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 Twin Cities, MN wrote its last area forecast discussion before this special weather statement went out at Sep 2, 2:21 PM CDT, 3 hours 18 minutes earlier.

Area forecast discussion, Sep 2, 2:21 PM CDT, 3 hours 18 minutes before
Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
221 PM CDT Fri Sep 2 2022

.DISCUSSION...(This evening through Friday)
Issued at 221 PM CDT Fri Sep 2 2022

KEY MESSAGES:

- A few storms possible this evening across southern MN and WI.

- Dry and cooler this weekend, then trending warmer than normal next
  week.

At 2 PM this afternoon, the cold front was located from Duluth
southwest to New Ulm and Sioux City. Temperatures have risen into the
80s area wide, with dew points in the mid to upper 60s ahead of the
front. Cloud cover continues to decrease and there are yet no signs
of cu development, indicative of convective initiation. Low level
wind fields suggest the strongest frontal forcing is across northern
and parts of western WI, where the best chance for a storm or two
will be later today. CAMs are less and less optimistic for
development this far west, thus reduced PoPs to low chance at best.

Noticeably cooler and drier air will build in with high pressure
this weekend. Highs in the 70s are expected both days with lows in
the 40s, except low 50s in the metro. A couple readings in the 30s
are possible, particularly in central MN and northwest WI.

High pressure will settle from the Great Lakes to New England next
week. With the jet stream remaining well to the north, quiet
conditions will prevail (near zero PoP through Thursday) and
temperatures will trend warmer than normal in the 80s.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1202 PM CDT Fri Sep 2 2022

to north later today and this evening. A few storms may develop near
EAU this evening, but potential remains too low to introduce a
prevailing or tempo group at the moment.

maintained a dry forecast with just a wind shift.
