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
Boise Airport, ID (KBOI), launched 12:00Z, 10.9 hours before the alert went out and 103 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, Jul 14, 2:31 PM MDT, 2 hours 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BOISE ID 231 PM MDT TUE JUL 14 2015 .SHORT TERM...TONIGHT THROUGH THURSDAY...UPPER LEVEL SHORT WAVE MOVING EAST ACROSS NRN NV IS HELPING CONVECTION DEVELOP OVER THE REGION. AS OF 220 PM MDT...THE MOST SIGNIFICANT AREAS WERE IN WRN BAKER COUNTY...OWYHEE COUNTY...AND ERN VALLEY COUNTY. SOME OF THE ACTIVITY OVER THE OWYHEES WILL LIKELY HEAD INTO THE TREASURE VALLEY...INCLUDING THE BOISE METRO AREA...AFTER 330 PM. WE EXPECT THE SHOWERS AND THUNDERSTORMS TO LAST WELL INTO THE EVENING AS THEY MOVE NORTHEAST AT 15 TO 20 MPH. THERE IS AN UPPER LEVEL TROUGH WEST OF THE AREA...THE SAME BASIC ENTITY THAT HAS BEEN THERE FOR THE PAST SEVERAL DAYS. THIS WILL MOVE EAST OVERNIGHT AND PASS OVER THE AREA EARLY TOMORROW. CONVECTION TOMORROW AFTERNOON AND EVENING WILL BE RESTRICTED TO OUR FAR ERN SECTIONS. AFTER TOMORROW EVENING...WE WILL BE DRY THE REMAINDER OF WED NIGHT AND ON THU AS DRIER ZONAL FLOW BECOMES ESTABLISHED. THE UPPER LEVEL FLOW WILL BECOME SLIGHTLY NORTH OF WEST LATE THU AS THE NEXT UPPER TROUGH TAKES AIM ON THE PAC NW. TEMPS WILL BE A FEW DEGREES BELOW NORMAL FOR DAYTIME HIGHS AND NEAR NORMAL AT NIGHT. GUSTY WINDS ARE EXPECTED NEAR SHOWERS AND THUNDERSTORMS. OTHERWISE NW WINDS WED AND THU AFTERNOON AND EVENING WILL BE A LITTLE STRONGER THAN THEY HAVE BEEN LATELY DUE TO THE INFLUENCE OF THE PASSING TROUGH AND THE ZONAL FLOW. .LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...UPPER LEVEL LOW POISED IN CENTRAL CANADA IS EXPECTED TO MOVE SLOWLY EAST...WITH A LOBE OF ENERGY BREAKING OFF AND MOVING OVER OUR AREA ON FRIDAY. CONFIDENCE IS GROWING THAT AN ASSOCIATED COLD FRONT WILL SLOWLY SWEEP THROUGH THE AREA SOMETIME FRIDAY AFTERNOON/EVENING. AS THAT ENERGY FORMS INTO A CUT-OFF LOW OVER NORTHERN CALIFORNIA...THE FRONT WILL LIKELY STALL OUT ALONG THE ID/NV BORDER. HOWEVER... CONFIDENCE IS LOW ON HOW MUCH MOISTURE THIS SYSTEM WILL BE ABLE TO TAP INTO...AND THE GFS IS SIGNIFICANTLY MORE MOIST THAN THE ECMWF. SO...FOR NOW...POPS ARE LOW DESPITE A CONFIDENT COLD FRONT PASSAGE...BUT TEMPERATURES WILL LIKELY BE COOLER...MAYBE 10 DEGREES BELOW NORMAL...FRIDAY AND SATURDAY. FOR SUNDAY AND BEYOND...MODELS DIVERGE QUITE SIGNIFICANTLY IN HOW TO HANDLE THE CUT-OFF LOW...THE NEXT UPPER LOW OFF OF THE BRITISH COLUMBIA COAST...AND THE PATH OF HURRICANE DOLORES. && .AVIATION...MOSTLY VFR WITH SHOWERS AND THUNDERSTORMS. VARIABLE GUSTY WINDS UP TO 45 KTS...AND MVFR/IFR CONDITIONS DUE TO HEAVY RAIN ARE ALL POSSIBLE WITH STRONGER THUNDERSTORMS THROUGH SUNSET. OTHERWISE...SURFACE WINDS GENERALLY 12 KTS OR LESS.
