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.

Area forecast discussion, Jul 4, 2:02 PM PDT, 6 hours 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPOKANE WA 202 PM PDT TUE JUL 4 2006 .SYNOPSIS...SOUTHERLY FLOW OVER THE REGION WILL BRING A THREAT OF THUNDERSTORMS TO THE AREA THROUGH THURSDAY. AS THE HIGH PRESSURE RIDGE MOVES TO THE EAST TEMPERATURES WILL COOL SLOWLY...BUT WILL REMAIN ABOVE AVERAGE FOR EARLY JULY. && .DISCUSSION... TONIGHT THROUGH THURSDAY NIGHT...SOUTHERLY FLOW CONTINUES OVER THE AREA. RIDGE AXIS TO OUR EAST CONTINUES TO MOVE VERY SLOWLY EAST. THIS ALLOWS FOR A GRADUAL COOLING AS WELL AS AN EASTWARD SHIFT OF THE JET AND ASSOCIATED INSTABILITY. THIS MORNINGS SHORT WAVE HAS EXITED THE AREA INTO BC LEAVING A FAIRLY MOIST ATMOSPHERE IN ITS WAKE. DEW POINTS IN THE MID 50S...INCLUDING THE HIGHER ELEVATIONS LIKE STAMPEDE PASS...ARE RESULTING IN CAPES IN THE 1500-2500 J/KG RANGE THIS AFTERNOON. LAPS ANALYSIS SHOWS THAT THE CAP HAS BEEN REMOVED OVER MOST OF THE CASCADES AND THE NORTH- CENTRAL MOUNTAINS...WITH ISOLATED CONVECTION BEGINNING TO FIRE IN THESE AREAS. LACKING DYNAMIC SUPPORT ALOFT IM NOT EXPECTING FOR A LARGE-SCALE CONVECTIVE OUTBREAK. BUT THE INSTABILITY SHOULD ALLOW FOR SOME FAIRLY STRONG UPDRAFTS SO ITS NOT OUT OF THE QUESTION TO SEE A FEW STORMS GO SEVERE IN THE NEXT FEW HOURS. ANOTHER MINOR WAVE IN THE SOUTHERLY FLOW IS DUE TO REACH THE SOUTHERN WA CASCADES LATE TONIGHT. DYNAMICS DONT LOOK AS STRONG AS THIS MORNINGS WAVE...BUT STILL STRONG ENOUGH TO PROBABLY INITIATE SOME LATE NIGHT/MORNING CONVECTION OVER THE CASCADES AND POSSIBLY THE WESTERN BASIN. INSTABILITY AXIS MOVES EASTWARD A BIT ON WEDNESDAY SO THE FOCUS FOR CONVECTION WILL SHIFT OVER THE CENTRAL AND EASTERN PORTION OF MY AREA. BETTER SHEAR REMAINS TO THE WEST SO THE CONVECTION STILL APPEARS TO BE MAINLY MOUNTAIN DRIVEN. FOR THURSDAY A STRONGER NEGATIVE TILT WAVE MOVES OVER THE AREA. INSTABILITY IS STRONGEST OVER THE PANHANDLE REGION WHILE THE BEST DYNAMICS WILL BE OVER MY WESTERN SECTION. HARD TO PINPOINT THE INTERSECTION OF THESE 2 AREAS AT THIS POINT. BUT THE POTENTIAL FOR STRONG/SEVERE THUNDERSTORMS EXISTS FOR THURSDAY AFTERNOON...MAINLY IN THE PANHANDLE. RJ FRIDAY THROUGH TUESDAY...GFS/ECMWF/CANADIAN/UKMET FORECAST MODELS ARE IN GOOD AGREEMENT THROUGH THE WEEKEND...THEN DIVERGE FOR MONDAY AND TUESDAY. THE FRIDAY THROUGH SUNDAY PERIOD WILL FEATURE A CLOSED LOW IN THE GULF OF ALASKA WITH A WEST TO SOUTHWEST FLOW ALOFT OVER THE AREA. SLIGHTLY COOLER ALONG WITH MUCH DRIER AND STABLE AIR WILL BE OVER THE AREA FRIDAY BEHIND THE TROUGH PASSAGE MENTIONED IN THE SHORT TERM DISCUSSION FOR THURSDAY. THEN OVER THE WEEKEND THE FLOW ALOFT WILL BECOMING SOUTHWEST WITH RISING HEIGHTS FOR WARMING BUT CONTINUED DRY. ON SUNDAY THE ATMOSPHERE WILL MOISTEN UP SLIGHTLY...WHICH COMBINED WITH WARM TEMPERATURES WILL LEAD TO MARGINAL INSTABILITY FOR A SLIGHT CHANCE OF THUNDERSTORMS FOR THE EASTERN MOUNTAINS. THEN ON MONDAY AND TUESDAY MODELS SHOW UPPER LOW IN GULF OF ALASKA MOVING INLAND...BUT HAVE LARGELY DIFFERENT TRACKS. WILL FOLLOW 06Z GFS AND ECMWF MODELS WHICH FAVOR A MORE CLIMATOLOGICAL SOLUTION...WITH THE LOW REMAINING WELL NORTH INTO CENTRAL BRITISH COLUMBIA...RESULTING IN ONLY SLIGHT COOLING FOR THE INLAND NORTHWEST. IF 12Z GFS AND 00Z CANADIAN MODEL SOLUTIONS VERIFY...MORE SIGNIFICANT COOLING WOULD BE POSSIBLE. JW && .AVIATION...VFR CONDITIONS EXPECTED OUTSIDE OF THUNDERSTORM CORES THROUGH 18Z WEDNESDAY. MOUNTAIN THUNDERSTORMS ONCE AGAIN EXPECTED THIS AFTERNOON. THUNDERSTORMS ARE ALSO POSSIBLE OVER THE WATERVILLE PLATEAU WHICH COULD AFFECT THE KEAT...KOMK OR KEPH TERMINALS. && .PRELIMINARY POINT TEMPS/POPS...
