   across central/north-central South Dakota through late afternoon.
   This will include the possibility of a few supercells along with
   sustained multicells capable of large hail. One or more
   east/southeastward-moving clusters could ultimately evolve by early
   evening with wind damage also being a concern.

   The severe thunderstorm watch area is approximately along and 70
   statute miles east and west of a line from 40 miles northeast of
   Aberdeen SD to 35 miles west of Chamberlain SD. For a complete
   depiction of the watch see the associated watch outline update

   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

Please visit the National Weather Service Interactive Weather Information Network (IWIN) for more information on the warnings.

For each watch, probabilities for particular events inside the watch (listed above in each table) are determined by the issuing forecaster. The "Low" category contains probability values ranging from less than 2% to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities), "Moderate" from 30% to 60%, and "High" from 70% to greater than 95%. High values are bolded and lighter in color to provide awareness of an increased threat for a particular event.
