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 Salt Lake City, UT wrote its last area forecast discussion before this excessive heat warning went out at Jul 4, 9:21 PM MDT, 5 hours 42 minutes earlier.

Area forecast discussion, Jul 4, 9:21 PM MDT, 5 hours 42 minutes before
Area Forecast Discussion
National Weather Service Salt Lake City UT
921 PM MDT Tue Jul 4 2017

.SYNOPSIS...The ridge of high pressure aloft will strengthen
overhead through Friday, then will ever so gradually weaken and
possibly move southeast towards the four corners by early next
week. Some moisture is expected to seep in under this ridge.

&&

.DISCUSSION...The large-scale pattern this evening is dominated by
strong high pressure aloft encompassing much of the western CONUS.
This high is currently centered over Utah and will shift slightly
east tomorrow. A tongue of higher PWATs in the 0.6-0.7 inch range
was observed across northern Utah today. Given some instability
there owing in part to strong surface heating, a few thunderstorms
developed over the Uintas and central Utah mountains as well as the
far northwest corner of Utah this afternoon. These produced a few
gusts earlier in the 40-50 mph range. However, these storms are
already in the process of diminishing with the loss of daytime
heating, and expect them to completely dissipate over the next hour
or so.

Little change in the weather will be in store for tomorrow except
temperatures are expected to be a couple of degrees warmer than
today's already-hot temperatures. In addition, there will be a bit
of a drying trend from the west, so the northwest corner of Utah
should be less active convectively but the Uintas and central
mountains may see isolated thunderstorms yet again. Will continue to
see little day-to-day changes for the next several days but there is
a potential for increasing midlevel moisture towards the end of the
week.

Made minor updates to the forecast mainly to decrease PoPs and
adjust sky cover for the rest of the night.

&&

.AVIATION...Southeasterly winds are expected to become established
at the SLC terminal by 04Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
