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.
Plenty of deep moisture was present with precipitable water values between 1.2 and 1.9 inches. Mid-level easterly flow was predominant in the wake of a departing inverted trough. A few slow-moving thunderstorms rolled through Southeastern Arizona with gusty winds, small hail, and heavy rain. A home in Kansas Settlement was severely damaged by microburst winds.

NWS Tucson, AZ wrote its last area forecast discussion before the first event at Jul 8, 1:40 PM MST, 4 hours 15 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
140 PM MST TUE JUL 8 2014
.SYNOPSIS...MONSOONAL MOISTURE WILL REMAIN OVER SOUTHERN ARIZONA
THROUGH THE WEEKEND WHICH WILL RESULT IN A DAILY CYCLE OF AFTERNOON
AND EVENING THUNDERSTORMS. THE FOCUS AND CHARACTER OF THE
CONVECTION WILL BE DIFFERENT EACH DAY DEPENDING PARTLY DEPENDING ON
WEAK DISTURBANCES THAT WILL MOVE ACROSS THE REGION OCCASIONALLY AND
WHAT OCCURRED THE PREVIOUS DAY.
&&
.DISCUSSION...SIGNIFICANT CONVECTION BEGINNING TO FIRE UP AROUND THE
REGION WITH THE TERRAIN BEING THE INITIAL FOCUS AS EXPECTED. STORMS
OVER THE EASTERN TWO-THIRDS OF THE AREA ARE MOVING WEST AROUND 5-10
MPH WITH THE CELLS TO THE WEST SHOWING LITTLE MOVEMENT. SHORT RANGE
HI-RES MODELS (WITH THE EXCEPTION OF THE HRRR) CONTINUE TO INDICATE
A THREAT OF A SIGNIFICANT OUTFLOWS WITH A POTENTIAL HABOOB OVER THE
NW PART OF THE FORECAST AREA LATE IN THE DAY...SO WILL STAY THE
COURSE WITH THE DUST ADVISORY. ALSO JUST NOTICED THAT SPC DECIDED
TO TOSS OUR AND PART OF THE PHX AREA INTO A SLIGHT RISK OF SEVERE
STORMS (WIND) WHICH LENDS SOME CREDENCE TO IT AS WELL. WE WILL SEE
HOW THIS ALL PLAYS OUT SOON. AGAIN TO BE CLEAR THE AREA OF MOST
CONCERN FOR BLOWING DUST IS THE I-10 CORRIDOR NW OF TUCSON.
CONVECTION SHOULD CONTINUE WELL INTO THE EVENING ALTHOUGH THE
INTENSITIES WILL DIMINISH AFTER SUNSET. BY THE EARLY MORNING HOURS
WOULD ONLY EXPECT ISOLATED LIGHT SHOWERS AND THUNDERSTORMS.
FOR WEDNESDAY...OUTSIDE OF TERRAIN NO REAL FORCING MECHANISM TO GIVE
THE CONVECTION A PUSH SO AT THIS TIME WOULD EXPECT MORE OF A DOWN
DAY WHEN COMPARED TO WHAT WE HAVE HAD LATELY. NOT TO SAY THERE WONT
BE CONVECTION...JUST LESS ABUNDANT. THE SAME BASIC IDEA FOR
THURSDAY. WITH A BIT LESS CONVECTION AND ASSOCIATED CLOUD COVER
AFTERNOON TEMPERATURES WILL BE A BIT WARMER.
FOR FRIDAY THROUGH THE WEEKEND...MOISTURE REMAINS OVER THE REGION SO
THAT INGREDIENT IS THERE...JUST NEED TRIGGERS TO FORCE/FOCUS THE
CONVECTION. LONG RANGE MODELS DO INDICATE FEATURES MOVING WEST OR
NORTHWEST ACROSS THE AREA...BUT THERE IS NO AGREEMENT ON THE
FEATURES IN TIMING OR CHARACTER SO WILL NEED TO WAIT FOR THOSE
DETAILS TO COME INTO FOCUS. OVERALL MESSAGE FOR THE EXTENDED IS
THAT IT LOOKS LIKE THERE WILL BE UPTICK IN ACTIVITY FROM A RELATIVE
LULL. CERNIGLIA
&&
.AVIATION...VALID THRU 10/00Z. ANOTHER ROUND OF MAINLY AFTERNOON
AND EVENING SHOWERS AND THUNDERSTORMS TODAY...WITH MOST ACTIVE

FOR TAF AMENDMENTS. MOLLERE
&&
.FIRE WEATHER...ANOTHER ACTIVE CONVECTION DAY THIS AFTERNOON WITH
SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS DEVELOPING ACROSS
SOUTHEAST ARIZONA. LOCALIZED HEAVY RAINS ARE EXPECTED WITH THE
STORMS DUE TO THE MOIST ATMOSPHERE AND THE SOMEWHAT SLOWER EAST TO
WEST STORM MOTION...THUS LOCAL EXCESSIVE RUNOFF PROBLEMS COULD
OCCUR. WITH A BIT MORE STORM ORGANIZATION EXPECTED TODAY THERE IS A
BETTER THREAT OF STRONG GUSTY OUTFLOWS THIS AFTERNOON. FOR THE
REMAINDER OF THE WEEK AND THROUGH THE WEEKEND...EXPECT THE DAILY
CYCLE OF SHOWERS AND THUNDERSTORMS TO CONTINUE. MOLLERE

The Tucson radar (KEMX), 77 km away, was scanning. The volume nearest the first event began at 00:57 UTC.
2 thunderstorm wind, 2 flash flood, 1 hail, 1 heavy rain. Local standard time, as filed.
A photo of nickel-sized hail was received from Picture Rocks.
A severe storm with multiple microbursts moved through the Kansas Settlement area, just south of Willcox in Cochise County. One home on E. Sulphur Springs Rd was severely damaged, and the family displaced. Pieces of a tin roof were blown off with insulation littering the ground outside the house. Rain then continued and damaged many items inside the home. Neighbors claimed to have found pieces of the roof up to two miles away on Birch Road. Several small trees and tree branches were blown down as well. There were reports to the sheriff's office of some downed power poles in the area as well.
Heavy rain caused flash flooding near the intersection of Twin Peaks and Sanders Roads.
After microburst winds ripped the roof off a home at Kansas Settlement, heavy rain damaged or ruined much of the interior of the home as well as its contents.
Thunderstorm winds snapped power poles south of Arizona City, closing three county roads.
Route 77 about 3.7 miles north of Mammoth, AZ was closed at mile marker 117 due to flash flooding. Rainfall in excess of 0.75 inches fell in a short period of time with a slow-moving thunderstorm, causing the road to flood. The same storm produced a storm total of 3.5 inches in Dudleyville, AZ.
