URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 593
NWS Storm Prediction Center Norman OK
615 PM CDT Sat Aug 17 2019

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Northwest Iowa
  Southwest Minnesota
  Northeast Nebraska
  Eastern South Dakota

* Effective this Saturday night and Sunday morning from 615 PM
  until 100 AM CDT.

* Primary threats include...
  Scattered damaging winds likely with isolated significant gusts
    to 75 mph possible
  Scattered large hail and isolated very large hail events to 2
    inches in diameter possible
  A tornado or two possible

SUMMARY...Ongoing storms across south-central/northeast South Dakota
early this evening will continue eastward, with the possibility of
additional/more isolated supercell development ahead of an evolving
cluster of storms. Some tornado risk may exist for a time,
particularly through mid-evening across southeast South Dakota.
However, the overall most common risks should be large hail and
damaging winds, which should become more of a concern later this
evening as storm mergers occur and a more organized cluster/line
develops.

The severe thunderstorm watch area is approximately along and 130
statute miles north and south of a line from 30 miles north
northeast of Worthington MN to 45 miles west southwest of Huron SD.
For a complete depiction of the watch see the associated watch
outline update (WOUS64 KWNS WOU3).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Severe Thunderstorm Watch means conditions are
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.

&&

OTHER WATCH INFORMATION...CONTINUE...WW 590...WW 591...WW 592...

AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 65 knots. A
few cumulonimbi with maximum tops to 600. Mean storm motion vector
28025.
