I have the radar image of that storm here..
Here are the SPC reports for this storm - they do mention possible high based supercells and this did produce three TVS's in its lifecycle but no tornado then I would say that confirms it also for this one. Shear and CAPE are not that good as you'll read hence no real threat of tornado activity for this system.

...GREAT BASIN...
A RATHER COOL UPPER TROUGH CONTINUES TO DIG SOUTHWARD ACROSS CA/NV THIS MORNING. STEEP MID LEVEL LAPSE RATES AND POCKETS OF HEATING WILL RESULT IN SUFFICIENT INSTABILITY FOR SCATTERED AFTERNOON THUNDERSTORMS AHEAD OF THE TROUGH ACROSS MUCH OF THE GREAT BASIN. FORECAST SOUNDINGS SHOW MLCAPE VALUES OF 500-1000 J/KG AND EFFECTIVE SHEAR OF 25-35 KNOTS. THIS SHOULD BE SUFFICIENT FOR A FEW ORGANIZED MULTICELL OR ISOLATED HIGH-BASED SUPERCELL STORMS CAPABLE OF HAIL AND GUSTY/DAMAGING WINDS. AREAL COVERAGE OF SEVERE ACTIVITY REMAINS IN QUESTION...SO WILL MAINTAIN ONLY LOW PROBABILITIES OF SEVERE WEATHER AT THIS TIME.
