Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS TWC wrote it up.
Upper level trough was positioned over the central U.S. with mid-level winds very weak suggesting slow storm movement. Deep moisture was still in place as precipitable water values ranged from 1.5 to 1.7 inches and surface dewpoints were solidly in the 60's. Another active thunderstorm day occurred with one fatality due to lightning.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tucson, AZ wrote its last area forecast discussion before the first event at Aug 14, 8:55 AM MST, 4 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 855 AM MST THU AUG 14 2014 .SYNOPSIS...ANOTHER SOLID CHANCE OF SHOWERS AND THUNDERSTORMS EXISTS TODAY AND TONIGHT. WEAKER WINDS IN THE ATMOSPHERE COMBINED WITH A LITTLE LESS MOISTURE WILL LEAD TO A DOWNWARD TREND IN THUNDERSTORM ACTIVITY FRIDAY AND SATURDAY. ANOTHER INCREASE IN STORM ACTIVITY IS POSSIBLE EARLY IN THE NEW WEEK. && .DISCUSSION...COMPLEX OF THUNDERSTORMS OVER FAR SE COCHISE COUNTY INTO NE SONORA EDGING SLOWLY NW EARLY THIS MORNING. WATER VAPOR IMAGERY SHOWING DISTINCT DRYING WEST OF TUCSON...BUT THE EASTWARD PROGRESSION OF THIS DRYING HAS STOPPED. EXPECT THUNDERSTORMS TO FORM MAINLY ALONG THE TRANSITION FROM WET TO DRY AIR AND FARTHER EASTWARD. CUMULUS ALREADY BUILDING OVER THE MOUNTAINS AND COULD SEE A FEW STORMS DURING THE LATTER HALF OF THE MORNING. MID LEVEL WINDS QUITE WEAK ON 12Z TUS SOUNDING SO STORM MOVEMENT SHOULD BE FAIRLY SLOW TODAY...INCREASING CHANCES FOR MORE PERSISTENT HEAVY DOWNPOURS AND FLASH FLOODING FROM ANY OF THE STRONGER STORMS THAT DEVELOP AS PRECIPITABLE WATER VALUE WAS STILL WELL OVER 1.5 INCHES ON SOUNDING. OVERALL POP FIELDS CAPTURE THE AFTERNOON/EVENING FORECAST SCENARIO WELL...KD && .AVIATION...VALID THRU 15/18Z. ISOLATED -TSRA/-SHRA POSSIBLE THIS MORNING...THEN SCATTERED -TSRA/-SHRA WILL OCCUR THIS AFTERNOON. MVFR CONDITIONS POSSIBLE WITH STORMS AS WELL AS STRONG THUNDERSTORM OUTFLOWS. OTHERWISE...SURFACE WIND WILL GENERALLY BE LESS THAN 10 KTS WITH NORMAL DIURNAL TRENDS. AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS. && .FIRE WEATHER...PLENTY OF MOISTURE WITH SCATTERED SHOWERS AND THUNDERSTORMS TODAY. SOME DRYING WITH LESS THUNDERSTORM COVERAGE WILL THEN OCCUR THIS WEEKEND BEFORE PICKING UP AGAIN SUNDAY OR MONDAY. && .PREV DISCUSSION...DEEP MOISTURE STILL IN PLACE WITH PRECIPITABLE WATER VALUES AROUND 1.5 TO 1.7 INCHES. SURFACE DEWPTS SOLIDLY IN THE 60S. WE WILL PROBABLY SEE EASY CONVECTION INITIATION TODAY FOR ANOTHER SOLID OVERALL THUNDERSTORM DAY. WE MAY SEE STORM TRENDS START TO TAIL OFF LATER IN THE AFTERNOON AS WE START TO SEE SOME WARMING IN THE MID LEVELS. ENERGY LIFTING INTO THE NORTHERN ROCKIES AND NORTH CENTRAL PLAINS ALLOWING A SECONDARY HIGH CONSOLIDATION FURTHER WEST OVER PORTIONS OF SOUTHERN ARIZONA AND NORTHWEST MEXICO LATER TODAY AND TONIGHT. COMBINED WITH CURRENT RIDGE GEOMETRY THIS WILL TEND TO ORIENT LARGER SCALE FEATURES INTO A PARTIAL BLOCKING POSITION FOR MOST OF THE STATE. ADD A MID LEVEL DRYING TREND EATING AWAY FROM THE WEST AND SOUTHWEST FOR A GENERAL DOWNTURN IN THUNDERSTORM COVERAGE FRIDAY AND SATURDAY. THIS IS NOT A SOLID PATTERN FOR A COMPLETE SHUT DOWN IN AS MUCH AS THE DEEPER MOISTURE ISN'T BEING PUSHED VERY FAR OFF...ONLY LIMITED IN IT'S REINFORCEMENT OF THE MOISTURE INTO OUR AREA. WE WILL PROBABLY HANG ON TO ENOUGH MOISTURE FOR A BUSY INTERNATIONAL BORDER AREA. ECMWF SHOWS SOME EROSION OF THE SOUTHERN PERIPHERY OF THE RIDGE SUNDAY AND MONDAY AS HIGH PRESSURE AMPLIFIES NORTH OF OUR AREA. AS THIS HAPPENS IT BRINGS IN ANOTHER SIGNIFICANT MID LEVEL WEAKNESS FROM THE SOUTHEAST SUNDAY AND MONDAY AS WELL. NOT SURE HOW DEEP THAT WILL INFLUENCE THUNDERSTORMS INTO ARIZONA...BUT THERE'S A GOOD CHANE THE SOUTHEAST PART OF THE STATE WILL RAMP UP AGAIN FOR AT LEAST A DAY OR TWO. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. && VISIT US ON FACEBOOK...TWITTER...YOUTUBE...AND AT WEATHER.GOV/TUCSON KD

As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
