The NWS Storm Prediction Center has issued a

SUMMARY...Storms are expected to develop through mid/late afternoon,

initially near the Montana and western North Dakota/northwest South

Dakota border region. This will include northeastward-moving

supercells capable of large hail. A tornado cannot be entirely ruled

out. The potential for severe-caliber wind gusts may also increase

through the early/mid-evening hours as storms organize and spread

into central North Dakota/north-central South Dakota.



The severe thunderstorm watch area is approximately along and 85

statute miles east and west of a line from 65 miles northwest of

Minot ND to 45 miles south southeast of Lemmon SD. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU1).



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.

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 500. Mean storm motion vector

22025.
