What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Aberdeen, SD wrote its last area forecast discussion before this red flag warning went out at Oct 12, 12:41 PM CDT, 2 hours 36 minutes earlier.

Area forecast discussion, Oct 12, 12:41 PM CDT, 2 hours 36 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Aberdeen SD
1241 PM CDT Wed Oct 12 2022

.UPDATE...
Issued at 1237 PM CDT Wed Oct 12 2022

Aviation discussion updated below for the 18Z TAFs.

UPDATE Issued at 1102 AM CDT Wed Oct 12 2022

Winds have increased across the region with many places seeing
advisory speeds currently, mainly over central SD. Will leave the
Wind Advisory in place for today. Will see increasing fire danger
through the afternoon as humidity values drop. Given the winds and
RH expected on Thursday, went ahead and issued a Fire Weather
Watch for tomorrow, and will decide later this afternoon if it
warrants an upgrade, or pass it off to evening/overnight shift
for further evaluation. As for the rest of the forecast, highs
will top out in the 50s to around 60 degrees for most areas. Still
seeing widely scattered sprinkles/showers over the eastern CWA as
shortwave energy moves through the area. Given current/upstream
activity, as well as HRRR output, decided to expand POPs a bit
further west through the CWA and extend a bit longer into the
afternoon. May have to make further adjustments to areal coverage
and timing this afternoon based on radar trends over the next
couple hours as we still have sprinkles/showers moving southeast
across central ND.

&&

.SHORT TERM...(Today through Thursday Afternoon)
Issued at 314 AM CDT Wed Oct 12 2022

Forecast challenges remain unchanged: strength of winds today and
Thursday, and Fire Weather concerns today and Thursday.

At 2 AM CDT, temperatures were holding in the 40s and 50s on
westerly component 5 to 15 mph winds. Skies at the moment are
clear or mostly clear, but a large batch of mid-clouds are rapidly
approaching the CWA from the northwest. A regional radar mosaic
loop shows there are returns in these approaching clouds, a set-up
being aided by the approach of another 120+ knot upper level jet
streak left-exit region.

So for today, besides the smallish pops for a little bit of
measurable rain potential that have been re-arranged some to better
fit the current regional radar display and the most recent available
blend of models and cam solutions, looking at very strong northwest
winds and gusts redeveloping by late morning across much of the
western half of the CWA, with slightly lesser strong northwest winds
over northeast South Dakota and western Minnesota. Relative humidity
is now progged to drop below 25 percent this afternoon across north
central South Dakota, below 35 percent across much of the rest of
the CWA during peak heating/mixing this afternoon. Expanding the Red
Flag Warning for today all the way to the South Dakota/Minnesota
border.

After winds drop off some overnight tonight, Thursday looks like a
carbon copy of today, with winds speeds being maybe about 10 to 15
mph less, CWA-wide, while some locations over the CWA see relative
humidity values now progged to drop below 20 percent. Despite
temperatures being below 60 degrees over most of the CWA for nearly
the entire day, Thursday remains another prime candidate forecast
period for elevated fire danger. If wind/fire weather headlines did
not already pre-exist for today, Thursday would be in a Fire Weather
Watch. Perhaps one should be issued for Thursday, once today's
headlines fall off the WWA map? Nonetheless, still continuing to
message the Thursday fire weather danger/concerns here via the AFD
and in various partner support products.

.LONG TERM...(Thursday Evening through Tuesday)
Issued at 314 AM CDT Wed Oct 12 2022

50s and 60s look likely for high temperatures through the period,
with some 40 degree readings early next week over eastern SD and
western MN. The dry weather looks to continue as we remain under a
steady weather pattern with a large 500mb low over the Upper Great
Lakes and Ontario through at least Sunday night. At the surface,
reinforcing cold fronts/surface troughs will move through Friday and
again Saturday night. There will be at least some change as we move
into Monday through Wednesday of next week, with the 500mb low
shifting to the New England States and southwestern Canada. However,
dry weather looks to continue.

Fire weather wise, relative humidity values most afternoons will
fall to between 25 and 35 percent. With no relief to our continued
dry weather, winds will need to be monitored for the potential for
additional periods of elevated fire weather concerns. For example,
we'll have another day of gusty winds out of the northwest on Friday
with highs in the 60s over the southwestern half of the forecast
area. Closer to the 500mb low over northeastern MN, and a wave
rotating in from the north (along with a surface trough, a few more
clouds are anticipated Friday afternoon. Relative humidity values
will also be 5 to 15 percent higher Friday afternoon. This will keep
the elevated fire weather concerns mainly west of the Missouri River
and our southwestern counties. Will continue to highlight fire
weather concerns into Friday. We should get a break Saturday, with
most locations at or above 40 percent relative humidity and lighter
winds than the last few days.

Overall, the north to northwesterly winds should continue until
Monday when a large surface high swings across across the Northern
Plains. The high looks to sink to our south and east Tuesday with
southerly surface winds returning for Tuesday and Wednesday.
