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 Twin Cities, MN wrote its last area forecast discussion before this excessive heat warning went out at Aug 18, 11:57 AM CDT, 2 hours 1 minute earlier.

Area forecast discussion, Aug 18, 11:57 AM CDT, 2 hours 1 minute before
Area Forecast Discussion...UPDATED
National Weather Service Twin Cities/Chanhassen MN
1157 AM CDT Fri Aug 18 2023

.DISCUSSION...(Today through Thursday)
Issued at 242 AM CDT Fri Aug 18 2023

KEY MESSAGES:

- Degraded air quality to continue today but will continue to improve
  into the weekend.

- Significant heat wave still expected over the weekend through the
  first half of next week, with the hottest days Saturday, Tuesday
  and Wednesday.

Not many changes to the overall 7-day forecast, which will contain a
significant heat wave along with continued dry conditions throughout.
There is a bit greater clarity on which days will have the greatest
heat, owing to a few surface frontal boundaries and the influence of
upper level ridging over the Upper Midwest.

With regards to the air quality, MN/WI air quality sensors still
indicate some particulates in the near-surface regions, but not as
dire as previously forecast. Subsidence across the region will allow
for some smoke to mix into the near-surface environment, leading to
hazy skies for at least the first half of the day. However, as winds
increase later today and the upper level pattern shifts the northwest
flow eastward, this will push the hazy conditions eastward later on
today into tonight, allowing air quality to gradually improve.

Surface high pressure atop the region this morning has led to a
calming of winds overnight which will be followed by winds picking up
from the south shortly after daybreak. This southerly surge will
advect noticeably warmer air into the region starting today. The
Upper Mississippi River valley region will just miss out on the
significantly hotter air as the H5 ridge will not quite reach this
far north or east, sitting more over the Mid-Mississippi River Valley
region through the lee of the Rockies. However, this setup will
allow for dry frontal passages atop the ridge across the northern
tier CONUS. Thus, for today, highs will top out in the low- mid 80s.
However, 90- to 100 degree temperatures will not be far away in the
western Dakotas through the central Plains. The aforementioned
ridging combined with warm sectoring ahead of a dry cold front will
push highs on Saturday into the low-mid 90s, with possibly some upper
90s in western MN. This first burst of heat will be short-lived as
the dry cold front is expected to slide east across the Upper Midwest
Saturday night into Sunday morning, bringing a modified Canadian
cooler airmass into the region for a couple days. The upper level
ridge will also retreat back to the west, thus dragging away the heat
bubble away from our region. Highs on Sunday will fall back to the
upper 70s to mid 80s.

But, again, this relief will only be short-lived as the ridge returns
eastward for Monday and making for several hot days across the Upper
Midwest for the first half of next week. Monday will be the trickiest
of the days because that is when a warm front nudges back north into
southern MN, so it depends on where exactly this front settles that
will delineate between 80s and 90s for highs. At this point,
generally-speaking, I-94 will be the line that separates 80s to the
north and 90s to the south. Come Tuesday, just about the entire WFO
MPX area will have temperatures reach the 90-degree mark, including
the potential for 100 degrees in far western MN. Wednesday now looks
to be the hottest day of all, with highs ranging from the mid 90s to
lower 100s, and these 100-degree readings could even include the Twin
Cities metro and points south and westward along the Minnesota
River. Another cold front looks to push through the region Wednesday
night into Thursday, bringing this heat wave to an end, pushing high
temperatures back into the 80s for the end of the week.

As for precipitation, dry conditions will persist through at least
the middle of next week and likely into the end of next week. This is
not necessarily due to dry air as dewpoints will rise to the mid 60s
to near 70, even with the frontal passages. Instead, this is owing to
the depth of the ridging aloft suppressing precipitation-generating
mechanisms. Strong capping, as noted in the previous discussion, will
suppress any convective potential across the Upper Midwest, denying
the chances for any rain anytime soon. Thus, have maintained a dry
forecast across the WFO MPX coverage area through the middle of next
week. With the breaking down of the ridge and additional frontal
passages at the end of next week, there might be some potential then
but no widespread rainfall is expected anytime soon.
