What forecasters said that day

The local office's own words before this excessive heat 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 excessive heat warning went out at Jun 14, 3:05 AM MST, 1 hour 24 minutes earlier.

Area forecast discussion, Jun 14, 3:05 AM MST, 1 hour 24 minutes before
Area Forecast Discussion
National Weather Service Tucson AZ
305 AM MST Wed Jun 14 2017

.SYNOPSIS...Strong high pressure aloft will bring very hot daytime
temperatures especially this weekend and early next week. The
hottest locations mainly west of Tucson will approach of exceed 115
degrees Sunday into Tuesday.

&&

.DISCUSSION...A 591 dm high was centered over southern Chihuahua
Mexico early this morning, and a ridge axis extended northeastward
into the southeastern CONUS. Meanwhile, IR satellite imagery
depicted clear skies across southeast Arizona, and a few thin
cirriform clouds were south of the area across central/southern
Sonora Mexico and westward into central Baja California.

There were no major deviations via the 14/00Z GFS/ECMWF/CMC versus
their respective previous solutions regarding the expectation for
very hot daytime temperatures to occur by this weekend and
continuing into early next week. Thus, there were only very minor
temperature adjustments made to the inherited official forecast.
However, a slight downward adjustment led to the cancellation of the
Excessive Heat Watch previously in effect for western Pima County on
Friday.

At any rate, clear skies should be the rule at least through
Saturday, though perhaps a few thin cirriform clouds may move
northeastward across the area later today and tonight. High
temperatures this afternoon are forecast to be about 5-10 degrees
hotter versus Tuesday. Expect only about a degree-or-two of daily
warming Thursday through Saturday.

The GFS/ECMWF/CMC then suggest that more significant warming will
occur Sunday into Monday as the strengthening upper high becomes
centered just north or northeast of this forecast area. There were
no adjustments of consequence made to the inherited high temperature
forecast for Monday. Thus, the expectation for Tucson International
Airport official site remains at 114 degrees on Monday. The hottest
deserts west of Tucson, including Sells, Organ Pipe and Ajo, may
equal or exceed 115 degrees. High temperatures next Tuesday should
be nearly identical versus Monday, or perhaps even a degree-or-two
hotter, although this is not reflected in the current forecast.

Another concern next Monday and Tuesday will be an increase in lower
and mid-level moisture across eastern sections, and the subsequent
potential to produce high-based dry thunderstorms. Have noted that
the 14/00Z GFS has trended higher with moisture values such as
dewpoints, mixing ratios, relative humidity, precip water and model
accumulated precip versus several previous solutions. However, the
ECMWF depicted precip-free conditions to continue Monday and Tuesday.

For this forecast issuance, have opted to maintain dry conditions
next Monday, but opted to depict a slight chance of showers/
thunderstorms Tuesday afternoon/evening mainly near the mountains
east-to-south of Tucson. The concern with this scenario is that
minimal wetting rains would be the likely result, and thus dry
lightning could produce additional wildfires.

&&

.AVIATION...Valid thru 15/12Z.
Clear skies or perhaps a few thin clouds above 20k ft AGL thru the
period. Light surface winds this morning becoming W-NW 7-12 kts this
afternoon then light and variable again after 15/03Z. Aviation
discussion not updated for TAF amendments.

&&

.FIRE WEATHER...Very hot, exceptionally dry and becoming gradually
more unstable this weekend into early next week. No precipitation is
expected through the weekend. There is potential for isolated high
based thunderstorms Monday evening over the White mountains and then
south and east of Tucson Tuesday with the primary threats being dry
lightning and strong outflow winds.

20-foot winds will be typical for June through Sunday, light
drainage overnight and westerly/northwesterly 5-15 mph each
afternoon. Thereafter winds may be more easterly. Single digit min
RHs will be the rule through Monday with widespread sub 5% readings
today through Saturday. Overnight recoveries will be quite poor
especially through Thursday night with values generally 15% or less.
A slight improvement in RH levels is expected beyond Saturday.
Haines 6 conditions will slowly work across the area from the east,
starting with zones 152 & 153 Friday and Saturday, spreading west to
zone 151 Sunday and then area wide Monday Through Wednesday.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...
Excessive Heat Watch from Saturday morning through Saturday evening
for AZZ501-502-504>506-509.

Excessive Heat Watch from Sunday morning through Sunday evening
for AZZ501>506-509.

Excessive Heat Watch from Monday morning through Monday evening
