORECAST AREA...ALLOWING THE
VERY DRY AIRMASS ACROSS SOUTHERN UT TO SPREAD NORTHWARD. LINGERING
MOISTURE ALONG THE ID BORDER REGION WILL MAINTAIN A SMALL THREAT OF
HIGH BASED CONVECTION ALONG THE TERRAIN...OTHERWISE THE REMAINDER OF
CWA SHOULD REMAIN DRY THURSDAY THROUGH THURSDAY EVENING.

.LONG TERM (AFTER 06Z FRIDAY)...SOUTHERLY PROGRESSION OF THE
AFOREMENTIONED CLOSED LOW WILL SLOW THURSDAY NIGHT INTO
FRIDAY...WITH MEAN POSITION OF UPPER LEVEL CIRCULATION CENTER
STAKING GROUND OVER SOCAL. GOOD AGREEMENT REMAINS IN GLOBALS
REGARDING FORMATION OF A SIGNIFICANT MOISTURE TAP FROM THE
TROPICAL EASTERN PACIFIC /REMNANT MOISTURE AND ENERGY FROM ANDRES/
INTO THE DESERT SOUTHWEST DURING THAT TIME. NAEFS MEAN PW
CONTINUES TO INDICATE VALUES SOME 2 TO 3 DEVIATIONS ABOVE NORMAL
WITH THIS TAP. BOTH EC/GFS INDICATE FORMATION OF A MODEST VORT
LOBE WITHIN ZONE OF INCREASED DIFFLUENCE ALOFT LATE THURSDAY NIGHT
THAT WILL TRACK SOUTH TO NORTH THROUGH THE EASTERN HALF OF THE
AREA FRIDAY...THIS AIDING INITIAL FORCING/LIFT/PRECIP WITH PASSAGE
DURING THE DAY. CONTINUED TO UP POPS TO LIKELY MOST ALL AREAS FROM
THE CENTRAL/SOUTHERN MOUNTAINS AND POINTS EAST AS SUCH.

WITH CENTER OF THE UPPER CIRCULATION REMAINING TO OUR SOUTH AND
WEST FRIDAY NIGHT...AND THE MID LEVEL DEFORMATION WELL TO OUR
NORTH AND WEST...DEEP LAYER MOISTURE WILL CONTINUE TO SPREAD NORTH
AND WEST ACROSS THE AREA WITH SOME WRAPPING BACK INTO THE LOW
INCREASING AREAL COVERAGE OF PRECIP INTO THE WEEKEND. FAVORABLE
UPPER JET DYNAMICS COUPLED WITH THE MID LEVEL CIRCULATION
TRANSITIONING NORTH INTO WESTERN UTAH WILL PROVIDE SUFFICIENT LIFT
FOR WIDESPREAD AND POTENTIALLY SIGNIFICANT PRECIP ACROSS MUCH OF
THE AREA SATURDAY. WITH CONTINUED NORTHEAST PROGRESSION OF THIS
CIRCULATION AND ELONGATION OF THE UPPER TROUGH EXPECTING THE
DEFORMATION TO SLIDE INTO NORTHERN UTAH SUNDAY FOCUSING A
CONTINUATION OF SHOWERS ACROSS THE NORTH...WITH A NOTABLE DRY
SLOT PUNCHING INTO THE SOUTHERN HALF OF THE STATE AS THE PRIMARY
MOISTURE PLUME SHIFTS SOUTH AND EAST OF THE AREA. AFOREMENTIONED
DEFORMATION NOW LOOKS TO DECAY ACROSS THE NORTH MONDAY ALLOWING A
CONTINUED DOWNWARD TREND IN POPS.

BOTTOM LINE...SUBSTANTIAL RAINFALL IS EXPECTED ACROSS NAMELY EAST
CENTRAL/SOUTHERN UTAH PERIODICALLY FRIDAY THROUGH SATURDAY.
EXPECTING THE POTENTIAL OF FLASH FLOODING OF NORMALLY DRY WASHES
AND SLOTS TO INCREASE DURING THAT TIME. CONTINUE TO CHECK LATEST
FORECAST DETAILS AND FUTURE FORECASTS DUE TO THE ANOMOLOUS NATURE
OF THIS EVENT.

&&

.AVIATION...THE PRIMARY FORECAST CHALLENGE FOR THE KSLC TERMINAL
FOCUSES ON GUSTY OUTFLOW WIND/MICROBURST POTENTIAL LATE THIS
AFTERNOON AND EVENING. THUNDERSTORMS HAVE DEVELOPED OVER EASTERN
NEVADA THIS AFTERNOON AND WILL CONTINUE TO MOVE INTO THEN ACROSS
THE WEST DESERT THIS EVENING. WINDOW OF STRONG AND GUSTY
WEST/NORTHWEST WINDS AND A 10 PERCENT CHANCE OF LIGHTNING IMPACT
WILL BE GREATEST DURING THE 00Z- 04Z TIMEFRAME AS THESE STORMS OR
THEIR REMNANTS MOVE THROUGH.

&&

.FIRE WEATHER...DRY SOUTHERLY FLOW WILL PREVAIL ACROSS CENTRAL AND
SOUTHERN UTAH THROUGH TONIGHT. LINGERING MOISTURE ACROSS NORTHERN
UTAH WILL MAINTAIN A THREAT OF SHOWERS AND THUNDERSTORMS THROUGH THE
EVENING. A LOW PRESSURE SYSTEM MOVING SOUTH ALONG THE CALIFORNIA
COAST WILL ALLOW FOR A VERY DRY SOUTHERLY FLOW ACROSS THE AREA
THURSDAY WITH ONLY ISOLATED TERRAIN BASED THUNDERSTORMS NEAR THE
IDAHO BORDER. THIS LOW WILL TAP INTO MOISTURE FROM DYING HURRICANE
ANDRES AND SWEEP NORTHWARD INTO SOUTHERN UTAH LATE THURSDAY
NIGHT...AND ACROSS THE REMAINDER OF UTAH FRIDAY. LOCALLY HEAVY RAIN
IS POSSIBLE IN FAVORABLE UPSLOPE AREAS OF SOUTHERN AND EASTERN UTAH
FRIDAY THROUGH SATURDAY. DRIER WILL WORK ITS WAY INTO THE SOUTHWEST
CORNER OF UTAH SATURDAY EVENING AND GRADUALLY SPREADS NORTHWARD
SUNDAY.

&&

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