YUMA COUNTY HAZARDOUS WEATHER OUTLOOK

 This hazardous weather outlook is for extreme southwest Nebraska... northwest Kansas and east central Colorado.  .DAY ONE...TONIGHT...  Isolated to scattered severe thunderstorms capable of producing dime to quarter size hail and brief, localized wind gusts up to 65 mph cannot be ruled out this evening, mainly along and west of Highway 83.  Given that significant rainfall was observed across much of the Tri- State area last week, additional heavy rain associated with thunderstorms may quickly lead to isolated flash flooding, especially along and north of Interstate 70 where recent rainfall has been heaviest.  .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH WEDNESDAY...  Scattered to numerous thunderstorms are possible over much of the area Thursday into Thursday night. A fair amount of uncertainty persists with regard to thunderstorm location and coverage. Regardless, additional heavy rain may quickly lead to flash flooding, especially in areas recently and repeatedly affected by thunderstorms.  .SPOTTER INFORMATION STATEMENT...  Spotter activation may be required.
