What forecasters said that day

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

NWS Hastings, NE wrote its last area forecast discussion before this special weather statement went out at Aug 23, 3:45 AM CDT, 1 hour 21 minutes earlier.

Area forecast discussion, Aug 23, 3:45 AM CDT, 1 hour 21 minutes before
AREA FORECAST DISCUSSION
National Weather Service Hastings NE
345 AM CDT Mon Aug 23 2021

.DISCUSSION...(Today through Sunday)
Issued at 344 AM CDT Mon Aug 23 2021

A few thunderstorms continue to push through the southern part of
the forecast area early this morning. There continues to be some
development on the western edge of the storms, but that has been
less in the past hour or so.

Short term models have not been handling the redevelopment on the
western edge of the storms early this morning and all have
precipitation moving out of the area early. Have kept some
thunderstorms in through nearly daybreak, but will have to see if
they are done by then.

Clouds should diminish during the day today and temperatures will
rise into the 90s. With the humidity, the heat index values will be
around 100 degrees this afternoon. In addition, there will be an
upper level wave through central Nebraska and there is a chance for
thunderstorms this afternoon and evening in the far northeast.
Tuesday will be fairly similar to Monday for both heat and
thunderstorms. The heat and humidity will bring heat index values to
around 100 degrees again and another weak wave moving through
central Nebraska will bring another chance for some thunderstorms to
portions of the northeast and eastern part of the forecast area. The
main difference for Tuesday is there is a weak boundary that moves
through the area Tuesday afternoon and evening and should gradually
bring some relief to the area for Wednesday as the front moves into
the southern part of the forecast area. Wednesday will still have
some heat index values around 100 degrees, mainly in the southeast
part of the forecast area.

Wednesday night through Sunday continues to be an active period.
There will be several mainly weak upper level waves that move
through. Models have some on and off chances for thunderstorms but
timing them is the challenge. It will not be raining all of the
time, but the models have different timing of the waves and so have
mainly small PoPs nearly every period. Temperatures will be fairly
seasonal for this time of year.

Issued at 1229 AM CDT Mon Aug 23 2021
