The Tucson radar (KEMX), 51 km from the middle of the area, began a volume at 01:01 UTC, the scan nearest the moment this went out.

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

Tuscon, AZ (KDMA), launched 00:00Z, 1.0 hours before the alert went out and 90 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jul 19, 2:45 PM MST, 3 hours 13 minutes earlier.

Area forecast discussion, Jul 19, 2:45 PM MST, 3 hours 13 minutes before

Area Forecast Discussion
National Weather Service Tucson AZ
245 PM MST TUE JUL 19 2016

.SYNOPSIS...Scattered mainly afternoon and evening showers and
thunderstorms will occur again Wednesday. A decrease in coverage of
showers and thunderstorms will then prevail Thursday into this
weekend. Expect hotter daytime temperatures Thursday through
Saturday followed by a minor moderation in temperatures early next
week.

&&

.DISCUSSION...Scattered to numerous showers and thunderstorms were
occurring generally across central/eastern Pima County, southern
Pinal County and Santa Cruz County at this time. Other isolated
showers and thunderstorms were also occurring further east across
northern Graham County, and the White Mountains. The ongoing
showers/tstms will move mainly northwestward during the next few
hours, with the main threat being locally heavy rainfall and brief
gusty winds. There is still the potential for blowing dust by this
evening along the Interstate 10 corridor northwest of Tucson to
Phoenix. Various mesoscale models suggest that showers/tstms will
this evening mainly across eastern sections as the ongoing
showers/tstms decrease markedly in coverage/intensity.

Thus, the official forecast continues with scattered showers/
tstms area-wide this evening followed by a slight chance of
showers/tstms late tonight into Wednesday morning. Would not be
surprised that precip-free conditions occur across much of the area
late tonight as has generally been the case the past few nights.
However, there will still be enough moisture to support the
aforementioned scenario of a slight chance of showers/tstms.

Various mesoscale models depict similar coverage of showers/tstms
Wednesday. Have continued with scattered mainly afternoon/evening
showers/tstms again Wednesday. The 19/12Z GFS/ECMWF/CMC were similar
versus their respective solutions in depicting a gradual daily
decrease in showers/tstms to begin Thursday and continue into this
weekend. Given the progged easterly mid-level flow, precip-free
conditions area-wide should not occur as happened earlier this
month. However, moisture should remain sufficient for isolated to
scattered afternoon and evening showers and thunderstorms Thursday
through next Tuesday.

A warming trend will occur Wednesday through Friday as heights/
thicknesses increase due to a consolidation of an upper high over
southern California. Expect some minor moderation in daytime temps
early next week, but daytime temps will remain above normal.

&&

.AVIATION...VALID THRU 21/00Z.
Scattered -TSRA/-SHRA this evening followed by isolated -SHRA across
the area late tonight into Wednesday morning. Expect scattered
-TSRA/-SHRA to return Wednesday afternoon. Brief wind gusts to 45
kts and MVFR conditions will occur with stronger TSRA. Surface wind
will generally be variable in direction less than 12 kts thru the
period. Aviation discussion not updated for TAF amendments.

&&

.FIRE WEATHER...Adequate moisture for scattered afternoon and
evening thunderstorms again Wednesday. A drying trend will then lead
to reduced coverage of showers and thunderstorms Thursday into this
weekend. Moisture will remain adequate for isolated to scattered
thunderstorms early next week. Outside of gusty thunderstorm
outflows, 20-foot winds will be terrain driven and mostly less than
15 mph.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...None.
