URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 376

NWS Storm Prediction Center Norman OK

410 PM CDT Wed Jun 28 2017



The NWS Storm Prediction Center has issued a



* Tornado Watch for portions of

  Eastern Minnesota

  Western Wisconsin



* Effective this Wednesday afternoon and evening from 410 PM

  until 1000 PM CDT.



* Primary threats include...

  A couple tornadoes possible

  Isolated very large hail events to 2 inches in diameter possible

  Isolated damaging wind gusts to 70 mph possible



SUMMARY...Thunderstorms are likely to gradually intensify through

late afternoon and early evening as some additional air mass

destabilization occurs. While the air mass will not be overly

unstable, sufficient low-level/deep-layer shear, particularly near a

warm front, will support some tornado risk aside from severe hail

and damaging winds.



The tornado watch area is approximately along and 55 statute miles

east and west of a line from 70 miles north northwest of Eau Claire

WI to 10 miles east of La Crosse WI. 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.
