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,
mainly over the southeast mountains. The biggest concerns with these
storms will be lightning, gusty winds, and locally heavy
rainfall. Should heavy rainfall occur over a burn scar area, flash
flooding could occur. Latest models are hinting at a storm
developing over the Pikes Peak region later this evening in which
the main risk will be heavy rain, cloud to ground lighting, wind
gusts around 40-50mph, and dime sized hail.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Isolated thunderstorms will be possible over the mountains Monday
and Tuesday with gusty winds up to 45 mph, lightning and spotty
rainfall the primary storm risks.

Moisture will increase over the region from Wednesday through
Saturday with more widespread thunderstorms expected over the
mountains. These will be capable of producing locally heavy
rainfall which could cause flash flooding of burn scars if they
are directly impacted.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this afternoon and evening near the Sangre de Cristo and
Wet Mountains, as well as the Pikes Peak region.
