A cold front across South Dakota triggered a line of severe thunderstorms that moved into a favorable environment, with hot temperatures in the 90s and muggy conditions, across west central Minnesota during the late evening. Straight-line winds of generally 60 to 70 mph were produced, including a measured gust of 71 mph both near Odessa and Graceville.

.DISCUSSION...
Issued at 215 PM CDT Mon Jun 20 2022

Forecast challenges revolve around severe convective chances this
afternoon through late this evening.

At 2 PM CDT, skies are partly to mostly sunny and temperatures are
warming into the 90s east of the nearly stalled out cold frontal
boundary on stiff south-southwest breezes. West of the front,
winds are out of the northwest and temperatures range from the
low 70s to the upper 80s. The front is positioned currently from
near Fargo North Dakota down to near Ipswich down to near
Chamberlain and on down to around Alliance Nebraska. A periodically
severe storm has been moving north-northeast through Dewey and
Corson counties over the past couple of hours.

The atmosphere is primed for some strong/organized convection.
More than adequate instability and increasingly favorable shear
will support severe thunderstorms by late this afternoon into this
evening. All weather hazard types are possible, although large
hail and damaging winds remain the greatest threats. There have
been more clouds around today than Saturday or Sunday, and this is
likely hampering the warm up today east of the frontal boundary.
That said temperatures across portions of northeast South Dakota
into western Minnesota have still been able to heat up into the
mid to upper 90s, with heat indices beginning to nose up to just
over the century mark. Current heat-related headlines continue,
unchanged into this evening.

Once this front begins to move east tonight, the cooler/drier air
already moving into the western forecast zones will make its way
over into the rest of the CWA, leaving Tuesday through Wednesday
dry days in the forecast, with cooler temperatures closer to
normal expected. The flow pattern aloft is still set to go semi-
zonal through Wednesday night. Then, when the mid-level dirty
ridge starts to build in on Thursday (mid-level WAA), there could
be some elevated convection around heading into Thursday
evening/night. The next cold front that moves through the region
behind this short-lived upper ridging is supposed to come through
sometime between Friday afternoon and Saturday morning. And there
could be some convection accompanying that frontal passage. Warmer
temperatures set up on Thursday into Friday prior to the frontal
passage. Then, temperatures cool back down some for the weekend.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 1244 PM CDT Mon Jun 20 2022

Terminals KABR,KATY,KPIR,KMBG

For the most part, VFR conditions will prevail through the TAF
valid period. The exception will be during the 3 to 6 hour window
this afternoon/evening when strong to severe thunderstorms develop
across central and north central South Dakota and track
northeastward through the late evening hours. Periods of MVFR cigs
and MVFR/IFR vsbys along with strong potentially damaging winds
and heavy downpours may accompany the thunderstorms. The storms
should exit the area to the east by midnight, leaving the rest of
the TAF valid period dry and breezy/windy from west-northwest
winds.
