URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 146

NWS Storm Prediction Center Norman OK

320 PM CDT Fri Jun 1 2018



The NWS Storm Prediction Center has issued a



* Tornado Watch for portions of

  Western and Central North Dakota



* Effective this Friday afternoon and evening from 320 PM until

  1100 PM CDT.



* Primary threats include...

  A few tornadoes possible

  Scattered large hail and isolated very large hail events to 2.5

    inches in diameter likely

  Scattered damaging wind gusts to 70 mph likely



SUMMARY...In advance of an approaching upper system, the air mass

across western into central North Dakota will continue to steadily

destabilize in the wake of earlier-day thunderstorms and lingering

cloud cover. Strong deep-layer/low-level shear and a relatively

moist environment will support the potential for a few tornadoes

along with large hail and damaging winds as storms spread generally

northeastward through late afternoon and evening.



The tornado watch area is approximately along and 80 statute miles

east and west of a line from 70 miles northwest of Minot ND to 55

miles south of Bismarck ND. For a complete depiction of the watch

see the associated watch outline update (WOUS64 KWNS WOU6).



PRECAUTIONARY/PREPAREDNESS ACTIONS...



REMEMBER...A Tornado Watch means conditions are favorable for

tornadoes and 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.
