100 PM MDT Mon Jun 17 2019 /200 PM CDT Mon Jun 17 2019/

This hazardous weather outlook is for extreme southwest Nebraska...
northwest Kansas and east central Colorado.

.DAY ONE...THIS AFTERNOON AND TONIGHT...

From late this afternoon into the evening hours, there is a marginal
to slight risk of severe thunderstorms along and west of a line from
Tribune to Brewster to Trenton. The best chance for severe
thunderstorms will be over eastern Colorado.

The main threats will be large hail and damaging winds. There will
also be a threat of locally heavy rainfall that could cause flash
flooding. Where this threat will be the greatest will be in those
locations in extreme southwest Nebraska and northwest Kansas that
received heavy rainfall last night.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH MONDAY...

On Tuesday there will still be a threat for severe thunderstorms.
However, the threat will be less than today, and confined to an area
along and south of a line from Norton to Russell Springs to Wild
Horse.

Severe weather will again be possible at the end of this week,
specifically on Friday through Sunday in the afternoon and evening
hours. It is too early to say with confidence what the severe hazards
will be, but Friday and Saturday look particularly good for the
development of severe weather, especially in northwest Kansas.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be required.
