What happened

The episode as NWS TWC wrote it up.

The fire quickly grew to more than 4000 acres driven by wind gusts to 30 mph in dry fuels. The fire consumed 9264 acres before becoming fully contained on June 22. About 3000 acres of this total were in Mexico. Fire suppression costs tallied $1.9 million.

Area Forecast Discussion
National Weather Service Tucson AZ
207 AM MST Sun Jun 12 2022

.SYNOPSIS...Excessive heat will continue today with slightly cooler
temperatures through the first half of the week due to a weather
system passing north of the area. Isolated storms are possible again
today, then drier weather is expected through at least Wednesday.
Thereafter the chance of showers and thunderstorms increases into
next weekend.

&&

.DISCUSSION...Low level moisture moving back into the area from the
south and southwest and is fairly deep with Kitt peak showing
elevated dewpoints at just over 6,000 ft. CAM solutions suggest
isolated convection popping up around the area east of Sells then
dissipating quickly this evening. Based on that I upped POPs from the
given blend for slight chances across much of the area. Then other
than right near the SE corner of Cochise county Monday, that is
likely the last of the convection for now as developing SW flow aloft
dries out the area. Thickness values support very warm temperatures
today with 110 possible in Tucson depending on convection and
associated cloud cover.

The passing upper level system causing the SW winds aloft will also
trim temperatures back several degrees Monday and Tuesday with a
climb again into Thursday as heights rise once again. Will be pushing
110 again in Tucson Thursday, before the big change occurs.

That expected big change is due to high pressure building over the
midwest and southeast flow developing over the area which will linger
into the weekend. If this sets up as expected, this will advect Gulf
of Mexico moisture up across the region later Thursday through the
weekend which will result in scattered showers and thunderstorms
primarily Friday onward. This moisture and associated cloud cover
will help to trim afternoon temperatures back closer to normal by
Saturday. Looking like an earlier start to the monsoon season this
year is coming true.

&&

.AVIATION...Valid through 13/12Z.
Isolated SHRA/TSRA are possible again this afternoon and early
evening, especially near mountainous regions. FEW/SCT clouds between
10k-14k ft AGL this morning then SCT to locally BKN clouds 10-14k ft
SCT-BKN this afternoon and evening. Clouds clearing after 12/06Z.
Light SFC winds becoming W/NW sustained 10-15 kts with gusts up to
25 kts across the area during the afternoon. Higher gusts likely
vicinity any thunderstorms. Aviation discussion not updated for TAF
amendments.

&&

.FIRE WEATHER...Isolated showers and thunderstorms again this
afternoon and early this evening with potential for local strong wind
gusts. Otherwise expect 20-foot winds generally from the W/NW at
10-15 mph with gusts to 25 mph possible each afternoon through
Monday. The strongest winds will be across the upper Gila River
Valley where gusts could approach 35 mph briefly each afternoon with
local and brief critical fire weather conditions possible. Mostly dry
conditions expected Monday into early Thursday with lower RH levels
with gusty afternoon winds into Tuesday.

Late Thursday into the weekend it looks like we will get a
significant surge of moisture on east to southeast winds with
scattered showers and thunderstorms with wetting rains and increased
humidity levels.

.TWC WATCHES/WARNINGS/ADVISORIES...
