.DISCUSSION...
Issued at 1235 PM CDT Mon Jun 22 2026

As of a 12:30 PM CDT, temperatures in the region are in the low
70s with generally light winds out of the southeast. Some
storms will move into central and south central SD after
midnight tonight. This will provide more moisture to areas that
got rain this past weekend. Accumulations of less than a quarter
of an inch are expected.

The main story of the 7 day will be storm chances. Showers and
potentially some weak thunderstorms move across central and
northeast SD during the mid to late morning hours Tuesday along a
warm front. There is a good amount of shear at this time over
eastern SD but there is limited instability. For the afternoon,
behind the warm front, there is a good amount of instability but
limited forcing with the current timing on the cold front moving in
from ND. If the cold front moves in faster or the storms with the
warm front linger longer, we could see some stronger storms,
otherwise, the severe threat looks pretty isolated. There is a
marginal (level 1 out of 5) risk for severe storms over eastern SD
Tuesday. The main threat looks to be hail of 1 inch in diameter, but
confidence is low on hail actually growing that big. Current lapse
rate forecasts aren`t super favorable for 1 inch hail at generally
less than 7 C/km but model hodographs are fairly straight. A
shortwave moves across the area Friday bringing a chance for some
widespread rain and potentially thunderstorms. Saturday, the warm
front from an incoming strong low pressure will move across the
forecast area and start several days of thunderstorm chances. The
low is currently forecast to move across SD Sunday and the cold
front looks to be most of the way across eastern SD by Monday
morning. This is still several days out but there is a good chance a
severe outlook will be issued in the next couple days.

Temperatures through the period look to stay right around normal
with highs in the upper 70s to low 80s. Winds will be strongest
Saturday ahead of the incoming low pressure. Gusts look to be in the
30-40 mph range west of the Sisseton Hills/Prairie Coteau area.
