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.

.DISCUSSION...
LATEST SATELLITE/RADAR IMAGERY SHOWING SCATTERED CONVECTIVE FIRING
ACROSS THE CNTRL IDAHO MOUNTAINS AND NE NEVADA THIS AFTERNOON.
WATER VAPOR SATELLITE IMAGERY CONTINUED TO SHOW A BAGGY TROUGH
ALONG THE CALIFORNIA COAST WHILE A RIDGE EXTENDED NW FROM NEW MEXICO
INTO CNTRL IDAHO.  SHORT-WAVE ENERGY LIFTING NORTH THROUGH THE GREAT
BASIN APPEARED TO BE WELL INITIALIZED BY THE 12Z MODELS.  THE FIRST
WAVE NOTED NORTH OF BOISE WAS HELPING TO INITIATE AN AREA OF STRONG
CONVECTION NW OF MCCALL AND SHOULD HELP TO PROMOTE DEEPER CONVECTION
ACROSS THE CNTRL MOUNTAINS AS IT LIFTS FURTHER ENE TOWARD MISSOULA
THIS AFTERNOON/EVENING.  PRECIPITABLE WATER LEVELS WERE RUNNING
CLOSE TO AN INCH ON THE BOISE SOUNDING THIS MORNING AND HAVE ADDED
HEAVY SHOWERS TO CONVECTIVE WORDING IN THE CNTRL MOUNTAINS THIS
EVENING. THE SECOND WAVE OF CONCERN WAS LIFTING NORTH THROUGH ERN
NEVADA WITH AN ASSOCIATED 300MB 40KT JET SEGMENT SPARKING CONVECTION
ACROSS NE NEVADA.  THE 18Z MESO-ETA DRIVES THIS WAVE NORTH TO THE
IDAHO BORDER AROUND 03Z THIS EVENING WITH CONVECTION SPREADING INTO
THE SRN HIGHLANDS.  THE STRONGEST CONVECTION SHOULD DEVELOP ACROSS
SRN OREGON UNDER BEST DYNAMICAL SUPPORT HOWEVER THE POTENTIAL FOR
ISOLATED SEVERE STORMS IS POSSIBLE ACROSS THE SRN ZONES ALONG
PERIPHERY OF SHEARED ENVIRONMENT.  CONVECTION GENERALLY EXPECTED TO
DIMINISH LATE TONIGHT AS LOSS OF SURFACE HEATING IMPACTS STABILITY
HOWEVER PASSING SHORT-WAVE ENERGY MAY HELP TO SUSTAIN ISOLATED CELLS
THROUGH THE NIGHT. ADDITIONAL SHORT-WAVE ENERGY IS EXPECTED TO LIFT
NORTH THROUGH THE FORECAST AREA TUESDAY SUPPORTING YET ANOTHER ROUND
OF CONVECTION ACROSS SE IDAHO.  AVN CONTINUES TO ADVERTISE DRIER
CONDITIONS WORKING INTO REGION WEDNESDAY AND HAVE STAYED WITH THE
IDEA OF DRIER CONDITIONS ACROSS THE SRN ZONES AND SLIGHT CHANCE POPS
ACROSS THE NRN ZONES WEDNESDAY THROUGH FRIDAY.  AVN THEN ADVERTISING
GULF OF ALASKA LOW SHIFTING WEST AND BREAKING INTO SW CANADA MARKING
THE START OF WHAT APPEARS TO BE A PATTERN CHANGE SUNDAY WITH WNW
FLOW SPREADING ACROSS IDAHO AS EARLY AS MONDAY. HUSTON
