URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 47

NWS Storm Prediction Center Norman OK

635 PM CDT Wed Apr 10 2019



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Southwest Iowa

  Northern Kansas

  South-central and Eastern Nebraska



* Effective this Wednesday night and Thursday morning from 635 PM

  until 100 AM CDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2.5

    inches in diameter likely

  Isolated damaging wind gusts to 70 mph possible

  A tornado or two possible



SUMMARY...Storms are likely to continue to intensify early this

evening initially across north-central Kansas, and a bit later into

northeast Kansas and southeast Nebraska. These storms could become

near-surface-based, such that a tornado and/or damaging winds cannot

be ruled out near the surface front. However, large hail will be the

most common hazard as storms otherwise expand northeastward into

south-central/eastern Nebraska through late evening.



The severe thunderstorm watch area is approximately along and 70

statute miles north and south of a line from 15 miles north of Hill

City KS to 20 miles south southeast of Omaha NE. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU7).



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

2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A

few cumulonimbi with maximum tops to 450. Mean storm motion vector

22030.
