This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This Afternoon and Tonight

Isolated to scattered thunderstorms will be possible this
afternoon and evening, with thunderstorms most numerous across the
western mountains. Locally heavy rainfall, lightning, and wind
gusts up to 45 mph will be the primary storm threats. Flash
flooding will be possible should an isolated stronger storm impact
the newer burn scars such as Spring, Chateau, Junkins or Hayden
Pass.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Increasing coverage of afternoon and evening thunderstorms can be
expected across all of South Central and Southeastern Colorado
Sunday and Monday, as monsoonal moisture moving into the Rockies,
will combine with a cold front moving across the Eastern Plains
Sunday night. The main threat from slow moving thunderstorms will
be heavy rainfall, wind gusts to around 45 mph, and dangerous
cloud to ground lightning. The potential for flash flooding will
also be a concern, especially for the newer burn scars, including
the Spring, Chateau, Junkins and Hayden Pass burn scars.

Decreasing coverage of afternoon and evening thunderstorms is
expected to start Tuesday and then continue through the end of the
work week, as drier air starts to filter into the region. There will
be enough residual moisture to support isolated to scattered
thunderstorms each day, most numerous over the higher terrain.
The main threats from storms will be locally heavy rainfall and
the potential for localized flash flooding, mainly across the
newer burn areas.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be possible through this evening in and near the burn scars.
